The Mini-Foot-Pump Advantage - More or Less Our Mini-Foot-Pump weighs a mere 9 ounces and stands 5-1/2 inches off the ground. To inflate a bicycle tire, it takes 90 effortless strokes to 40 psi with your leg, conversely it takes more than 200 grueling arm compressions with the average hand pump. There is no more guessing - more or less air - with the built in 140 psi pressure gauge. You can inflate more soccer balls for the team with your foot without even breaking a needle or a sweat. And leave it to the Germans to understand the true meaning of "Mini" when they engineered the world’s smallest foot pump.
