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.

Skateboard trucks and skateboards using the improved trucks are disclosed. Truck according to the present invention can comprising a hanger with wheels. A base assembly is included having an at least partially hollow housing section. The hanger is rotationally mounted to the base assembly. The hanger also comprises a hanger portion that is within partially hollow housing section. Compressible spring elements are included within the partially hollow housing section, wherein the hanger portion operates on the compressible spring elements when the hanger rotates in relation to the base assembly. Skateboard are also disclosed that utilize the truck. One or more trucks are mounted to the skateboard deck with the truck having internal compressible spring elements that are compressed when turning the skateboard. The internal compressible spring elements also expand to return the truck to a neutral position when the skateboard is not turning.

A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded shaft nut assembly permanently affixed within the baseplate. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.

Devices and methods of transport are disclosed. Various embodiments include structural aspects related to steering and changing the direction of conveyances including features which utilize leaning or shifting of weight as part of turning.

A moving wheel platform that minimizes wheel interactions with noncontinuous and uneven surfaces. The platform provides rotation-inhibiting structures onto or into the moving wheel platforms that aids with eliminating wheel bite.

An electric skateboard has a frame assembly that includes a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame includes a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned in at least partially in the enclosure. Front and a rear trucks are mounted to the bottom of the deck. At least one of the first and front and rear trunks is coupled to first and second wheels mounted on axles of the front and rear trucks. The front truck is mounted on the front end and a rear truck is mounted on rear end of the deck. First and second wheels are powered by one motor with a differential and a shaft coupled to the first and second wheel. The motor is coupled to the shaft to rotate the first and second wheels. The motor is electrically connected to the battery pack through a rear channel. The motor rotates the first and second wheels in the same directions and propels the electric skateboard forward and backward.

A moving wheel platform that minimizes wheel interactions with noncontinuous and uneven surfaces. The platform provides rotation-inhibiting structures onto or into the moving wheel platforms that aids with eliminating wheel bite.

The utility model relates to the field of skateboard fitting, specifically relating to an adapter for surfskate comprising a fixing plate, a rotating plate, an centre shaft screw and a locking nut wherein said fixing plate and rotating plate link together via centre shaft screw and locking nut; a torsion spring is sleeved on centre shaft screw between fixing plate and rotating plate, and the top of torsion spring is fixed on fixing plate, and the bottom is fixed on rotating plate; said centre shaft screw located on top and bottom of rotating plate are sleeved with a thrust bearing wherein thrust bearing on the top of rotating plate is provided within torsion spring; on the side of fixing plate closing to rotating plate is equipped with limiting groove and on the side of rotating plate closing to fixing plate is equipped with limiting block matching with limiting groove.
