A fixed wheel bicycle has no freewheel. It does not allow the rider to coast. The pedals are always in motion when the bicycle is moving. On a fixed wheel, or one speed bicycle, the sprocket is screwed directly onto the hub. A sprocket, in this case, is a wheel with teeth that meshes with a chain.
There are a number of reasons riders prefer this type of bicycle. They believe that the pedaling method improves because the rider’s rhythm is less likely to be interrupted while the bicycle is in motion. This is due to the simple fact that if the rear wheel is moving so are the pedals. Coasting is not an option. Therefore the legs are not allowed to stiffen up and circulation improves.
Further advantages to this type of bicycle are that it is lighter in weight for the simple reason that it does not need the hardware that a comparable multiple speed cycle does and as a result is easier to fix if something breaks. Also there is less chain to deal with as it is shorter due to the fact that it is a straight line from the pedal crank to the wheel hub.
One disadvantage to riding a single speed bicycle is that going down a hill can be more difficult for the simple reason that riders are forced to pedal faster. Unfortunately for some, coasting, while always an option on a bike equipped with a freewheel, is still not an option but braking can be if done correctly. If coasting is tried a rider will most certainly get a kick, by a pedal, in the trailing leg or fall after losing control.
Another disadvantage, especially for a beginner, is trying to turn a corner at higher speeds. The pedals tend to hit the road which would likely cause a loss of control. The rear wheel could lift off the ground causing a fall. The way to avoid this is to ensure your pedals don’t stick out to far and have adequate ground clearance.
To riders of a fixed wheel bicycles the advantages of riding it surpass the disadvantages by a wide margin. Especially when former riders of multiple speed bicycles become comfortable with the change in style and the fewer options available to them for getting down a hill. After all coasting is not allowed. What appeals to them is the simpler ride and the closer connection to road and bike.
