Abstract
A bicycle wheel has a wheel frame. The wheel frame is a hollow and annular frame and is composited by multiple equally sized wheel bars. Each one of the wheel bars has two halves connected to each other to form the wheel bar, and each one of the two halves being made by laminating, heating and forming a thermoplastic prepreg. The equally sized wheel bars are connected to each other to form the bicycle wheel.

A method of manufacturing a bicycle wheel comprising:
- a preparing step comprising
- preparing a thermoplastic prepreg, multiple modular molds, a cutting device, a heating device, a molding device, and at least one processing machine;
- disassembling the bicycle wheel into several parts according to shape and size of each part;
- and
- forming the modular molds to having outer dimensions and structures corresponding to the parts of the bicycle wheel;
- a module-lamination step comprising
