A "single-speed" bicycle is a type of bike that has only one gear ratio. This means that the pedals turn at the same rate regardless of the bike's speed. Single-speed bikes are simple in design, making them lightweight and easy to maintain. They are ideal for flat terrains and urban commuting, where frequent gear changes are not necessary. Riders of single-speed bikes benefit from a straightforward riding experience. Without the complexity of multiple gears, cyclists can focus on enjoying their ride. This type of bike is popular among city dwellers and those who prefer a minimalist approach to cycling, often associated with the fixed-gear or track cycling communities.
