"Schritt-für-Schritt: Ninebot G2D Max Reifen wechseln ohne Verzweiflung"

First things first: The G2D Max has tubeless tires with a sticky self-healing layer inside. That stuff is great for small punctures, but it makes changing the tire a pretty messy affair. Get enough paper towels ready (and maybe a beer for your nerves afterward).

First, the side covers have to go. Behind them are the axle nuts.

• Front wheel: Quick and easy, just watch the drum brake.
• Rear wheel: You’ll need to carefully disconnect the motor cable. It runs into the frame – you have to unscrew the side panel to unplug it.

We recommend putting the wheel on a table. If you're working on the floor, you've basically lost before you've even started.

Let all the remaining air out. Now comes the moment where most people fail: the tire needs to be loosened from the rim bead. It’s stuck on there like crazy.

Our trick: In the shop, we use a C-clamp to squeeze the tire until it slides off the rim edge. If you don't have one, you'll have to use a lot of force (and caution!) by stepping on it. Just don't bend the rim!

Lubricate the rim edge and the tire bead thoroughly. Don't use oils that damage the rubber! Now place one side of the tire at an angle and push it in. For the second side, you'll need the tire levers.

Work your way forward in small centimeter steps. If you try to take too much at once, the other side will pop back out. (Yes, it's incredibly annoying, but it's normal.)

For the tubeless tire to seal, it needs to be pushed against the rim with a burst of air. A small floor pump often won't work because the air escapes faster than you can pump.

Pro Tip: Go to a gas station or use a compressor. When you hear a loud 'pop-pop', it’s seated correctly. Afterward, be sure to check with soapy water to see if any bubbles rise at the edge.
