Abstract Motorized skates which are driven by a compact motor located on the skate frame, power for which is supplied by battery means. On/off and speed switches are readily accessible and may be attached to the operator by a belt. In one preferred embodiment, axially mounted wheels are used and the structure resembles that of conventional skates. In another preferred embodiment, an endless treaded track is used in place of the wheels.
