Method of molding composite bicycle frames
 A method of molding a composite bicycle frame that includes the steps of curing a pair of seat stays and chain stays respectively and then connecting with the front triangle. Non-foaming dilatable materials are provided at suitable locations in the mold, such as the steering support cavity, the pedal support cavity, the seat stay butting cavity and the chain stay butting cavity. By heating the mold once, the seat stays and chain stays will secure with the front triangle and the front triangle can be cured at the same time to simplify the mold and the process.
