In this study new Continuously Variable Transmission system which is adaptable to a small size electric vehicle is proposed available to gradient response Continuously Variable Transmission. 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 Continuously Variable Transmission to test travelling performance. In the travelling performance test, the small electric vehicle with gradient response Continuously Variable Transmission get improved perfomance than the small electric vehicle with reduction gear.
