An ultrasonic type bicycle driving motor includes an ultrasonic type rotation driving device to replace the silicon steel plates, windings and magnet that are used in the conventional bicycle driving motor. A rotary manual control is provided on the handlebar of the bicycle to allow a rider to control the voltage and current supplied from a battery set to the motor, preferably in a manner similar to the handle throttle control adapted in a motorcycle, so that the rider may regulate the output torque and rotational speed of the motor as desired. The disclosed bicycle driving motor does not change the outside configuration of the bicycle and does not interfere with operation of the bicycle. Further, the disclosed bicycle driving motor is easy to install and suitable for bicycles of almost all designs. Maintenance is simple. The disclosed bicycle driving motor may be either mounted on the front wheel or the rear wheel, or on both the front and rear wheels of the bicycle.
