AI Technical Summary

Problems solved by technology

[0003] Existing wooden bicycles use wooden frames, but still need metal sprockets and chains as transmission parts, but the metal transmission parts cannot be colored at will, which is not conducive to forming an overall color pattern with the wooden frame, and is easy to rust and insulate The performance is poor and the manufacturing cost is high, so it needs to be improved
