Abstract
An electronic shifter for shifting a bicycle gear mechanism between a plurality of gears and using a relative shifting method. The shifter includes a stationary member mountable on a handlebar of the bicycle and a rotatable member rotatable with respect to the stationary member to define predetermined positions of the members with respect to each other. An electrical switch is operatively connected to the rotating member for generating a shift signal in response to the rotating member rotating from one predetermined position to another predetermined position.
