Hey, I’ve recently gotten into MTB and started learning the anatomy of a bike.
The rear hub makes a clicking noise when coasting but is silent when pedaling – this is caused by springs or ratchets in the hub either engaging with the rest of the system or going the opposite direction, causing the springs (ratchets) to click.
And here is what I cannot fully grasp: What makes the inside of the hub suddenly start going in the other direction when coasting?
Sorry if my description was somewhat vague but I did my best 😀
Thanks!

It isn’t that the inside of the hub has started going backwards. It’s that the rest of the drive train (pedals, gears, chain) has STOPPED moving with respect to the wheel. So, from the perspective of the hub, the drive train is effectively moving in the opposite direction. This is why you get the same clicking noise if the bicycle is stopped, but you run the pedals backwards.
