- Function and mechanism: Install a bicycle flywheel on the rear wheel. When the cyclist pedals, energy is transferred to the flywheel via the chain. The flywheel's inertia stores the energy and helps drive the rear wheel, contributing to forward motion. - Ride quality and advantages: The bicycle flywheel is a key rear wheel accessory that smooths the ride by providing stable energy delivery and reducing pedal force fluctuations. - Material and durability: Made from alloy with high wear resistance, high strength, and durability for long term use. - Compatibility and performance: 11 speed freewheel compatible; supports bicycle flywheel and provides smooth, reliable shifting performance with 11 speed drivetrains. - Use scenarios: - Daily commuting on routes with varying terrain where smooth power delivery improves comfort and efficiency. - Hill climbs and sustained riding, where flywheel inertia helps maintain momentum during climbs and accelerations. - Road cycling or endurance training requiring consistent shifting and durable drivetrain components. - Key attributes at a glance: function aided by chain transfer to a high inertia flywheel; compatibility with 11 speed freewheel systems; alloy construction for wear resistance and strength; designed to deliver smooth shifting performance and durable operation.
