[0037] It should be noted that the drawings are not drawn to scale, and throughout the drawings, for illustrative purposes, elements with similar structures or functions are generally indicated by the same reference numerals. It should also be noted that the drawings are intended only to facilitate the description of preferred embodiments. Every aspect of the described embodiments is not shown in the drawings and does not limit the scope of this disclosure. Detailed Implementation

[0038] Mopeds, e-bikes, and motorcycles have short operating cycles and typically travel no more than 10 to 20 miles per day. When electrified, these vehicles can consume 20 to 50 Wh / mile in some implementations, depending on maximum speed and the total rider and vehicle weight. This presents an opportunity for solar energy to power all the daily mileage for such vehicles. Therefore, various implementations could include vehicles that are fully self-sufficient and self-charging, and can operate without an external power source, such as being plugged into an converter.

[0039] Figures 1a, 1b and Figure 2 An example embodiment 100A of a solar-powered bicycle 100 is shown, the bicycle including a frame 110 having a front end 111, a rear end 112, a top 113, a bottom 114, and sides 115. The bicycle 100 includes a pair of wheels 120, including a front wheel 120F at the front end 111 of the frame 110 and a rear wheel 120R at the rear end 112 of the frame 110. Solar panel assemblies 130 are disposed on opposite sides 115 of the frame 110.

[0040] The solar panel assembly 130 can have various suitable shapes, sizes, and configurations and may include one or more solar cells, etc. For example, Figures 1a, 1b, and Figure 2 The illustrated embodiment 100A includes a pair of solar panel assemblies 130 arranged parallel to each other on opposite sides 115 of the frame 110 of the bicycle 100. However, in some embodiments, the solar panel assemblies 130 are arranged at an angle to each other on opposite sides 115 of the frame 110 of the bicycle 100, including symmetry about a central axis (see, for example, Figures 3a, 3b, 7a, 7b, and 8). Figure 9 (etc.). Additionally, in other embodiments, the solar panel assembly 130 may be positioned at various other suitable locations on the bicycle 100, including the front end 111, rear end 112, top 113, etc. In various embodiments, the solar panel assembly 130 may cover or define a large portion of the side 115 of the bicycle frame 110, including greater than or equal to 100%, 95%, 90%, 85%, 80%, 75%, etc.

[0041] Handlebar assembly 140 extends from the top 113 of frame 110, including a stem 141 extending from the top 113 of frame 110 and a pair of handlebars 142 extending from the stem 141. Handlebar assembly 140 may include a mirror 143 and a user interface 150. In some embodiments, handlebar assembly 140 may include various suitable elements such as a clutch, throttle, one or more brake levers, etc. In various embodiments, handlebar assembly 140 may be configured to turn the front wheel 120F to steer bicycle 100.

[0042] The bicycle 100 may also include a seat 160 on the top 113 of the frame 110 near the rear end 112, one or more lights 170 at the front end 111 and the rear end 112, and one or more pedals 180 at the bottom 114 of the frame 110 extending from the side 115 of the frame 110.

[0043] Figure 2 An exploded view of embodiment 100A shown in Figures 1a and 1b is illustrated, showing that the vehicle body 110 may include a frame 210, wherein a motor 220, a control arm 230, a rear suspension unit 240, and a battery 250 may be disposed within a cavity 260 defined by the frame 210. A body cover 270 may be attached to the frame 210 at the top 113 of the vehicle body 113.

[0044] In addition to housing various suitable components of the bicycle 100, the cavity 260 of the frame 110 can provide storage for items such as a helmet 280. For example, Figure 7a shows an example where one or more of the solar panel assemblies 130 are configured to fold upwards to expose the cavity 260 within the frame 210 for storing items such as a helmet 280. Figure 7b shows an example where one or more of the solar panel assemblies 130 are configured to slide along the length of the bicycle 110 to expose the cavity 260 within the frame 210 for storing items such as a helmet 280. In various embodiments, the cavity 260 can be refrigerated and / or insulated, which may be suitable for the transport and storage of food, medicine, etc.

[0045] In other examples, one or more solar panel components 130 or other parts of bicycle 100 may be opened, folded, rolled or slid in various suitable ways to expose storage space within the body 110 of bicycle 100.

[0046] In some embodiments, the bicycle 100 may include one or more solar panel assemblies 130 configured to fold upwards or outwards when the user is not riding, allowing such solar panel assemblies 130 to be better or optimally positioned to face the sun. When riding, such solar panel assemblies 130 can be stowed, protected, etc., and can be folded downwards or folded into the side 115 of the bicycle 100. This can be achieved using hinge mechanisms in some examples, but in other examples it can be achieved using sliding mechanisms and more complex linkages. In some embodiments, the outward folding of the solar panel assembly 130 can be optimized through feedback from electronic devices, sound, or other effects that remind the user to face the panel toward the predicted (and predictable) solar path and optimal placement for solar energy collection.

[0047] For example, Figures 3a and 3b show an example of a bicycle 100 having a solar panel assembly 130 disposed on opposite sides 115 of the bicycle frame 110 and rotatably connected to the opposite sides 115 of the bicycle frame 110 via hinges 331. Figure 3a shows the solar panel assembly 130 in a downward folding configuration suitable for riding the bicycle 100, and Figure 3b shows the solar panel assembly 130 in an upward folding configuration suitable for solar charging the bicycle 100 when it is stationary. Figure 3b shows an example of a bicycle 100 including a stand 320 that can be unfolded to hold the bicycle 100 in an upright position, which may be desirable for parking the bicycle 100 and for charging the bicycle 100 via the solar panel assembly 130. Other embodiments may include foldable solar panels 130 in various other suitable locations. For example, Figure 4 An example embodiment is shown having a foldable solar panel assembly 130 disposed at the front 111 of a bicycle 100.

[0048] In various embodiments, one or more solar panel assemblies 130 of the bicycle 100 may be configured to trickle charge the battery 250. Such solar panel assemblies 130 may be rigid structures, foldable between individual batteries via hinges or along flexible lines, etc.

[0049] Some embodiments may include elements that reflect sunlight onto a solar panel assembly 130 disposed on the side 115 of the bicycle 100. Such reflective elements may include a variety of suitable materials that reflect sunlight, including metals, glass, or plastic mirrors. In some embodiments, the reflective material may include polished or unpolished metals, reflective coatings, glossy materials, etc. Such reflective elements may be flat and incorporate molded optical elements, such as Fresnel lenses, etc.

[0050] For example, Figures 5a and 5b illustrate an example of a bicycle 100 including a footrest 510 extending along the bottom 114 of the bicycle 100 on opposite sides 115 of the bicycle frame 110, wherein the footrest 510 extends generally parallel to the ground away from the bicycle frame 110 and creates a flat shelf. In some embodiments, such a footrest 510 may include a reflective material that reflects sunlight onto a solar panel assembly 130 on the opposite side 115 of the bicycle frame 110. Additionally, in various embodiments, the footrest 510 can be used for foot placement and resting during riding.

[0051] In another example, Figures 6a and 6b illustrate an example of a bicycle 100 including a folding panel 630 on an opposite side 115 of the bicycle frame 110, the folding panel being rotatably connected to the bottom 114 of the frame 110 via a rotatable coupling 631 such as a hinge. As shown in Figure 6a, the folding panel 630 can fold upward toward the frame 110 and is adjacent to a solar panel assembly 130 on the opposite side 115 of the frame 110, which can be a configuration for riding the bicycle 100. As shown in Figure 6b, the folding panel 630 can fold downward away from the frame 110 and the solar panel assembly 130 to be generally parallel to the ground. In various embodiments, the folding panel 630 may include a reflective surface configured to reflect sunlight onto the corresponding solar panel assembly 130.

[0052] In some implementations, one or more of the folding panels 630 may include solar panel assembly 130, solar cells, etc. Alternatively, the folding panels 630 may be located in other suitable locations, such as the front end 111 or rear end 112 of the bicycle 100, which may similarly correspond to the corresponding solar panel assembly 130 in such locations.

[0053] While almost any surface may have some reflectivity, it should be understood that the various embodiments discussed herein relate to reflective surfaces that reflect a significant amount of light onto one or more solar panel assemblies 130, in terms of the reflectivity and / or surface area of ​​such reflective surfaces. In other words, it should be understood that such embodiments do not directly relate to nominal reflection from slightly reflective surfaces or from small surfaces. For example, in various embodiments, the material defining the reflective surface may have a reflectivity greater than 50%, 60%, 70%, 80%, 90%, 95%, etc. Additionally, in various embodiments, reflective surfaces configured to reflect light onto solar panel assemblies 130 (e.g., footrest 510, folding panel 630, etc.) may have a reflective surface area equal to or greater than the surface area of ​​solar panel assemblies 130, or 80%, 50%, 25%, 20%, 15%, or 10% of the surface area of ​​solar panel assemblies 130.

[0054] Various other components of the bicycle 100 can be configured to be movable. For example, Figures 8a and 8b show an example in which the handlebar 141 of the handlebar assembly 140 is configured to rotate toward and away from the central axis X of the bicycle 100. Specifically, Figure 8a shows a closed configuration of the handlebar assembly 140, in which the handlebar 141 is rotated parallel to the central axis X without extending beyond the side 115 of the bicycle frame 110. Figure 8b shows an open configuration of the handlebar assembly 140, in which the handlebar 141 is rotated away from the central axis X and extends beyond the side 115 of the bicycle frame 110.

[0055] In some implementations, such a rotatable handlebar assembly 140 may include a locking mechanism that locks the handlebar 141 in a closed configuration, which is desirable for allowing the bicycle 100 to be inoperable, practically unusable, or less operable when the handlebar 141 is in the closed position, to prevent unauthorized users from using the bicycle if they cannot unlock the handlebar assembly 140.

[0056] Additionally, in some embodiments, the handlebar 141 in a closed configuration may cover or protect various components on the top 113 of the frame 110 of the bicycle 100. For example, the handlebar 141 in a closed configuration may cover or protect user interfaces (e.g., screens, buttons, gauges, etc.) or components such as power plugs, data plugs, cameras, microphones, speakers, compartments, identifiers (e.g., barcodes, QR codes, etc.), tools, switches for opening compartments, etc. Such a configuration may be desirable because such components can be protected from mishandling, theft, viewing by unauthorized users who cannot unlock the handlebar assembly 140, or exposure to adverse environmental conditions such as rain or direct sunlight.

[0057] Bicycle 100 may include various suitable safety features, including GPS-related locking (e.g., whether user interface 150 is paired with bicycle 100 on the bicycle). The bicycle 100 includes: a camera on the bicycle with facial recognition capabilities, which looks at the rider to verify the rider's identity; a safety chain location; an integrated solenoid-based lock that allows the bicycle 100 to be unlocked and operated only under required conditions (e.g., geographical location, rider identity, rider credentials, etc.); and so on. Some implementations may include one or more cameras and / or audio systems that begin recording based on detected movement (e.g., movement detected from a gyroscope, etc.). Such information may be sent to local and / or remote storage locations in various examples and used in cases where the bicycle 100 is stolen, damaged, etc.

[0058] Figure 9 An example of the elements of a dashboard 900 on the top 113 of a bicycle 100 is shown. In this example, the dashboard 900 includes a user interface 150, a camera 910, a power plug 920, and a USB port 930. In some embodiments, the user interface 150 may include elements integrated with the bicycle 100 (e.g., a screen, buttons, etc.); however, in other embodiments, the user interface 150 may include a user device such as a smartphone, smartwatch, etc. Such a user device may be operatively communicating with the bicycle 100 via wired and / or wireless communication (e.g., via USB port 930, Bluetooth connection, etc.), thereby allowing the user to interact with and / or obtain information from the bicycle 100, as discussed in more detail herein.

[0059] Camera 910 may include various suitable imaging devices, including digital cameras capable of producing images based on visible light, infrared light, etc. In some examples, camera 910 can be used to verify a user's identity, the user's license, user account (e.g., via facial recognition, scanning a driver's license, scanning a QR code), etc. This can be used to unlock bicycle 100, inspect bicycle for use 100, select a rider's user profile, confirm that the user has a valid driver's license, etc. Such example functions are discussed in more detail in this document.

[0060] The power plug 920 and / or USB port 930 allow power to be transferred to and / or from the bicycle 100. For example, in some embodiments, one or more batteries 250 of the bicycle 100 can be charged via the plug 920 and / or USB port 930. In some embodiments, external devices (e.g., smartphone user devices, laptops, lights, coolers, etc.) can draw power from the plug 920 and / or USB port 930, including potential uses as generators (e.g., as emergency generators in natural disaster scenarios).

[0061] In some implementations, plug 920, USB port 930, etc., provide the ability to connect multiple bicycles 100 together to enable direct cross-charging and / or power exchange (e.g., exchanging battery charge from one bicycle 100 to another and also exchanging battery charge to / from an external power supply and users (including external solar panels, etc.). Some implementations may include combining one or more bicycle battery systems with residential solar power for load shifting.

[0062] In terms of type and quantity, any suitable power port or plug can be used in various implementations. In some examples, the power plug or port may be of a conventional form, allowing a universal or suitable power cord to be connected to the plug or port to receive power from or supply power to the battery 250 of bicycle 100. For example, the plug or port may be a conventional power type AO, which allows the bicycle to be plugged into a conventional power source (e.g., a wall socket) to charge bicycle 100. However, in some implementations, it may be desirable to have a plug or port that is incompatible with standard power plugs. In some examples, it may be desirable to have a proprietary plug or port that is incompatible with some or all standard power plugs to prevent users from charging bicycle 100, while still allowing charging by an administrator or at an authorized charging station. For example, for bicycle 100 used in the United States, the plug may be incompatible with U.S. standard Type A and Type B plugs, which may prevent users from charging bicycle 100 via a wall socket in the United States.

[0063] Various suitable plugs or ports configured for data communication or data and power communication can be used, and USB (Universal Serial Bus) is just one example of such suitable ports, jacks, or plugs. Additionally, in some examples, power can be supplied to or obtained from the bicycle 100 via wireless power transmission such as inductive coupling. Furthermore, in some embodiments, the bicycle 100 may not have a power and / or data port or plug. For example, in some embodiments, it may be desirable that the bicycle 100 cannot be charged by a user via an external power source; instead, during normal operation, the bicycle 100 will be required to operate solely on solar power. In such embodiments, charging of the bicycle's battery 250 may be limited to battery swapping or charging that is unavailable or inaccessible to the user.

[0064] in addition, Figure 9 The example dashboard 900 should not be construed as a limitation on the various elements that may or may not be present in the dashboard 900, nor should it be construed as a limitation on the location of such elements that may or may not be located on the bicycle 100. For example, Figure 9A user interface 150 is shown located on the top 113 of the bicycle frame 110 near the front end 111, while Figures 1a and 1b show a user interface located on the handlebar assembly 140. Any suitable additional components may be part of the dashboard 900, including components such as microphones, speakers, compartments, identifiers (e.g., barcodes, QR codes, etc.), tools, switches for opening compartments, etc. Additionally, a portion or the entire dashboard 900 may be configured to be covered by a removable handlebar (e.g., as shown and discussed with respect to Figures 8a and 8b).

[0065] In various embodiments, bicycle 100 can be configured for energy recovery. For example, due to momentum transfer, most braking in various vehicles is performed on the foremost wheel. Therefore, in some examples, installing motors at all wheels can help maximize recovery benefits, where a mechanical actuator is provided on the front wheel for safety as overdrive. In some embodiments, bicycle 100 may include a front mechanical brake and / or rear electric (regenerative) actuation, and / or, in the case of front mechanical brake overdrive, bicycle 100 may have front and / or rear electric braking.

[0066] Figure 10 An example of a bicycle 100 is shown, comprising two motors 220, including a front motor 220F at a front end 111, which is associated via a line 1040 (e.g., a chain or belt) to the hub 1030 (e.g., a sprocket or pulley) and idler gear 1020 of the front wheel 120F. The bicycle 100 also includes a rear motor 220R at a rear end 112, which is associated via a line 1040 (e.g., a chain or belt) to the hub 1030 (e.g., a sprocket or pulley) and idler gear 1020 of the rear wheel 120R. In such examples, regenerative braking may be present at both wheels 120, generating energy that can be combined with solar energy generated by a solar panel array 130. In various embodiments, the bicycle may include two motors 220, one providing low torque and the other providing high speed, wherein the low-torque motor is engaged to eliminate high RPM back electromotive force or to weaken it using a dynamic magnetic field. In some examples, it may be desirable for one motor 220 to provide high torque while another motor 220 provides high speed. Some embodiments of the bicycle 100 may have a two-wheel drive arrangement, wherein regenerative braking and anti-lock braking are present at both wheels 120 to maximize (primarily) energy recovery from the front wheel 120F during braking. Other examples may include one or more mechanical brakes and one or both wheels 120 for safety, etc.

[0067] Figure 11A block diagram of a bicycle 100 according to one embodiment is shown. The bicycle includes a set of solar panel assemblies 130, including left, right, front, and rear / back solar panel assemblies 130L, 130R, 130F, and 130B, which are connected to an inverter (or one or more boost converters) 1110. The inverter 1110 can receive and modify the power generated by the solar panel assemblies 130 (e.g., convert the received power from direct current (DC) to alternating current (AC)) and provide the modified power to one or more batteries 250, in which the power can be stored. The one or more batteries 250 can be coupled to a first motor controller 1120A and a second motor controller 1120B, which can be coupled to a first motor 220A and a second motor 220B, respectively. The batteries 250 can provide power to the motor controllers 1120, which in turn can drive the corresponding motors 220. Additionally, in various embodiments, one or both of the motor controllers 1120A and 1120B can provide power back to the battery 250 (e.g., via regenerative braking). In some embodiments, the battery management system (BMS) allows one or more batteries 250 to be charged and discharged simultaneously while the bicycle 100 is in operation.

[0068] Various implementations may include periodically selecting the solar boost converter 1110 in power management within the drivetrain of the bicycle 100. In some implementations, components in the boost converter and inverter 1110 used in the solar system can be used as resistors and capacitors, which is useful for energy management in the drivetrain (e.g., short-duration high power, such as braking). For example, during regenerative braking, if the peak motor load exceeds the battery's charging capacity, the capacitors of the solar boost or buck converter can be used to absorb and dissipate energy, potentially recovering it later. In various implementations, solar energy may be regulated by the boost converter 1110 and may charge a modular, replaceable, and interchangeable battery 205, which in turn powers the drivetrain of the bicycle 100.

[0069] The bicycle 100 may also include a computing device 1130, which may be operatively connected to the solar panel assembly 130, the battery 250, and the motor controller 1120. The computing device 1130 may be any suitable device and may include a processor, memory, and a network device that allows wired and / or wireless communication with components of the bicycle 100 and devices near or away from the bicycle 100 (see, for example, Figures 13a and 13b). The computing device 1130 and / or the bicycle 100 may include any suitable additional or alternative components, such as a positioning system (e.g., Global Positioning System (GPS)), a compass, an accelerometer, a speedometer, etc.

[0070] While various embodiments of the bicycle 100 draw power solely from the battery 250 and / or current generated by one or more solar panel components 130, some embodiments may include pedals coupled to a generator that recharges one or more batteries 250 (e.g., rather than a hybrid driveline mechanically coupled to the wheels 120). In various examples, the user can select pedaling resistance (e.g., 120W or a comfortable amount or appropriate exertion), and this resistance can be controlled by a generator that can harvest and adjust the generated power for some combination of charging one or more batteries 250 or powering one or more motors 220 and charging one or more batteries 250. In some embodiments, such a configuration can significantly reduce the complexity of the bicycle 100's driveline.

[0071] The computing device 1130 in various embodiments can be configured for various types of wireless and / or wireless communications, including via Bluetooth, Wi-Fi, cellular networks, the Internet, etc. The bicycle 100 can be configured to communicate with a user's or rider's device (e.g., a smartphone, earphones, headphones, wearable devices, laptops, tablets, etc.). Additionally, in various embodiments discussed in more detail herein, the bicycle 100 can be configured to communicate with remote systems such as management servers (see, for example, Figures 13a and 13b).

[0072] The computing device 1130 can be configured to obtain data from and / or control various components of the bicycle 100, including data from the solar panel assembly 130, the battery 250, the motor controller 1120, etc. For example, the computing device 1130 can receive data from the solar panel assembly 130 related to the generated electrical power, temperature, power generation efficiency, hardware health, etc. In another example, the computing device 1130 can be powered by the battery 250 and can obtain data from the battery, including charge level, battery temperature, battery efficiency, battery health, etc. Additionally, the computing device 1120 can control the bicycle 100 via the motor controller 1120, including configuring the power usage profile of the motor 220 (e.g., power settings for maximizing bicycle performance, minimizing power usage, balancing performance and power usage, etc.), configuring motor output settings (e.g., limiting speed, limiting torque, limiting acceleration, etc.), configuring regenerative braking, etc.

[0073] This example bicycle 100 should not be construed as a limitation on various alternative systems that fall within the scope of this disclosure. For example, although Figure 11Examples include two motors 220A and 220B, but other examples can have any suitable number of motors 220, including one, three, four, five, six, seven, eight, and so on. Therefore, such a system can be configured to accommodate such a number of motors 220. Similarly, any suitable number of solar panel assemblies 130 can be present in various suitable locations on the bicycle 100.

[0074] In various implementations, time-domain multiplexing of the boost converter can save on power electronics for the multi-faceted solar panel assembly 130. For example, a problem with some solar harvesting systems is connecting all solar cells to the lowest production voltage of the cell or module. In some implementations, this can be addressed by having a separate boost converter or inverter at each cell or module, but this may incur additional costs and potentially increase the weight and size of the system. However, in some implementations, the number of boost converters / inverters 1110 in the system can be minimized by sharing the boost converter 1110 among solar panel assemblies 130 at different voltages in the time domain (e.g., charging one solar panel assembly 130 while another is filling a capacitor and vice versa, effectively amortizing the cost of the boost converter 1110 (e.g., a DC-DC converter)).

[0075] Figure 12 An example system 1200 for time-domain charging is shown, comprising a first solar panel assembly 130A and a second solar panel assembly 130B, which are operatively connected to a boost converter 1110 via respective capacitors 1210. As shown in example charging curve 1201, solar panel assemblies 130A and 130B can be used alternately to charge a battery 250. For example, the first solar panel assembly 130A may generate a larger current than the second solar panel assembly 130B (e.g., because the second solar panel assembly 130B receives less sunlight than the first solar panel assembly 130A).

[0076] The alternating charging method may include charging the battery 250 via a first solar panel assembly 130A, while the second solar panel assembly 130B charges the second capacitor 1210B. Therefore, charging can be alternating, such that the first solar panel assembly 130A charges the first capacitor 1210A while the second solar panel assembly 130B charges the battery 250. These steps can be alternated to provide alternating charging of the battery.

[0077] This type of alternating charging method can be applied to a bicycle 100 having more than two solar panel modules 130. For example, in a bicycle 100 having three solar panel modules 130, charging can alternate between the three solar panel modules in the same pattern (e.g., ABCABCABC, etc.). However, in some embodiments, alternating charging may not be applied in a set pattern, and the charging variation may be selected based on the characteristics of the respective solar panel module 130 (e.g., the amount of current generated by a given solar panel module 130). Additionally, in some embodiments, the solar panel modules 130 can charge the battery 250 in a set or dynamic group. For example, in the case of a bicycle with four solar panel modules 130L, 130R, 130F, and 130B of different sizes (see example...). Figure 11 Alternating charging of battery 250 can occur in groups (e.g., LF-RB-LF-RB-LF-RB), which can be set by default (e.g., based on the expected current from the solar panel modules) or dynamically based on current current generation conditions (such as some solar panel modules 130 being exposed to direct sunlight while others are in the shade or exposed to less sunlight). The grouping can vary in number and / or identity. For example, a dynamic alternating charging pattern could be RB-FB-LR-LB-FB-FL-LR-FB. In another example, a dynamic alternating charging pattern could be RBF-LB-FL-R-BLF-RL-FB-FBL-L.

[0078] Turning to Figures 13a and 13b, examples of solar-powered bicycle networks 1300, 1301 including one or more solar-powered bicycles 100 are shown. Figure 13a shows a first solar-powered bicycle network 1300, which includes a solar-powered bicycle 100 defining a bicycle-user-device pair 1310 and a user interface 150. The bicycle 100 and the user interface 150 are operable to communicate directly with each other via a local communication network shown in dashed lines, and the bicycle 100 and the user interface 150 can be configured to communicate with a bicycle server 1320 via a network 1330. In some embodiments, the bicycle 100 and the user interface 150 can communicate with each other via the network 1330. In some embodiments, the bicycle 100 and the user interface 150 cannot communicate via a local network connection, but can only communicate via the network 1330.

[0079] As discussed herein, the user interface 150 can be a variety of suitable devices, including smartphones, tablets, smartwatches, wearable devices, etc., and can be configured to communicate with the bicycle 100 via a variety of suitable local communication channels, such as Bluetooth, wired connections, etc.

[0080] Network 1330 may include various wired and / or wireless networks, including cellular networks, the Internet, Wi-Fi networks, local area networks (LANs), wide area networks (WANs), etc. Bicycle server 1320 may include one or more virtual or non-virtual computing systems, which may be defined by a distributed computing system or may be located in a single location.

[0081] While Figure 13a illustrates an example solar-powered bicycle network 1300 with a single bicycle 100 and a single bicycle-user-device pair 1310, other implementations may include any suitable plurality of bicycles 100 and a bicycle-user-device pair 1310. For example, Figure 13b illustrates another solar-powered bicycle network 1301, which includes a first bicycle-user-device pair 1310A and a second bicycle-user-device pair 1310B, as well as two bicycles 100 that are not part of the bicycle-user-device pair 1310. As discussed above and shown in Figure 13a, the bicycle-user-device pair 1310 and the single bicycle 100 can be operatively connected to network 1330 and bicycle server 1320.

[0082] Such solar-powered bicycle networks 1300, 1301 can be used for a variety of suitable purposes. For example, a solar-powered bicycle system comprising multiple bicycles 100 can be part of a solar-powered bicycle sharing system or a solar-powered bicycle fleet. In such examples, multiple solar-powered bicycles 100 can be distributed across one or more geographical areas (e.g., one or more campuses, cities, counties, regions, countries, etc.), and multiple users can have the right to use and ride bicycles 100. In various examples, users can select and rent bicycles 100 using their smartphones (i.e., user interface 150), ride the bicycle to a destination where they can leave the bicycle, and return the bicycle via their smartphones, allowing the bicycle to be used by other users or potentially by the same user later.

[0083] When a user rents bicycle 100, the user creates a bicycle-user-device pair 1310, which persists while the user rides bicycle 100 and continues until the bicycle 100 is returned by the user. Therefore, referring to the example solar-powered bicycle network 1301 of Figure 13, the first bicycle-user-device pair 1310A and the second bicycle-user-device pair 1310B may include bicycles ridden by the user or otherwise rented by the user. Bicycles 100 in the solar-powered bicycle network 1301 that are not part of a bicycle-user-device pair 1310 may include bicycles available for use by users who have not yet rented to define the bicycle-user-device pair 1310. Such bicycle-sharing systems or solar-powered bicycle fleets can be used by the public or by members of specific groups such as companies, universities, government departments, etc.

[0084] Solar-powered bicycle networks 1300 and 1301 can provide various desired functions, including configuring one or more bicycles 100 based on their location. For example, in various embodiments, permissible speed and / or power limits can be locked or unlocked based on the determined location of bicycle 100 and / or bicycle-user-device interface 150 of 1310 and based on laws governing the use of bicycles 100 at the determined location.

[0085] For example, the GPS module of bicycle 100 and / or user interface 150 can be queried to obtain its location and correlated with local laws, including whether bicycle 100 is on a bike lane, sidewalk, or roadway. Bicycle 100 can be restricted to low-speed (walking speed) operation, for example, when it steps onto the sidewalk, and return to full-speed, full-power operation once it returns to the roadway.

[0086] Figure 14 An example of a method 1400 for changing bicycle usage configuration based on location is shown. In some embodiments, such method 1400 may be performed entirely by bicycle server 1320, user interface 150, or other suitable means. Method 1400 begins at 1410, where an initial bicycle usage configuration is implemented. In various embodiments, such an initial bicycle usage configuration may be a default bicycle usage configuration, a recently used bicycle usage configuration, etc. For example, if a new user is renting bicycle 100, the bicycle usage configuration of the last user may be implemented as the initial bicycle usage configuration.

[0087] Returning to method 1400, at 1420, the location of bicycle 100 and / or user interface 150 is determined. For example, bicycle 100 and / or user interface 150 may use their respective GPS units to report their locations. In some embodiments, the corresponding locations reported by bicycle 100 and user interface 150 may be averaged, combined, or otherwise used to generate the determined location of bicycle 100. Alternatively, the location reported by only one of bicycle 100 or user interface 150 may be used to generate the determined location of bicycle 100.

[0088] A set of bicycle use regulations may be determined to be associated with the determined location of bicycle 100, including local, state, and / or federal laws relating to the general or specific location. For example, if the determined location is in California, USA, bicycle use regulations may include maximum speed limits as defined by federal or state laws. In another example, if the determined location is on a section of Alabama Street in San Francisco, the bicycle use regulations associated with such a location may be the maximum speed limit on that section of Alabama Street. In yet another example, if the determined location is on a section of a sidewalk near Alabama Street in San Francisco, the bicycle use regulations associated with such a location may be the maximum speed limit on that section of the sidewalk or whether bicycle 100 is permitted on the sidewalk.

[0089] Returning to method 1400, at 1440, it is determined whether the bicycle usage regulations associated with the determined location of the bicycle require or permit a change to the current bicycle usage configuration. If so, at 1450, the current bicycle usage configuration is changed to a new bicycle usage configuration that conforms to the set of regulations associated with the determined location of bicycle 100, and method 1400 loops back to 1420, where the location of the bicycle and / or user interface is determined. However, if it is not required or impossible to change, method 1400 loops back to 1420, where the location of the bicycle and / or user interface is determined.

[0090] For example, if bicycle 100 is operating in a current bicycle usage configuration that limits the bicycle to a maximum speed of 25 miles per hour (mph) and it is determined that bicycle 100 is (or will) operate on a street with a speed limit of 45 mph, it can be determined that the current bicycle usage configuration may be changed to a bicycle usage configuration that limits the bicycle to a maximum speed of 30 mph, 35 mph, 40 mph, 45 mph, 50 mph, etc. In another example, if bicycle 100 is operating in a current bicycle usage configuration that limits the bicycle to a maximum speed of 45 mph and it is determined that bicycle 100 is (or will) operate on a street with a speed limit of 25 mph, it can be determined that the current bicycle usage configuration should be changed to a bicycle usage configuration that limits the bicycle to a maximum speed of 20 mph, 25 mph, 30 mph, etc. In another example, if bicycle 100 is operating in its current bicycle use configuration that limits the bicycle to a maximum speed of 25 mph and it is determined that bicycle 100 is (or will) be in a location where bicycle operation is not permitted (e.g., on a sidewalk, in a park, in a designated restricted area, etc.), it can be determined that the current bicycle use configuration of bicycle 100 should be changed to a bicycle use configuration that requires the user to push bicycle 100 instead of riding bicycle 100, and limits the maximum speed to 1 mph, 2 mph, 3 mph, 4 mph, 5 mph, etc.

[0091] The bicycle usage configuration can be determined based on a variety of suitable factors, including whether the user holds a license or not. Figures 15a and 15b illustrate examples of different bicycle usage configuration settings based on whether the user has no license, an M1 motorcycle license, or an M2 motorcycle license. For example, under e-bike and skateboard laws, a rider without a license or proof of license may be restricted to riding below 20 mph, while if the rider presents an M1 motorcycle license, the rider may have access to greater or maximum power and speed on the bicycle. In various implementations, such settings may include maximum speed, maximum torque, location restrictions (e.g., no access to highways), or other suitable configurations of the bicycle.

[0092] In various implementations, users can prove they hold a certain license (e.g., a driver's license, M1 license, M2 license, etc.) and accordingly determine and set the bicycle usage configuration settings. Such proof may include submitting the license number and / or license image to the bicycle server 1320 and may include verifying user identity. For example, a user may provide an image of an M2 license (e.g., via a camera on bicycle 100 and / or user interface 150), and computer vision may be used to identify the license number in the image and a photograph of the license holder in the image.

[0093] The validity of the license can be verified via the license number or other suitable methods. Additionally, the identity of a given user can be identified to confirm that the user with the photo and name on the provided license image is the same user operating bicycle 100 and / or associated with the user interface 150 associated with bicycle 100. For example, an image of the user (e.g., the user's face) can be taken (e.g., via the camera of bicycle 100 and / or user interface 150) and compared with an image of a user with an M2 license to determine if the two images show the same user. If so, bicycle usage configuration can be prepared for bicycle 100 based on the user holding a valid M2 license and being associated with bicycle 100.

[0094] In some examples, users may need to prove their identity each time they rent bicycle 100 (e.g., via facial scanning); or the validity of an M2 license may be associated with a specific user interface 150 (e.g., a user's specific smartphone) for a limited or extended period, so that when user interface 150 is paired with bicycle 100 (e.g., bicycle network 1301), such bicycle 100 can be configured based on the user holding a valid M2 license, wherein the user holding a valid M2 license is based on the identity of user interface 150 and the association of a valid M2 license with user interface 150.

[0095] In some embodiments, bicycle 100 may include a remote interlock that allows bicycle 100 to be unlocked, ridden, or activated in advanced bicycle usage configurations (e.g., allowing higher speeds, power, or torque), provided that it can be proven that the rider is wearing a legal and compliant helmet based on road regulations. For example, in some embodiments, such a remote interlock may be triggered by a vision system that identifies the helmet via an identifier on the helmet (e.g., a QR code), via an RFID tag, or other electrical signals from the helmet to bicycle 100 or vice versa. Figure 19 An example implementation of a helmet 230 configured to wirelessly interact with a bicycle 100 is shown, the helmet providing bicycle usage configurations for unlocking or setting the bicycle 100.

[0096] Determining and implementing a given bicycle usage configuration can be based on a variety of suitable factors, including time, weather, lighting conditions, user history, user weight, and load on the bicycle. For example, settings such as maximum speed or maximum torque can be limited at night, in inclement weather, or in low-light conditions. Such limitations can be restrictions on all users, regardless of license status (e.g., bicycle 100 is limited to 35 mph regardless of the license held by the user) or can be reduced compared to a baseline (e.g., the maximum speed is reduced by 20% compared to the maximum speed typically allowed by the user).

[0097] In various implementations, the reported user weight and / or sensors of bicycle 100 can be used to infer the rider's body size and / or load weight, and bicycle usage configurations can be determined and implemented based on this information (e.g., configuring bicycle 100 to provide greater torque for heavier users or when carrying heavy loads on bicycle 100). Such sensors may include torque sensors, inclinometers, pressure sensors, load cells, etc. In some implementations, torque can be estimated from acceleration and power conditions, and rider weight and / or load weight can be estimated based on these conditions. Adjusting available power, torque, etc., according to rider weight may be desirable so that smaller or lighter users can have the same experience as heavier or larger users.

[0098] In some implementations, maximum speed, torque, or other settings may be limited or altered in cases where a user has a history of unsafe riding or other undesirable user behavior (e.g., the maximum speed and torque of an unsafe rider may be reduced by 20% compared to the maximum speed and torque typically permitted to a safe user). For example, a user may have a safety or ability rating associated with their user account, and such a rating can be used to determine the bicycle usage configuration of the bicycle rented to the user when bicycle 100 is available for use. Such a rating may be based on a variety of suitable factors, including speed and acceleration data from previous bicycle use indicating unsafe behavior (e.g., data from bicycle 100 and / or user interface 150); reports of accidents or violations during the use of bicycle 100 or other vehicles; reports from other users of the bicycle network 1301; reports of damage to previously rented bicycles by the user, etc. In some implementations, users may be informed of reduced features on their bicycle 100 based on such user ratings, or the reduction in features based on user ratings may be concealed from users without their knowledge.

[0099] Various implementations may include suggesting the parking location and / or orientation of bicycle 100 to maximize solar exposure when parking, thereby maximizing solar charging via one or more solar panel assemblies 130 of bicycle 100. In various implementations, the location and / or orientation of bicycle 100 may be determined based on one or more sensors of bicycle 100 and / or user interface 150. For example, sensor fusion may be used to combine GPS, magnetometer, inclinometer, and other sensor data, including the voltage of the solar panel assembly 130 itself and historical maps of solar energy resources at that particular location, to provide the user with electronic or other suitable cues regarding the optimal location and / or orientation for parking bicycle 100.

[0100] Recommendations for the desired location and orientation of bicycle 100 based on solar exposure at a given location can be determined based on a variety of suitable factors, including the expected amount of time bicycle 100 will be parked at that location; the time of day; the current and / or future position of the sun; the presence of buildings, terrain, trees, or other structures that may block the sun; historical charging or image data obtained from one or more bicycles 100 in the bicycle network; current and / or forecast weather, etc. For example, in the case where bicycle 100 is parked in an area where tall buildings may block the sun, a suitable parking location can be identified where such buildings currently do not cast shadows and where no shadows are expected (or minimal shadows compared to other locations) during the period when bicycle 100 is expected to be parked at that location.

[0101] In various implementations, a solar map indicating the sun's position during the time period when bicycle 100 is expected to be parked at that location can be compared with a map identifying the volume of the location and nearby buildings (e.g., identifying the structure of buildings in various areas, such as height and width). This information can be used to generate predictions of whether shadows are currently present or absent, and predictions of how shadows move over time based on the sun's movement. Therefore, parking locations where the expected maximum charging is likely can be identified based on changes in shadow during the time period when bicycle 100 is expected to be parked at that location. For example, in some cases, a user might receive a suggestion to park bicycle 100 at a location currently in the shade because that location is expected to receive a large amount of sunlight during the time period when bicycle 100 is expected to be parked there, even though charging may initially be lower because the location is currently in the shade.

[0102] The desired parking orientation of the bicycle 100 can be determined in various suitable ways. For example, the location of one or more solar panel components 130 on the bicycle 100 may be known, and the desired orientation can be identified based on the angle between the sun and one or more solar panel components 130 on the bicycle 100, perpendicular or at other suitable angles, which is expected to provide maximum charging over time. Such a determination may be based on the relative dimensions of the respective solar panel components 130 on the bicycle 100 and the maximum current output. The suggested orientation may be based on the expected maximum charging over a period of time. Therefore, in some examples, the suggested orientation may not currently be the optimal charging orientation or location, but rather one expected to provide maximum charging over a defined period of time. For example, a user might receive a suggestion to park the bicycle in the shade and / or at an angle that does not correspond to the current angle of the sun, but such a location and orientation is still expected to provide the maximum charge during that time period (e.g., the bicycle may be parked in the shade and / or at a certain orientation when the sun is directly overhead at noon and provides weak charge due to the angle of the sun relative to the solar panel assembly 130, but later that day the location will be sunny and the sun will be at a more suitable angle to the solar panel assembly 130, which will provide the maximum charge).

[0103] The suggested orientation of bicycle 100 may include the direction in which bicycle 100 faces (e.g., north, south, east, and west) and may include the tilt of bicycle 100. For example, where bicycle 100 includes a support (e.g., support 320 in Figures 3, 18a, and 18b) or can lean against an object, the suggested parking orientation may include a tilt angle (e.g., 15 degrees off-center from the ground and tilted eastward). For example, in some embodiments, bicycle 100 may have support 320 or other elements that provide different lean angles, and the user may receive a suggestion of the optimal lean setting for bicycle 100 from a number of available lean settings. However, as discussed herein, in some embodiments, the position, tilt, and / or the direction in which bicycle 100 faces may be automated.

[0104] The expected time periods for bicycles 100 to be parked at various locations can be determined in various suitable ways. In some implementations, historical data on the use of one or more bicycles 100 in a network (e.g., networks 1300, 1301) can be used to identify usage patterns of a group of bicycles 100 in a wide or narrow location area, or usage patterns of specific bicycles in a wide or narrow location area. For example, in locations where users ride bicycles 100 to and from get off work, park them during the day, and then ride them home after get off work, the expected time periods for bicycles 100 to be parked in such areas may be longer (e.g., several hours on weekdays) compared to locations where tourists or other users frequently rent and ride bicycles for leisure activities. Additionally, bicycles used for commuting or campus travel may have different user patterns on weekdays compared to weekends or holidays. For example, bicycles 100 in one area may be expected to be parked for extended periods in certain locations on weekends or holidays, while bicycles in another area may be expected to be parked for shorter periods on weekends or holidays due to more tourists and locals using bicycles for leisure activities in such areas.

[0105] Similarly, user patterns of a given user can be used to determine the time period during which bicycle 100 is expected to be parked at a given location. For example, if a user frequently uses the same bicycle 100 or more bicycles in a certain area, the usage patterns of that specific user can be used to estimate the likely parking time of a particular bicycle 100 or more bicycles in the given area. In one example, if a user typically rides bicycle 100 to deliver goods throughout the week, it can be determined that the bicycle will be parked for a short period during deliveries, so parking in a currently sunny location may be preferred over a location that is currently not sunny but will receive more sunlight over a longer period. Similarly, if a user is commuting to work on one or more bicycles 100 in a bicycle network (e.g., network 1300, 1301), when the user rides bicycle 100 home after get off work, it can be determined that bicycle 100 will be parked overnight until the user returns to work the next morning, or parked throughout the weekend until the commuter returns to work on Monday. Such estimated parking times can also be location-based. For example, when a user travels to and from home to a location where few other users are likely to use the bicycle, the estimated parking time may be longer compared to a location with many other bicycle users.

[0106] While some of the examples above relate to parking recommendations for users who rent and ride bicycle 100, other implementations may involve administrators moving or placing bicycles 100 within a bicycle network (e.g., networks 1300, 1301). For example, in some implementations, an administrator may receive alerts indicating that: one or more bicycles 100 are in a non-ideal location and should be moved to a new location; one or more bicycles are eligible to be moved to a new location; one or more bicycles should be prioritized for user movement or users should be incentivized to move them, etc. Similarly, when bicycle administrators are moving, placing, or otherwise distributing bicycles 100, such administrators may receive recommendations for desired parking locations and / or orientations based on sunlight exposure over a period of time.

[0107] Additionally, while the various examples discussed herein relate to recommendations for parking bicycle 100, in some embodiments, the user may receive route recommendations for optimal charging of bicycle 100 during use. For example, user interface 150 may present route information to the user, and routes identified as receiving direct sunlight may be prioritized over routes with less or reduced sunlight exposure (e.g., routes through tunnels; areas where buildings cast shadows on the route; areas where terrain such as hills or mountains cast shadows on the route, etc.). Such route selection and recommendations may utilize factors discussed herein related to generating parking recommendations, which may also include determining estimated sunlight exposure on multiple different routes and selecting one route from among those routes based at least in part on the larger estimated sunlight exposure or charging amount. For example, in some embodiments, a longer route may be recommended than another route because a longer route is expected to provide better sunlight exposure or charging amount than a shorter route.

[0108] In other implementations, route selection may be based on the state of charge of one or more bicycles in a bicycle network (e.g., networks 1300, 1301). For example, in a network including multiple bicycles 100, the state of charge of the bicycles 100 in the network can predict the future state of charge of parked bicycles in the network. If a ridden or rented bicycle 100 does not have the ideal state of charge to complete a given journey, route selection may include route selection to the location of one or more additional bicycles 100.

[0109] In some implementations, the weight borne by the bicycle 100, such as the rider and / or load weight, can be used to determine and / or adjust mileage estimates. In various examples, torque and yaw sensors allow the bicycle to infer the rider's size and load weight, and torque can be estimated via acceleration and power conditions measured by the central computer of the bicycle 100 or user interface 150. In some examples, rider weight and / or load weight can be estimated based on these conditions, and the bicycle 100 can adjust the available power and / or available torque according to the rider's weight, thus allowing smaller or lighter users to have the same experience as heavier or larger users.

[0110] For example, route selection methods may include a user-defined destination (e.g., via user interface 150, such as a smartphone), and bicycle server 1320 may determine whether any bicycle 100 near the user has a state of charge suitable for a journey to the defined destination; in some embodiments, this may include anticipated charging during riding. If so, the user may be directed to one or more suitable bicycles 100. For example, if the user is at an unsuitable bicycle 100, the user may be redirected or reminded to go to a suitable bicycle 100 near the user.

[0111] However, if there are no suitable bicycles 100 nearby to transport the user to the defined destination, it can be determined whether a suitable route might be possible by using multiple bicycles 100. For example, it can be determined whether the state of charge of the bicycles 100 near the user is sufficient to transport the user to a second vehicle 100 that can transport the user to the defined destination, or to a third vehicle 100 that can transport the user to the defined destination, or to a fourth vehicle 100, and so on. In various embodiments, determining whether bicycles on a route have a suitable state of charge may include charging as expected during riding and / or charging during the time the user travels to the bicycles (e.g., walking to the first bicycle, riding to the second bicycle, etc.). In some embodiments, if the user accepts a route with multiple bicycles 100, some or all of the bicycles 100 may be reserved for the user such that the reserved bicycles cannot be rented by other users, and therefore the bicycles 100 are only available upon the user's arrival.

[0112] One or more suggested routes, parking locations, and / or orientations of the bicycle 100 can be presented to the user via user interface 150, bicycle 100, or other suitable methods. For example, Figure 16 An example implementation of a parking suggestion display 1600 is shown, in which the parking suggestion display includes a map 1610 having multiple streets 1620, suggested parking locations 1630, and a current bicycle location indicator 1640.

[0113] exist Figure 16 In the example, the suggested parking location 1630 is shown as a profile line on map 1610; however, the suggested parking location 1630 can be shown in various suitable ways, including shading, coloring, boxing, highlighting, or other suitable indications. The suggested parking location 1630 can be presented on map 1610 in the same or different ways. For example, in some embodiments, the suggested parking location 1630 can be color-coded based on the quality of solar charging it provides. For example, a location 1630 expected to provide high-quality maximum charging for bicycle 100 can be shown in green; a location 1630 expected to provide medium-quality charging can be shown in orange; a location 1630 expected to provide low-quality charging can be shown in red; and a location 1630 expected to provide no charging or unacceptably low charging can be shown in black.

[0114] Figure 17 An example of a display 1710 that can be presented on a user interface 150 is shown, which can provide orientation and / or suggestions on how to orient the bicycle 100 to maximize solar charging via one or more solar panel components 130 of the bicycle 100. Figure 17 The example shows a display 1710 with basic orientation, but various embodiments may have any suitable indicators or suggestions regarding the orientation of or changing the orientation of the bicycle 100, such as a pointer to the direction of rotation of the bicycle 100, an indication of rotating the bicycle to a given direction and amount (e.g., turning the bicycle 45 degrees to the left to face west), etc. Additionally, as discussed herein, the user may receive suggestions to tilt the bicycle 100 at a desired angle, via elements such as bracket 320, to lean the bicycle 100 against something, etc.

[0115] For example, Figures 18a and 18b illustrate an example embodiment of a bracket 320 for adjusting the angle of a parked bicycle 100. Figure 18a shows an example of an arcuate bracket 320 defining a pair of legs 321 extending from opposite sides 115 of the bicycle frame 110, wherein the legs 321 are configured to engage the ground and hold the bicycle 100 upright, including at various angles. As shown in a close-up view of the example bracket 320 in Figure 18b, the arcuate bracket 320 may include a plurality of gear teeth 1810 that engage a worm gear drive 1820, which is rotatable to adjust the angle held by the bicycle 100, as shown in Figure 18a. Other embodiments may include a four-bar linkage, a linkage including a lead screw, or any other suitable mechanism. The bracket 320 may be configured to unfold for parking, thus engaging the legs 321 with the ground, and may be configured to retract for riding or otherwise moving the bicycle 100.

[0116] In some implementations, the bracket 320 may be configured to move the bicycle 100 to automatically track the position and / or angle of the sun, or may be set by the user parking the bicycle, based on the suggested parking angle discussed herein. Automatic tracking or angle suggestion may be based on data including solar motion from a time-based lookup table; local data collected from a network of one or more bicycles; variable voltages between the solar panel array 130 when the bicycles 130 are in different orientations; and light sensors, magnetometers, inclinometers, etc., of the bicycle 100.

[0117] An example method for automatically adjusting the bicycle 100 may include determining an ideal bicycle angle; determining whether the bicycle 100 is within tolerance of that ideal angle; and if not, changing the angle of the bicycle 100 to match the ideal angle or within tolerance of the ideal angle. Such a method may be repeated periodically such that the angle of the bicycle 100 tracks the sun over time to provide maximum charging of the bicycle 100 via one or more solar panel components 130.

[0118] As discussed herein, in some implementations, bicycle networks (e.g., networks 1300, 1301) may implement user ratings. These ratings use user behavior characteristics, including acceleration-deceleration, average speed, bicycle parking, etc., to determine whether customers exhibit characteristics such as being a safe cyclist, complying with laws and regulations, maximizing the state of charge of bicycles 100 within the network, causing damage to bicycles within the network, and being a good citizen within the bicycle network or community. Additionally, in some implementations, bicycle networks may implement incentive programs or gamification based on such user ratings, which can benefit by increasing the overall state of charge of bicycles 100 within the network; reducing damage or unnecessary wear and tear on bicycles 100; reducing fines levied on bicycle networks by local, regional, or federal jurisdictions; reducing negative public relations related to the bicycle network; reducing potential liabilities of the bicycle network; and reducing the operating costs of the bicycle network.

[0119] In various implementations, users may be rewarded or penalized based on such user ratings. For example, it might be desirable to incentivize users to park bicycles 100 to maximize their exposure to sunlight for optimal charging; therefore, users who follow instructions regarding parking location and orientation may receive a reward, while those who do not may not receive a reward or be penalized. In addition to the application to users parking bicycles 100 during bicycle return, in some implementations, users may receive alerts to move nearby bicycles 100 to correct or improve their charging potential and may receive a reward for such assistance. For example, in cases where sunlight conditions have changed or previous users have improperly parked bicycles, other users in the area may receive an alert offering a "bonus" or other reward for correcting the parking location and / or orientation of such bicycles 100. Thus, users of the bicycle network can be incentivized to care for and improve the condition of the bicycle network by actively using bicycles within or near bicycles in the network. Similarly, in some implementations, users may receive an alert that provides a “bonus” for correcting the parking location and / or orientation of such bicycles, for example, if bicycle 100 has been overturned, or parked or moved to an illegal or unsuitable location.

[0120] Rewards and / or penalties can be of various suitable types. For example, users with higher ratings may receive or unlock benefits such as reduced riding costs, lower membership fees, bike booking, ride cancellation flexibility, coupons, the ability to book 100 bikes, and extended maximum bike rental periods. In another example, users with higher ratings may receive or unlock premium bike usage configurations such as higher maximum speed, greater maximum torque, greater maximum acceleration, access to storage compartments, and access to charging ports.

[0121] In other embodiments, the bicycle 100 may have various suitable forms. For example, Figures 21a and 21b... Figure 22 , Figure 23 , Figure 24 , Figure 25 Figure 26a, Figure 26b Figure 27 , Figure 28 and Figure 29 Bicycle 100 is shown with various example implementations.

[0122] Various implementation schemes can be configured for space efficiency. For example, some implementations include bicycles 100 that can be "stacked" on each other, thus allowing many bicycles to be deployed in a small footprint. In some examples, a design that is largely hollow, like a chair, may be needed so that they can be stacked neatly together. In some implementations, bicycles 100 can be configured to be sat on (e.g., using electric wheels 120 to assist with tail-sitting). For example, Figure 20 An example of a bicycle 100 rotated from a riding configuration to a standing configuration is shown. In some embodiments, the bicycle 100 may be configured to fold flat to achieve maximum packing density in fleet and storage applications.

[0123] Various bicycle solutions can be designed to facilitate maintenance. For example, wheel alternatives that are less prone to flat, solid rubber tires and have easily accessible parts can eliminate maintenance costs.
