Abstract
A tricycle or other similar vehicle has an improved drive mechanism utilizing a pair of pedals, each of which has an associated cam and cam follower such that as the pedals are reciprocated the cam followers ride along the cams to rotate a drive axle and propel the vehicle. A shift mechanism permits realignment of the cam followers and cams to thereby change the direction of movement of the vehicle as the pedals are reciprocated. The drive mechanism and shift may be mounted to the rear wheels or, in an alternate embodiment, mounted to the front wheel of the vehicle.
