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 stand-up wheeled vehicle may include an electrically powered wheel and a deck configured to limit a maximum value of an angle of declination of the deck in a forward direction of travel, for example, to less than about 20 degrees, 15 degrees, 10 degrees, or 8 degrees. The deck may be asymmetric, such that a length of a first portion of the deck between the wheel and a first end of the deck is greater than a length of a second portion of the deck between the wheel and a second end of the deck. The deck may include a first surface, an opposing second surface, and a chassis disposed in the second surface. The chassis may have a cavity formed therein configured to receive a stand-up wheeled vehicle. A coupling mechanism may be utilized to removably retain the stand-up wheeled vehicle in the cavity of the chassis.

A personal transport includes a deck configured for supporting a rider in a standing position. At least one wheel assembly is mounted on a bottom surface of the deck, the, or each, wheel assembly having at least one wheel so that the deck can travel over a substrate. An operator handle is substantially rigidly mounted on a rear end of the deck and extends rearwardly from the deck so that an operator, standing on the substrate, can grasp the operator handle and push the apparatus along the substrate, or tilt the apparatus relative to the substrate, while the rider is supported on the deck. A rider handle mounted on one of the deck and the operator handle and positioned so that the rider can grasp the rider handle for balance while supported by the deck.

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 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.

An electric skateboard includes a frame assembly has a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame has a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned at least partially in the enclosure. Front and a rear truck are mounted to the bottom of the deck. At least one of the first and front and rear trunks are 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 mounted on a rear end of the deck. Upper and lower control arms share a single shaft.
