Abstract: A third braking system for an electric motorcycle includes a circuiting apparatus and a mechanism. By depressing an electric-braking button on a switch part of a handle set, a braking signal will be generated and be sent to a signal transformer via an input device of the circuiting apparatus. The signal transformer transforms the braking signal into a digital signal, and then the digital signal is sent to a CPU. After processing the digital signal and detecting the voltage level at a variable resistor, the CPU stops the transmission of driving signals to a driving circuitry for disabling the operation of a speed-control handler of the mechanism, and the CPU also generates a reverse electric potential corresponding to the detected voltage level. The reverse electric potential is then applied to a DC motor via a braking circuitry, for reducing rotation speed of the DC motor to stop the motorcycle. To relieve the braking, the speed-control handler is rotated back to an original state.
