Fixed-gear bicycle

A fixed-gear bicycle (or fixed-wheel bicycle, commonly known as a fixie) is bicycle that has a  with no freewheel mechanism. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantages of simplicity compared with the standard multi-geared bicycle.drivetrain

Most bicycles 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 rider cannot stop pedalling. When the rear wheel turns, the pedals turn in the same direction. This allows a cyclist to apply a braking force with the legs and bodyweight, by resisting the rotation of the cranks. It also makes it possible to ride backwards although learning to do so is much more difficult than riding forward. 

As a general rule, fixed-gear bicycles are single-speed. A derailleur cannot be fitted because the chain cannot have any slack, but hub gearing can, for example a Sturmey-Archer fixed-gear 3-speed hub, in which case is a fixed-gear multi-speed arrangement. Most fixed-gear bicycles only have a front brake, and some have no brakes at all.

Uses[edit]

The track bicycle is a form of fixed-gear bicycle used for track cycling in a velodrome. But since a fixed-gear bicycle is just a bicycle without a freewheel, a fixed-gear bicycle can be almost any type of bicycle.

Some road racing and club cyclists used a fixed-gear bicycle for training during the winter months, generally using a relatively low gear ratio, believed to help develop a good pedalling style. In the UK until the 1950s it was common for riders to use fixed-gear bicycles for time trials. The 1959 British 25 mile time trial championship was won by Alf Engers with a competition record of 55 minutes 11 seconds, riding an 84 inch fixed-gear bicycle. The fixed-gear was also commonly used, and continues to be used in the end of season hill climb races in the autumn.  A typical club men's fixed-gear machine would have been a "road/path" or "road/track" cycle. In the era when most riders only had one cycle, the same bike when stripped down and fitted with racing wheels was used for road time trials and track racing, and when fitted with mudguards (fenders) and a bag, it was used for club runs, touring and winter training.By the 1960s, multi-gear derailleurs had become the norm and riding fixed-gear on the road declined over the next few decades. Recent years have seen renewed interest and increased popularity of fixed-gear cycling.In urban North America and similar areas in other English-speaking cities, fixed-gear bicycles have achieved significant popularity, with the rise of discernible regional aesthetic preferences for finish and design details.Dedicated fixed-gear road bicycles are being produced in greater numbers by established bicycle manufacturers. They are generally low in price and characterized by relaxedroad geometry, as opposed to the steep geometry of track bicycles.Fixed-gear bicycles are also used in cycle ball, bike polo and artistic cycling. Bike messengers frequently use fixies due to their durability, low maintenance, simplicity and ease.A fixed-gear bicycle is particularly well suited for track stands, a manoeuvre in which the bicycle can be held stationary, balanced upright with the rider's feet on the pedals

THE BIKE THAT IS GOOD DESIGN AND GOOD CREATION (OPTIONAL)

1. The Kilo Glow series (by pure fix)

This bicycle is the same if we see in the daylight but when its midnight you can see that the bicycle frame are glowing. Its because the frame of the bicycle are paint with glow in the dark paint. This bicycle is good when you cycle at midnight.    

2. Vilano WAVE Freestyle

This bicycle name curved is because is curvy seat tube and vibrant '80s color schemes. The model of this bike is a title bit rear because its have a triangel shape above the seat.  

3. Pure Fix "The India"

This bicycle good in the paint because the colour is gold mix with gray. The bicycle is more high class because is rear to have this bicycle.
