The automatic gear shifting system for two-wheel electric vehicles includes a detection unit for detecting the status of operation of the two-wheel electric vehicle, a processing unit connected with the detection unit for receiving, analyzing and filtering the detected signals so as to generate a speed-changing signal that is correspondent to the detected signal, and a driving device having a low-power motor unit and control member with multiple nodes. The driving device is connected to the operation cable of the speed changing device. The driving device receives the signals of changing speed so as to change the gears according to the signals of changing speed. A motor unit located at the mediate portion of the vehicle is coupled to the processing unit and the front chainwheel.
