It is possible to slow down or stop a fixed gear bike by resisting the turning cranks, and a rider can also lock the rear wheel and skid to slow down or stop on a fixed-gear bicycle. Such a move is initiated by unweighted the rear wheel while in motion by shifting the rider’s weight slightly forward and pulling up on the pedals using clip less pedals or toe clips and straps. The rider then stops turning the cranks, thus stopping the drive train and rear wheel, while applying body weight in opposition to the rotation of the cranks. This causes the rear wheel to skid, and slow the bike. The skid can be held until the bicycle stops or until the rider desires to continue pedaling again at a slower speed. The technique requires a little practice and using it while cornering is generally considered dangerous.
On any bike with only rear wheel braking, the maximum deceleration is significantly lower than on a bike equipped with a front brake. As a vehicle brakes, weight is transferred towards the front wheel and away from the rear wheel, decreasing the amount of grip the rear wheel has. Transferring the rider’s weight back increases rear wheel braking efficiency, but a front wheel fitted with an ordinary brake might provide 70% or more of the braking power when braking hard.
