Abstract: A wheelchair having torsion-acting shock absorbers from which cantilevered swing arms connected to drive wheels are connected is disclosed. The wheelchair incorporates a compact, collapsible power scooter that attaches to the wheelchair and presents a pair of handlebars having an accelerator and a brake, thus enabling the rider to propel him or herself by a power drive train rather than by hand.

Abstract: A motorcycle for supporting a seated rider straddling a saddle atop a frame and above a motor has an improved torsion acting shock absorbing mount for the cantilevered shock absorbing support of at least one of the motorcycle wheels from the frame. In a preferred embodiment, the torsion acting shock absorber includes a square sectioned metal tube, a correspondingly square sectioned metal shaft, and confined compressible rubber rods acting there between. A shock absorbing suspension is disclosed for both the front steered wheel and the rear driven wheel.
