A truck having configured to couple with a deck. The truck including a base and a hanger. The hanger disposed within a hanger aperture of the base. The hanger rotatably coupled with the base by a pivot assembly. The rotation of the hanger with respect to the base controlled by a compression assembly.

The disclosure relates to a skateboard and control method thereof. A skateboard deck is fixed on an axle of the skateboard, and a first sensor group and a second sensor group are sequentially arranged on the skateboard deck in a width direction. The method includes acquiring a first pressure value of the first sensor group and a second pressure value of the second sensor group; controlling the skateboard to turn to a first direction when the first pressure value is greater than the second pressure value and a difference value between the first pressure value and the second pressure value is greater than a first threshold, and controlling the skateboard to turn to a second direction when the second pressure value is greater than the first pressure value and a difference value between the second pressure value and the first pressure value is greater than a second threshold.

An electric balance car comprises a left car body, a right car body, a rotation mechanism and wheels, wherein the left car body is connected to the right car body through the rotation mechanism, the wheels are mounted on the left car body and the right car body, the axes of axles of the wheels are lower than the axis of a rotary shaft in the rotation mechanism. The electric balance car can be controlled steadily and is ingenious in structure, easy to assemble and durable.

A skateboard truck mounting apparatus is provided. The skateboard truck mounting apparatus includes a rigid body, having a first hole and a second hole, where the holes are configured to interface with the holes on a skateboard deck. Both the first hole and the second hole are equipped with self-locking mechanisms.

A truck includes a base plate, a hanger, a kingpin, and a bushing assembly. The base plate includes a coupling portion and a contact portion. The kingpin is disposed within a portion of the hanger to rotatably couple the hanger to the base plate. The bushing assembly includes at least one bushing disposed in a recess of the contact portion and in contact with the hanger. The bushing assembly including a bushing adjustment coupled to at least one of the base plate or the hanger and configured to selectively engage the at least one bushing to transition the bushing assembly between a first configuration in which the at least one bushing exerts a first force in response to rotation of the hanger and a second configuration in which the at least one bushing exerts a second force different from the first force in response to rotation of the hanger.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

A modular skateboard assembly for enabling a user to employ a pair of skateboards in the convention of a skateboard or roller skates includes a pair of skateboards which each includes a pair of rollers that roll along a support surface. Each of the skateboards is attachable to the other skateboard such that the pair of skateboards extends along a common axis thereby facilitating the pair of skateboards to be employed in the common convention of skateboards. Furthermore, each of the skateboards is detachable from the other skateboard thereby enabling the pair of skateboards to be employed in the common convention of roller skates. Each of the skateboards includes a pair of foot restraints to restrain the user's feet.

Novel side rails for self-stabilizing, one-wheeled electric skateboards and related products are disclosed. The angled frame rails of this invention and disclosure lower the center of gravity at the contact points—i.e. a rider's feet on the footpads—by as much as possible without losing any clearance at the front and rear bumpers, and tilt the gyroscope to change the zero-degree level default position. In order to achieve this, the inventive rails herein change to a downward tilt as soon as possible after the axle bolt connection points, then tilt back up before the footpad decks and continue through the front and rear of the vehicle. In one embodiment, a five-degree downward tilt of the rails allows for an approximately one-half inch drop in the center of gravity of the vehicle, thus increasing speed, stability, and safety.

Various implementations include a skateboard truck including a baseplate, a hanger, and a kingpin. The baseplate defines has a mounting surface. The hanger includes a main portion, a pivot pin, a first branch, and a second branch. The pivot pin is disposed within a pivot cup of the baseplate. The kingpin is disposed within openings in the baseplate and hanger. The branches each have curved longitudinal axes, a first portion coupled to the main portion, and a middle portion coupling the first and second portions. The second portion of each of the branches defines an axle opening. The first portion extends from the main portion toward the middle portion in a direction away from a mounting surface plane. The second portion extends from the middle portion in a direction toward the mounting surface plane. The first portions are closer to each other than the second portions are to each other.
