Kiinnityskoneistot

Kiinnityskoneistot, also known as fixed-gear bicycles, are bicycles that have a single gear ratio, typically a high gear, which is fixed and cannot be changed. This design is achieved by using a chain that is secured to the pedals and the rear wheel, with no derailleur or freewheel mechanism. The simplicity of this design results in a lightweight and durable bicycle that is easy to maintain and repair.

The fixed-gear design has been popularized by cyclists who use it for its simplicity and the challenge it presents in terms of pedaling and braking. The lack of gears means that the cyclist must adjust their pedaling speed to match the terrain, which can be a rewarding experience for those who enjoy the physical challenge. Additionally, fixed-gear bicycles are often used for urban cycling, as they can be ridden on flat surfaces and do not require frequent gear changes.

The fixed-gear design has been used in various forms throughout history, with early examples dating back to the 19th century. However, it gained popularity in the 1970s and 1980s as a means of challenging oneself and pushing the limits of human endurance. Today, fixed-gear bicycles are still used by cyclists of all levels, from beginners to experienced riders.
