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.

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 self-balancing board is provided, comprising a primary wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly, and a first brake element. The primary wheel assembly comprises a primary wheel and a motor driving the primary wheel. The platform is secured to the primary wheel assembly and has a foot deck. The at least one sensor senses the orientation of the platform. The controller receives data from the at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform distal the primary wheel assembly, and is elevated from contacting a flat surface upon which the primary wheel rests when the foot deck is parallel to the flat surface. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.

An apparatus and method for reducing the incidence of sudden stoppage while riding a self balancing skateboard. Wheels are mounted with the front of the bumper, or integrated within a special replacement bumper, of the skateboard to provide a low-friction rollout instead of an instant stop, allowing the rider to maintain control in the event that the front of the board contacts the ground. The wheels protrude from a lower surface of the bumper to limit contact of the bumper with the ground.

The embodiments of the present disclosure provide roller-skating device and electric balance vehicle, including: footboard, one or more ground contacting elements, first sensor, one or more driving elements and first controller. Footboard is coupled to first sensor and ground contacting elements which are coupled to driving element, and first controller is coupled to first sensor and driving element. Footboard is configured to stand on one foot, and to tile forwards or backwards in the case of one foot standing; one or more ground contacting elements are configured to act due to actuation of driving element; first sensor is configured to sense posture of driver on footboard; one or more driving elements are configured to generate output signal for controlling action of ground contacting elements and maintaining entire roller-skating device in balance; and first controller is configured to control generation of output signal depending on posture.

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.

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 self-balancing board is provided, comprising a primary wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly, and a first brake element. The primary wheel assembly comprises a primary wheel and a motor driving the primary wheel. The platform is secured to the primary wheel assembly and has a foot deck. The at least one sensor senses the orientation of the platform. The controller receives data from the at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform distal the primary wheel assembly, and is elevated from contacting a flat surface upon which the primary wheel rests when the foot deck is parallel to the flat surface. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.
