It's time to take a big ride. Low tire pressure or flat tire? No worries.
This alloy mini bicycle pump can create up to 60 psi, enough air pressure for most bike tires. Fast and easy to pump; great for mountain bikes, road bikes, and comfort bikes when you carry it our on the road and suitable for daily pumping kids' bikes.
The rotating nozzle accommodates both Schrader and Presta valves and is held in place by a locking level.
Just exactly put the proper valve head on the bicycle's gas nozzle and then open the lever upwards to look on the nozzle. This tightens down the rubber nozzle to ensure no air loss.
