I think riding with brakes is illegal pretty much everywhere. Also, most of the fixed gear bikes I've seen do have brakes. Only the most purpose built track frames don't have brake mounts, for example I own an ex-keirin NJS frame without brake mounts, bottle mounts, etc. I tried using a clamp on brake with it so I could ride it on the road, but I didn't feel comfortable since I don't think the fork was really designed for those forces, so it's now a track-use bike only.
