A method for recharging an electrical energy storage device of all or some of a plurality connected to the chain. All the vehicles connected to the chain being referred to as the stock. Each vehicle includes an electronic circuit connected to the energy storage device. An electric current flowing between the electronic circuits of at least two consecutive vehicles among the vehicles in the stock recharges the energy storage device or devices.

A two-wheeled vehicle includes a frame assembly, a plurality of ground-engaging members for supporting the frame assembly, and a cooling assembly positioned below a head portion of the frame assembly and intermediate vertically-extending frame tubes of the frame assembly. A lower end of the cooling assembly is coupled to a lower end of the vertically-extending frame tubes, and an upper end of the cooling assembly is frictionally retained at an upper end of each of the vertically-extending frame tubes.

The invention relates to a vehicle, in particular a lightweight vehicle. The vehicle can be converted from a driving configuration to a seating configuration by reducing the distance between a front wheel structure and a rear wheel structure.

A structure of a human-powered vehicle including at least one coupling kit having a fastening zone and a complementary fastening zone. The fastening zone being configured to be coupled to the complementary fastening zone presented by a second similar vehicle or by a fixed terminal. A vehicle and/or terminal including at least one coupling kit of the structure. A method of recharging battery of such vehicle.

A leg actuator mechanism, a method of manufacturing the leg actuator mechanism, and a doll implementing a leg actuator mechanism is provided. The leg actuator includes an upper leg mechanism comprising a hip end and an opposing knee end. The leg actuator also includes a lower leg mechanism comprising a first end and an opposing second end, wherein the first end of the lower leg portion is operably coupled to the knee end of the upper leg portion. The leg actuator further includes a follower mechanism. The follower mechanism includes a mounting defining a follower pathway configured to receive a follower joint. The follower mechanism also includes an upper follower connector and a lower follower connector. The follower mechanism moves at least one of the upper leg mechanism or the lower leg mechanism when activated.

A vehicle for a person to ride on a ground surface includes a rigid frame that has front and rear ends and at least a seat on a top side of the frame. A steering mechanism disposed proximate the front end of the frame is adapted for allowing the person to steer a front wheel. A steering fork may include two lower fork members each selectively detachable from two upper fork members of the steering fork at two telescoping attachment arrangements that includes a front suspension arrangement. A rigid frame extension has a front end that is pivotally fixed proximate the rear end of the frame. The frame extension includes at least one rear wheel fixed with a rear end of the frame extension. A motor is fixed with the front wheel and is electrically connected with at least one battery and a throttle switch fixed with the steering mechanism.

A vehicle frame's coupler structure that connects separable frames for easy assembly and disassembly, at a low cost. Further, the couple structure can provide a vehicle that is easy to operate, without affecting the user when in use. The vehicle frame's coupler structure includes combining a Front-side Coupler Inner Face (8) with Rear-side Coupler Inner Face (9), and after making sure all components of (8) and (9) are in place (no protruding edges, etc.), and using Bolt (15) to fasten Part (6) with Part (7). The end result is the coupler system of the vehicle.

The modular bike is a chainless biking device that may be quickly converted from a road bike to an all-off-the-road bike or a racing bike. To accomplish this, the device includes a frame, a drive box, and a plurality of wheels that are detachably attached to one another in an efficient and stable fashion. The device utilizes a hydraulic drive mechanism, which is more efficient than a chain drive mechanism. Further, a quick release mechanism associated with the wheel hubs of the modular bike enable users to quickly change the wheels from the frame for tire and/or spoke repairs. Additionally, the offset arrangement of the drive box and the frame along with the quick release mechanism of the wheels enable users to transform the bike to various configurations to match to the purpose/terrain of the ride etc.

A foldable human-powered vehicle upon which users can ride is described. The vehicle includes a wheel assembly, a deck assembly, a seating assembly, a handle assembly, a deck support frame, and a brake assembly. The vehicle also includes a first and a second bicycle having a first handle disposed opposite a second handle. A first handle of the second bicycle is affixed to a second handle of a portion of the handle assembly to affix the second bicycle to the vehicle. A second handle of the first bicycle is affixed to a first handle of a portion of the handle assembly to affix the first bicycle to the vehicle. The vehicle also includes a rear component affixed to a portion of the deck assembly, where a head tube of a third bicycle is affixed to the rear component to affix the third bicycle to the vehicle.

A scooter includes a scooter body with substantially triangular front and rear body portions. The substantially triangular front body portion has a front side and a first connecting side. The front side and the first connecting side of the front body portion form a first acute angle. The substantially triangular rear body portion has a rear side and a second connecting side. The rear side and the second connecting side of the rear body portion form a second acute angle. The first and the second connecting sides are connected so as to linearly slide with respect to one another such that when the scooter body is in an extended state the front side is in a greater distance from the rear side than a distance when the scooter body is in a compact state.
