A personal transportation vehicle comprises a carrier, a control device, a first pair of wheels and a second pair of wheels, wherein the first pair of wheels are fixed in a direction and the second pair of wheels are mounted on swivels disposed below the carrier, each of the first pair of wheels and the second pair of wheels comprises a first wheel and a second wheel, and the first pair of wheels and the second pair of wheels are arranged aligned and parallel to each other below the carrier, a first controller, a first driving device for driving the first wheel of the first pair of wheels, a second controller and a second driving device for driving the second wheel of the first pair of wheels. The control device is configured to transmit signals to the first controller and the second controller to control the first driving device and the second driving device, such that the second pair of wheels are swiveled and driven by a difference between the rotational speeds of the first wheel and the second wheel of the first pair of wheels to determine a movement direction of the transportation vehicle.

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.

Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.

A bifurcated spring-tethered electric skateboard is bifurcated into a front deck and rear deck with each deck having independently powered wheels. The skateboard has a mounted power source, generating electrical power for a motor that is transmitted to the wheels. A controller is configured to control the speed of the motor, and the wheels. The controller is electrically connected to the motor for direct control, or a wireless transmitter for remote control. A spring assembly connects the decks, creating a spring-tensioned effect between the decks while riding the skateboard. The uneven ride requires that the trucks do not rotate fully. A cable that connects the electrical components can also be damaged from excessive rotation of the trucks. Thus, the skateboard also provides a restriction tab at the bottom surface of the decks that engages the trucks to limit rotations thereof.

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.

A personal transportation vehicle comprises a carrier, a control device, a first pair of wheels and a second pair of wheels, wherein the first pair of wheels are fixed in a direction and the second pair of wheels are mounted on swivels disposed below the carrier, each of the first pair of wheels and the second pair of wheels comprises a first wheel and a second wheel, and the first pair of wheels and the second pair of wheels are arranged aligned and parallel to each other below the carrier, a first controller, a first driving device for driving the first wheel of the first pair of wheels, a second controller and a second driving device for driving the second wheel of the first pair of wheels. The control device is configured to transmit signals to the first controller and the second controller to control the first driving device and the second driving device, such that the second pair of wheels are swiveled and driven by a difference between the rotational speeds of the first wheel and the second wheel of the first pair of wheels to determine a movement direction of the transportation vehicle.

A four-wheel sensor controlled vehicle having a base and a control box installed with a battery and a control panel; two driving wheels are installed at the bottom surface of the base close to the front edge of the base, and two universal wheels are installed at the bottom surface of the base close to the rear edge of the base. The driving wheel has a hub assembled with a hub motor assembly of a motor. The base is installed with four weighing sensors at four corners, the first weighing sensor and the third weighing sensor respectively correspond to the fore sole and rear sole of the left foot, the second weighing sensor and the fourth weighing sensor respectively correspond to the fore sole and the rear sole of the right foot. The control panel is connected with the motor and the weighing sensors.

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.
