well with no brakes how will u stop?
Straight from Wikipedia:
Because there is no freewheel mechanism, fixed gear bicycles cannot coast. Whenever the rear wheel is turning, the pedals turn in the same direction. By resisting the forward motion of the pedals, a rider is able to slow the bike to a stop, without the aid of a brake. They can also be ridden in reverse, although the forward-oriented geometry of any bicycle makes this more of a stunt than a practical technique.
A rider can also lock the rear wheel and skid to slow down or completely stop on a fixed-gear bicycle, a maneuver sometimes known as a skid stop. It is initiated by unweighting the rear wheel while in motion (and usually lifting it off the ground slightly) by shifting the rider's weight forward and pulling up on the pedals using clipless pedals or toe clips. The rider then stops turning the pedals, thus stopping the drivetrain and rear wheel, while applying his or her body weight in opposition to the normal rotation of the pedals. When the rear tire again contacts the ground the rear wheel will skid, which acts to slow the bike. The skid can be held until the bicycle stops or until the rider desires to continue pedalling again at a slower speed. The technique requires a little practice and using it while cornering is generally considered dangerous. As with the technique of resisting the pedals, the maximal deceleration of this method of slowing is also significantly lower than using a front brake. A wet surface further reduces the effectiveness of this method, almost to the point of not reducing speed at all.
