Abstract: An electric shift operating device is basically provided with a base member, a first operating member, a clicking mechanism, a signal generating arrangement and a controller. The base member is configured to be attached to a bicycle. The first operating member is movably supported on the base member from a rest position to an operated position. The clicking mechanism is operated by the first operating member to produce a haptic feedback response upon the first operating member reaching the first operated position. The signal generating arrangement generates a first shift start signal prior to or upon the first operating member reaching the first operated position. The controller controls a gear position of the electric gear changing device. The controller receives the first shift start signal and operates the electric gear changing device towards a target gear position upon receiving the first shift start signal.

Abstract: A drive train comprises a sprocket arrangement and a force-transmission coefficient. The sprocket arrangement includes a plurality of rear sprockets and a plurality of gear ratios respectively corresponding to the plurality of rear sprockets. The plurality of gear ratios includes a largest gear ratio and a smallest gear ratio. The sprocket arrangement includes at least one individual sprocket-space provided between two adjacent rear sprockets among the plurality of rear sprockets. The force-transmission coefficient is obtained by dividing a total gear range quotient by a total number of the at least one individual sprocket-space. The force-transmission coefficient is equal to or larger than 0.97 and is equal to or smaller than 1.36. The total gear range quotient is obtained by dividing the largest gear ratio by the smallest gear ratio.
