A bicycle is provided to allow a rider to select riding conditions by keeping the original position of a support frame or folding the support frame toward a down frame. A bicycle includes a down frame(20), a support frame(22), a head housing(24), a fixing frame(21), and a drive unit(30). The down frame extends toward a front upper part of the bicycle. The support frame is vertically connected to a lower end of the down frame and has a saddle(23). The head housing is coupled to an upper end of the down frame and has a front fork rotatably coupled. The fixing frame horizontally extends from a lower end of the down frame to fix a rear wheel(29). The drive unit is disposed at a position, at which the down frame, the support frame and the fixing frame are fixed to each other, to transmit a drive force to the rear wheel. |
