The invention discloses a high-strength folding bicycle. A hollow bicycle head rod, a rear wheel frame and a first shell are integrally formed. A first part is lengthened to be used for fixing a bicycle head assembly and a rear wheel assembly. A seat rod, a front wheel hollow front wheel sleeve rod and a second shell are integrally formed. A second part is lengthened to be used for fixing a front wheel assembly and a saddle assembly. After the parts are integrally formed, the connection among the first part, the second part and all the parts is firmer, and the connected parts are not prone to fracture. The structural strength of a bicycle frame is high, the bicycle is not prone to deformation or fracture on account of physical impact in the using process, and the connection firmness between the other assemblies and the middle bicycle frame of the bicycle can be effectively enhanced.
