How to Pump Up Your Mountain Bike Tires for Optimal Performance
To pump a mountain bike, follow these steps: first, attach the pump head to the valve of the tire. Then, manually adjust the pressure gauge on the pump to match the desired PSI for your tire. Begin pumping the bike by pushing and pulling the handle up and down until the pressure gauge reads the appropriate number of PSI. Disconnect the pump head from the valve and quickly replace the valve cap before hitting the trails.
