Fixies, or fixed-gear bicycles, are characterized by their simplicity and minimalist design. These single-speed bikes have a fixed drivetrain, meaning the pedals are always in motion when the bike is moving. Fixies are popular among urban riders and bike messengers for their straightforward mechanics and low-maintenance requirements.

Fixie bikes offer a pure and connected cycling experience, as the fixed-gear setup requires constant engagement and encourages a smooth pedal stroke. The lack of complex components makes fixies lightweight and easy to maintain, while the clean aesthetics appeal to riders who appreciate a sleek, modern design.
