A rotating wheel and a balance scooter are provided. The rotating wheel includes a motor and an acoustic unit. The motor includes a stator, a rotor sleeved on a periphery of the stator and rotatable relative to the stator, and a motor shaft passing through the stator and defining a motor hole penetrating through the motor shaft. The motor hole is configured to receive a power wire and an audio wire. The acoustic unit is arranged on the motor shaft and electrically connected to the power wire and the audio wire.

A pair of foot lift attachments for attachment to single-wheel motorized electric skateboards, and combinations thereof. The foot lift attachments include a right foot lift attachment and a left foot lift attachment, each having a first concave curved outer facing side wall configured to be engaged on a curved support surface of either of a fender covering the single wheel, or a curved support surface of a mounting bracket secured at each side of the opening for the single wheel, and each having a convex curved top end wall with a concave curved underside configured to laterally receive and overlap the medial side and a top portion of the skateboard rider's foot and footwear worn on the foot to enable the rider to lift the skateboard off the ground with their feet and perform freestyle skateboarding maneuvers and aerial moves and jumps.

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.

A motorized or non-motorized multi-wheeled skateboard assembly including a board deck to support the user, a board having a top side, a bottom side, a flat and a rounded end, linkages, hinges, a steered wheel assembly, an input device and a drive assembly. The steered wheel assembly improves maneuverability, turn radius, and stability. The user steers the skateboard assembly by altering pressure between the top side first end and the top side second end causing the steered wheel to turn, thus manually steering the board. This change in pressure is also altered between the first linkage and second linkage in direct or inverse relation to altering pressure between the top side first end and the top side second end of the board deck.

An elastic band for a skateboard. The band is an elastomer such as EPDM and stretches over the deck of the skateboard longitudinally with a central span under which the rider's feet can be inserted. The band has opposed ends with loops that may be wrapped around the skateboard trucks under the deck. The band is stretched taut, but has sufficient flexibility to enable the rider's feet to be inserted under the central span. Equipping a board with the band enables a rider to perform various tricks that ordinarily require the hands, and the feel is similar to a snowboard, which provides a way to practice snowboarding on the street.

The invention comprises a truck and riding devices with a lean steering spatial mechanism comprised of rigid bodies and a single compliant body connected by joints forming a closed kinematic chain wherein the compliant body provides compression, tension, and torsional return spring forces for multi-axial functionality within the constraints of the lean steering spatial mechanism, allowing for the combined functionality of deep deck lean, improved lean steering control over a wider range of speed, improved speed stability, and full load bearing suspension. The invention has additional degrees of freedom and additional primary motions of floating and suspension.

A boss for use with a roller skate and attached to a king pin of the roller skate and adapted to removably support an axle housing. The boss supports a pivot pin adaptor having an adjustable pin fixed into place by a lock nut. The pivot pin adaptor includes a shoulder internally abutting the boss and different angled shoulders can be attached to the boss to adjust the angle of the pin.

A stowable motorized skateboard comprising a first board section, a second board section, a power supply section, and support bars. The first board section includes a locking mechanism and first support anchors. The second board section includes a controller, a motor, second support anchors, and power supply anchors. The power supply section is between the first and second board sections, encasing a battery electrically coupled to the controller and the motor, and including a catch receiving the locking mechanism. The power supply section further receives the power supply anchors. The support bars extend from the first board section to the second board section and receive the first support anchors and the second support anchors.

A skateboard truck that includes an inertia drive attached to a wheel. The inertia drive causes an inertial mass (i.e. flywheel) to turn at a higher speed then the wheel. During “pumping” of the skateboard the wheels accelerate and an inertia drive helps propel the skateboard given its inertia combined with the wheel inertia. The inertia drive may be configured to maintain skateboard stability at high speeds.
