A flat tire on your Razor electric scooter is definitely a disappointment. Luckily, fixing it is easier than you might think. You just need to figure out how to remove the tire and inspect it to decide whether it’s repairable or a replacement tire is required.
In this guide, we’ll walk you through the whole process of fixing a flat tire on different models of the Razor electric scooter.
Check the Tire for Puncture
In some cases, a flat tire doesn’t necessarily mean that there’s a puncture. It could simply be because of lost pressure in the tire due to cold weather or other reasons.
Before attempting to disassemble and replace the tire, you can try pumping it with air until you reach the desired pressure and notice how it behaves.
If the tire flattens again, then most likely, there’s a puncture somewhere. It may not be immediately noticeable if it’s too small, but doing that test should confirm its existence.
For the Razor E100 Electric Scooter:
Here’s how to fix a flat tire on the Razor E100:
Remove the Front Wheel
By using 2 5mm Allen keys, unscrew the axle bolt and remove the wheel.
Take Out the Tube
Disassemble the hub by unscrewing the 4 screws between the upper and lower hub. Remove the inner tube and inspect the tire for puncture.
Fix the Puncture
If the puncture is small enough to be fixed with a patch, apply the patch and install a new tube. If the puncture looks unrepairable, you must replace the whole tire with a new one.
Install the Repaired or New Tire
Inflate the tub, put it in its place, and assemble the hub by tightening the screws. Inflate the tire to the pressure specified in the owner’s manual.
Unlike the front wheel, the rear on a Razor E100 is made of urethane, and it’s tubeless. In other words, if it was damaged, there’s no other way to fix it than to replace the entire wheel with a new one.
Here’s how to do it:
Disassemble the Wheel
Using a screwdriver, unscrew the 6 screws on the deck plate and remove it. Then, drag the 2 screws that hold the battery strap and take it out. On a side note, keep the screws in the correct order because they could be of different sizes.
Then, disconnect the battery from the main module by disconnecting the motor wire connection and setting it aside.
Remove the Motor Housing
Using a screwdriver, untighten the 3 screws that hold the motor housing. Then, untighten the lockout on the right-side frame using a wrench while holding the inner lock nut with another rotation to prevent it from rotating.
Remove the Wheel
Now, you can safely remove the damaged wheel and replace it with a new one. Reassemble the wheel by fastening all the screws you removed. It’d help if you took some photos while disassembling the wheel just to remind yourself when attempting to reassemble it.
For the Razor E300 Electric Scooter:
To tackle a flat tire on the Razor E300, follow these steps:
Remove the Wheel
Using 2 wrenches, take out the wheel and the front axle bolt by removing the locknut, washers, and spacer.
Untighten the 4 screws that hold the hub with a Phillips screwdriver. Remove the damaged tube and check it for foreign objects like nails. If it’s not severely damaged, apply a patch to fix it. If not, you’ll need a new tire.
Put a New Tube
Get rid of the puncture source and put the tube back into the tire. Just make sure that you don’t inflate it too much so that it protrudes outside the tire.
Assemble the Wheel
Assemble the wheel the same way you disassembled it.
Remove the Chain Guard
Use a screwdriver to remove the chain guard by unscrewing the 2 screws that hold it.
Step 1. Use a Phillips screwdriver and take out the chain guard. Keep the two screws safely.
Take Out the Other Components
With an Allen wrench, remove the brake cable. Then, disconnect the brake housing anchor by loosening the fasteners with 2 wrenches. You also need to remove the axle adjuster screws with a 10mm wrench.
After that, you can remove the wheel by loosening the axle with 2 17 mm wrenches.
Remove the Brake Drum
To remove the brake drum, you need a small hammer and screwdriver. Turn the drum counterclockwise and hammer it with the hole. Then, unfasten the 4 screws that hold the hub to disassemble it.
Repair or Replace the Tire
Now that you’ve removed the wheel, you can examine the tire and replace the inner tube. Then, inflate the tube and raise the tire’s pressure to the required number.
If the tire is heavily damaged, get a new one.
Reassemble the Wheel
Put everything back to its place by following the above steps in reverse.
By now, you should be able to fix that flat tire on your Razor electric scooter. You just need to prepare the required wrenches and a replacement inner tube to go through the process with little.
Of course, if the tire is damaged beyond repair, you’d also need a new tire for your scooter.
