DETAILED DESCRIPTION OF THE INVENTION

[0014] An example provides an electric motor frame for a motorbike. The electric motor frame includes a main segment that houses an electric motor and an arm segment that extends rearward from the main segment and houses a belt drive system.

[0015] Furthermore, in some embodiments, an electric motorbike is provided that includes an integral frame surrounding a rear drive unit, the rear drive unit including an electric motor operably engaged with an electric motor.

[0016] In some embodiments, the arm segment is configured to form a swing arm of the electric motor frame when assembled to the electric motorbike.

[0017] In some embodiments, an electric motorbike is provided. The electric motorbike can include a metal frame that can be mechanically fixed together. The metal frame may include a stainless steel material that is bent during manufacturing to form a frame for the motorbike. The thickness of the stainless steel material is 2.5 mm. The panels of the metal frame can be mechanically fixed to reinforce a part of the frame. As described herein, the motorbike can include, in particular, an electric motor, a removable battery and a battery compartment, a seat adjustment actuation system, a light assembly, and a computing system.

[0018] The disclosed electric motorbike can include a plurality of computer devices that may or may not be communicatively coupled to each other for the operation of the motorbike. Exemplary computer devices include, but are not limited to, a computing device having a display and a display controller, a motor controller, a battery controller, and a passive entry security system.

[0019] In some embodiments of the disclosed technology, a computer display can include a user interface. The user interface can provide user-selectable components that provide information to a rider of an electric motorbike. The information can be obtained from one or more sensors installed on or within components of the motorbike. The sensors can include, but are not limited to, battery sensors, motor sensors, etc. For example, a temperature sensor can be used to monitor the temperature of a battery module or a motor. Readings from the sensors can be displayed via the user interface. Additionally or alternatively, the sensor readings can include information related to the battery module (e.g., charge level, remaining charge cycles, live ammeter, efficiency meter, etc.). In some embodiments, an efficiency meter that displays the operating efficiency of the electric motorbike can be displayed on the user interface. For example, the meter can display different color schemes based on the amount of power consumed during operation (e.g., red / yellow / green).

[0020] When describing examples of individual components, directional references such as "front", "upper", "forward", "rear", "rearward", "top", "bottom", and "lateral" (or "side") are made in the context of these components as operably assembled as part of an electric vehicle as described using FIG. 1.

[0021] FIG. 1 shows an electric motorbike 100 according to one or more embodiments. As described, some embodiments provide a motorbike 100 formed from modular component assemblies. Further, the motorbike 100 (or its component assembly) can be formed from manufacturing processes that optimize efficiency, as well as modularity or interchangeability of components. Further, embodiments provide a motorbike 100 formed from component assemblies that simplify or otherwise minimize the number of steps required for final assembly, where the component assembly is assembled to form a functioning bike 100 or other vehicle.

[0022] In some embodiments, the electric motorbike 100 includes a component assembly including a central frame assembly 110, an electric motor drive assembly 120, and a battery assembly 130. Further, the motorbike 100 includes a front assembly 140, a light assembly 150, and a seat assembly 160.

[0023] In the illustrated embodiment, the central frame assembly 110 includes frame segments 112, 114, 116 configured to support a rider and maintain the structural integrity of the motorbike 100 during use. Also, the central frame assembly 110 can include side segments configured to contribute to the structural integrity of the motorbike 100 and provide protection from debris during use of the motorbike 100 as well as additional support to the rider (e.g., leg positioning). In the illustrated embodiment, segments or portions of the central frame assembly 110 (such as frame segments 114, 116) directly support the seat structure 162 of the seat assembly 160.

[0024] In an embodiment, the motorcycle 100 includes a frame structure formed from sheet metal plates that are cut and / or connected to other sheet metal sheets using rivets. In some variations, the frame segments 112, 114, 116 are planarized such that a substantial portion of each individual frame segment is planar. Such planar segments can include, for example, L-shaped and U-shaped structures.

[0025] The electric motor drive assembly 120 includes a motor drive frame 122 that houses an electric motor and a drive assembly (not shown in FIG. 1). The battery assembly 130 can include a battery frame 132 and a battery module (not shown in FIG. 1). A shock absorber 144 can also be provided at the rear of the motorcycle 100 to dampen vibrations and support the rider.

[0026] In an embodiment, at least some of the component assemblies of the motorcycle 100 are formed from independent manufacturing processes. Further, in some embodiments, at least some of the component assemblies may be modular, which means that the component assemblies can be used in different motorcycles (e.g., motorcycles having different specifications, electric motors, capabilities, or dimensions) or different types of vehicles (e.g., all-terrain vehicles, snowmobiles, etc.). For example, as described in the embodiments, the electric motor drive assembly 120 can be manufactured to form an alternative type of rear drive unit for an electric vehicle.

[0027] Furthermore, in some embodiments, the assembly process of a component assembly can be modularized, which means that for a given component assembly, at least the majority of the processes or component elements used to assemble component assemblies for different products or product configurations are the same. In such cases, by making relatively minor adjustments to one or more elements of the component assembly and / or by making relatively minor adjustments to one or more of the processes in the manufacturing process of the component assembly, a component assembly as described can be manufactured for an alternative product or product configuration.

[0028] As shown in the embodiment of FIG. 3A, the electric motor drive assembly 120 houses an electric motor and a belt drive assembly. The electric motor drive assembly 120 further includes an arm segment or portion that extends rearwardly and connects to the rear wheel 104 of the motorcycle. In some embodiments, the arm segment or portion can form a swing arm of the motorcycle 100 and also houses a belt drive assembly for operating the motorcycle 100.

[0029] In an embodiment, the shock absorber 144 can be modularized or assembled such that components can be replaced, rearranged, or sized. The ends of the shock absorber 144 can be connected to segments of a frame assembly for a motorcycle. The shock absorber 144 can be mechanically connected to the frame assembly of the motorcycle at any of a plurality of locations. For each such connection location, a corresponding set of openings can be provided in the corresponding frame segment of the motorcycle that are aligned to receive a rod, bolt, or other connector member. Such connector members can serve to secure the shock absorber 144 to the frame assembly of the motorcycle. In one implementation, a set of three opening pairs are formed in the central frame assembly 110, and each opening pair is aligned to receive a connecting crossbar that is also secured to the end of the shock absorber 144. The set of openings can be arranged in an arc such that the shock absorber 144 is provided at different heights and distances from a base member to which it is secured. In the manufacturing process, the shock absorber 144 is selected with respect to attributes such as size, damping, and stiffness. Based on its dimensions, the shock absorber 144 is secured to an anchor (base) and connected to the frame assembly of the motorcycle through openings suitable for the particular attributes of the shock absorber 144. The shock absorber 144 can also be removed non-destructively from the motorcycle 100 for replacement parts that include replacement parts having a different set of attributes.

[0030] In an embodiment, one or more of the frame segments 112, 114, 116 can provide a set of fastener elements 115 that are user-friendly. In some embodiments, the fastener element 115 is a torque lock receptacle. In an implementation, the set of fastener elements includes one or more through-hole nuts that are press-fitted into the openings of the frame segment 114 during the manufacturing / assembly process. A user can use the fastener element 115 to connect an accessory device (e.g., a travel bag or a basket) to the frame of the motorcycle 100. In this way, the user can attach and detach the accessory device to / from the motorcycle. In an embodiment, the fastener element 115 can receive a threaded insertion connector (e.g., a bolt). The accessory device can include a threaded connector positioned to be aligned and connected with the motorcycle 100. As an example, the fastener element 115 can correspond to a stainless steel through-hole nut screw manufactured under the trade name PEM.

[0031] 〔Frame Assembly Process〕 FIG. 2A shows a frame assembly process for manufacturing a frame or a frame component for a vehicle component assembly according to one or more embodiments. A process as described in FIG. 2A can be used for the assembly or manufacture of a component assembly as shown and described in FIG. 1 and other embodiments.

[0032] (210) In this step, the attributes of the frame of the component assembly are determined. For example, the dimensions, weight, strength attributes, and other attributes of the frame are predetermined based at least in part on the requirements of the component assembly and the vehicle that receives the component assembly.

[0033] In (220), a plate configuration sub-process is executed to determine the plate configuration of the frame. The plate configuration of the frame can identify the number of plates, the attributes of the plates (e.g., the material and thickness of the plates), the shape of the plates, and the overlap strips of the plates. Each identified plate of the plate configuration can be formed from sheet metal of a selected material and thickness.

[0034] In an embodiment, the plate configuration sub-process generates specifications for the pattern of plate elements, which include dimensional specifications that identify the overall plate shape (e.g., shape and size) and the overlap strip dimensions for the individual plates of the pattern. Further, at least some of the plates of the shape include one or more overlap strips, and each overlap strip identifies the boundary of the area of the plate surface that contacts and adheres to the overlap strip of another plate of the pattern. As an example, the plates are pre-manufactured from a material (e.g., a type of steel alloy) selected to have a specific thickness, dimensions, shape (e.g., flat panel, curved panel, etc.). The desired plate shape can be realized, for example, using a CNC machine that cuts, bends, and folds the sheet metal into plates of the desired shape.

[0035] In some embodiments, the plate configuration sub-process can determine the shape (e.g., cut, bend, fold) and relative position of the individual plates to obtain a desired three-dimensional frame having a desired shape and a set of attributes. The plate pattern thus obtained can define a shell having voids inside, and the individual plates can be joined to other plates according to a pattern that forms part of a one-dimensional, two-dimensional, or three-dimensional shell. In this way, the individual plates can be said to be "sewn together", which means that the plates are joined to other plates of the frame in sequence and / or as puzzle pieces. The plate pattern thus obtained can identify overlap strips where the individual plates are joined to other plates using an adhesive.

[0036] In an embodiment, the plate configuration sub - process is computer - implemented. The computer - implementation process can further optimize the design of the frame components for purposes such as minimizing plates or materials and / or reducing the area of overlap strips.

[0037] (222) In this case, rivet holes are formed along the overlap strips of the individual plates. The rivet holes can be spaced or otherwise positioned based on the desired frame specifications. In an embodiment, the rivet holes are realized simultaneously when the sheet metal is cut and formed (e.g., by a CNC machine).

[0038] (230) In this step, the plates are joined along their respective overlap strips. The plates may be joined, for example, according to a sequence in which the individual plates are adhered to other plates along a predetermined overlap strip. The plates may also be adhered such that the rivet holes of the plates to be joined are aligned or overlap to form combined rivet holes. An appropriate manufacturing adhesive can be selected to join the plates.

[0039] (240) In this step, rivets are inserted into the combined rivet holes of the plates to be joined. The rivets may be mechanically inserted while the adhesive joining the plates is curing. For example, the rivets may be inserted several seconds to several minutes after the plates are joined. The mechanically inserted rivets can be inserted so as to extrude the adhesive between the plates.

[0040] (250) Before the assembly of the frame is considered complete, the frame is cured for a predetermined period (e.g., 24 hours) together with the inserted rivets.

[0041] FIG. 2B shows the structure of an exemplary front frame segment, according to one or more embodiments. The front frame segment 270 (which may correspond to the central frame 110 of FIG. 1) supports the front assembly 140 of the motorcycle 100. In an example, the front frame segment 270 receives the head tube component 244 of the motorcycle 100. The head tube component 244 can provide a handlebar 245, user controls, forks, wheel assemblies, and other components, as shown and described in the example.

[0042] In an example, the front frame segment 270 can be designed to have an overall shape and a set of attributes (such as material, strength, overall dimensions, etc.). A plate configuration sub-process is performed to identify the plates 272, 274, 275, 276, 278. Each plate 272, 274, 275, 276, 278 can have a specific shape formed by cutting and bending the end faces. Further, each plate 272, 274, 275, 276, 278 can include an overlap strip where the individual plates join to other plates. The plates 272, 274, 275, 276, 278 can be joined according to a plate pattern where the plates form part of the overall frame design. Rivets 271 are formed in regions that coincide with the overlap strips (the adjacent parts where the adjacent plates 272, 274, 275, 276, 278 adhere to each other). As described, the rivet holes may first be formed along the overlap strips, and when the plates are joined using an adhesive, the rivets are mechanically inserted into the aligned rivet holes of the joined plates. The resulting structure forms a frame (e.g., the central frame 110) for the motorcycle 100 or other vehicle.

[0043] Furthermore, in the illustrated embodiments, the connector holes 279 can be formed within the front frame segment 270 that receives the cross bolts or rods. The connector holes 279 can be aligned with similarly shaped holes in another assembled segment such that the respective connector holes of the aligned frame segments can receive a connector rod (e.g., bolt). In this way, a connector rod or bolt can be passed through the connector holes 279 and fixed in place through the use of fasteners, etc.

[0044] 〔Modular Head Tube Assembly〕 Referring further to FIGS. 2B - 2D, an embodiment provides that the front assembly 140 includes a modular head tube component 290 that can be assembled to the frame assembly of the motorbike 100 either during the manufacture of the electric motorbike or afterwards (e.g., by an end - user, etc.). Among other advantages, modularization allows the head tube component 290 to be assembled to the motorbike 100 without welding. As with other embodiments, welding complicates the manufacturing process by reducing the allowable tolerances between component alignments and by requiring the use of specialized equipment. Further, modularization allows different types of head tube components 280 to be equipped to a given type of frame assembly (e.g., frame assemblies of different sizes or types of motorcycles). Similarly, a given type of head tube component 290 (e.g., length, head angle, presence or absence of suspension, type of suspension, etc.) can be assembled to different types of frame assemblies.

[0045] Referring to FIGS. 2B and 2C, the front frame segment 270 includes a front extension 282 that extends forward from each base portion 284. The front extension 282 can be at least partially defined by plates 272 (side plates), 273 (side plates), 274 (bottom plate), 277 (top plate). In the vicinity of the frontal end 281 and / or thereof, the front extension 282 can include an opening for receiving the body 292 of the head tube component 290. In some implementations, the top plate 277 includes a circular opening sized to receive the top end portion 294 of the head tube member 292. In some embodiments, the head tube member 292 passes through the openings of the top plate 277 and the bottom plate 274 and is fixed there by a fixture without welding.

[0046] As shown by FIG. 2D, the head tube component 290 includes a body 292 having a top end portion 294 and a bottom end portion 296. A set of plate connectors 295 can be provided at the top end portion 294. In the illustrated embodiment, a set of plate connectors 295 includes plate segments that individually define semi-circular openings. Each plate connector 295 can include a rivet hole 299 that is aligned with and overlaps a respective rivet hole in the top plate 277. The plate connectors 295 can be fixed to the top plate 277 such that the two plates define an opening for receiving the body 292 of the head tube component 290. The inner thickness of each plate connector 295 can be configured (e.g., threaded) to secure the top end portion 290 of the head tube component 290. According to some embodiments, during assembly, the main tube 292 is inserted from the lower part of the front extension 292 such that the top end portion 284 passes through the top plate 277 and is then attached by the plate connectors 295. The plate connectors 295 can be fixed to the top plate 273 of the front extension 282.

[0047] Further, referring to FIGS. 2C and 2D, in an embodiment, the bottom end portion 296 of the head tube component 290 can be fixed to the bottom plate 273 of the front extension 282 by a collar 298 or a color assembly. In an embodiment, a color extension 297 can extend from the bottom plate 273. The bottom end portion 296 of the head tube component 290 can be received in the color extension 297. The bottom end portion 296 can be threaded together with the collar 298. As an additional or alternative example, the bottom end portion 296 can extend from the bottom plate 273 such that a threaded portion is exposed to receive the collar 298. The collar 298 can be mechanically connected to attach the bottom end portion 296 to the underside of the bottom segment 273. In this way, the head tube component 290 can be assembled and attached to each frame assembly. Further, in some embodiments, the head tube component 290 can be removably removed from the frame assembly of the motorcycle 100 non-destructively by applying a mechanical force (e.g., torque to the collar 298 and the top end portion 294).

[0048] 〔Electric Motor Drive Assembly and Frame〕 Figures 3A-3C show an electric motor drive assembly 120 according to one or more embodiments. Referring to FIG. 3A, the electric motor drive assembly 120 is shown in an assembled state on an electric motorbike 100. The electric motor drive assembly 120 includes a motor drive frame 122 configured as a shell having a main segment 310 and an arm segment 320. The main segment 310 is configured to house an electric motor, and the arm segment 320 is configured to house a belt drive assembly. In some variations, the main segment 310 is sized to house any of a plurality of electric motors, or a combination of electric motors of various dimensions, outputs, and performance attributes. The arm segment 320 extends rearwardly from a side portion of the main segment 310. In some embodiments, the arm segment 320 is sized and configured to form a swing arm of the electric motorbike 100. The electric motor drive assembly 120 can also form a support structure for a shock absorber that supports a seated rider.

[0049] FIG. 3B is an exploded perspective view of the electric motor drive assembly 120 with a side portion of the outer shell cut away to illustrate the operation of the belt drive system. The main segment 310 includes a cylindrical body having an end segment 302. The main segment 310 is configured to house an electric motor 352 (see FIG. 3C) that powers the motorbike 100. Accordingly, the main segment 310 is sized to hold one or more electric motors 352 of a desired dimension. Further, the arm segment 320 extends rearwardly along the side of the electric motorbike 100 and engages the rear axle and wheel assembly of the motorbike 100. The arm segment 320 houses a belt drive system 354 that, in combination with the electric motor 352, forms a rear drive unit of the motorbike 100.

[0050] In the embodiment, the shaft 325 of the electric motor 352 (FIG. 3C) extends from at least one of the end segments 312 of the main segment 310 into the interior of the arm segment 320 and engages with the belt drive assembly 354. The shaft 325 engages with a shaft wheel (not shown) connected to the flywheel 345 by a belt 355. The flywheel 345 is connected to or forms part of the back wheel assembly of the motorcycle 100. When powered by the electric motor 352, the belt drive assembly drives the rear axle to rotate the rear wheel and move the motorcycle 100 forward.

[0051] The electric motor drive assembly 120 also includes a parallel frame segment 342 that extends rearwardly on the opposite side of the arm segment 320. Further, the arm segment 320 and / or the frame segment 322 can also shield the belt drive system, the axle, and the wheels of the motorcycle 100 from debris during use of the motorcycle 100.

[0052] Referring to FIG. 3B, the main segment 310 is integrated with a frame support structure 312 that connects the electric motor motorcycle drive assembly 120 to another frame structure of the motorcycle 100. The frame support structure 312 includes a support flange 318 and an opening 319 for receiving the connecting rod 316. In the embodiment, the opening 319 is aligned with a corresponding opening of the central frame assembly 110 that receives the connecting rod 316. In this way, in the embodiment, the central frame assembly 110 can be firmly assembled to the electric motor drive assembly 120 using a single connecting rod 316.

[0053] Figure 3C is an exploded perspective view of the electric motor drive assembly 120 shown with a portion of the outer casing cut away. As shown, the electric motor 352 is mounted between the support flanges 318, along with a shaft 325 that extends laterally to engage a shaft wheel of the belt drive assembly 354. In the embodiment shown in Figure 3C, the motor 352 includes fins 357 or other features that provide a heat sink for the operation of the motor. The flywheel of the belt drive assembly 354 engages the accelerator 305 of the rear wheel assembly. When the motor operates, the shaft wheel engages and rotates the flywheel 345 via the connecting belt 355. Also, the flywheel 345 is connected to the rear accelerator 305 to drive the rear wheel of the motorcycle 100. The frame segment 342 extends from the other lateral portion of the body 310 and can passively engage the rear accelerator 305. In this way, the frame segment 342 supports the electric motor drive assembly 120 during the use of the motorcycle 100 and also provides a cover and protection against debris.

[0054] According to an embodiment, the motor drive frame 122 is formed as an integrated assembly. In some embodiments, the motor drive frame is formed from cast aluminum. In a variant, the electric motor drive frame 122 is assembled using a pattern of plates as described in the embodiments of Figures 2A and 2B.

[0055] In some embodiments, the electric motor drive assembly 120 is assembled during a manufacturing process that is separate and independent from the manufacturing process of assembling the motorbike 100 or other components of the vehicle. Further, the electric motor drive assembly 120 can be modularized, for example, to accommodate different sizes of electric motors or internal components. In a variant, for example, the assembly process of the electric motor drive assembly 120 can be modularized in that the design parameters of the electric motor drive assembly 120 can be changed. For example, the arm segment 320 can be made longer or shorter to accommodate different form factors of the electric vehicle. Further, by adjusting the length of the arm segment 320, belts of different sizes or flywheels of different size dimensions can be used. Among other advantages, modularizing the electric motor drive assembly 120 and / or the assembly process such as described enables a manufacturing or assembly process that can produce not only different types of products (e.g., electric motorbikes, all-terrain vehicles (ATVs), go-karts, etc.) but also various variations of products (e.g., the electric motorbike 100 having different performance attributes).

[0056] 〔Battery Assembly and Frame〕 Figures 4A - 4D show a battery assembly 140 and a battery frame 142 according to one or more embodiments. The battery frame 142 can be manufactured through the processes as described in FIGS. 2A and 2B. Thus, the dimensions and other attributes of the battery frame 142 can be determined based on, for example, the size of the battery module 410 held within the frame 142. The battery frame 142 can be formed from one or more sheets of sheet metal that are cut, bent, and folded according to a predetermined design. Rivet holes can also be formed simultaneously in the regions where the plates overlap. Thereafter, an adhesive can be applied to those regions of the individual plates, and the plates can be overlapped along those regions according to the plate pattern of the battery frame design. The plates may be adhered to each other along the overlapped regions, and the holes on each plate are aligned to receive corresponding rivets. The rivets can be mechanically inserted and the adhesive can be fully cured.

[0057] FIGS. 4B and 4C illustrate (shown by phantom lines) a battery module 410 housed within the battery frame 142. The battery module 410 can be inserted into and electrically connected to the wires of a power bus that powers the components of the motorbike 100. In particular, the battery module 410 can power the electric motor, lights, and auxiliary components of the motorbike 100. Further, a recharge circuit and a socket for receiving an input power supply can be provided inside the battery frame 142.

[0058] Figure 4D shows an example where the battery frame assembly 142 is removable from the rest of the motorcycle 100. The battery frame assembly 142 can be provided on a wheel and a telescopic arm 444 (or handle) that can extend when the battery frame assembly 142 is removed from the motorcycle 100. When the battery frame assembly 142 is removed, the user can extend the telescopic arm and pull the battery frame assembly 142 together with the battery module 410. Similarly, the user can retract the telescopic arm, connect the battery frame assembly to the motorcycle 100, and electrically connect the battery module 410 to the power bus of the motorcycle 100.

[0059] 〔Seat Assembly〕 Figures 5A through 5C show an exemplary motorcycle 100 having an adjustable seat assembly according to one or more embodiments. Figure 5A is a perspective view from below of a motorcycle 100 including a seat assembly 160 having a seat 162 and a pair of pneumatic cylinders 520. The seat 162 (and the user on the seat) can be directly supported by the central frame assembly 110. Further, each of the pneumatic cylinders 520 includes a bottom end 519 that connects to a crossbar 515 of the central frame assembly 110. In the example shown, the bottom end 519 can correspond to the engagement point of the insertion rod of each pneumatic cylinder 520.

[0060] Each pneumatic cylinder 520 includes an outer cylinder 522 and an insertion rod 524 that moves axially within the volume of the outer cylinder between different axial positions. The insertion rod 524 of each pneumatic cylinder 520 is connected to the crossbar 515, and the base of the cylinder 520 is connected to the bottom end 521. In a variant, the configuration of the pneumatic cylinder 520 can be different (for example, the insertion rod 524 is connected to the lower side 521 of the seat 162). The insertion rod 524 is partially inserted into the sealed chamber of the outer cylinder and is movable between various vertical positions based on the distribution of gas / fluid within the sealed chamber. Each pneumatic cylinder 520 can further include a control mechanism that controls the axial position of the insertion rod 162, causing a relative axial repositioning of the insertion rod 524 with respect to the outer cylinder 522. For example, the control mechanism can be operated to move the insertion rod 162 axially outward relative to the outer cylinder 522 (e.g., toward the crossbar 515), thereby causing the pneumatic cylinder 520 to push out the lower side of the seat 162 and further lift the seat. Also, the control mechanism can be operated to move the insertion rod 162 axially inward relative to the outer cylinder 522, thereby lowering the height of the seat 162.

[0061] In an embodiment, the pneumatic cylinder 520 is a gas cylinder, and the position of the insertion rod 524 can be controlled by a mechanical lever that causes the desired flow of gas within the sealed chamber. Further, in some embodiments, the position of the mechanical lever can be controlled by a control cable disposed on or near the handlebar of the motorcycle 100. Alternatively, the control cable can be provided at an alternative location on the central frame assembly 110 or the seat assembly 160. In a variant, the pneumatic cylinder 520 utilizes an alternative form of pneumatic pressure, and the control mechanism can be electrically actuated to cause the movement of each insertion rod 524.

[0062] FIG. 5B is a side view of the motorcycle 100 showing the range of movement of the seat 162 in response to the adjustment of the pneumatic cylinder 520. In the illustrated embodiment, the seat 162 of the seat assembly 160 can move from the original position (O) to the adjusted or raised position (A) and return from the adjusted or raised position (A) to the original position (O). In some embodiments, such as those shown in FIGS. 5A and 5B, the movement of the seat 162 can follow an arc.

[0063] The embodiments of FIGS. 5A and 5B show a motorcycle 100 including a pair of pneumatic cylinders 520, but in alternative embodiments, more or fewer gas springs may be used. Further, in other alternative embodiments, an electromechanical actuator may be used instead of the gas spring 520 to enable the seat 162 to rise to the adjusted position (A) and / or descend to the original position (O).

[0064] FIG. 5C is an exploded perspective view of a seat assembly 160 according to one or more embodiments. The seat assembly 162 includes a seat 162, a pneumatic cylinder 520, and a base structure 528. The seat assembly 160 can be assembled in a process separate from other component assemblies of the motorcycle 100. The elements of the seat assembly 160 can be modularized so that various seat assemblies can be easily assembled to the same motorcycle 100 or vehicle design, and so that seat assemblies of the same design can be assembled to various vehicle designs. To assemble the seat assembly 160, the base structure 528 can be assembled, for example, through a process as described in FIG. 2A. Further, the dimensions of the base structure 528 can be changed to allow for various seat dimensions and designs. Further, the seat 162 can have its attributes (e.g., size, cushion thickness, etc.) changed for each motorcycle 100 (or vehicle). Further, when modularizing the seat assembly 160, the manufacturing process of the seat assembly 160 and / or elements of the seat assembly 160 can be changed, for example, based on the dimensions of the base structure 528 (which can vary based on user dimensions or preferences, vehicle size or type, etc.). Even further, the type of pneumatic cylinder 520 and / or the type of control mechanism can also be changed based on various factors such as dimensions or user preferences, or the type of motorcycle 100.

[0065] 〔Light Assembly〕 Figures 6A and 6B show a light assembly 150 according to one or more embodiments. The light assembly 150 includes a pair of light components 630, 632, where one of the light components (e.g., the top light component 632) is auxiliary (e.g., high beam, fog light). The light assembly 150 includes a housing 610 that holds the light components 630, 632. The housing 610 can be shaped to include a base portion 612 dimensioned to abut against (or between) opposing bars of the handlebar assembly 140. The housing 610 can further include wings 614 that extend laterally outward from the base portion 612. As shown in the embodiment of FIG. 6B, the housing 610 holds a pair of light components 632. Further, the top light component 632 can be mechanically detached from the interior of the housing 610, for example, using one or more latch mechanisms. The interior of the housing 610 can include an interface that electrically connects to the power connector of the top light component 632 when the light component is fully inserted into the housing. The interface of the light component 632 can be connected to, for example, the power bus of the motorcycle 100.

[0066] In an embodiment, one or both of the light components 630, 632 include a battery that can be charged using power from the battery module 410 (or other power source connected to the power bus). Further, in an embodiment, the top light component 632 can be unlatched or released from the housing 610 (utilizing an internal rechargeable battery) to operate as a portable and independent light component.

[0067] In some variations, the battery of the light component 632 can also be used to charge other devices. Thus, the light component 632 can include one or more electrical ports to receive a charging cable. Further, the light component 632 can power other auxiliary components such as a music player or a radio.

[0068] FIG. 7 shows a cable feature for use in a handlebar assembly 140 according to one or more embodiments. The handlebar assembly 140 can include a section 714 provided with an opening for receiving a cable 710. The cable 710 can be retracted from and extended from the section 714. When extended, the cable can be wrapped around the user's helmet and around (e.g., through an opening formed in the helmet) or used to hold other items. The endpoint of the cable 710 can be inserted into a lock receptacle that can be integrated with the handlebar assembly.

[0070] In at least one alternative embodiment, FIG. 9 shows a removable battery housing 900 that holds a battery module such as battery module 410 described herein. The battery housing 900 can be manufactured through the processes as described in FIGS. 2A and 2B. Thus, the dimensions and other attributes of the frame can be determined based on, for example, the size of the battery module 410 held within the battery housing 900. The battery housing 900 can be formed from one or more sheets of sheet metal that are cut, bent, and folded according to a predetermined design. Rivet holes can also be formed simultaneously in regions where the sheets overlap. Thereafter, an adhesive can be applied to those regions of the individual plates, and the plates can be overlapped along those regions according to the plate pattern of the battery frame design. The plates are adhered to each other along the overlapped regions, and the holes in each plate are aligned to receive corresponding rivets. The rivets can be inserted mechanically, and the adhesive can be allowed to fully cure.

[0071] The battery module 410 can be housed within the battery housing 900. The battery module 410 can be inserted into and electrically connected to the wires of a power bus that powers the components of the motorcycle 1100. In particular, the battery module 410 can power the electric motor, lights, and auxiliary components of the motorcycle 1100. Further, inside the battery frame 142, a recharge circuit and a receptacle for receiving an input power source can be provided. For example, in some embodiments, the battery housing 900 can house a custom battery and include one or more skid plates 902 and wheels 904. The battery can be, for example, a 4.3 kWh lithium-ion battery that supplies 84V when fully charged. The battery module can perform approximately 1,200 charge cycles before the battery degrades to 80% of its capacity when fully charged. The skid plate 902 is provided on the underside of the motorcycle and may protect the battery module within the housing during operation of the motorcycle. The skid plate may be made of hard anodized aluminum. A bottom view of the battery housing 900 and the skid plate 902 is shown in FIG. 11G. The wheel 904 may be an omni-wheel that allows the battery housing removed from the motorcycle to be easily transported in any direction. The battery housing 900 can be removed from the electric motorcycle by unlocking the over-center latch at the top of the battery. Further, the lock of the secondary safety latch can also be released. When the lock is released, the battery housing rotates downward and can be completely removed after disconnecting the cable. At that time, the battery housing may be lowered from the bracket to the ground. The battery housing can include a side handle 906.

[0072] The battery housing 900 can include an integrated charger or a fast charger. The battery module may be charged while mounted on the motorcycle or removed and charged separately. A 110V power supply or a 220V power supply can be used. Further, or alternatively, a built-in charger may be provided in the battery itself. For example, the built-in charger may be a 3.3kW charger built into the battery module. In this example, only a charging cord is required.

[0073] Figure 10 shows a head tube component 1002. The head tube component 1002 may be similar to, for example, the head tube component 290 of FIG. 2D. As shown in FIG. 10, the head tube component 1002 includes a body 1004 having a top end portion 1006 and a bottom end portion 1008. The head tube component 1002 is fixed to the frame of the electric motorbike by a color assembly 1010 as shown. In this way, the head tube component 1002 can be assembled and attached to each frame assembly. Further, in some embodiments, the head tube component 1002 can be removably removed from the frame assembly of the motorbike 100 by applying a mechanical force (e.g., torque to the color 298 and the top end portion 294). The head tube component may be a removable head tube. One or more clamps may be provided to fix the head tube in a predetermined position to prevent movement of the head tube. Further, a flat plate for taking up slack and tightening may be provided between the color and the frame. The flat plate enables the use of a modular front end that is firmly fixed without the need for welding. In some embodiments, the head tube assembly is composed of two top retainer rings together with a squash plate having a tapered flange and two bottom retainer rings. This prevents movement between the front end and the frame and enables the head tube to be mechanically fixed instead of welding. In addition, this enables the front end to be replaced without replacing the entire frame.

[0074] Figures 11A - 11G show alternative embodiments of the electric motorbike 1100. The electric motorbike 1100 is in a similar range as the electric motorbike 100, but the electric motorbike 1100 includes modifications and variations of the electric motorbike 100.

A belt is connected between the electric motor, the swing arm, and the rear wheel. The belt is stretched tightly without slack so that the entire unit rotates together. In the first embodiment, the electric motorbike includes a removable battery and a battery housing. The battery housing is composed of a bendable metal material (e.g., stainless steel) and may be reinforced to protect the battery module within the housing. In some embodiments, the battery housing can include wheels for easily transporting the housing when removed from the electric motorbike. Further, the battery housing may be reinforced with one or more skid plates to protect the battery module during operation of the electric motorbike. The battery housing and the module can include an integrated charging system. Additionally or alternatively, the housing can include one or more sensors that provide measurements of the battery, such as battery life, current charge level, battery usage, temperature, etc.

[0077] Following the first embodiment, a seat adjustment operation system for an electric motorbike is provided. The seat adjustment operation system can include a push-button operation via the handlebar of the electric motorbike, etc. The rider of the motorbike can operate the button to move the seat of the motorbike up and down while sitting on the motorbike.

Exemplary computing systems include, but are not limited to, device control (e.g., light assembly, seat activation), display control (e.g., user interface providing readouts of sensor measurements), and passive entry security systems (e.g., key fob for starting / stopping the bike, motor to prevent the bike from tipping over or being stolen).

[0079] The disclosed electric motorbike may include a plurality of computer devices communicatively coupled to each other for the operation of the motorbike. Exemplary computer devices include, but are not limited to, a computing device having a display and a display controller, a motor controller, a battery controller, and a passive entry security system.

[0080] In some embodiments, the electric motorbike can be provided with a regenerative braking system. The electric motorbike can include a regenerative current of up to 74 amperes. The amount of regeneration available by default may be predefined. When the electric motorbike is in a first mode such as a sports mode, regeneration is not linked to the throttle. When the throttle is not being operated, regeneration does not operate. In this mode, the regeneration button on the motorbike's handlebar is activated. When the electric motorbike is in a second mode such as an eco mode, regeneration can be linked to the throttle, and regeneration operates when the throttle is not being operated. In this mode, the regeneration button does not activate. In either mode, regeneration can be activated by operating the mechanical brake using the right brake lever or foot brake. In the first mode, using the regeneration button and the mechanical brake together does not result in an additive effect.
