The propulsion enhancement is provided by a transmission device which is mounted adjacent at least one wheel of the skateboard. The transmission device includes a spring for storing energy during one mode of operation and releasing energy during a second mode. A lever controlled by the foot of the user shifts between the two modes. The transmission may also include a retarding force for controlling the speed of the skateboard. Various devices, e.g., lights, sound, smoke and hubcaps, are included which add to the attractiveness of the skateboard.
