ABSTRACT:
The skateboard device includes a board of extended surface area adapted to support a skateboard rider, a pair of spaced front and rear wheels connected to the underside of the board, a relatively massive rotor disposed for rotation in a housing connected to the underside of the board adjacent either the rear or front wheels, preferably the rear wheels, and a gear assembly in the housing interconnecting the rotor and wheels which are adjacent thereto. With this arrangement, when the skateboard is pushed to start it up, the inertia of the rotor is overcome as energy is transferred from the geared wheels through the gear assembly to the rotor to cause it to rotate in the housing. When a sufficient or desired speed for the skateboard is reached, the skateboarder climbs aboard and glides along, the stored energy in the rotational momentum of the rotor being transferred back to the interconnected geared wheels, causing a smoother, longer ride than is attainable without the rotor. The front wheels may pivot and the rear wheels may independently operate through separate axles. A shock-absorbing skid member can be attached to the housing to protect the gear assembly.
