Step-by-Step Guide to Repairing a Puncture on Your E-Bike

Step 1: Prepare Your E-Bike

  • Find a flat, stable surface to work on.
  • Power off your e-bike and, if possible, remove the battery to avoid accidental activation of the motor.
  • Mount your bike on the repair stand to elevate the affected wheel.

Step 2: Remove the Wheel

  • Shift to the smallest gear on your e-bike to make wheel removal easier.
  • Use the multitool to loosen the axle nuts or quick-release skewer.
  • For rear-wheel punctures, carefully disconnect the motor cable if your e-bike has a hub motor.

Step 3: Deflate the Tire

  • Fully deflate the tire by pressing down on the valve. This step prevents damage to the tire or tube during removal.

Step 4: Remove the Tire

  • Insert a tire lever under the edge of the tire and pry it away from the rim.
  • Use a second lever to work around the rim until one side of the tire is free.

Step 5: Locate the Puncture

  • Remove the tube and inflate it slightly to identify the puncture. Submerge it in water and look for bubbles if the hole isn’t obvious.
  • Mark the puncture spot with a pen or marker.

Step 6: Patch the Tube

  • Roughen the area around the puncture with the included sandpaper from your repair kit.
  • Apply the pre-glued patch firmly over the hole and allow it to set for a few minutes.

Pro Tip: If the damage is extensive, replace the tube entirely with your spare.

Step 7: Inspect the Tire

  • Check the inside of the tire for sharp objects like glass or thorns. Remove any debris to prevent future flats.

Step 8: Reassemble the Tire

  • Insert the patched or new tube back into the tire.
  • Starting at the valve, push the tire bead onto the rim, using tire levers if necessary.

Step 9: Inflate the Tire

  • Use the portable pump to inflate the tire to the recommended pressure (usually printed on the tire sidewall).
  • Ensure the tire sits evenly on the rim as it inflates.

Step 10: Reinstall the Wheel

  • Carefully align the wheel back into the frame. Reconnect any motor cables and tighten the axle nuts or quick-release skewer.

Step 11: Test Your E-Bike

  • Spin the wheel to ensure it moves freely without wobbling. Reattach the battery and take a short test ride to confirm everything works as expected.
