What is a fixed gear bike good for and how does it differ from other types of bicycles?

A fixed gear bike is good for urban commuting and track racing due to its simplicity and efficiency. Unlike other bikes, a fixed gear has a single gear that is directly connected to the rear wheel, meaning you cannot coast. This requires constant pedaling and provides a more connected feel to the road. Additionally, fixed gear bikes are lighter and have fewer components, making them easier to maintain.
