Fixed-Gear



  A fixed-gear bicycle (or fixed-wheel bicycle, fixie) is a bicycle that has no freewheel, meaning it cannot coast, as the pedals are always in motion when the bicycle is moving. 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. This allows a cyclist to stop without using a brake, by resisting the rotation of the cranks, and also to ride in reverse.
  In urban North America fixed-gear bicycles have achieved tremendous 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.
  One of the main attractions of a fixed gear bicycle is low weight. Without the added parts required for a fully geared drive train, a fixed gear bicycle will weigh significantly less than its geared equivalent. Also, a fixed gear drivetrain is more mechanically efficient than any other bicycle drivetrain, with the most direct power transfer from rider to the wheels. Thus, a fixed gear will require less energy in any given gear to move than a geared bike in the same gear. Hit read more to see a few more styles of fixed-gear bikes.
