Abstract: A motor vehicle with an on-board propelling power source and operator control functions for steering, increasing and decreasing the vehicles rate of motion. The vehicle includes a chassis with an operator seat for receiving a human operator; a front wheel that can be laterally directed by the operator so the operator can steer the vehicle; a front wheel which is connected to an electronic motor for propelling the vehicle; a drive-gear train assembly for transferring the rotational power of the electronic motor to rotational power of the front wheel; a pair of rear wheels spaced laterally relative to each other for supporting and assisting in maneuvering the vehicle; and a pair of front stabilizing wheels spaced laterally from the front wheel with the front wheel intermediate to the front stabilizing wheels. The steering mechanism, drive-gear train assembly, and electronic motor are attached to a steering shaft and rotate with the steering shaft.
