However much I'd like to think that fixed gear bikes are so simplistic and barebones, in fact coaster-brake bikes are equally simplistic if not more because there are NEVER rim brakes on them while a lot of people ride fixed with brakes. Point being that our niche of simple, grassroots riding is conspiculously challenged by the popularity of lesiure coaster-brake bikes which look just as simplistic on the outside. Now I realize that a coaster brake hub has some internals that a normal flip-flop does not but it's a minimal difference from the outside. That's an observation, now a question: how in the world does a coaster brake work? Can anyone explain the internals?
Disclaimer: I got a lot of "big" words floating around in my head that I may not have used here correctly.
