Abstract: A manufacturing method of a thermoplastic composite bicycle frame comprises a shell forming step: turning thermoplastic composite laminates into shells being assemblable by compression molding, wherein each shell has a cavity surrounded by the shell, at least one straight segment and at least one curved segment connected with each other, the straight segments are aligned with one another, the curved segments are aligned with one another, each straight segment has a straight connecting edge, and each curved segment has a curved connecting edge; a shell assembling step: assembling the shells to make the straight connecting edges overlapped with one another and to make the curved connecting edges butt jointed with one another; and a hot pressing step: turning the straight connecting edges and the curved connecting edges into fusion areas by heating and compressing so as to connect the shells as a bicycle frame component.
