BICYCLES


What is a FIXIE bike?

A fixie bike, also known as fixed gear, fixed wheel, etc ... is a bicycle whose rear sprocket is fixed the hub rotates the wheel both forward and backward.

It is a type of bike that offers greater control for those riding. You may, for example, pedaling backwards. Unlike the impeller, as is the case of the conventional bicycle, or the bicycle will move up according to the pedaling cycle is faster walk faster and vice versa. The speed and braking are controlled exclusively by the legs.

What is the difference between a bicycle and FIXIE Single Speed?

A Fixie uses fixed pinion a Single Speed free pinion, both have only one speed.

Currently the Fixies use Flip-Flop hubs on the rear wheel, so you can install a pinion or a freewheel side of the cube. Thus the bicycle can also function as a Single Speed, there is no need always be pedaling to turn on the bike, even allowing a greater comfort for the rider.

short, one Fixie generally can also function as Single Speed a Single Speed typically uses a normal cube with pinion / freewheel, so you can not function as Fixie.
