A "Single-Speed" bicycle is a type of bike that has only one gear ratio. This means that the rider cannot change gears while riding, making it simpler to operate. Single-speed bikes are often lighter and require less maintenance than multi-gear bicycles, making them popular for urban commuting and casual riding. These bikes are typically designed for flat terrain, as they may not perform well on steep hills. Riders benefit from a straightforward riding experience, as they can focus on pedaling without worrying about shifting gears. Single-speed bikes are often associated with fixed-gear cycling and are favored by many for their minimalist design.
