I got a dans comp catalog today, and was looking through at the new things, and I saw this Fit Flow Street.. and upon closer inspection, saw the bit about it coming with caliper brakes, and how they don't recommend riding brakeless. Thought it was pretty interesting, hadn't seen a bike in there without at least a rear brake before. Pretty cool though. I dunno if Fit was the first one to make a complete bike that doesn't officially come with brakes or not..
It officially comes with brakes, which why they have the calipers. In fact, it's why the frame (and Edwin's earlier signature frame) even has a hole to put calipers on in the first place; the reason being that you can't sell a frame that can't use brakes or sell a complete without brakes.
