A floor pump is a device used to inflate tires on bicycles and other inflatable items. It consists of a long tube connected to a sturdy base, allowing users to pump air into tires efficiently. The pump typically features a gauge to measure the pressure, ensuring that tires are inflated to the correct level for optimal performance. Most floor pumps come with a dual head that fits both Schrader and Presta valves, making them versatile for different types of bicycles. They are designed for ease of use, requiring less effort than hand pumps, and are ideal for home or garage use.
