ABSTRACT:
A demountable wheel assembly for a vehicle which comprises an axle-retained wheel hub and a wheel, on which a tire is mounted, which are quickly releasably connectable to, or separable from each other, even by the weak, the aged, and the handicapped. Guide pins on the wheel hub align the tire mounted-wheel, while exposed permanent magnets partially embedded in the wheel hub draw and hold the wheel, thereby freeing the hands. Headless bolts are driven by a brace-shaped driver through threaded bolt nuts that are partially embedded in the wheel; through threaded, tapered extensions behind the nuts; and into threaded, tapered cavities in the wheel hub. Overtightening of the bolts is prevented by the short-span of the bolt driver.
