A lift kit assembly includes a pair of axle cup bracket portions each adapted to accept an axle end and adjustably mount to a side rail or frame of a motorized skateboard on either side of a wheel whereby the axle of a motorized skateboard may be lowered or raised as desired by a user.

Apparatus and systems are provided that enhance the use of a one wheel skateboard. Some of the apparatus described provide lateral surfaces that engage outer portions of a user's feet. Other apparatus facilitate the engagement of common snowboard bindings to a one wheel skateboard, thereby widening the spectrum of tricks that can be performed.

A self-propelled, one-wheeled vehicle may include a suspension system configured to dampen up and down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems include a shock absorber, a rocker, a pushrod, bell cranks, and/or a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.

A sliding balance board has an eccentrically mounted center wheel as a pivotable central balancing member, a wheel with one-way sprag clutch bearings mounted near the left end of the board and a wheel with one-way sprag clutch bearings mounted near the right end of the board. A user balances himself/herself on the board, and yet slides the board to the left and right, back and forth by shifting his/her weight left and right, synchronized to the rocking motion of the eccentrically mounted center wheel.

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 recreational device including a single wheel having a rim with a track and a tire coupled to the rim. The recreational device further includes a central hub assembly positioned within the wheel and movably coupled to the track of the rim such that the central hub assembly is rotatable in the track about an axis of rotation of the wheel. The recreational device further includes a support plate coupled to the central hub assembly and configured to support a human foot, and a guard plate coupled to the central hub assembly. The recreational device is configured such that rotational movement of the central hub assembly is independent from rotational movement of the wheel.
