Abstract
A human-powered, ride-on vehicle, includes a main longitudinal frame member having a steering/drive mechanism mounted thereon for oscillating movement; a driven rear wheel having an axle, a rear sprocket operatively fixed to the rear wheel for coastable engagement therewith; a pair of spaced apart, steerable front wheel located adjacent the other end of the main longitudinal frame member and operatively connected to the steering/drive mechanism; wherein, the steering/drive mechanism include: a teeter arm mounted to the main longitudinal frame member intermediate the ends thereof for pivoting movement in a fore direction and an aft direction; a drive mechanism including first and second drive linkages, wherein the first drive linkage provides a motive force to the driven rear wheel during a first power stroke and the second drive linkage provides a motive force to the driven rear wheel during a second power stroke, and wherein, for equal movement of the teeter arm in the for and aft directions, the motive force of the first powers strokes is between about one to three times that of the second power stroke.
