Flat Tire Repair on an Electric Bike

Flat tires, as unfortunate as they are, are a regular part of riding a bike, and even more so while riding an ebike, as wicks are heavier and tend to pick up things more often. Sometimes you can be lucky and go months without a flat, sometimes you can be really unlucky and get multiple in a week. Your Tower Electric Bike has tires that can help mitigate flats a bit and sealant inside of the tubes. But even with these, flats can still happen, and this guide will show you have to change the tube inside your tire!

Here is a video of the process:

Here are the tools needed for this:

  • Tire Levers
  • Bike Pump
  • 15mm/18mm Wrenches
  • Shop Rag or Cloth
  • New Tube

Here is the process:

  1. First, using either your 15mm or 18mm wrench, remove either the front or rear wheel from the bike.
  2. If there is any air in the tire, press on the valve pin to let any excess air out.
  3. With the tire flat, pull the tire edge/bead away from the inner lip of the tire all the way around the wheel so the tire is loose on the rim.
  4. Take one of your tire levers and hook it underneath the bead/edge of the tire in the wheel. You will have to pull the tire back to reveal this edge.
  5. Once the tire lever is under the bead of the tire, lever it towards the center of the wheel, pulling that tire edge out from inside of the tire.
  6. Push the tire lever and rotate it around the wheel, pulling the tire edge outside of the wheel. It may be a little stiff at first, but as it gets around, it gets much easier.
  7. Once one whole side of the tire is unseated from the tire and is exposed, pull the old tube out and dispose of it.
  8. Wipe the inside of the tire to check for anything that may still be poking through. If anything is poking through, the cloth/rag should catch on it. Anything you find, remove so it does not cause a new flat.
  9. Once you have cleared anything that could cause another flat from inside of the tire, take your fresh tube and open it up.
  10. Pump a little bit of air into the tube, just enough so it takes a shape and is not flat.
  11. Take the tube start where the valve hole is and put the new tubes valve through the hole in the rim.
  12. Tuck the rest of the tube into the tire until the whole tube is inside of the tire.
  13. With the tube now tucked in, it is time to reseat the tire into the wheel. Start on top of the valve by pulling the unseated section of the tire back and tucking it into the rim.
  14. Continue tucking the lip of the tire into the wheel all the way around. Take care not to get the tube stuck in between the tire and the rim, or you can pinch the tube and tear it.
  15. Once you get to the side opposite the valve, it may get a bit stiff to tuck the tire back in. If it is too stiff to move, go around on either side of the tire and pinch both sides of the tire and push down into the rim. Continue doing this, getting closer and closer to the section of tire still needing to get tucked in. As you get to this section, it should be much easier to get that tire tucked.
  16. Once the tire has been tucked back into the rim all the way around, it is time to air up the tire. The recommended PSI to inflate to is 30-65 PSI.
