ABSTRACT:
The present invention provides a rider-propelled vehicle that includes a frame capable of supporting a rider, an eccentrically-mounted front wheel, and a concentrically-mounted rear wheel. In one embodiment, the rider propels the vehicle using the cyclic motion of the eccentric front wheel, and a driving mechanism is not provided for the rear wheel. Another embodiment of the present invention provides a frame for a rider-propelled vehicle. The frame includes a head tube, a top tube connected to the head tube and extending to one side of an axle for a rear wheel, a bottom tube connected to the head tube below the top tube and extending to another side of the axle for the rear wheel, and a cross tube extending between the top tube and bottom tube in front of the rear wheel. In this embodiment, the top tube and the bottom tube extend along side one another at the same height from the location for connecting the axle for the rear wheel to a predetermined location. This portion of the top and bottom tubes allows for connection with a deck capable of accommodating a rider.
