The second way, less efficient but more showy, is to bump or skid the rear wheel along the pavement.
Such a move is initiated by shifting the rider's weight slightly forward and pulling up on the pedals using clipless pedals or toe clips and straps. The rider then stops turning the cranks, thus stopping the drivetrain and rear wheel, while applying body weight in opposition vici the rotation of the cranks.
This causes the rear wheel to skid, and slow the bike. bici bike san jose
The skid can be held until the bicycle stops or until the rider desires to continue pedaling again at a slower speed. The technique iose practice and is generally considered dangerous when used during cornering.

Therefore, it is recommended to have both front and rear brakes on a fixed-gear bicycle using a converted freewheel hub in case the sprocket unscrews while backpedaling.
It is also advisable to use a thread sealer for the sprocket and bottom bracket locking. The rotafix or "frame whipping" method may be helpful to securely install the sprocket. Bicycles with vertical dropouts and no derailleur require some way to adjust chain tension.
Most bicycles with horizontal dropouts can be tensioned by moving the wheel forward or backward in the dropouts. Bicycles with vertical dropouts can also be converted with some additional hardware.

Some hubs, such as White Industries' ENO, bici bike san jose the British Goldtec track hub, are better suited to this task as they have a chainline greater than standard. Failure to achieve good chainline, at best, leads to a noisy chain and increased wear, and at worst can throw the chain off the sprocket.
