Multi-functional scooter and cargo hold

Abstract

Two independent wheeled cargo accessories are combined to add versatility and unusual cargo capability to bicycles and to a unique foldable scooter. Both accessories are useful independently of these vehicles. For easy portability, the scooter reconfigures without tools to be rolled on its wheels in its folded state. A strut adjuster enables quick re-positioning of the scooter's optional seat. In some embodiments, two auxiliary wheels are deployable in multiple positions, converting the accessories into a cart that carries both the folded scooter and other cargo, thus enabling the user to walk, shop, and carry goods in a retail setting.

[0005] The drawings provided herewith illustrate, among other things, examples of certain aspects of particular embodiments. Other embodiments may differ. Various embodiments may include aspects shown in the drawings, described in the specification (including the claims), known in the art, or a combination thereof, as examples. Other drawings are included in the provisional patent application that is incorporated by reference herein.Detailed Description of Examples of Embodiments

[0006] This provisional patent application describes, among other things, examples of certain embodiments, and certain aspects thereof. Other embodiments may differ from the particular examples described in detail herein. Various embodiments are or include: scooters, for example, that are ridden by people (e.g., for personal transportation), devices, apparatuses, machines, methods, or a combination thereof, for example, concerning or relating to such scooters. In various embodiments, for example, a scooter is human powered, for instance, being propelled by the rider, for instance, by pushing off the ground with a foot. In a number of embodiments, however, the scooter is electrically powered (e.g., instead or in addition to being human powered), for example, with an (e.g., onboard) battery, electric motor (e.g.,ECM), and controller. In various embodiments, for instance, the battery is rechargeable. Various embodiments are unique, modular, versatile, portable, adaptable, or a combination thereof, as examples. Further, in a number of embodiments, the frame of the scooter includes interchangeable parts that can be optionally combined in multiple different useful configurations. Many embodiments can optionally be electrically powered, manually propelled by the rider, or both.

[0007] Some embodiments have a foldable frame (e.g., fully foldable) designed to facilitate multi-modal (or multimodal) travel. Some embodiments fit into passenger vehicles or fold small enough to be brought onto trains, buses, and ferries, as well as yachts and larger cruise ships, as examples. Further, certain embodiments pack into luggage (e.g., ordinary luggage that can be brought onto commercial flights), for instance. In a number of embodiments, the scooter’s electrical system is powered by batteries, for example, which, in some embodiments, have been specifically designed for this purpose. Some embodiments are accepted by common air carriers, for example, as passenger luggage, for instance, as carry-on or “cabin baggage” or as checked bags, as examples.

[0008] The figures include drawings and photographs showing components and assembly of several configurations. Additional configurations are beyond those shown. Two different three-wheeled configurations are shown in several figures. Other embodiments have two wheels. Various embodiments are shown. Different embodiments may be functionally the same or similar, or may have differences that may be illustrated. Certain embodiments include, for example, tandem (e.g. , rear) wheels, which may be smaller than the front wheel in particular embodiments. Certain embodiments use wireless electric skateboard wheels, drive systems, or other parts, as examples.

[0009] Various embodiments allow the user to roll the folded scooter on its wheels when in its folded position, for instance, so there is often no need to carry it. The figures show that in some embodiments, for example, the user folds the frame, rotates the handlebars (e.g., 90 degrees from the deployed position), and then tips the folded scooter back a bit, to push it along upon its wheels, for example, like a wheelbarrow.

[0010] Further, some embodiments, include a configuration that provides for stowing the seat (e.g., when the rider wants to ride standing up), for example, that may be less expensive thanother alternatives. In particular embodiments, for example, instead of folding the seat post, the user removes it from a receiver tube and stows it, for example, underneath, or alternatively above, the rear cargo rack.

[0011] Certain embodiments include a seat post that can be pitch-adjusted, for example, without using tools. The figures include an exploded view of an example of this mechanism. Further, some embodiments include two hinges (e.g, within the frame). Even further, certain embodiments include a solar collector, for example, a canopy, for instance, that charges onboard batteries which power an electric version of the scooter. In various embodiments, one or more solar panels power the scooter while riding, charge the batteries while the scooter is parked, or both.

[0012] In various configurations, the scooter includes a seat accessory, for example, which may be adjustable in pitch (z.e., fore-aft), height, or both, for instance, by riders of different statures. This is illustrated for multiple embodiments. Various embodiments are functionally the same or similar. Particular embodiments, for example, include a strut adjuster, which: may be continuously adjustable; may not require tools for adjustment; may be similar to a turnbuckle; may facilitate quick adjustability of the scooter seat position; may control and restrain the position of a pitch-adjustable seat; or a combination thereof, as examples. Other embodiments include, for instance, a pitch-adjustable seat position that is adjustable into several discrete positions, for example, by use of a simple tool such as an Allen key, for instance, that is commonly used by cyclists.

[0013] Some configurations include a foldable frame, but in other configurations, the frame is not foldable (z.e., rigid). Further, different configurations (e.g, foldable or rigid) have either two or three wheels, for example. Still further, different configurations (e.g. , foldable or rigid) have different size (e.g., diameter) wheels, and some configurations have different size front wheels than rear wheels. In particular embodiments, for example, the front wheel is smaller in diameter, width, or both, when compared to the rear wheel or wheels. In other embodiments, however, the front wheel is larger in diameter, width, or both, when compared to the rear wheel or wheels. In some embodiments with two wheels, for instance, the front wheel has a larger diameter than the rear wheel. For instance, in particular embodiments, the front wheel has a 15-inch diameter and the rear wheel has a 12-inch diameter. In other embodiments, the frontand rear wheels are the same diameter, for instance, 12 or 15 inches. Some three-wheeled embodiments have two wheels in the front. Other three- wheeled embodiments have one wheel in the front and two wheels in the rear.

[0014] Further, in some embodiments having three wheels, the two wheels tilt when the scooter is turned, for example, a “tilting trike”. Further, in certain embodiments with three wheels, the two wheels that are on the same end of the scooter are smaller than the single wheel on the opposite end of the scooter. In particular embodiments, for example, the front wheels each have an 11 inch diameter and the rear wheel has a 12- or 15-inch diameter, as examples. Different embodiments can either be electric (e.g, 15-inch powered rear wheel) or manual (e.g., 12-inch rear wheel).

[0015] In some embodiments, the scooter includes a frame, for example, that is foldable, for instance, without use of tools. In a number of embodiments, folding the frame automatically elevates the frame away from the ground during folding, for example, so that the folded assembly transitions to a compact, easily-transported state, for instance, in which the wheels are parallel or nearly parallel. Further, in a number of embodiments, the wheels remain on the ground when the scooter is in the folded position, and the frame is not at risk of damage due to contact with the ground while the user pushes, for instance, the folded scooter on its wheels. As a result, the user is not obliged to carry the folded assembly in order to transport it.

[0016] Even further, in some embodiments, the user is able to utilize the folded assembly for porting cargo loads, for example, that are mounted on the assembly as the folded assembly is on the ground on its wheels. The “ground”, as used herein, may be the surface of a street or sidewalk, as examples.

[0017] Various embodiments include (e.g., one or more) folding joints, such as hinges or pivots (e.g., pivot points), for example, positioned or oriented within the frame in a manner that causes the frame to automatically move upwardly (e.g., away from the ground), while the joints are being actuated for collapsing the frame to its folded or minimized state. In some embodiments, for example, one or more of the joints may be positioned within the assembly such that their axis of rotation occurs at an angle less than 90 degrees perpendicular to the ground or deck, for instance, so that the deck or the entire assembly is automatically elevated away from the ground as the user collapses or folds the assembly. In a number of embodiments,as the assembly is moved into its folded position, the elevation of the frame occurs due to the rotation of the hinging or pivoting joints about an axis which is tilted (e.g., relative to horizontal). Further, while the assembly is in motion across the ground, in various embodiments, the wheels are at all times (e.g. , normally or preferably) the only point of contact between the ground and the assembly. In some embodiments, as the joints are pivoted or rotated, elevation of the deck or frame occurs, for instance, due to change in axial distance between the deck and support points.

[0018] In a number of embodiments, a scooter includes a foldable scooter frame, for example, that can be deployed and folded without use of: tools, auxiliary wheels, or both. Further, in various embodiments, the scooter is usable for transportation of goods and cargo in both its fully deployed state and in its minimized, collapsed state. Still further, in some embodiments, the scooter has a modular design. Even further, in particular embodiments, the scooter includes interchangeable parts, for example, which can be assembled, disassembled, and reconfigured, for instance, by the user, for example, to create multiple configurations with different purposes, uses, or both. For example, one use is packing the assembly into luggage for commercial flights or other confined settings.

[0019] In a number of specific embodiments, for example, a foldable scooter includes a first wheel, a second wheel, and a frame, for instance, having at least one pivot point. Further, certain embodiments also include a third wheel. Still further, in various embodiments, the scooter is folded by rotation about the pivot point (z.e., on the frame), for example. Further still, in a number of embodiments, the scooter is configured to be ridden (e.g, on ground) by a user when the scooter is not folded, and when the scooter is ridden, the scooter is supported (e.g., on the ground) by the first wheel and the second wheel. Even further, in some embodiments, when the scooter is folded, the scooter is configured to be rolled (e.g., on the ground) by the user, for instance, on the first wheel, on the second wheel, or both, for example, for transportation of the scooter (i.e., when it is not being ridden). Moreover, in particular embodiments, when the scooter is folded, the scooter is configured to be rolled (e.g., on the ground) by the user, for instance, on the first wheel, on the second wheel, and on the third wheel, for example, for transportation of the scooter (i.e., when it is not being ridden). Examples include tadpole trike and tandem rear wheel configurations, for instance.

[0020] Further, in a number of embodiments, a scooter includes a first wheel, a second wheel, a frame, and a seat, for example, that a user can sit on when riding the scooter. Further still, certain embodiments also include a third wheel. In various embodiments, for example, a seat column supports the seat (e.g., from the frame), a strut adjuster, for instance, extends from the frame (e.g., to the seat column), or a combination thereof. In other embodiments, as another example, the strut adjuster extends to the seat. Still further, in a number of embodiments, the strut adjuster is configured to be adjusted by the user, for example, to adjust fore and aft position of the seat.

[0021] In some embodiments, for example, the strut adjuster is adjusted by altering the length the strut adjuster. Further, in some embodiments, the seat column is (e.g., also) adjustable, for example, to adjust the seat in a vertical direction. Further still, in particular embodiments, the seat column is a telescoping seat tube, for instance, configured to be adjusted by the user to adjust height of the seat. Still further, in various embodiments, the seat column pivots, for instance, where the seat column connects to the frame. Even further, in some embodiments, the strut adjuster pivots, for example, where the strut adjuster connects to the frame, where the strut adjuster connects to the seat column, or both. Such pivoting (e.g. , of the seat column, strut adjuster, or both) may allow for adjustment of the seat, for example: in the fore and aft direction, with the strut adjuster, or both. Even further, in particular embodiments, the strut adjuster includes a central member or a member that the user rotates, for example, to adjust fore and aft position of the seat. In particular embodiments, the user does not need to rotate the central member, but rather, unlocks the central member and then moves the seat, and the central member rotates on its own as the user moves the seat. The user then locks the central member to maintain the desired seat position. Moreover, in certain embodiments, the strut adjuster is or includes a turnbuckle. Furthermore, in particular embodiments, the (e.g., central) member has right-handed threads, left handed threads, or both, for example, used to adjust length of the strut adjuster. Even further still, in certain embodiments, the strut adjuster is located on the scooter behind the seat or behind the seat column, for example, between the seat and the rear wheel(s) or between the seat column and the rear wheel(s). Further, in various embodiments, the strut adjuster includes an adjustment locking mechanism (e.g, that locks to prevent adjustment of the strut adjuster, for instance, while the scooter is being ridden).

[0022] Further still, in some embodiments, the scooter includes a deck, and the user can stand on the deck when riding the scooter. Still further, in particular embodiments, when the scooter is being folded (i.e., from the not-folded position to the folded position, e.g., while the first wheel and the second wheel are on the ground, and in particular embodiments, the third wheel as well), the deck moves upwardly, for example, away from the ground. Even further, in certain embodiments, the pivot point is at an angle of less than 90 degrees from the deck. Even further still, in particular embodiments, the pivot point is at an angle of less than 90 degrees from the ground (i.e., when the scooter is not folded and the scooter is resting on the ground, for instance, on the first wheel, on the second wheel, and in some embodiments, the third wheel). Moreover, in some embodiments, the pivot point includes a hinge, a (e.g. , pivot point) locking mechanism (e.g., that locks to prevent rotation around the pivot point, for instance, while the scooter is being ridden), or both. In particular embodiments, for example, the (e.g. , pivot point) locking mechanism locks to prevent rotation around the pivot point when the scooter is folded. Moreover, in various embodiments, when the scooter is being folded (i.e., from the not-folded position to the folded position, e.g., while the first wheel and the second wheel, and in particular embodiments, the third wheel, are on the ground), the frame moves upwardly, for instance, away from the ground. In a number of embodiments, the pivot point or hinge includes a pin or axis, for example, that is nearly vertical (e.g., when the scooter is not folded and is resting on its wheels on horizontal ground). In some embodiments, for example, the pivot point, pin, or axis is at an angle of 60 to 89 degrees, 70 to 89 degrees, 75 to 89 degrees, 75 to 85 degrees, 77 to 83 degrees, 78 to 82 degrees, 75 to 80 degrees, 80 to 85 degrees, substantially 80 degrees, or 80 degrees, as examples, when measured from horizontal, the ground, the deck, or a combination thereof, as examples.

[0023] In various embodiments, the folded scooter is prevented from unfolding itself, for example, by a locking mechanism. Certain embodiments, for instance, include one or more latches. Examples are shown in some of the drawings. The tilting trike frame, for instance, has a front pivot that latches internally. Other embodiments have plunger-pin latches, for example, separate from the pivots or hinges, for instance, which temporarily conjoin the folded front fork to the deck, temporarily conjoin the folded rear fork to the deck, or both. An example of a rear fork latch is shown, exploded, in Figure 3. Various embodiments include front and rear latches. Figures show examples of both a front fork latch and a rear fork latch.

[0024] In various embodiments, the scooter is configured to be folded and unfolded without using tools. As used herein, “configured” means designed specifically for the act described (e.g. , in this case, “folded and unfolded without using tools “) in normal operation (e.g. , by the user). Further, in some embodiments, the scooter includes a basket, for example, configured for transportation of cargo, for instance, when the scooter is being ridden. For example, the cargo may be a typical bag of groceries in a number of embodiments. In particular embodiments, the scooter is (e.g., also) configured so the (e.g., basket) can be used for transportation of the cargo when the scooter is folded, for example, and being rolled (e.g., on the ground) by the user, for instance, on the first wheel and on the second wheel. Further still, in a number of embodiments, when the scooter is folded, the first wheel is substantially parallel to the second wheel. As used herein, “substantially parallel” means parallel to within 15 degrees. Even further, in various embodiments, when the scooter is folded, the first wheel can be positioned or locked to be substantially parallel to the second wheel, or the scooter is configured so that the steering can be locked into a position so the first wheel is substantially parallel to the second wheel, or both.

[0025] In a number of embodiments, when the scooter is folded, or (alternatively) disassembled, the scooter will fit into a suitcase, for example, that is small enough to be taken on a commercial airline flight. This may include folding at more than one pivot point, for example. See, for instance, the drawings. Further, in particular embodiments, when the scooter is folded, the scooter will fit into luggage, for example, carry-on size luggage, for example, on a commercial airline flight, or non-carry-on size luggage, as another example. Still further, in some embodiments, the scooter is electrically powered. Even further, in particular embodiments, for example, the scooter includes an electric motor e.g., that drives the first wheel), a battery (e.g., that powers the electric motor), a controller (e.g., that controls the electric motor), or a combination (e.g., all) thereof. Moreover, certain embodiments include multiple electric motors (e.g., that drive one or more wheels). Even further, in some embodiments, the first wheel is a rear wheel of the scooter. Further still, in some embodiments, the second wheel is a front wheel of the scooter. Even further still, in certain embodiments, the first wheel and the second wheel have unequal diameters. Examples are shown on the drawings, described herein, or both.

[0026] Moreover, in particular embodiments, the scooter (e.g, further) includes a third wheel. Further, in various such embodiments, when the scooter is being ridden, the scooter is supported (e.g., on the ground) by the first wheel, the second wheel, and the third wheel. Still further, in certain embodiments, the third wheel is a front wheel of the scooter. In other embodiments, however, the third wheel is a rear wheel of the scooter. Even further, in particular embodiments, the third wheel and the second wheel of the scooter tilt, for example, when the scooter turns a corner, for instance, in certain embodiments where the third wheel and the second wheel are front wheels of the scooter. Further still, in particular embodiments, the first wheel and the third wheel are tandem (e.g., rear) wheels of the scooter. Even further still, in some embodiments, the first wheel and the third wheel, as examples, have a common diameter, are each smaller in diameter than the second wheel, or both. Moreover, in some embodiments, the first wheel and the third wheel each include an electric motor. For instance, in particular embodiments, the scooter includes a first electric motor that drives the first wheel and a second electric motor that drives the third wheel. Some embodiments further include a battery, for example, that powers the first electric motor and the second electric motor, a controller, for instance, that controls the first electric motor and the second electric motor, or both.

[0027] Various embodiments provide for rolling the scooter on three wheels. In particular embodiments, for instance, this can be done in both the tandem wheels configuration and also the trike configuration. In some embodiments, a trike can be transformed from its deployed state to a stowed position wherein it can be rolled on three wheels, for example, in its fully minimized state. In some embodiments, after the trike wheels have been relocated from deployed (riding) position, the handlebar post is folded (stowed) as well, for example, creating a very compact configuration that may be stashed underneath a desk, for instance. Further, some embodiments include parts and mechanisms that allow the user to transform the trike from a rideable, deployed state into the folded state that can be rolled on the ground for easy transport. In certain embodiments, for example, the user accomplishes this transformation without the use of tools. In particular embodiments, for instance, The two front (e.g., 11 -inch diameter) trike wheels have pushbutton quick-release axles. An example is a type already in use on wheelchairs. In some embodiments, the axles are installed on the trike. In certain embodiments, the user pushes a spring-loaded pushbutton on the (outboard) end of each axleto release the axle from the trike assembly and remove the wheel from the assembly. In particular embodiments, the user then relocates (e.g., both) of the two front trike wheels to their stowed position, for instance, using the same pushbutton axles to install them in their stowed orientation.

[0028] In various embodiments, the scooter further includes handlebars, for example, that rotate to steer (e.g., at least) one (e.g., the second) wheel. Moreover, in a number of embodiments, the scooter further includes at least one brake, for example, that the user applies to slow rotation of at least one (e.g., the second) wheel. An example is a hydraulically- or cable-operated disc brake, for example, operated by a hand lever on the handlebars.

[0029] Various embodiments of (e.g., electric) scooter models (e.g., frames thereof) are convertible (e.g., to or from) various cargo-carrying styles. An example has a long wheelbase with a long cargo box, for example, with a load capacity of approximately 150 pounds of cargo, 6 (or more) standard grocery bags, or both. Further, “approximately”, as used herein, means to within plus or minus 25 percent. Another example has a shorter wheelbase with short cargo box, for instance, with a load capacity of approximately 100 pounds of cargo, 4-5 standard grocery bags, or both. Further, yet another example has a short frame ("Generation 5") with an (e.g., optional) cargo basket, but with no cargo box, for instance, foldable to the smallest (minimum) collapsed size.

[0030] In a number of embodiments, the cargo scooter converts, or is convertible, for example, without tools, to and / or from: a deployed state, for example, rideable with or without cargo, and a semi-stowed state, for instance, converted into a cart (e.g., a shopping cart). In this context, a cart is pushed or pulled by the user while the user walks on the ground whereas a scooter is usually (or is configured to be) ridden by the user. In various embodiments, the ability to be converted into a cart reduces or eliminates or minimizes risk of theft, for example, since there is no need to leave the scooter unattended (e.g., locked up in public areas), for instance, while the user is in a retail environment. Rather, in various embodiments, the minimized or stowed scooter can be conveniently wheeled indoors and brought into many retail settings.

[0031] Further, in various cargo scooter configurations, in the fully deployed or rideable state, the scooter may have (e.g., two) auxiliary wheels, for instance, approximately 4-inchdiameter wheels, or in some embodiments, rescue wheels. In various embodiments, auxiliary wheels have multiple functions, can be stowed and deployed without use of tools, or both, as examples. Still further, in particular embodiments, the auxiliary wheels have three functional positions, for example. In some embodiments, for example, in a deployed position, rescue wheels assist the rider in case of loss of balance, for instance, during riding, for example, by preventing the edges or comers of the cargo box from contacting or dragging on the ground. Even further, rescue wheels may (e.g., momentarily) support the cargo box when the scooter is tilted or banked, for instance, while traveling across a steeply inclined or declined roadway. Further still, in various embodiments, in a stowed position, rescue wheels will not contact the ground during riding. Even further still, in certain embodiments, the rescue function is available to be deployed, for example, without use of tools. Moreover, various embodiments include a cart mode in which auxiliary or rescue wheels are deployed (e.g., latched) into their lowest position, for example, while in contact with the ground, for instance, to permit quick and simple conversion of the scooter from its rideable state into a (e.g., shopping) cart.

[0032] Different embodiments of cargo scooters can utilize different styles of cargo boxes. In particular embodiments, the cargo box accepts and stow the rear half or part of the deployed cargo scooter, for example, which, in some embodiments, is folded or detached (or both) from the front half or part of the cargo scooter in various models. In certain embodiments, this transforms the deployed scooter from its rideable state into its cart mode, for example, so that the user can (e.g., comfortably and conveniently) keep the complete scooter with them, for example, while in a retail environment.

[0033] Various embodiments include various cargo box configurations. Examples include rigid box designs. One example is a short rigid cargo box, for example, with an (e.g., optional) hinged cover. In particular embodiments, this cargo box requires tools for disassembly and removal from the scooter frame, for example, for storage and shipping. Certain embodiments include a load capacity of approximately 100 pounds of cargo, 4 - 5 standard grocery bags, or both. Another example is a long rigid cargo box, for instance, with an (e.g., optional) solar panel cover. Again, in particular embodiments, this cargo box requires tools for disassembly and removal from the scooter frame, for example, for storage and shipping. Certain embodiments have a load capacity of approximately 150 pounds of cargo, 6 or more standard grocery bags, or both. Other embodiments include foldable box designs. Some embodimentshave removable side panels, for example, not requiring use of tools. Further, in certain embodiments, removing one side panel facilitates stowing the folded rear end or part of the cargo scooter inside the cargo box. Still further, in particular embodiments, removing 2 side panels facilitates full collapse of the cargo box to a flat folded state, which, in some embodiments, is also completely removable from the scooter frame, for instance, without use of tools. Even further, an additional style of foldable cargo box has a removable rear panel, for instance, which stows and deploys without the use of tools. In particular embodiments, for example, this cargo box also folds to a flat state, but in certain embodiments, requires use of tools to be removed from the scooter frame.

[0034] In a number of embodiments of a cargo scooter, or a non-cargo scooter, the scooter includes a suspended seatpost, for example, which is quick-adjustable, continuously adjustable, or both, for instance, by the user, for example, without requiring use of tools. Further, in various embodiments, adjustability of the seatpost pitch, of the seat height, or both, is continuous. Still further, in various embodiments, the scooter can be disassembled, for instance, for storage and / or shipping, and in particular embodiments, can pack into a suitcase or box. In some embodiments, cargo scooter models pack into larger narrow and / or flat-pack boxes, for example, optimal for shipping. In various embodiments, a solar panel charges the scooter the batteries while the scooter is parked in the sun, while riding, or both.

[0035] In some embodiments, the scooter includes a cargo box, the scooter includes (e.g., two) auxiliary wheels, or both. For example, in particular embodiments, the auxiliary wheels each have multiple functions, can be stowed and deployed into three functional positions, or a combination thereof. Further, in some embodiments, the auxiliary wheels can e.g., each) be deployed into a position as rescue wheels, for example, that assist the rider in case of loss of balance, for instance, while riding the scooter. Still further, in various embodiments, the auxiliary wheels can (e.g., each) be deployed into a position in which the auxiliary wheels contact the ground, for example, and the scooter is configured to be used as a (e.g., shopping) cart. Moreover, in various embodiments, the scooter converts, is convertible, or is configured to convert, between a deployed state (e.g., that is rideable), and a semi-stowed state (e.g., in which the scooter is useable as a shopping cart, for instance, in a retail environment). Even further, in some embodiments, the scooter converts without tools between the deployed stateand the semi-stowed state. Even further still, in certain embodiments, the scooter is configured to carry cargo in the deployed state, the semi-stowed state, or both.

[0036] Various examples of embodiments include a scooter comprising a first wheel, a second wheel, and a frame. Further, in some such embodiments, the scooter further includes (e.g., two) auxiliary wheels, for instance, that each have multiple functions, that can each be stowed and deployed into various (e.g., three) functional positions, or both. Further still, in some embodiments, the auxiliary wheels can each be deployed into a position as rescue wheels, for example, that assist the rider in case of loss of balance, for instance, while riding. In particular embodiments, the auxiliary wheels can be deployed to contact the ground in which the scooter is configured to be used as a (e.g., shopping) cart. Even further, in various embodiments, the scooter converts, or is convertible, between a deployed state that is rideable; and a semi-stowed state in which the scooter is useable as a (e.g., shopping) cart, for example, in a retail environment. Even further still, another example is a scooter having a first wheel, a second wheel, a frame, and a cargo box, wherein the cargo box accepts and stows a rear part of the scooter, for example, which is folded and detached from a front part of the scooter, for instance, to transform the scooter from a deployed rideable state into a configuration to be used as a shopping cart, for example, so that a user can keep the scooter with the user while in a retail environment.

[0037] In certain embodiments, the cargo box has a load capacity, for example, of approximately 150 pounds of cargo. Further, in particular embodiments, the cargo box has a load capacity of at least 6 standard grocery bags or of approximately 6 standard grocery bags, as examples. In other embodiments, the cargo box has a load capacity of approximately 100 pounds of cargo, at least 4 standard grocery bags, approximately 4 standard grocery bags, approximately 5 standard grocery bags, or a combination thereof. Further still, in particular embodiments, the scooter has a cargo basket. Even further still, in certain embodiments, the cargo basket is foldable, for example, into a collapsed position. Moreover, in some embodiments, the scooter is modular. Further still, in particular embodiments, certain major assemblies of the scooter can be replaced to obtain a scooter with different characteristics.

[0038] In particular embodiments, the auxiliary wheels each have a diameter of approximately 4 inches. Further, in some embodiments, the auxiliary wheels can be stowedand deployed, for example, without the use of tools. Still further, in certain embodiments, the auxiliary wheels can each be deployed (e.g. , into a position) to prevent edges or comers of the cargo box, for example, from contacting, or dragging on, the ground. Even further, in particular embodiments, the auxiliary wheels (e.g., momentarily) support the cargo box, for example, when the scooter is tilted or banked, while traveling across a steeply inclined or declined roadway, or a combination thereof, for example. In various embodiments, however, the auxiliary wheels can (e.g. , each) be deployed into a position in which the auxiliary wheels will not contact the ground during riding. Even further still, in some embodiments, the cargo box accepts, stows, or both, a rear part of the scooter, for example, which is folded, detached, or both, from a front part of the scooter, for instance, to transform the scooter from a deployed or rideable state (or both), for example, into a configuration to be used as a (e.g., shopping) cart, for instance, so that a user can (e.g., comfortably, conveniently, or both) keep the scooter with the user, for example, while in a retail environment.

[0039] Particular embodiments include wireless controls, for example, wireless speed control. Certain embodiments, for example, include a custom-designed local wireless network, for instance, that is onboard the scooter. Further, various embodiments provide for, and permit, the rider (e.g., exclusively) to control speed, for example, with a throttle, an electronic (e.g, rear) brake, or both. In particular embodiments, hardware includes an electronic circuit board or transmitter, for example, mounted on the (e.g., right) handlebar, for instance, that is wired to a twist throttle, that the rider can rotate (e.g., 60 degrees of circumference) about the handlebar, for example, like on a motorcycle. Still further, various embodiments include a brake lever that has an on-off sensor in it, for instance, wired to the transmitter. Even further, in a number of embodiments, the signal transmits wirelessly to a further circuit or receiver, for example, that is mounted proximate the rear wheel. In certain embodiments shown, for example, the receiver is mounted on a tall, triangular-shaped transparent plastic support underneath the rear rack that the battery is sitting on top of, over the rear wheel. Even further still, in various embodiments, the receiver is wired to the motor controller (e.g., which may be enclosed under the battery). This is an example of how the rider can signal and accelerate the motor. Further still, in particular embodiments, the brake signal is (e.g., also) wirelessly transmitted, for instance, in this same manner.

[0040] Still further, in a number of embodiments, the scooter includes a custom or customizable (e.g., suspended) seatpost. Even further, some embodiments include tool-free or quick-adjustable (or both) seat height adjustability. Various embodiments provide a unique combination to bicycles and scooters. Particular embodiments include, for example, quick height adjustability together with suspension of the seat, for instance, for a more comfortable ride. Even further still, some embodiments are adjusted by pulling or pushing on a lever that actuates a gas spring, for example, similar to actuation of existing height-adjustable office chairs. Certain embodiments, however, combine this (e.g., in a single assembly) together with custom (and / or customizable) seatpost suspension to increase ride comfort. Further still, some embodiments include a height-adjustable handlebar. The figures show some examples.

[0041] A number of embodiments include (e.g., tool-free) quick deployment and conversion to cart mode. In particular embodiments of cargo scooter models, for example, the rear part or half of the scooter folds and detaches from the front (e.g., cargo) end of the scooter, for instance, without requiring tools. Further, some embodiments provide for quick conversion, for example, from a deployed or rideable state to a stowed or semi-stowed position. Still further, various embodiments provide emphasis on ability to quick-deploy and quick-stow, to and from cart mode. Even further, in a number of embodiments, this makes the scooter multifunctional. Moreover, various embodiments quick-detach and re-attach, for example, to make the multiple functions of the scooter practical and convenient for use by the user. In some embodiments, a cargo scooter design or frame, for example, has (e.g., interchangeable) parts that can (e.g., also) be used with an (e.g., existing) e-bike. In particular embodiments for example, the front half of the cargo frame has two separable pieces. In certain embodiments, for example, one of these pieces is taller at the front, near the front wheel, and certain embodiments use that for the cargo e-bike (e.g., but not for the cargo scooter). Other embodiments may differ.

[0042] Various embodiments include various different designs. One such design is a cargo scooter that has a removable cargo hold, for example, which may look like a rectangular bucket, at the front end. In some embodiments of this design, this bucket structure can be used both on the scooter and off of it, for instance, in particular embodiments, as both a shopping cart and a hand truck. Further, some embodiments include a linkage, for example, that conjoins a front-loaded cargo structure with an (e.g., existing, electric, or both) bicycle. In certainembodiments, this adds cargo capacity to a (e.g., very powerful electric) bike. The shopping cart feature is not available with all embodiments of this design, but the cargo bucket may be the same as on the cargo scooter, and it may be similarly removable from the cargo bicycle, and may be be used as a hand truck, as a shopping basket, or both in particular embodiments. Although this is not necessarily the same as a shopping cart, it may allow the user to use the cargo hold (bucket) in a retail setting, for example, for collecting groceries or other goods, because it can roll on its own (e.g., small) wheels. In some embodiments, this may be the same as or similar to a cargo hold that is removable from a cargo scooter. Even further, certain embodiments include “tandem drive” scooters, for example, which may be streamlined, have various suspension, or a combination thereof.

[0043] Captions on a number of the figures describe examples of embodiments which may be illustrated. Some embodiments include, for example, convertibility to and from "cart mode", for instance, via separation of the frame into 2 halves, and stowing the folded rear end, for example, in the cargo hold, for instance, to create the shopping cart. In certain embodiments, the cargo hold can be one of multiple styles, which may be removable from the cargo frame for use as a (e.g., small) platfom-style hand truck, as a shopping trolley, or both. Certain embodiments include, for example, four wheels attached (e.g., screwed) onto the bottom of the cargo hold. Further, some embodiments use telescoping handles, for example, similar to handles used on suitcases. In particular embodiments, the cargo hold can be installed and un-installed on the cargo frame (e.g., by the user), without tools, and this assembly itself can be conjoined together with the cargo scooter and, alternatively, in certain embodiments, with a (e.g., specific, high-torque, or both) electric bicycle (e.g., brand name "FLX"). Various embodiments have significant versatility in the cargo-carrying accessory. Further still, various designs are multifunctional and convertible into other useful tools. Examples include the hand truck and convertibility to hand truck and electric cargo bike. Different embodiments include, or can be used as: an electric cargo scooter, an electric cargo bicycle, a foldable electric commuter scooter, a foldable human-propelled exercise scooter, a shopping cart, and a hand truck.

[0044] An example of an embodiment is a (e.g., front-loading) cargo accessory that is usable and interchangeable on both a cargo scooter & a cargo bike. Further, certain embodiments include (e.g., various styles of) a multi-functional cargo-carrying accessory that isusable both on & off of a cargo scooter, a cargo bicycle, or both. Examples of multifunctionality include, in particular embodiments: a 3-wheeled shopping cart, a 4-wheeled shopping trolley, and a platform-style hand truck. Still further, some embodiments include a (e.g., improved, quick release, or both) mechanism for transforming between a scooter and a shopping cart, for example. Even further, various embodiments include a (e.g., quick-release, quick installed, or both) suspension seat post. Various (e.g., essential) mechanical parts are shown on the drawings. The drawing captions contain further information. Some embodiments include, for instance, a (e.g., removable) cam-actuated kingpin. In particular embodiments, for example, this fastens the cargo scooter front half (e.g., at the tow bar) to the cargo scooter rear half (e.g., at the tow hook that seats into the tow bar). Further still, in some embodiments, the kingpin allows the user to separate the cargo scooter (e.g., without use of tools) into two halves. In particular embodiments, for example, the rear half folds up and stows in the cargo hold area in the cart. In some embodiments, (e.g., of the tow bar & tow hook) a single kingpin is used, wherein, in other embodiments, two kingpins are used.

[0045] In certain embodiments, the cargo hold is removable (e.g., by the user, without tools, or both) from the scooter frame and is usable for transporting cargo separately from the scooter, for example, via wheels onto the bottom of the cargo hold. In particular embodiments, for instance, the bottom of the cargo hold includes two (e.g., small) caster wheels and two (e.g., small) fixed-direction wheels. In this example, these wheels transform the cargo hold into a (e.g., small) hand truck, which is usable as a (e.g., small) rollable platform, and, in some embodiments, also as a rollable crate. In such embodiment, the cargo hold is "convertible" between these two functions. Further, in some embodiments, the hand truck, crate, or both, are mountable on a frame that is conjoinable (e.g., at the user’s option) onto a cargo bicycle. In various embodiments, the cargo hold is "interchangeable", because it is mountable (e.g., by the user, without tools, or both) on both an electric cargo scooter and an electric bicycle. Still further, in particular embodiments, the scooter converts into a shopping cart, but the cargo bike assembly does not. In some embodiments, however, the cargo hold, hand truck, or platform truck (or a combination thereof) is usable on both the scooter and the bicycle. Even further, in some embodiments, the (e.g., convertible) cargo hold is an interchangeable accessory to both bike and scooter. In other embodiments, however, for instance, an illustrated 3 -wheeled cart, is not an interchangeable accessory to both bike and scooter.

[0046] In various embodiments, a scooter or bike accessory is a collapsible & convertible cargo hold. Further, in some embodiments, it holds 3 bags of groceries, folds up, or both, as examples. Still further, in particular embodiments, a single-kingpin joint is used on the scooter, the cargo hold is interchangeable with an electric bike and a cargo scooter, or both. Even further, in some embodiments, the cargo hold can be converted (e.g., by the user, without tools, or both) into a platform hand truck. Even further still, in certain embodiments, the scooter (e.g., the entire scooter excluding the hand truck) can be packed into a suitcase and ported on that hand truck, through an airport, for instance. Moreover, in particular embodiments, the scooter will disassemble sufficiently to be packed into a 24"x24"x44" suitcase, for instance. This is another way in which particular embodiments are convertible. Furthermore, in some embodiments, the cargo hold is configured (e.g., is big enough) to carry the (e.g., folded) rear half of the cargo scooter. Further still, in certain embodiments, the cargo hold is specifically designed to do that. In other embodiments, the cargo hold carries goods, but is not designed to carry the scooter or bike upon which it is installed and used. In particular embodiments, however, the cargo hold carries the vehicle (e.g., scooter), as well as the vehicle carrying the cargo accessory.

[0047] In a number of embodiments, a scooter includes a cargo hold, for example, that is configured to be used to carry cargo on the scooter. Certain examples are shown. Further, in some embodiments, the cargo hold is (e.g., also) configured to be disconnected from the scooter, connected to a bicycle, and used to carry cargo on the bicycle. The bicycle may be an e-bike, for example. Still further, various embodiments are or include such a cargo hold (e.g., that is so configured). Even further, in some embodiments, the cargo hold is (e.g., also) configured to be: disconnected from the scooter, pushed by the user in front of the user (e.g., when the user is walking), and used, for instance, as a shopping cart, for example, while the user is shopping in a store. Further still, in particular embodiments, the cargo hold or shopping cart rolls on three wheels while the user is shopping in the store. In certain embodiments, (e.g., smaller) rear wheels of the shopping cart are included, deploy, or both, for this purpose, for example.

[0048] In various embodiments, the scooter includes a front wheel. Further, in a number of embodiments, the front wheel of the scooter also serves as a front wheel of the shopping cart, for example, while the user is shopping in the store. Still further, in some embodiments, thefront wheel of the scooter also serves as a front wheel of the bicycle, for example, while the cargo hold is connected to the bicycle. Even further, in certain embodiments, the front wheel of the scooter replaces the (e.g., original) front wheel of the bicycle while the cargo hold is connected to the bicycle. Further still, in a number of embodiments, the cargo hold is mounted on the bicycle in front of the user when the cargo hold is connected to the bicycle and the user is riding the bicycle. Even further still, in some embodiments, the cargo hold is mounted on the bicycle in front of handlebars of the bicycle when the cargo hold is connected to the bicycle. Moreover, in various embodiments, the cargo hold is mounted on the bicycle behind the front wheel of the scooter when the cargo hold is connected to the bicycle. Furthermore, in particular embodiments, the front wheel of the scooter is turned by the user by turning handlebars of the bicycle while the cargo hold is connected to the bicycle (e.g., when the front wheel of the scooter is serving as the front wheel of the bicycle).

[0049] In a number of embodiments of a cargo hold that is configured to be used to carry cargo on a scooter, the cargo hold is also configured to be disconnected from the scooter, pushed by the user (e.g., in front of the user, for example, when the user is walking), and used as a shopping cart, for example, while the user is shopping in a store. Further, in various embodiments, the cargo hold is mounted on the scooter in front of the user when the user is riding on the scooter. Even further, in some embodiments, the cargo hold is configured to carry the scooter (e.g., excluding the cargo hold) when the cargo hold is being pushed by the user (e.g., in front of the user, when the user is walking, or both). Still further, in particular embodiments, the cargo hold includes (e.g., four) cargo hold wheels and the cargo hold is configured to be disconnected from the scooter and pushed or pulled on the (e.g., four) cargo hold wheels, for example, by the user, for instance, when the user is walking. Even further still, in some embodiments, the cargo hold is configured to be used by the user as a trolley, as a hand truck, or both, as examples, on the (e.g., four) cargo hold wheels. Still further, in some embodiments (e.g., of a scooter or cargo hold), the cargo hold includes a telescoping handle, a pivoting handle, or both (e.g., a handle that telescopes and pivots), for example, that the user uses to push or pull the cargo hold, for instance, when the cargo hold is disconnected from the scooter and the user is walking.

[0050] Further, in some embodiments, the cargo hold connects to, and separates from, part of the scooter with a kingpin. Various embodiments of a scooter include a kingpin thatperforms this function. Still further, in certain embodiments, the kingpin is cam actuated (e.g., a cam-actuated kingpin). In some embodiments, the scooter or cargo hold includes two kingpins (e.g., for this feature), but in other embodiments, the scooter or cargo hold includes only one kingpin. Certain examples are shown in the figures. Even further, in various embodiments, the scooter includes a first wheel, a second wheel, and a frame. These wheels may be the front wheel and the rear wheel of the scooter, for example. Even further still, in some embodiments, the scooter includes a seat, for example, that a user can sit on when riding the scooter. Moreover, in certain embodiments, the scooter includes a seat column, for instance, that supports the seat from the frame, a strut adjuster, for example, that extends from the frame to the seat column, or both. Furthermore, in particular embodiments, the strut adjuster is configured to be adjusted by the user, for instance, to adjust fore and aft position of the seat.

[0051] In various embodiments, the scooter (e.g., that has a cargo hold) has an electric motor, for example, that drives the scooter when the user is riding the scooter. Further, in some embodiments, the cargo hold is configured to carry part of the scooter, for example, including the electric motor, for instance, when the cargo hold is being pushed by the user while the user is walking. Further still, in a number of embodiments, the scooter includes a traction battery, for example, that powers the electric motor, for instance, that drives the scooter when the user is riding the scooter. Even further, in some embodiments, the cargo hold is configured to carry part of the scooter, including the traction battery, for instance, when the cargo hold is being pushed by the user, for example, while the user is walking. Still further, in certain embodiments, the scooter has (e.g., includes) a solar panel, for instance, that charges the traction battery. Even further still, in a number of embodiments, the electric motor drives (e.g., at least one) rear wheel of the scooter. Moreover, in various embodiments, the cargo hold is configured to be disconnected from the scooter by the user without using tools. Furthermore, in some embodiments, the scooter is collapsible, the scooter is configured to disassemble sufficiently to be packed into a 24"x24"x44" suitcase, or both.
