A system and method for mounting one or more accessories to a vehicle with forks is disclosed. The system can include a frame comprising mounting plates, the mounting plates including at least an axle hole and a fork stop hole. The frame can also include frame rails to connect the mounting plate to an accessory mount. The system can be mounted to the forks of the vehicle using the axle hole and an axle. A fork stop can be placed in the fork stop hole and can include one or more interface points to fit the bottom of the forks. The fork stop can transmit forces from the accessory to the forks in a linear manner and to a location where the forks have additional strength. The fork stop can be designed such that it bends in response to an impact rather than breaking the forks.

A child's riding vehicle can be quickly reconfigured between a balance bike configuration and a pedal-powered bicycle configuration, suitable for children of different ages, without removing any parts to be stored separately. The pedal crank arms can be repositioned on the crank and the pedal axles can be pivoted so that in the balance bike configuration: the pedal crank arms are positioned adjacent to one another and generally upward; the pedal axles are pointed mostly rearwardly but also slightly inwardly rather than extending transversely side-to-side; and the crank arms and pedal axles are telescoped in. The result is that in the balance bike configuration the pedals and crank arms are compacted and folded out of the way so as not to interfere with the child riding the vehicle.

A chainless bicycle for child includes a frame and a power gearing device. The frame has a seat tube between the front wheel and the rear wheel, with a passive gear axially disposed on a hub of the rear wheel. The power gearing device is disposed on the frame between the seat tube and the rear wheel. The power gearing device includes an active gear and a transmission gear meshed with the active gear. The transmission gear is meshed between the active gear and the passive gear. The power gearing device further includes a crank set disposed on two sides of the active gear for driving the active gear to rotate. Therefore, the passive gear is driven through the transmission gear to rotate in an identical direction with the active gear. Thus, the meshing structure of the present invention improves the safety of children.

A vehicle (1) is provided and includes a frame (10), a seat (20), front and rear wheel sets (1012, 1014) provided at front and rear ends of the frame, and a handlebar (30). A wheel set is an adjustable wheel set that includes a wheel support (1016), a first wheel (52b) and a second wheel (52c) rotatably supported on the wheel support. The wheel support includes a first connector (60) pivotably mounted to the frame for pivoting movement about a connector axis that lies in a generally vertical-longitudinal plane. The wheel support is pivotable between a first position in which the wheel support holds the first and second wheels canted such that their upper ends are closer together than their lower ends, and a second position in which their upper ends of the first and second wheels are farther from one another than their lower ends.

A personal mobility apparatus includes: a support platform having a pair of footplates and a cavity; two drive wheels disposed on both sides of the support platform, respectively; and a steering wheel connected to the support platform to be received in the cavity. The steering wheel is connected through a telescopic tube to be received in the cavity of the support platform and the telescopic tube includes a first tube and a second tube moving telescopically with respect to the first tube.

Some embodiments are directed to a foldable vehicle for use as a vehicle if being unfolded, and for use as a trolley if being folded. The vehicle in its folded configuration may also be placed in an upright parking position. The vehicle includes a first side frame coupled to a first wheel, a second side frame coupled to a second wheel and a coupling frame. The coupling frame includes a hinge joint between a first end and a second end of the coupling frame. The first end is hinged to the first side frame and the second end is hinged to the second side frame. When the first wheel translates towards the second wheel, the hinge joint moves from one side of the second wheel to the other side of the second wheel.
