In this study, new CVT system adapted for variable radius pulley is proposed to be available for pulley of CVT. Variable radius pulley consists of two disk and sliding pins joined by these disks. On account of phase difference of two disks, sliding pins move to radial direction and pitch diameter is varied. Therefore, change speed is accomplished by varying pitch diameter of pulley. CVT adapted for variable radius pulley is also performed with dynamometer test and axial distance variation. As a experimental result variable radius pulley can be alternative such as bicycle.
