The invention discloses a bicycle frame manufacturing method and a bicycle frame. A front beam tube and a rear fork tube of the bicycle frame are each formed by splicing at least two split parts, and after the split parts are disassembled, inner cavities of the front beam tube and the rear fork tube can be exposed from one side; when the bicycle frame is manufactured, the method comprises the following steps:(1) the shapes of the split parts are designed, specifically, the shapes of the split parts are designed according to the shape of the bicycle frame; (2) part forming is conducted, specifically, mold opening is conducted according to the designed shapes of the split parts; then, given alloy raw materials are added into corresponding molds according to the proportion, and all the split parts are manufactured; 3)splicing is conducted, specifically, the split parts which are assembled with each other are assembled and formed through strong glue, and then the two split parts which are assembled with each other are fastened together through bolts or screws, and (4) curing is conducted, specifically, curing is conducted on the strong glue. The method has the advantages that the process is simpler, and the overall strength of the frame is higher.
