Abstract

A bicycle gear changing apparatus is basically provided with an upshifting input, a downshifting input and a controller. The controller is operatively coupled to the upshifting input and the downshifting input to receive upshift signals and downshift signals. The controller outputs control signals to control a first gear changing device and a second gear changing device in accordance with a synchro-downshift route and a synchro-upshift route that is different from the synchro-downshift route, in response to receiving the upshift signals and the downshift signals.
