An electric bicycle driving apparatus is disclosed. The apparatus includes a speed change mode operator to output a first speed change mode signal or second speed change mode signal, a controller to receive the first speed change mode signal or second speed change mode signal and output a first control signal corresponding to the first speed change mode signal or a second control signal corresponding to the second speed change mode signal, a motor driver to, when the first speed change mode signal is output, receive the first control signal and output a first motor driving signal to drive a motor in a first speed change mode, and, when the second speed change mode signal is output, receive the second control signal and output a second motor driving signal to drive the motor in a second speed change mode, and a relay to selectively receive a relay switching enable signal.
