A skateboard truck that is adjusted for different amounts of torsional stiffness. The axle of the truck is tensioned to change the torsional stiffness of the truck. The truck includes a fork shaped structural arm having tongs on the distal end. The ends of the tongs include mounting for the axle which supports the wheels. The tension in the axle determines the amount of torsional stiffness. Additionally, the distance between the wheels is adjustable to affect the torsional stiffness.

The present disclosure provides a detachable training wheel apparatus for mounting to the underside of a skateboard tail or nose to assist with balancing a user during manoeuvres which require tipping of the skateboard onto two wheels, while allowing the board to continue rolling along the ground with minimal friction. The apparatus comprises a single wheel mounted to a mounting board by a pair of supports and a central bushing, with the opposing side of the mounting board having a flat surface provided with attachment means for detachably coupling to the skateboard underside, such as a hook and loop surface.

A skateboard includes a deck, at least a front wheel set and a rear wheel set. The front wheel set, which is arranged at a bottom of the deck at a position close to a front end thereof, includes at least one rigid and rotatable front wheel frame and at least two front wheels. The rear wheel set, which is arranged at a bottom of the deck at a position close to the rear end thereof, includes at least one rigid and non-rotatable rear wheel frame and at least two rear wheels. The outer side of the wheel is circular or arc-shaped. The structure of the skateboard allows the user to change a center of gravity and to lift the sides of the board with foot, so as to only rely on the outer arc of the left or right front and rear wheels to slide, while the rotatable front wheel frame in the left or right side may still be utilized for rotating in the forward direction, which allows a skateboard experience of forward or changing the travelling direction.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

An electric skateboard comprising: a deck; a front truck and a rear truck; a pair of wheels rotatably connected to each truck, wherein one or both pairs of wheels are driven by sensored motors; a communications module configured to receive control instructions from a wireless remote control and to transmit data to one or more external devices; a controller in communication with the communication module and the motors; and a battery supplying power to the motors, communications module and controller.

Described herein are systems and apparatuses for securing and locking a ride-able board to a fixed object. In general, a ride-able board may optionally include a planar body configured for moving across a solid surface and for carrying a rider. In general, a ride-able board may include a planar body mounted to a steering apparatus and any number of wheels. In a preferred embodiment, the security device containing a shackle and housing comprising an open cavity is used to secure the board to any fixed object. In a preferred embodiment, the housing cavity slides over the steering apparatus and has two openings for each end of the shackle. The lock secures the shackle in place and prevents the removal of the board from the fixed object. The housing working in conjunction with the u-shackle prevents removal of the locking device from the board.

A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.

A skateboard comprising a board including a front portion and a rear portion, the front and rear portions being disposed in a horizontal plane such that a uniform gap is formed there between; a front wheel assembly including a pair of wheels, the front wheel assembly being secured to a bottom surface of the front portion of the board; a rear wheel assembly including a pair of wheels, the rear wheel assembly being secured to a bottom surface of the rear portion of the board; and a steering control assembly secured to both the front portion and the rear portion of the board, wherein the steering control assembly is configured to allow pivotable movement of the front portion and the rear portion of the board about both a longitudinal center axis of the skateboard that lies in a horizontal plane and a vertical pivot axis that is transverse to the longitudinal center axis of the skateboard.

A skateboard comprising a board having an independent suspension and steering assembly connecting two wheels to the board. The suspension assembly comprises a support frame rotatably coupled to an underside of the board. The steering assembly comprises a steering crank fixed to and extending from an underside of the board. The suspension assembly further comprises for each wheel: a spindle for rotatably supporting the wheel; a knuckle for holding the spindle; an upper and a lower suspension arm pivotably coupled to the support frame at an upper and at a lower point of the support frame, respectively, and also pivotably coupled to the knuckle at an upper and at a lower point of the knuckle; and a spring for resiliently holding the knuckle against the board. The steering assembly further comprises for each wheel: a tie rod coupled by a ball joint to the steering crank and to the knuckle.

The invention discloses a skateboard wheel tyre, including an annular cover tyre, embedded parts and a first connector, wherein the first connector is located on the inner side of the annular cover tyre, and a cavity is formed therebetween; n second connectors are disposed in the cavity, wherein n is an integer greater than or equal to 1, and the second connector is connected to the annular cover tyre and the first connector; the annular cover tyre, the first connector and the n second connectors are integrally formed from the same material; the embedded parts are embedded into gaps among the annular cover tyre, the first connector and the n second connectors to fill the gaps, and the embedded parts are made from a material which is the same as the annular cover tyre in type but different in color and hardness.
