A self-balancing board is provided, comprising a platform having a first foot deck portion to substantially support a first foot of a rider, and a second foot deck portion to substantially support a second foot of the rider. A wheel assembly is positioned between the first foot deck portion and the second foot deck portion along a longitudinal axis of the platform, and comprises a wheel having a rotation axis that is generally orthogonal to the longitudinal axis of the platform, and a motor unit driving the wheel. An orientation sensor senses the orientation of the platform. A controller receives data from the orientation sensor and controls the motor unit in response to the received data. At least one suspension interface between the platform and the wheel assembly has a single degree of freedom generally orthogonal to the rotation axis of the wheel and to the longitudinal axis of the platform, and biases the platform towards a rest position.

A safe hovering skate board unit capable of being driven by a user is disclosed. The hovering skateboard includes a first board to receive the user, one or more first magnetic source, configured with the first board, to emit magnetic field, a second board magnetically coupled with the first board, one or more second magnetic source configured with the second board to repel the magnetic field and facilitate the first board to hover over the second board. Further, the unit includes the ground engaging wheels attached to the second board moves in the direction driven by the user. Furthermore, the unit may include a specialized safety system for ensuring safety of the user by controlling one or more components corresponding to the hovering skateboard unit based on one or more factors corresponding to the user. Further, a corresponding method of operating the hovering skate board unit is also disclosed.

One-person vehicle (1) for urban transport comprising a transport deck (2) for one user of the vehicle (1), trucks (3) for the displacement of said transport deck (2), and control arms (4) for said trucks (3) which are attached to said transport deck (2) so that they can pivot with respect to said trucks (3) when the user swings the deck (2) for changing the traveling direction of the vehicle (1), and is characterized by the fact that each of said trucks (3) comprises a pivot (5) to be inserted into one of said control arms (4) and a damper assembly (19) which is interposed between the pivot (5) and the arm (4) rotating about said pivot (5), allowing said damper assembly (19) to compensate on said arm (4) the weight force that swings the deck (2) and to drive the return to the centre of said arm (4) when said force yields.

An electronic control device for an electric skateboard that obviates the need for remote control is described. The device includes one or more hub motor integrated into a wheel hub or coupled to an axle of the electric skateboard and electric control unit that detects speed or acceleration of the hub motor and adaptively controls speed or torque of the hub motor based on feedback from rider's manual operation of the skateboard.

A powered two-wheel vehicle includes a chassis extending between a rotatable front fork and a fixed rear fork. A deck is attached to the chassis to enclose a compartment. A front wheel is rotatably attached to the front fork and a rear wheel is rotatably attached to the rear fork via a hub motor. The steering assembly includes a head tube supported above and in front of the deck by a pair of arched frame tubes, a steering tube rotatably connected to the head tube, and a rotational damper connected between the head tube and the steering tube.

The present invention is directed to an undercarriage of a person powered wheeled vehicle and, more particularly, to a cantilevered spring for absorbing shock and vibration.

A hovering skate board unit capable of driven by a user is disclosed. The hovering skateboard includes a first board to receive the user, one or more first magnetic source, a second board magnetically coupled with the first board, one or more second magnetic source and at least one ground engaging wheel. The first magnetic source is configured with the first board to emit magnetic field. The one or more second magnetic source is configured with the second board to repel the magnetic field emitted from the one or more first magnetic source and further facilitates the first board to hover over the second board. The ground engaging wheels attached to the second board moves in the direction driven by the user. Further, a corresponding method of operating the hovering skate board unit is also disclosed.
