ABSTRACT:
The present invention relates to a scooter that is self propelled with a uniquely designed spring winding propulsion system. Using a system of interrelated gears and sprockets, the propulsion system is automatically rewound as a user manually propels the scooter. Accordingly, when the propulsion system is sufficiently rewound, a release button transfers energy contained within the wound springs to a rear wheel thereby automatically propelling the scooter.
