Before using a pump, check your tire valve. Bicycles generally use one of two types:
Presta valves – Narrow valves usually found on road bikes. They have a small threaded nut at the top that must be unscrewed before inflating.
Schrader valves – Wider valves similar to car tires, commonly found on mountain bikes.
Many modern pumps are dual-compatible, meaning they can work with both Presta and Schrader valves. If your pump only supports one type, you may need an adapter.
Extend the handle of your pump and ensure all parts are in working condition. Check for any cracks, leaks, or loose components. Some pumps have a lever or screw mechanism that locks the pump head onto the valve—make sure you understand how it works before you start.
For Presta valves, unscrew the small top nut. Place the pump head onto the valve and secure it. A proper attachment ensures no air escapes. If the pump has a locking lever, flip it into place. For Schrader valves, simply push the pump head onto the valve and lock it.
Use steady, controlled strokes to inflate your tire. Avoid pumping too quickly, as this can damage the valve or pump. Most bike tires recommend 30–120 PSI, depending on the type of bike and your riding style. If your pump includes a pressure gauge, monitor it closely. Otherwise, check the tire manually for firmness.
After reaching the desired pressure, carefully remove the pump head. For Presta valves, screw the small top nut back in place. Always replace valve caps to protect the valve from dust and damage. Double-check tire pressure if needed.
