A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.

A system for control of a mobility device comprising a controller for analyzing data from at least one sensor on the mobility device, wherein the data is used to determine the gait of user. The gait data is then used to provide motion command to an electric motor on the mobility device.

An exercise device is described. An exercise device includes a body, the body having a top, a bottom, a first end located at one edge of the body, a second end located at an opposite edge of the body, and first and second sides extending between the first and second ends; one or more wheels; and an energy storage device applying resistive and restoring force to the one or more wheels. Optionally, a shaft can be present that rotationally locks two or more of the wheels.

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.

An electric roller skate in the present invention includes a shoe body, a roller frame, a driver, a rotation speed detection device, and a controller. The controller receives rotation speed information of the rotation speed detection device and accordingly controls the driver to start to drive the rollers to rotate. The present invention further provides a control method for the electric roller skate described above. The controller is capable of controlling the driver to start to drive the electric roller skate to slide according to the detected rotation speed information. Through the above arrangement, the solution can help a user to skate in a more labor-saving manner and reduce fatigue of the user. Meanwhile, the driver is started in a mode closer to a conventional sliding mode, is higher in convenience and intelligence, reduces use difficulty and makes user experience better.

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.
