Abstract
An elliptical drive system for stepper type bikes that needs no chains or sliders for its operation. Its quadrilateral linkage minimizes the vertical motion of the user's feet while guiding the feet in a natural motion that resembles walking. The elliptical drive system is designed to give the stepper bike high ground clearance for traveling on rough terrain. Adjustment apertures on the linkage arms allow the user to adjust the length of linkage arms according to the user's leg length and overall size.
