About CSC

Since 2011, CSC has been committed to the R&D, production and sales of carbon fiber bicycle wheelsets and e-bike conversion kits. We focus on the manufacturing and assembly of high-performance carbon fiber wheels, reliable bicycle motors and safe e-bike batteries, with strict quality control throughout the whole production process.



As a self-operated manufacturer integrating independent production and direct sales, we have cut out redundant middlemen, greatly optimized our cost structure, and established a direct communication channel with global customers. This allows us to capture real user feedback efficiently, improve our products continuously and offer more competitive pricing.



We always adhere to the principle of balancing quality and affordability. Our mission is to provide cycling enthusiasts and business partners with durable, high-performance and cost-effective products, helping more riders enjoy a smarter and smoother riding experience.
