A connecting method of a wheel rim of a bicycle includes the following steps: forming a wheel rim, inserting an inner connecting member between two abutment ends of the wheel rim, connecting the two abutment ends, heating, packing, permeating, and returning. Thus, the structural strength of the wheel rim is enhanced, thereby increasing the lifetime of the wheel rim. In addition, the connecting seam of the two abutment ends will not form a protruding rough bur, so that it is unnecessary to perform a secondary working process to grind the surface of the connecting seam of the two abutment ends, thereby simplifying the working process of the wheel rim, and thereby decreasing costs of fabrication.
