How does Bell air pump work?
Bell’s Air Attack Series floor pumps are specifically designed to inflate tires fast. Their high-volume, wide-barrel design pushes more air with each stroke to quickly inflate the wider tires found on most cruiser, mountain, BMX and kids’ bikes.
Why can’t I pump my bike tire?
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.
What PSI should my bike tires be at?
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.
How do I put air in my bike tire without a pump?
You’ll want to use anything at hand – preferably a towel, a piece of cloth, or a t-shirt to wipe it down. Once the valve is a little less unsanitary, you can proceed. Begin by blowing a small amount of air into the tire. You’ll want to use your tongue to put pressure on the valve to keep it open.
What are the two types of bike tire valves?
The two standard valve types are Schrader and Presta (photo). Schrader valves are identical to those found on car tires. These valves are generally used on hybrid and children’s bikes.
How many tires will a CO2 cartridge fill?
CO2 inflators depend on small metal canisters (also called cartridges) filled with compressed CO2. You want to be sure to get the right size cartridge for your tire size. Smaller ones will fill a single road tire. The larger ones can fill two tires.
Do bike CO2 cartridges expire?
Answer: There are no published expiration dates on CO2 Cartridges. CO2 cartridges stored properly and free from corrosion last forever.
Are Bell bike pumps good?
The Bell Air Attack 650 is a very high volume pump with a max volume of 630 cubic centimeters, meaning it moves about twice as much air per pump stroke as most other pumps we tested. This makes it ideal for low-pressure tires. It’s also extremely inexpensive, and this shows in the quality of the construction materials.
