How does a...???

Question

freecoaster hub for a bmx bike work compared to a cassete? a cassete is loud and making a clicking noise when its made i understand why but i can't explain it and if forces your cranks backwards when you go backwards but freecoasters are quiet when you ride and it doesn't force your cranks backwards.....how does that work?

Answer 1

On a freewheel hub the freewheel mechanism is in the cog. On a cassette hub the mechanism is in the hub. A cassette hub is lighter and should be more durable. Function wise, they should be identical.
