Lectric Flat Tire Repair

We are going to show you how to change a flat tire on a Lectric folding ebike. The bike comes in stock with 20x4.0 tires in the front and the rear for the axles. It has 15mm in the front and an 18mm sized wheel in the rear.

Removing the Front Wheel

Before repairing a flat tire, we must first remove the tire from the bike. To remove the front wheel, we will be needing a 15mm wrench to loosen the bolt in the fork. Once that is done, the front wheel will fall right off. If the tire still has a considerable amount of air inside, we will have to let air out to make it easier to do the next steps. After which, we will have to remove the valve cap and then use a tire lever to peel up the tire and expose the yellow rimmed strips inside. We will loop all the way underneath the lip of the tire to loosen it, and then take the tube out.

In removing the front wheel, we encountered some difficulties with the axle bolt. When we first tried to loosen it, the axle was so tight that when we turned the nut it also turned the whole axle instead of the nut just loosening. In our experience with working with different ebikes, the majority of problems come from either the front or rear axles.

Replacing the Tire Tube

Always remember that when repairing a flat tire, you should figure out what caused it in the first place so that you won’t get another flat tire when you install a new bike tube. For the next step, you will have to inspect the tire for this object and, if there are any, remove it. To do this, you will need to use a piece of cloth and rub it on the inside of the tire slowly and feel whether it will snag in any object that punctured the tube. If you find any, pull it out using a pair of pliers.

To replace a new/fixed tube back to the tire, we recommend starting with putting the valve through the valve hole. From there, we can tuck the tube all the way around inside the tire. We also must make sure that it is not pinched anywhere. After doing this, we can then inflate the wheel back to its recommended pressure which is 20psi for this variant.

Reinstalling the Front Wheel

The repaired front wheel will just easily slot right back into the fork of the bike. One both sides, we must make sure that the hook is on the outside of the axle with the bend going through the hole. We will then have to tighten the bolts to secure the wheel in place using a 15mm wrench.

Rear Wheel

If the flat tire is in the rear wheel, it will take a little bit more work to replace it compared to the front. On the rear left side of the bike is the bike brake caliper, and there is a part above the bracket that is threaded into the frame and loops over the rear axle. We will have to loosen the bolt in and slide it out to take the whole wheel off. This must be done on either side of the bike and in the chain guard which rests right above the axle. Once all the bolts are taken off, it will be just like in the front wheel. We will have to follow the same procedure in removing the tube and replacing it.
