Precise compatibility with M625 and mid drive motors for excellent fitment and smooth power transmission. High-strength aluminum alloy construction for durability and performance. Resists deformation under high torque output of 1000W mid motors, enhancing handling and acceleration. Special tooth profile designed for e-bike use, improving chain retention and reducing chain drop. Optimized tooth shape for single-chainring e-bike setups, providing smoother and quieter engagement with the chain. This aluminum alloy chainring is specially designed for M625 and mid drive motors, ensuring excellent fitment and smooth power transmission. It is an ideal upgrade or replacement sprocket for high‑power 1000W electric bikes. The chainring is made from aluminum alloy, featuring a good balance of strength and light weight. It resists deformation under the high torque output of 1000W mid motors and helps reduce the overall weight of the drivetrain for better handling and acceleration. The specially engineered tooth profile improves chain retention and reduces the chance of chain drop during strong acceleration or off‑road riding. The optimized tooth shape is suitable for single‑chainring e‑bike setups and provides smoother, quieter engagement with the chain.
