A powered wheeled riding device is configured to receive left and right foot inputs from a user and in response control a left motor and a right motor to move respective left and right wheels forwardly and backwardly consistent with the left and right foot inputs in order to steer the device without changing a direction of the wheels relative to a frame of the riding device. The riding device has at least one rear wheel that is not powered. The rear wheel is mounted on a wheel mount that rotates freely about a vertical axis so that the rear wheel freely is directed in any direction.

A tricycle has a forward oriented fork member (20) supported for rotation about a steering axis (14) of the tricycle, a handle bar (50) mounted to the fork member, a cargo unit (24) supported by the fork member, and a pair of transversally spaced linkages (30), wherein each linkage at a proximal end is linked to the fork member and at a distal end supports a respective front wheel (16) of the tricycle. The cargo unit and the linkages are shiftable between respective forward and backward end positions to thereby transform the tricycle to a wheel cart and vice versa.

An electric powered bicycle includes front and rear wheels (102, 104) that swivel relative to a midframe (106). The midframe (106) includes a pedal driven generator-motor (108), and each wheel (102, 104) includes a motor-generator. The wheels (102, 104) may swivel to opposite sides of the midframe (106) about 180° to move into a collapsed configuration. Swivel may be on single axis joints (162, 168) with tilted swivel axes. In the collapsed configuration, the bicycle is suitable to be carried and stored and may also be utilized in a unicycle/exercycle configuration. By swiveling the wheels (102, 104) to the same side of the midframe (106) about 90°, the bicycle can be placed into other configurations including a walker, a rolling seat, and a chariot to carry packages or a person.

A riding vehicle includes: a main body supporting a wheel and on which a steering stay and a seat stay are erected at an interval in a traveling direction; a handle provided on the steering stay; a pedestal portion fixed to an upper end of the seat stay; a seat rotatably connected to the pedestal portion, and configured to switch between a riding state where the seat stands upright to cover the pedestal portion from above so as to be in an arrangement suitable for riding and a cart state where the seat is inclined in a traveling direction away from the steering stay to open an upper portion of the pedestal portion so as to be in an arrangement suitable for conveyance movement with baggage placed thereon; and a stopper interposed between the pedestal portion and the seat and regulating the seat in the riding and cart states.

The electric stroller comprises a frame, a child seat, an operator seat, a plurality of wheels, a port motor, a starboard motor, a control circuit, and a battery. The electric stroller may be a self-propelled conveyance. The child seat may be supported by the frame and may be adapted to transport a child. The operator seat may be coupled to the frame behind the child seat and may be adapted to transport an operator. A port driven wheel may be propelled by the port motor and a starboard driven wheel may be propelled by the starboard motor with the speed and direction of the port motor and the starboard motor controlled independently.

A two-wheeled, variable configuration bicycle having a frame, a handlebar, a saddle, pedals with pedal cranks and a drive gear rotatably mounted on the frame, a front wheel mounted on the front fork, a rear wheel with a sprocket mounted on a rear fork. The bicycle includes the upright configuration and the recumbent configuration, and in recumbent configuration, the bicycle provides support for the back of the cyclist. The frame (2, 2′) are provided two front mounting locations for attaching the front fork (14), wherein the first front mounting location is provided for attaching the front fork (14) in the upright configuration, and the second front mounting location is provided for attaching the front fork (14) in the recumbent configuration. The frame (2, 2′) are provided two rear mounting locations for attaching the rear fork (17).

A vehicle including a front module including a front wheel and a rear module selectively moveably connected to the front module, the rear module including a rear wheel. The vehicle further includes an electric motor assembly, a mode selector, at least one extension assembly connected between the front module and the rear module for selectively extending and retracting to provide a selective variation in an overall length of the vehicle; and a vehicle control unit being communicatively connected between the mode selector and the electric motor assembly. The vehicle control unit performs a method for selectively changing the overall vehicle length. The method includes receiving from the mode selector an indication to change the overall length, determining that the front wheel is rotationally locked, and causing an electric motor to drive the rear wheel such that the rear module translates relative to the front module.

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.
