What it is - A bicycle flywheel installed on the rear wheel to store energy and smooth power delivery during pedaling. How it works - When you pedal, energy is transferred via the chain to the flywheel. - The flywheel’s inertia stores this energy, rotates the rear wheel, and helps propel the bike forward. Key benefits - Improves ride smoothness by reducing drivetrain shocks and providing steadier power transfer. - Supports a more comfortable cadence, especially under variable riding conditions. - Durable steel construction offers lasting wear resistance and strength in use. Material and construction - Made of steel with high wear resistance, high strength, and durability. Compatibility and performance - Fits 10-speed systems with a 10-speed freewheel. - Designed to work with and support smooth-shifting systems. Installation and use - Step 1: Install the bicycle flywheel on the rear wheel as part of the drivetrain. - Step 2: Pedal to transfer energy from the chain to the flywheel. - Step 3: The flywheel’s inertia stores energy and helps rotate the rear wheel, contributing to forward motion. Use scenarios - City commuting and daily riding: benefits from smoother starts, steady power delivery, and reduced drivetrain stress during frequent stops. - Long rides and hilly terrain: energy storage helps maintain momentum and reduces pedal effort on climbs. - Replacement or upgrade: suitable for riders with a 10-speed drive train seeking improved durability and consistent performance. Notes - The description reflects the product’s function, compatibility, material, and performance as described, without adding or omitting features.
