Bicycle pumps are essential tools used to inflate bike tires, ensuring they have the correct air pressure for a smooth and safe ride. They come in various types, including floor pumps, hand pumps, and CO2 inflators. Floor pumps are ideal for home use, providing high-volume air quickly, while hand pumps are portable and convenient for on-the-go inflation. CO2 inflators use cartridges for rapid inflation, often used by cyclists in emergencies. Maintaining proper tire pressure with a bicycle pump helps improve performance, reduce the risk of flats, and enhance overall riding comfort.
