Abstract
This device is an improved wheelie skateboard having a substantially flat horizontal portion and an integrally connected inclined rear kicktail portion. The front end of the horizontal portion has a pair of conventional skateboard wheels on a truck having a pivot bolt connected to the axle at the rear of the axle, and capable of swivelling in a conventional manner. The inclined kicktail portion has a pair of conventional skateboard wheels having a pivot bolt forward of the axle and, likewise, capable of swivelling in a normal manner. The central pair of wheels is so mounted as to be incapable of swivelling, either because of the nut on the pivot bolt (of a conventional truck), which is to the rear of the axle, is so tightened, or because a horizontal arm portion on a non-conventional truck extends from the truck rearwardly of the axle to forwardly thereof, so that such pair of wheels may tilt but may not swivel.
