PURPOSE: A suspension for a bicycle is provided to immediately repair a tire by replacing the tire without the separation of the suspension from a wheel hub. CONSTITUTION: A suspension for a bicycle comprises a support bar(100), a connection unit(400), an upper cylinder(600), an end member(1100), a piston(1300), an auxiliary buffer spring(1200), a middle coupling unit(800), a spring cap(700), an upper buffer spring(900), a lower cylinder(1400), and a lower buffer spring(1500). The support bar couples a handle stem of a bicycle to a chassis frame. The connection unit is extended from the support bar. The upper cylinder is downward extended from the connection unit. The end member has an oil hole. The auxiliary buffer cylinder is elastically supported to the inner space of the upper cylinder. The middle coupling unit is vertically reciprocated by the upper cylinder. The spring cap is coupled to the top edge of the upper cylinder. The upper buffer spring is elastically supported between the bottom of the spring cap and the top of the middle coupling unit. The lower cylinder is filled with oil. The lower buffer spring is installed in the inner space of the lower cylinder.
