摘要： A method for manufacturing a composite bicycle frame adapts stepped forming. The seat stays combined with the seat support means which are connected to parts of the top tube and seat tube, and the chain stays combined with the pedal support means which are connected to parts of the down tube and seat tube, are formed respectively. The seat stays connect to the chain stays by inserting a pair of rear wheel dropouts therebetween, to form substantially a pair of rear triangles of the bicycle frame. The seat tube and the steering support means connected to the top tube and down tube are laid up respectively. The cured rear triangles connect to uncured seat tube and steering support means associated with top tube and down tube, wherein the top tube, down tube, and seat tube form a front triangle. The front triangle is cured such that manufacturing of the whole bicycle frame is completed.
