Bicycle floor pumps offer the most leverage and air volume to inflate your bicycle tires making them the fastest and easiest solution. A good floor pump will last many years and may even be rebuildable when it finally does go. Most floor pumps have a gauge but if you are interested in the most accurate pressure choose one with a digital gauge. If you have tubeless tires you will need a pump with a "burst tank" that pushes out a large volume blast of air sealing the tubeless tire to the rim. A metal barrel, steel braided hose, and high quality components are things to consider in a floor pump that will get consistent use. You may also want a "smart head" that allows you to fill both presta and schrader valves, or a head that allows you to switch from valve type. This is especially important if you have both kids bikes and adult bikes in your garage.
