Fixed-gear bicycle
From Wikipedia, the free
encyclopedia
A fixed-gear
bicycle (or fixed-wheel bicycle, sometimes known as
a fixie) is a bicycle that has no freewheel, meaning it cannot coast, because the pedals are
always moving when the bicycle is in motion.In Australia,
"fixed-wheel" is the normal term for the subject of this
article—meaning the opposite of freewheel,
and "fixed-gear" usually refers to a single-speed bicycle.
The sprocket,
or cog, is threaded or bolted directly to a fixed rear hub. When the rear wheel
turns, the pedals turn in the same direction.[1] This
allows a cyclist to stop without using a brake, by resisting the rotation of the cranks,
and also to ride in reverse.
As a rule, fixed-gear bicycles are
also single-speed bicycles—bicycles without derailleurs,
with a single sprocket attached to the rear hub, and a single sprocket attached
to the crank. Most fixed-gear bicycles only have a front brake, and some have
no brakes at all.
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.[3]
In urban North America fixed-gear bicycles have achieved tremendous
popularity, with the rise of discernible regional aesthetic preferences for
finish and design details.[17]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.[4] In
the UK until the 1950s it was common for riders to use fixed-gear bicycles for
time trials. The
fixed-gear was also commonly used, and continues to be used in the end of
season hill climb races in the autumn.
Dedicated fixed-gear road bicycles are
being produced in greater numbers by established bicycle manufacturers. They
are generally low in price[18] and
characterized by relaxed road geometry, as opposed
to the steep geometry of track bicycles.[19]
Fixed-gear bicycles are also used
in cycle ball, bike polo and artistic cycling.
