Nowadays, more and more people choose to ride. Whether it is going out to play or going to work, scooter are a fast and convenient way to travel. However, the occasional minor problems of scooter are also impossible to start. Now I will introduce you to the quick repair guide of electric scooters and solve 7 headaches in an instant.

1. Every time I make up the inner tube, I just put it back in again

If the hole in the inner tube is on the inside, the cushion band may be misaligned, causing the inner tube to be cut by the spokes; if it is on the outside, there may be some small and sharp foreign objects in the outer tube. Use your fingers to carefully explore the inside of the tire, find the foreign body, and remove it.

2. Frequent flat tires

Inflate the tires more. [Especially for road cars, you may wish to hit the recommended maximum tire pressure.

3. The wheels are squeaky

There may be loose spokes. If the tension is balanced, the sound may be caused by a slight collision of the spokes that cross. Lightly lubricate the intersections and wipe off excess oil.

4. There is a noise when pedaling

Tighten the crank bolts. If the crank is still squeaking, remove it, apply a layer of grease to the shaft core, and reinstall the crank.

5. The flywheel is rusted

A small amount of rust will not accelerate the wear of the flywheel, so don't worry too much. In general, using a little more oil can prevent continued rust, and the chain will wear away the rust when riding.

6. When using some gear ratios, pedaling appears to jump

There may be something between the flywheel pieces. If you can see mud, weeds, leaves, branches or any foreign objects stuck in the flywheel, dig out. These things prevent the chain from engaging the flywheel normally. If there is nothing, this flywheel may be worn. This phenomenon usually indicates that the chain and flywheel need to be replaced.

7. Screams when braking

Wipe off any dirt or cleaning agents left on the rim. If that doesn't work, sand the brake pads with sandpaper or a file. Still noisy? Need to release the brake pads and adjust toe-in, that is, let the front half of the brake pads touch the rim first. This is a simple thing for a car shop, and novices may take some time.
