I'm trying to understand how I can "coast" on my bycicle. The net isn't being much help because apparently "coasting" is also a kind of shifter/brake develope by Shimano and it's poluting my search results.
On a car I need to take it out of gear or keep the clutchpedal down to coast but on a bike all I have to do is to stop pedaling and the rear wheel keeps spinning conserving the momentum. What's the mechanism behind this? Are there one-way bearings involved or is there something simpler?
