The vehicle may be a stroller, a toy vehicle, a scooter, a wheelchair, a cart, a dolly, etc., and it can have more than one caster.

Abstract: A Tread Wheel Frame System drives a human-powered cycle by means of a tread wheel driving a tread of a drive wheel of a cycle rather than driving a drive wheel hub, as conventional cycles do. Most of the driving mechanism, including the tread wheel, a speed ratio mechanism, shifting means, and a power unit device, are safely located above the level of a cycle s axles where they are less likely to encounter accidental impact. The tread wheel with the power unit device also does the braking, which eliminates the need for caliper brakes or hub brakes. Accordingly, a drive wheel is lighter, without the need for a heavy hub, or a heavy rim to withstand the wear and heat of friction of caliper brakes. The tread wheel frame is uniquely designed and engineered to be light, yet strong where needed.
