Flat tires are the worst.
Whether you're cruising through the city or tackling a rugged trail, a flat tire on your ebike can stop you in your tracks. You might be lucky and be close enough to walk your bike home, or maybe you can call for a pickup.
But more often than not, flats happen when you're too far from help, and that’s why knowing how to fix them is crucial.
One thing to remember: if you're walking your ebike home with a flat, keep the flat tire off the ground!
Running the bike on its rim can damage it, which could lead to a much more expensive repair.
If it’s the front tire, lift the handlebars like you're doing a wheelie. If it’s the rear tire, grab the saddle and lift the back end. Either way, keep that flat off the ground!
In this guide, I’ll show you how to fix both tubed and tubeless tires, plus some handy tips to make sure you’re always prepared.
Tubed vs. Tubeless Tires: What’s the Difference?
Here’s a quick breakdown of the two types of tires you’ll find on ebikes:
Tubed Tires
These are the more traditional style, where an inner tube holds the air inside the outer tire.
If you get a flat, it’s typically the tube that’s punctured.
-
Pros:
- Simple to repair using a basic patch kit.
- Generally more affordable.
-
Cons:
- Flats are common. If something punctures the tire, it usually gets the tube too.
- More time-consuming to repair, as you have to take out the tube and patch it or replace it.
Tubeless Tires
These tires skip the inner tube and instead rely on an airtight seal between the tire and the rim, using liquid sealant to plug small punctures as they happen.
-
Pros:
- Less prone to flats, as the sealant plugs small holes automatically.
- Lighter, giving better performance and less rolling resistance.
-
Cons:
- More expensive, and setting them up initially can be tricky.
- Messier and more complicated to repair larger punctures on the go.
Common Ebike Tire Problems
The most common issue for both tubed and tubeless tires is, of course, punctures.
Whether it’s a sharp rock or debris on the road, flats are inevitable.
Maintaining the right tire pressure and keeping an eye on wear and tear can help reduce your chances of getting a flat, but you’ll likely need to deal with it at some point.
Essential Tools for Repair
Whether you have tubed or tubeless tires, always carry these tools with you:
| Tubed Tires | Tubeless Tires |
|---|---|
| Pump | Pump |
| Spare inner tube (carry at least 2) | CO2 cartridges (at least 2) |
| Tire levers | Tire levers |
| Patch kit | Tubeless tire plug kit |
| Ebike multi-tool | Ebike multi-tool |
Having these tools on hand ensures you can handle a flat wherever you are, whether you’re on a long trail ride or just cruising through town.
How to Fix a Tubed Tire
Step 1: Remove the Wheel
First, you need to remove the wheel.
If you have a quick-release mechanism, you’re in luck. If not, you’ll need a wrench to loosen the bolts.
For rear wheels, you might need to shift into the highest gear and disconnect the motor cable if applicable.

Step 2: Find the Puncture
Once the wheel is off, use your tire levers to remove the tire from the rim, then pull out the inner tube.
Inflate the tube slightly and listen for hissing, or use water to find where the air is leaking. Once found, mark the puncture.
Step 3: Patch the Tube
Roughen up the area around the puncture with sandpaper from your patch kit. Apply the adhesive, then press the patch firmly over the hole.
Let it set for a few minutes.
Step 4: Reassemble the Tire
Once the patch is set, carefully put the tube back inside the tire, making sure it’s aligned properly.
Reinstall the tire onto the rim using your hands (or tire levers if needed), inflate, and check for leaks.
Once everything looks good, reinstall the wheel and you’re ready to go!
How to Fix a Tubeless Tire
Tubeless tires are great because small punctures often seal themselves, thanks to the liquid sealant inside.
But for bigger punctures, you may need to step in.
Step 1: Find the Leak
Inflate the tire and listen for a leak.
If the sealant hasn’t already plugged it, you’ll need to find the puncture and mark it.
Step 2: Quick Plug Fix
For bigger holes, grab a plug from your tubeless repair kit and insert it into the puncture using the provided tool.
This will work with the sealant to seal the hole.
Emergency Fix Option: Slime or Sealant
If you're in a hurry or don't have a plug kit, injecting Slime or a similar sealant can be a quick fix.
Just inject the sealant through the valve or puncture hole, spin the wheel to distribute it evenly, and inflate the tire.
This should hold long enough to get you home or to a repair shop.
Step 3: Inflate and Check
Inflate the tire back to its recommended pressure.
If the plug or sealant holds, you’re good to go! It’s always a good idea to carry CO2 cartridges for quick inflations.
Prevention and Maintenance
Prevention is key when it comes to avoiding flat tires. Here are a few tips to keep you rolling smoothly:
- Regular Tire Pressure Checks: Underinflated tires are more prone to punctures, while overinflated tires can burst.
Make sure you check your tire pressure regularly.
- Inspect Tires Frequently: Look for wear and tear, cracks, or any debris that may be stuck in the tread.
Catching these early can help prevent flats.
- Top Off Sealant: If you have tubeless tires, make sure to regularly top off the sealant inside.
It dries up over time, and without it, you’re more vulnerable to punctures.
- Ride Smart: Avoid riding through areas with sharp debris or rough terrain if you can, or at least slow down to reduce the impact on your tires.
Conclusion
Flat tires are part of the ebike experience, but with the right tools and knowledge, they don’t have to ruin your day.
Whether you’ve got tubed or tubeless tires, knowing how to fix them will keep you on the road or trail longer.
Regular maintenance, smart riding, and being prepared can prevent flats and ensure that when they happen, you can fix them quickly.
Now that you’ve got the know-how, go ahead and enjoy the ride—just make sure you’re always ready for those pesky flats!
