ABSTRACT:
A belt drive for bicycles with a drive pulley rotated by the pedals of the bicycle and a driven pulley for driving the rear wheels of the bicycle. A V-belt connects the pulleys. Each pulley is made in sections with each section being an arc of a circle. These sections in collapsed position form a circle. The sections of each pulley may be moved outward to provide a larger diameter. A plate rotates in frictional contact with each pulley. To change the gear ratio a brake is applied against the friction plate to cause relative motion between the pulley and the complimentary friction plate.
