sorry if there's a thread on this, I'm still fairly new here.

Does anyone ride a "fixie" on here? one of them thar bikes with only one speed and no brakes.

I see quite a few people here zipping around in them, and I think they are the scariest, craziest things to ride in a city (and a hilly one at that). I've had so many instances where I needed to stop very quickly, how in the world do those riders stop in time?!
