Abstract: A motorized stationary bike is provided for lower body rehabilitation. The motorized stationary bike has the same general appearance as an ordinary bike. Furthermore, it comprises a motor, a drive shaft, a coupler, a worm gear, and a toothed gear where the motor, the drive shaft, the coupler, and the worm gear are axially aligned one to another, and are horizontally disposed on the bike frame. The motor is connected to the drive shaft, and the drive shaft is coupled to the worm gear by the coupler. The worm gear is engaged to the toothed gear. The motor is coupled to an electrical energy source such that when the motor is turned on, the worm gear drives the toothed gear, which causes each of the step pedal supporting arms and the respective step pedal to turn.
