Various powered wheeled board vehicles are disclosed. In some embodiments, the vehicle includes a deck having a forward portion and a rearward portion. At least one front wheel can be connected with the deck under the forward portion. The front wheel can be configured to swivel about a first axis and rotate about a second axis. A powered wheel can be connected with the rearward portion. In some configurations, the rear wheel comprises a hub motor.

Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

A caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.

A wearable mobility device comprising a base for the placement of a shoe, the base including a heel-support section, a battery pack, a tail reflector, and a wireless receiver. The device including a first wheel having a wheel hub motor embedded therein, the motor rotatably connected to a first partial axial shaft connected to the base. The device including a second wheel having a wheel hub motor controller embedded therein, the motor controller rotatably connected to a second partial axial shaft connected to the base and operative to control a speed of rotation of the first wheel and the second wheel. The device also including a remote control for controlling the speed of rotation of the first wheel and the second wheel, the remote control operative to transmit one or more control signals to the wireless receiver, the wireless receiver being electrically coupled to the motor controller.

The present invention relates to a spring-form flexible skateboard. The skateboard comprises: front and rear plates (3, 5) disposed separated from each other by a predetermined distance: a flexible torsion part (7) which is integrally disposed between the front and rear plates (3, 5), and has a spring structure of a wrinkled shape, wheels (9) which are rotatably mounted on brackets (13) rotatably mounted on the front and rear plates (3, 5); and a support (31) which is disposed between the front and rear plates (32, 34) so as to support the torsion part (7), and of which one end is connected to the front plate (32) and the other end is connected to the rear plate (34) while the milled section supports the torsion part (36), thereby making it possible to prevent sagging towards the rear.

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 discloses an electric four-wheel balance vehicle includes a housing, a pedal device, a balancing device, a driving device, and a power supply device. The balancing device is provided in the housing. The pedal device includes a pedal, a fixed frame, and an elastic pad. The housing is provided with two pedal holes. The pedal is movably embedded in the pedal hole, and is limited in the housing by the fixing frame located on a top of the pedal. The elastic pad is provided between the housing and the pedal. The balancing device is provided in the housing, and is coupled with the pedal in a transmittable manner. The driving device includes a control board, two front motor-wheels, and two rear universal wheels. The balancing device is connected to the control hoard in a communicating manner.

A side-by-side pair of platforms, each equipped with a foot-pad, are coupled in a manner to form a vehicle, and are supported (a) at the rear by a truck-mount under each platform, integrated with a shared axle assembly fitted at its ends with a pair of rear wheels, located at opposite sides of the vehicle, and (b) at the front by a tilt-turn mount system including at least one front wheel, typically a caster-mounted roller, accomplishing dual-platform tilt-turning in response to the user's body movements simulating superior snow-skiing techniques, thus enabling sustained self-propulsion by user body movements and providing recreation, training and practice for skiers of all ages and skill levels.
