How they work. The bicycle pump compresses air. When the cylinder is compressed, air is pushed down the tube of the pump and then into the tire via the valve, which is forced open by the pressure of the air. Some pumps have a gauge that shows the pressure of air that is forced into the tire.
What type of bike pump do I Need?
- In a nutshell, you need a bike pump that’s compatible with the valves on your bike tires and capable of providing enough pressure. There are two common valve styles: Presta and Schrader, so get a pump that’s compatible with your valve type.

Why is my bike pump not working?
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 does air tire pump work?
When the pump is pulled up, the pressure inside decreases. This pulls in air from the outside but closes the valve to the bike tire. When the piston is pushed down again, it compresses the air inside. This closes the inlet valve and opens the valve to the tire, pushing air into the bike.
Do bike pumps work on balls?
Purchase a decent air pump for balls if you have not done so already. Pumps aren’t too expensive and are easy to find. You can even use a bike pump with the proper needle. You’ll need to purchase a ball needle if your pump doesn’t already have one.
Can a bicycle pump be repaired?
Manually operated bicycle pumps are essentially piston and cylinder machines that compress air and force it into the inner tube. Repair a leaking pump head by unscrewing the nut and replacing the seal. If the head is leaking at the connection to the hose, replace the connector with an adjustable hose clamp.
Is bicycle pump adiabatic?
What it shows: An adiabatic process is one where no heat enters or leaves a system. Here we compress a gas adiabatically inside a bicycle pump. The work done on the gas increases its internal energy, so increasing its temperature in accordance with the first law of thermodynamics.
Is a bicycle pump a single acting or double acting compressor?
The bicycle pump is a simple example. Piston pumps can also be double acting with inlet and outlet valves on both sides of the piston. While the piston is in suction on one side, it is in compression on the other.
How does the bike pump function as a vacuum pump?
Unlike most piston pumps, a bike pump uses the rubbery disk both as a piston and as one of the check valves. When you pull back on the pump, the disk flexes inward and allows air around it, into the cylinder ahead of the piston.
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.
Can you inflate an exercise ball with a bike pump?
You can use just about any pump to re-inflate a yoga ball. A bicycle pump, a home air compressor or a gas-station air compressor all work, although in most cases you need a cone-shaped adapter to get the air into the ball efficiently.
What is a Moisten needle?
The purpose of moistening the needle is to prevent the needle from damaging or pushing the valve into the bladder. Saliva is more viscous than water; which is better for being a lubricant.
