Function and mechanism - A bicycle flywheel installed on the rear wheel stores energy through inertia. When you pedal, energy is transferred to the flywheel via the chain, and this stored energy helps rotate the rear wheel to drive the bike forward. Key benefits - Smoother ride: The energy stored in the flywheel smooths power delivery, reducing pedal fluctuations and providing steadier propulsion. - Improved efficiency: Inertia helps maintain momentum, supporting consistent speed with less effort on each pedal stroke. - Reliable performance: The flywheel works with consistent, predictable operation to enhance riding comfort on varied terrain. Material and durability - Made from alloy with high wear resistance, high strength and durability, delivering improved endurance over time. Fit and reliability - High precision threads ensure a tight, secure connection with the hub, enabling smooth operation, accuracy and reliable performance. Installation and operation - Install the flywheel on the rear wheel; during pedaling, energy is transferred to the flywheel via the chain, and the inertia of the flywheel drives the rear wheel. Use scenarios - Daily urban commuting: On city roads, the flywheel provides smoother power delivery and a more comfortable ride. - Long-distance rides on mixed terrain: Maintains momentum over rollers and changes in grade, reducing pedal strain. - Bike upgrades and reliability improvements: Enhances ride quality and rear-wheel smoothness for riders seeking consistent performance.
