This flywheel pinion is suitable for users who modify or upgrade bicycles or electric vehicles due to its specific specifications and design. The modified bicycle or electric vehicle has better performance.
Premium and stable and exquisite workmanship, strong and durable, can be used for a long time because of its high strength and hardness.
Suitable for single-speed bicycles, electric bicycles, and folding bicycles. The fewer teeth, the faster the speed.
Unlike fixed flywheels, when installing live flywheels, the chain should not be too tight after installation. Too tight will cause the chain to stall when rewinding. After installation, ensure that there is a natural droop of 5-10mm in the middle of the chain.
