1. Designed specifically for e-bikes: The precision of each component is controlled within 1μm, perfectly meeting the requirements of high-strength e-bike systems. The chain runs smoothly, performs excellently, and features a quick-release design for easy assembly and disassembly.
2. Carbon steel material: To meet the high tensile strength requirements of e-bike drive systems, the chain is precision-manufactured from special carbon steel. Tested by the internationally renowned TÜV, the chain can withstand tensile forces up to 2336 lbs.
3. High-quality protection: The chain surface undergoes advanced high-temperature treatment to ensure stable and reliable performance. This prevents corrosion in harsh environments and effectively reduces wear and natural oxidation under harsh riding conditions such as mud and gravel.
4. Special coating: Reduces the coefficient of friction, decreases operating noise, protects other components in the drive system, and extends the lifespan of the e-bike.
5. Quality Assurance: Tested by internationally recognized TUV / Meets national standard: EN-ISO 4210-2004
After-sales Service: If the SUMC electric rib chain breaks within 6000 kilometers, contact us for a free replacement chain (chain maintenance every 500 kilometers).
