How Does a Fixed Gear Bike Work?
Single Gear Bicycle Mechanics
-
A fixed gear bike uses a standard bicycle chain attached to a single gear which allows the bike to be powered(pedaled). In contrast to a multi-speed gear bicycle, such as a ten speed, a single gear bike has only one gear, also commonly called a sprocket or a cog. There are no gear shift levers needed to switch between multiple gears, and there is no derailleur system.
Pedaling Mechanics and Bicycle Power
-
As a fixed gear bicycle is pedaled by its rider the bicycle chain, which is anchored to the single gear by a series of teeth, pulls on the rear cog, or gear. The rear cog is attached to the rear wheel, and causes movement. Force applied to the bicycle pedal is transferred through the pedal arm, through the bicycle chain, and ultimately to the rear gear. This chain of events make up the basic operating principles of a fixed gear bicycle.
Bicycle Guidance and Braking
-
As a fixed gear bicycle is pedaled, its rider determines its direction by turning the bicycle handlebars in the desired direction. Most single gear bicycles have brake levers that are mounted on the front handlebars, which are simply grasped by the rider's hands and squeezed, which activates the braking mechanism and stops or slows the bicycle.
