A suspension for a skateboard, comprising a pair of steering knuckles on opposite sides of a chassis frame of the skateboard, a pair of upper control arms connected between the pair of steering knuckles and the chassis frame, a pair of lower control arms connected between the pair of steering knuckles and the chassis frame, and a first spring damper connected between the pair of upper control arms.

Embodiments of the present disclosure include a wireless remote control or remote control application for controlling the lighting of an electronic personal transportation vehicle. Embodiments can solve problems related to sharing electronic personal transportation vehicles by uniquely identifying a user, and allowing that user to control the lighting of the electronic personal transportation vehicle. In this manner, other users can control the lighting at different times, depending on the specific person that is using the electronic personal transportation vehicle at any given time.

A skateboard and a variable-rate elastomeric steering control spring include a boardside unitary body formed of an exterior first elastomer having a first durometer on the Shore “A” scale, and an interior second elastomer coupled to the first elastomer and extending at least a length of the exterior first elastomer, the second elastomer having a second durometer on the Shore “A” scale and a through hole disposed to receive the kingpin of the skate truck, the exterior first elastomer and the interior second elastomer configured with a first irregular anti-slip junction; a roadside unitary body formed of an exterior third elastomer having a third durometer on the Shore “A” scale, and an interior fourth elastomer coupled to the third elastomer and extending at least a length of the exterior third elastomer, the interior fourth elastomer having a fourth durometer on the Shore “A” scale and a through hole disposed to receive the kingpin; and wherein the first, second, third and fourth elastomers comprise at least two durometers on the Shore “A” scale between 65 A and 100 A to enable the boardside unitary body and the roadside unitary body to form the variable-rate elastomeric steering control spring when disposed on the king pin of the skate truck.

A personal vehicle system including a control system and at least one wheel motor coupled to the personal vehicle system and subject to control by the control system. A control system for a personal vehicle system including steps for calibrating the control system, where the control system includes a sensor system having load sensors incorporated into the personal vehicle system and also having lean forward and lean backward outputs, a user interface that prompts a user to lean forward and backward and allows a user to input a sensitivity value, and an electronic hardware component for calculating a normalization value where the wheel motor current is controlled as a function of the normalization value.

An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

A personal mobility device includes a frame connected to at least one wheel, a connection part on the frame, a boarding part connected to the connection part to be tiltable, a first sensor disposed on the frame to measure an inclination of the frame, and a second sensor disposed on the boarding part to measure an inclination of the boarding part.

A multi-wheel truck that minimizes wheel interactions with discontinuous and uneven surfaces. The truck provides a suspension system that absorbs impact force caused by uneven surfaces and a unique attack angle that allows obstacles to be traversed when approached from a wide range of angles.

The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not proportionally responsive to tilting over the expected range of tilting.

A standup paddle-board skateboard apparatus for mimicking the experience of standup paddle-boarding on land. Functional elements of the apparatus may include wheel-cutouts allowing for increased articulation without experiencing wheel-bite, a modified truck angle for improved turning, central handle, and axle cutouts allow for increased board tilt without the axle impacting the board.

In an aspect, a foot-deck based vehicle is provided, comprising a foot-deck, a front wheel arrangement, a rear wheel arrangement and a biasing member. The foot-deck has a front end and a rear end. The front wheel arrangement is proximate the front end. The rear wheel arrangement is proximate the rear end. The foot-deck has a first foot-deck portion and a second foot-deck portion that is rearward of the first foot-deck portion and that is movable relative to the first foot-deck portion. The second foot-deck portion extends rearward of the rear wheel arrangement. The biasing member biases the second foot-deck portion towards a home position relative to the first foot-deck portion. The second foot-deck portion is moveable from the home position downward to a biased position so as to store potential energy in the biasing member such that the biasing member urges the first foot-deck portion upward.
