An exercise bicycle is composed of a base, a motor, a seat plate, a plurality of resilient elements, a support unit, a seat, a handle, two pedals, and a drive device. The motor is mounted on the base and provided with an eccentric rod fastened with a shaft of the motor such that the eccentric rod is capable of disturbing the seat plate to vibrate horizontally at the time when the motor is in operation. The horizontal vibration of the seat plate is imparted via the support unit to the seat, the handle and the pedals for massaging the hips, the back, and the hands of a user of the exercise bicycle, who is engaged in a leg exercise.
