ABSTRACT:
A power supplying accessory that can readily be retrofitted to an unpowered skateboard includes a leaf spring having a front end and a rear end; the front end including holes sized and spaced to fit on the threaded fasteners that attach the rear truck to the body of the skateboard; the leaf spring being secured between the rear truck and the body of the skateboard; the rear end of the leaf spring being attached to a drive assembly that includes an internal combustion engine, a drive wheel and a speed reducer; the leaf spring, in its unloaded condition, holding the drive wheel below an imaginary ground plane tangent to both the front and rear wheel of the skateboard, so that when the skateboard is loaded, the leaf spring preloads the drive wheel against the ground while the use of the rear truck of the skateboard permits the skateboard to retain its steering characteristics, thereby making it easy to learn to use.
