Function and mechanism - Install the flywheel on the rear wheel. When the cyclist pedals, energy is transferred to the flywheel via the chain. The flywheel’s inertia stores this energy and helps rotate the rear wheel, contributing to forward motion. Why you need it and how it solves problems - Smoother ride: The inertia of the flywheel smooths power delivery, reducing torque peaks and delivering steadier acceleration and cadence. - Maintains momentum: Stored energy helps maintain motion between pedal strokes, which can reduce rider fatigue on variable terrain. - Important rear wheel accessory: Acts as a crucial component to improve ride quality and stability, especially during changes in terrain or speed. Material and durability - Construction: Steel and aluminium materials provide higher wear resistance, high strength, and durability. - Endurance: The combination of steel and aluminium enhances long-term endurance and reliability in regular use. Performance and fit - Connection and operation: High precision threads ensure a tight connection with the hub, enabling smooth operation, accurate engagement, reliability, and good overall performance. Use scenarios - Urban commuting: Helps smooth power delivery on mixed surfaces and frequent stops, resulting in a more comfortable ride. - Long-distance riding and training: Provides consistent cadence and steady feel over lengthy sessions. - Hills and varied terrain: Improves stability and momentum on climbs and descents, aiding riders who encounter changes in elevation during rides.
