- To blow air into the bike, put both feet on the pump’s base and use both arms to pull up the level and then push down. The air pressure gauge on the pump will indicate when you’re close to reaching the appropriate tire pressure.
What does the lever on a bike pump do?
You press the chuck onto the valve, then pull the lever up to lock the chuck to the valve. Otherwise pressure could blow the chuck off on higher pressure tires. It’s to make the head fit the valve snugly.
What does S and P mean on a bike pump?
Valve types There are two basic types of valves that you’ll find on bikes: Presta and Schrader. Schrader valves are too thick to fit through the tube hole in a road rim, and Presta valves will need adapters or shims (or an awful lot of electrical tape) to fit on an MTB rim.
Why does my bike pump not work?
Make sure you press hard enough to fully seat the pump fitting onto the valve. If that doesn’t help, your tire valve could be stuck closed, or the pump fitting (the thing you press over the tire valve) might be broken. Inside the pump that attaches to the stem is a micro bolt with a vertical line.
How do you pump up a bike tire without losing air?

How much air do you put in bike tires?
Tire inflation basics The tires don’t sag down and create a large surface area, because it’s simply not needed. A typical road tire should be inflated to something between 90 and 120 PSI. Mountain bike tires, on the other hand, tend to run at much lower PSI.
Can I use a car tire pump on my bike?
The long answer: The reason you can sometimes use an automotive air-pump on a bicycle tire/tube is because they share an identical valve. (See: Schrader valve/Schrader tube in the Terminology Index). If you have this type, you will definitely be able to get air into your tubes in a pinch.
