An electric bicycle assembly for propelling a bicycle includes a bicycle that includes a first chain sprocket and pedals coupled to the first chain sprocket for rotating the first chain sprocket to propel the bicycle. A second chain sprocket is coupled to the first chain sprocket such that the second chain sprocket is rotated when the first chain sprocket is rotated. A generator is coupled to the bicycle and the generator is rotated to generate electrical energy when the pedals are pedaled. A motor is coupled to the bicycle and the motor is in mechanical communication with the rear wheel. The motor rotates the rear wheel when the motor is turned on for propelling the bicycle.
