- Function and operation: The bicycle flywheel is installed on the rear wheel. When the rider pedals, energy is transferred via the chain to the flywheel. Due to the inertia of the flywheel, the energy is stored, which drives the rear wheel and moves the bicycle forward. - Smooth ride: The bicycle flywheel is a key accessory on the rear wheel that helps make the ride smoother. - Material and durability: Made from aluminum alloy and stainless steel, providing higher wear resistance, high strength, and long-lasting durability. - Compatibility and performance: Available as an 8, 9, 10, 11, or 12-speed freewheel, supporting well-running shifting systems. - Use scenarios: - Daily urban riding and commuting with steady acceleration and reliable shifting. - Uphill or variable terrain where consistent energy delivery improves ride feel. - Long-distance or endurance riding where smooth pedaling reduces fatigue and enhances stability.
