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.

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.

Apparatus and method for winding for winding enamel wires into a motor stator which provides for precisely positioning motor stators to be wound, so that the scraping of the outer coating of enamel wires by the wire slots of motor stators can be avoided during winding operation of motor stators. Furthermore, the improved multi-phase synchronous winding apparatus for motor stators is capable of immediately detecting the damage of the outer coating of the enamel wires during winding operation of motor stators so as to avoid the waste of enamel wires and working times. The improved multi-phase synchronous winding apparatus for motor stators also prevents the enamel wires from disengaging by the use of a tension control device during winding operations of motor stators.
