1. A method of shifting a bicycle with an electronic gear shifting system, wherein the electronic gear shifting system comprises
a first shift unit including a first brake support, a first brake lever pivotally mounted to the first brake support and a first switch mechanism mounted to the first brake support;
a second shift unit including a second brake support, a second brake lever pivotally mounted to the second brake support and a second switch mechanism mounted to the second brake support;
a control unit in communication with and responsive to first and second signals from the first and second switch mechanisms, respectively;
a front gear shift mechanism; and
a rear gear shift mechanism in communication with and responsive to command signals from the control unit, comprising:
actuating only the first switch mechanism to perform an upshift of rear gear shift mechanism; and
actuating only the second switch mechanism to perform a downshift of the rear gear shift mechanism,
wherein the front gear shift mechanism is nonresponsive to the actuation of only the first switch mechanism and the actuation of only the second switch mechanism.
