The utility model relates to a frame of a two-wheeled maneuvering large-pedal motorcycle. The shock absorber comprises a vertical pipe, an upper supporting pipe, a lower supporting pipe, a side pipe,a front shock absorption supporting pipe, a rear shock absorption supporting pipe, a tail connecting pipe and a tail supporting pipe. Upper supporting pipes are symmetrically arranged on the two sidesof the upper portion of the vertical pipe. Lower supporting pipes are symmetrically arranged on the two sides of the lower portion of the vertical pipe. The lower supporting pipe is of a U-shaped tubular structure with U-shaped arms on the two sides inclining outwards. The bent part of the U-shaped arm at the front part of each lower supporting pipe is connected with a side pipe; the side pipe isof an upwards-inclined tubular structure, the lower portion of the front end of the side pipe is fixedly connected with the lower supporting pipe, the middle of the side pipe is in lap joint with thetail end of a U-shaped arm on the rear portion of the lower supporting pipe and welded to the lower supporting pipe through a reinforcing plate III, and the pipe wall between the front end of the side pipe and the middle of the side pipe is further fixedly connected with the tail end of the upper supporting pipe. The bicycle frame is high in structural strength, good in riding comfort and few inwelding parts; and the effective load of the whole vehicle is increased, parts on the pipe are reduced, and welding parts are reduced.
