ABSTRACT:
An apparatus wherein a tricycle arrangement mounts its associated seat overlying a rear axle, wherein the rear axle mounts a plurality of spaced wheels, with a forward wheel medially positioned relative to the rear wheels. A sprocket and chain drive directs rotative energy to rotatably drive the rear wheels. A rear stabilizer wheel is positioned rearwardly of the rear wheels. The stabilizer wheel is normally spaced above a ground support surface in a first position and is in contact with the ground support surface in a second position when the forward wheel is spaced above the ground and pivoted about the rear drive wheels. A counter-weight structure is optionally utilized to enhance such pivotment.
