I'm not exactly sure that is true. If they have a brake mount and at least one brake, they are street legal. Do you have a source for your assertion?

Indeed, mounting at least one brake seems to satisfy that particular judge. http://www.sacramentopress.com/headline/10251/Riding_Cool_fixedgear_bikes_without_brakes http://www.sacramentopress.com/headline/10251/Riding_Cool_fi... So, yes, again, you can mount 'a brake' and be legal in some places but not everywhere, the whole thrill here seems to come from not having all that 'stuff' on the bike. If you've ever done any serious bicycling then you realise that the fixed wheel bike has no other place than the track. In traffic you'd have to be an artist to safely ride one and the problem with them being in traffic is not just that you'd have to be an artist but also that circumstances can determine what is safe and what is not. Brakes are used for normal reduction in speed, in such cases a fixed gear will do, after all, all you're doing is removing energy from the 'system' (bike + rider) in the same way you put it in, through your leg muscles. But brakes have a second function as well, which is to react to traffic conditions, things outside of your control. And you may find that you need to remove energy from the 'system' a lot quicker than you originally put it in. For a bike with a fixed gear (one without a freewheel) this will mandate you to continue to make pedalling motions while you are using that other brake. If the reason why you need to brake stops you from doing that you are now in deep trouble because you will find two nice sized hammers roughly where your pedals used to be that are pounding the crap out of your legs, which can easily cause you to completely lose control of your bike. If you happen to be unbalanced a pedal can strike the road with incredible force and if your foot happens to be between the pedal and the road that's really bad. So, where-ever the legislation hasn't caught up yet with fixed gear bikes being outlawed because of the 'trend' will sooner or later do so because they're simply not as safe as bikes that have freewheels. It's a pity for the few people that started this trend and that know their stuff and are only endangering themselves, but now that the masses are flooding in and are copying the couriers legislation seems to be the answer taken by the authorities. In the Netherlands, bicycle country #2 after China I believe they've been illegal since 1950 or so.

  I've ridden a fixed gear bike exclusively for the past 15 years. (alright, that's not exactly true... I have a dutch bike for groceries and recently bought a Brompton for traveling) It was built for me by the patron saint of internet cyclists, Sheldon Brown (RIP). http://www.sheldonbrown.com/fixed.html http://www.sheldonbrown.com/fixed.html You just need a front brake to dump speed, and ride a gearing suitable for your environment. For instance, in NYC this is about 42/16.

    Going fast and having just a front brake can easily cause you to do a forward flip. 80% of your stopping power is in the front brake, but if you're going very fast engaging the front brake for an emergency stop can make a bad situation worse. That's a pretty sad story there, I read a bit on his site and he seems to have been a very nice and knowledgeable guy. I'm pretty sure he would have smiled at the way you characterised him, there are worse things that people could say about you after you die. For an analogue, you can drive in traffic with a car and never touch the brakes, if you're a really good driver and you plan ahead. So, in theory you could remove your brakes and still be safe. So, now for the obligatory 'think of the children' argument, but it could just as easy be the think of other people in traffic that do unexpected stuff or the mistakes that you yourself might make (nobody is infallible): Until the day that that toddler walks out in front of you. And then, whether you're in a car or on a bike doing a good clip you're going to be very happy that you have all the stopping power that you could possibly want. Now a clever counter argument would be that a freewheel cycle with discs on front and rear wheels would offer less stopping power than a fixed gear cycle similarly equipped. As for bike styles, I have a recumbent (a Zephyr) for fast touring on bike trails but I'd never ever take it in to traffic with vehicles around me (too low), also it has a very large bell on it (and I don't care if people think it's gay), because people are simply not used to bikes doing that sort of speed.

      I've never bought the front brake argument. As a bicyclist, motorcyclist, and physicist, I know that 100% of your stopping power is on the front brake, exactly because (as you say) the front brake can make you do a forward flip. This means that all your weight is on the front wheel, and the only thing you can do with your rear brake is make the rear wheel lose traction, and that will indeed make a bad situation worse. The answer is to become proficient in the use of your front brake and commit the proper brake pressure to muscle memory so that you do not grab at it and skip the front wheel before weight has shifted, or do a "stoppie". Practice maximum braking from speed, it could save your life! There is one counter-argument to this: In situations with poor traction (on snow, ice, sand, etc.) you don't have enough traction to shift all your weight to the front. In those cases, the optimal case is judicious use of both brakes. But if you bike on such surfaces, you have much more to learn anyway... Second lesson: People rely too much on brakes. In most high-speed situations, swerving is a better action. (Due to the way braking distance vs turning distance scales with speed.) Practice change direction quickly to avoid obstacles in your path! Sorry for the long post, but it was fresh in my mind: My wife got side swiped by a car turning right yesterday. She's fine, but we had a long discussion about bicycle proficiency and the futility of being "dead right".
