The embodiment of the invention is suitable for the technical field of bicycle highways and provides a convenient-to-weld high-speed steel box girder for a bicycle. The steel box girder comprises a box body, at least one through hole extending along the length direction of the box body is formed in the box body, and at least one manhole connected with the through hole is formed in the top of the box body. According to the convenient-to-weld high-speed steel box girder, when two steel box girders are oppositely welded or the steel box girder and a steel cap girder are oppositely welded, a constructor can enter the through hole in the box body from the manhole formed in the top of the box body and can move to the end of the box body by virtue of the through hole, so that internal welding can be conveniently carried out at the end where the two steel box girders are mutually butted or the steel box girder and the steel cap girder are mutually butted, thereby improving the welding strength and the welding firmnes
