An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

A nose-dive prevention device for a one-wheeled motorized transportation device is disclosed, which has wheels that strike the ground in the event of a nose-dive situation, instead of the bumper, which could otherwise become abruptly hung and thus throw the rider. The nose-dive prevention device has a base for attachment to the front of the one-wheeled motorized transportation device, and one or more wheels connected to and extending from the base. The wheels are positioned to interpose between the front end of the one-wheeled motorized transportation device and the ground and contact the ground when the front end exceeds a nose-dive angle. However, under normal riding conditions, the wheels are spaced above the ground at a height sufficient to allow normal angular variability of the riding platform needed for control of the one-wheeled motorized device.

A personal transport includes a deck configured for supporting a rider in a standing position. At least one wheel assembly is mounted on a bottom surface of the deck, the, or each, wheel assembly having at least one wheel so that the deck can travel over a substrate. An operator handle is substantially rigidly mounted on a rear end of the deck and extends rearwardly from the deck so that an operator, standing on the substrate, can grasp the operator handle and push the apparatus along the substrate, or tilt the apparatus relative to the substrate, while the rider is supported on the deck. A rider handle mounted on one of the deck and the operator handle and positioned so that the rider can grasp the rider handle for balance while supported by the deck.

A bifurcated truck in a laterally-sliding board wheel assembly enables the freeboard to seamlessly transition from carvingas associated with a traditional skateboardto new omnidirectional motions, in which the board can easy travel forward, backwards, sideways or in any other directional combination. The wheel assembly of this invention employs a bifurcated truck system having two independent suspension arms, both operating independently from one another and from the board's castering wheels. The wheel assemblies are mirrored at each longitudinal end of the board, resulting in the board's ability to carve, slide or skidand easily transition back and forth among each of these modesproviding the rider a sense of stability and freedom commonly associated only with snowboarding.

Improved skateboards and methods of obtaining or providing skateboards with improved trucks. Trucks have two axles or axes, two primary wheels, and two secondary wheels, and skateboards have eight wheels, four in front and four at the rear portion of the skateboard. The four primary wheels support most or all of the weight of the skateboard when the skateboard is on a flat surface, and the two secondary wheels support the weight of one portion of the skateboard (e.g., front or rear) when the primary wheels cross a crack (e.g., a sidewalk contraction joint). In various embodiments, the secondary wheels are located outboard of the primary wheels. Further, in a number of embodiments, the axis of rotation or axle of the primary wheels remains parallel to that of the secondary wheels, whether the skateboard is going straight or turning.

Provided is a ball skate sole structure which can be customized for each individual or each sport. This ball skate sole structure includes: a base plate having a plurality of first holes and a plurality of second holes; at least one ball roller member, the at least one ball roller member being disposed in the first hole selected from among the plurality of first holes; and at least one brake member, the at least one brake member being disposed in the second hole selected from among the plurality of second holes.

A self-balancing vehicle includes two vehicle bodies, respectively including a carrier assembly, a moving mechanism, a control assembly, and a power supply device coupled to the control assembly. The carrier assembly includes a frame and a foot platform coupled to the frame to form a cavity. The frame recess towards the foot platform defining a groove. The moving mechanism includes a wheel disposed on the groove side of the frame and a driving member. Part of the wheel is accommodated in the groove. The driving member drive the wheel to rotate relative to the frame. The control assembly includes a posture sensor detecting a tilt angle of the frame with respect to the vertical direction and a controller controlling a rotation speed of the driving member. At least one of the power supply device and the controller is accommodated in the cavity.

A personal transport includes a deck configured for supporting a rider in a standing position. At least one wheel assembly is mounted on a bottom surface of the deck, the, or each, wheel assembly having at least one wheel so that the deck can travel over a substrate. An operator handle is substantially rigidly mounted on a rear end of the deck and extends rearwardly from the deck so that an operator, standing on the substrate, can grasp the operator handle and push the apparatus along the substrate, or tilt the apparatus relative to the substrate, while the rider is supported on the deck. A rider handle mounted on one of the deck and the operator handle and positioned so that the rider can grasp the rider handle for balance while supported by the deck.
