Single speed bicycles are designed with only one gear ratio, meaning they have a single gear for both pedaling and coasting. This simplicity makes them lightweight and easy to maintain, as there are fewer components compared to multi-gear bikes. They are ideal for flat terrains and urban commuting, where frequent gear changes are unnecessary. Riders of single speed bicycles benefit from a straightforward riding experience, as they do not have to worry about shifting gears. These bikes often feature a minimalist design, appealing to those who prefer a clean aesthetic. Popular among city cyclists, they are also known for their durability and efficiency.
