ABSTRACT:
A variable ratio bicycle chain drive uses a variable radius sprocket assembly having a number of chain engagement elements mounted to worm gears for movement along radial channels. Radius changer gears, such as star wheels, are mounted on at least some worm gears to cause them to rotate upon contact with teeth of a switch. Drive gears are connected to each other by a center gear and connected to the worm gears to ensure that all worm gears rotate in unison.
