 Fixed Gear

       Fixed Gear "Fixie" ,Fixed Gear.No Brakes.Can't stop. Don't want to.
Fixed Gear is a bicycle that has a Drivetrain with no Freewheel mechanism.The freewheel was developed by early in the history of bicycle design but the fixed-gear bicycle remained the track racing design .more recently the "fixie" has become a popular alternative among the urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.Most bicycle hubs incorporate a freewheel to allow the pedals to remain stationary while the bicycle is in motion ,so that the rider can coast, i.e.,ride without pedalling using forward momentum.A fixed-gear drivetrain has the drive sprocket (or cog) threaded or bolted directly to the hub of the back wheel, so that the pedals are directly coupled to the wheel. During acceleration. the pedals crank drives the wheel, but in other situations,the rear wheel san drive the pedal cranks.
