A single-speed flywheel is a bicycle transmission component that allows the rider to coast without pedalling while still providing the ability to pedal forwards. It is commonly found on single-speed bicycles and some other types of bicycles that are not shifted, and has become popular in recent years on new national standard bike sharing and electric bicycles. A single-speed flywheel consists of a set of sprockets (also known as a gear train) attached to the hub of the rear wheel. Inside the flywheel mechanism, there are ratchet teeth that engage when you pedal forward, allowing you to drive the bike forward. When you stop pedalling, the ratchet mechanism releases and you are free to glide. Common tooth sizes are 12T,14T,16T,18T,20T,22T,24T.
