The fixed gear bicycle continues to gain popularity among the bicycle community. First popularized by bike messengers, the fixed gear bike, fixed wheel bicycle, or fixie bicycle, through the years has developed a cult following in many parts of the world. There are many reasons as to why fixed wheel bikes have become a hit among cycling enthusiasts. But many people are captivated with the simplicity of these bikes, not to mention that fixie bikes are very much lightweight. Fixed gear bikes also generally come in cheaper prices as compared to other types of bikes and are easier to maintain with less parts than their bicycle counterparts.
The anatomy of a fixed wheel bike consistors of the sprocket being directly attached to its hub making freewheeling impossible. This makes the pedals move continuously each time the bike is in motion, following the direction of the rear wheel. A fixed gear bike can safely run with or without brakes since stopping the motion of the pedal will automatically stop the bike, although there are some areas that makes illegal bikes not equipped with breaks.
A fixie bicycle usually runs on single speed, meaning, this type of bike sports a single gear. But it is possible for fixie bikes to have multiple gears and allow changes in speed while in motion. A number of fixies have already been manufactured with this feature but rarely do we see one since multiple gears may not be fit with the simplicity concept that fixie bikes are famous for.
