What You’ll Need to Fix a Bike Flat

Step-by-Step Instructions for Patching a Bike Tire
1. Remove the Wheel
Shift gears to the smallest cog (rear) or smallest chainring (front), then release the brake if needed and remove the wheel.
2. Deflate the Tire Completely
Press the valve core to release any remaining air—make sure the tube is fully deflated before removal.
3. Pry Off the Tire
Insert a tire lever opposite the valve stem and gently lift the bead over the rim. If you're unsure about safe tire removal, check our detailed guide on how to remove a bicycle tire. Work around the tire with additional levers if needed.
4. Remove the Tube and Find the Leak
Take out the inner tube. Inflate slightly and listen for hissing or submerge it in water to spot the leak.
5. Prepare the Area
Sand the area around the puncture lightly to create a better bond. Apply glue and wait a few seconds until tacky.
6. Apply the Patch Firmly
Press the patch down firmly for 1-2 minutes. Ensure it sticks securely without bubbles.
7. Inspect the Tire
Before reinstalling, check the inside of the tire for debris like thorns or glass.
8. Reinstall the Tube and Tire
Insert the tube’s valve first, then work the tire bead back onto the rim carefully.
9. Inflate to the Correct PSI
Use your portable pump to inflate the tire. The Woowind BP188 offers precise PSI control and fast inflation for all bike types.
10. Test and Ride
Give the tire a quick squeeze to ensure firmness, spin it to check alignment, and go for a gentle test ride.
Pro Tips to Avoid Mistakes When Fixing Flats

Avoid pinching the tube when prying or reinstalling the tire.
