Abstract
A hand propelled tricycle has a hand-operated crank assembly mounted to an upper end of a front fork stem coupled to a front wheel supported by the fork. The fork is straight without caster and a set of springs attached between the fork and a tricycle frame provides centering of the front wheel. A pair of spaced-apart wheels is mounted to an axle at the rear of the frame.
