Abstract: A hub motor for a single-wheel electric vehicle. The motor includes an outer rotor which encloses a stator that in turn encloses an interior chamber within the hub motor that may be used to hold an electronic controller. One or more end caps may suspend a mounting board within the interior chamber, and the exterior of the one or more end caps connects the apparatus to the electric vehicle's chassis. The additional capacity provided by the interior chamber allows the electric vehicle to hold more battery capacity, thereby extending the range of the electric vehicle between recharges.

Abstract: 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.
