Disclosed is an electric-bicycle drying apparatus. The apparatus includes a speed-change mode operator to output a low-speed or high-speed mode signal, a controller to output a first or second control signal corresponding to the low-speed or high-speed mode signal, a first motor driver to output a first motor-driving signal to drive a motor in a low-speed mode in response to the low-speed mode signal, a second motor driver to output a second motor-driving signal to drive the motor in a high-speed mode in response to the high-speed mode signal, a motor-drive-load booster to boost load of the second motor-driving signal using battery power under control of the controller in response to the high-speed mode signal, and a motor speed-change switching unit to selectively receive a switching enable signal from the controller so as to be turned on to provide the second motor-driving signal having the boosted load to the motor.
