Direct quote from Sheldon
'Most fixed-gear riders only use a front brake--a rear brake is quite unnecessary on a fixed-gear machine.'
and then
'There is really no need for a rear brake on a fixed-gear bicycle. By applying back-pressure on the pedals, you can supply all the braking that the rear wheel really needs. In fact, it is fairly easy to lock up the rear wheel and make it skid, unless you are running a rather high gear.'
