Abstract
A powered roller skate apparatus includes a motor supported on the back of a user, with a flexible drive extending from the motor to a front wheel truck for a standard roller skate. The wheel truck is interchangeable with that of any standard roller skate, and only one bolt need be removed and replaced to effect the change. Instead of an internal shaft to drive the one driven wheel, the wheel drive system includes a hub adjacent to the outside of the wheel, and a series of prongs extend from the hub directly into the side of the urethane wheel. Gear reduction from the motor is achieved through two angle drive gear boxes, one at each end of the flexible drive, which may include different-sized gears for the reduction, at the same time this enabling the flexible drive to be oriented generally upright between the skate and the motor. The motor is supported on a back pack type frame, with a pair of handle bars extending forwardly at the hips of the user, including a throttle control and a rope start handle mounted on these handle bars.
