Exercise Bike Flywheel Size Comparison – Performance and Feel
Does flywheel weight matter on an exercise bike? Yes. Compare the heavy flywheels on commercial bikes to lighter home models and learn how it impacts smoothness.
The Physics of a Heavy Flywheel
Explaining how a heavier flywheel creates more inertia, which results in a smoother, more continuous pedaling motion that feels more like a real road bike.
Commercial Flywheels: The Gold Standard
Commercial spin bikes often have flywheels weighing 20kg or more to provide a premium feel and withstand intense use.
Home Bike Flywheels: A Compromise
Home exercise bikes typically have lighter flywheels (5-15kg) to save on cost and weight, which can result in a slightly choppier pedal stroke.
Does Heavier Always Mean Better?
While generally true for smoothness, the quality of the bearings and drive system also play a crucial role in the overall feel of the bike.
