Key benefits - Energy transfer and storage: When you pedal, energy is transferred to the flywheel via the chain. The flywheel's inertia stores this energy, which then helps rotate the rear wheel to drive the bike forward. - Smoother ride: The flywheel acts as a new important rear wheel accessory, smoothing the ride by stabilizing pedal input. - Reduced effort on long rides: The flywheel reduces weight and strain on long journeys, supporting faster riding with less perceived effort and quieter operation. - Easy shifting control: The unique design of the mountain bike sprocket enables easy control of shifting functions, improving handling and confidence on varied terrain. Material and durability - Material: Steel with higher wear resistance, high strength, and durability to withstand regular riding and tougher conditions. Performance and design - Function and performance: The system uses chain-driven energy transfer to store and release energy via the flywheel, helping the bike move forward smoothly. - Quiet operation: Designed to operate with minimal noise during use. Size and compatibility - Size and compatibility details are dependent on your bicycle model. Please verify fitment with your rear wheel configuration and sprocket system before installation. Use scenarios - Mountain biking on mixed terrain: The unique sprocket design supports easy shifting control while the flywheel provides smooth power delivery over rough sections. - Long-distance road riding or touring: Energy storage helps maintain speed with less rider fatigue, while reducing ride strain and noise on extended trips. - Daily commuting and recreational riding: Enhanced ride smoothness and quieter operation improve comfort and enjoyment during regular rides.
