The steering column is connected between a front wheel and a handle. One end of the first frame is coupled to the steering column so as to rotate in a first rotation axis direction which is parallel to the steering column and a second rotation axis direction meeting the steering column at right angle. The second frame, wherein a drive sprocket is connected to an end and a saddle is installed on the other end, is pivotally coupled with the other end of the fist frame. The third frame is coupled with a rear wheel on an end and the second frame on the other.;COPYRIGHT KIPO 2011
