The object of the present invention is to provide a new and improved bicycle arranged to permit a rider to conveniently change the gearing from a high speed to a low speed, or vice versa, and manipulate the bell and brake by means of electricity and to insure against being run into during the night by displaying a danger-signal from the rear.
