Bicycle Flywheel - Function and benefits Install the bicycle flywheel on the rear wheel. When the rider pedals, energy is transmitted via the chain to the flywheel. Due to the flywheel’s inertia, energy is stored and used to rotate the rear wheel, helping propel the bicycle forward. This mechanism contributes to a smoother ride by smoothing power delivery and maintaining momentum. - Why you need it The flywheel is an essential rear-wheel accessory that improves ride smoothness and stability. By storing energy and releasing it through the rear wheel, it reduces sudden changes in pedal force and helps the bike roll more evenly over varying terrain. - Material and quantity Material: high-strength steel Quantity: 1 piece - Durability and performance Designed for higher wear resistance, high strength, and improved durability. The flywheel offers longer service life and better endurance under regular riding conditions. - Installation note Install the bicycle flywheel on the rear wheel as part of standard setup for this component. - Use scenarios 1) Urban daily commuting: smoother cadence and steadier power delivery on potholes and pavement irregularities. 2) Long rides and hills: maintains momentum through climbs and descents, reducing fatigue from constant pedaling. 3) Rides on rough roads or gravel: enhanced stability and smoother feel when power delivery is intermittently disrupted by terrain.
