Eco-Vehicle Corporation's patent pending products result in a superior Linear drive system. The outcomes perfectly match between the human natural rectilinear motions & strengths and the movement of the vehicle because our products provide superior means to integrate the human natural linear motion, strength, and energy into engineered systems to power the vehicle with minimum energy & friction loss and maximum mechanical advantage & efficiency.
