In this study, new Continuously Variable Transmission(CVT) system which is adaptable to a small size electric vehicle is proposed available to gradient response CVT. New pulleys consist of springs adapted driving pulley and driven pulley. At the moment a small electric vehicle drive a slope, new system respond to a gradient as overcoming tensional force of springs. We made prototype of gradient response CVT to test parts performance. As a result of test, belt pitch diameter varied for high torque direction at the gradient.
