Getting a flat tire on your scooter can put a damper on any ride. You can't ride on a flat, and sometimes you're far away from home and pushing a scooter with a flat tire many miles to get to the local shop isn't really an option. Even though Chinese-made scooters can be difficult and confusing to work on, with a little know-how and the right tools, anything can be fixed. Carry a spare tube with you and learn how to change an inner tube on the fly so you can get back on the road fast.

Set your scooter on its centre stand and weight one end of the scooter so that the flat tire is elevated off the ground. Weight may be difficult to find on the road, so get creative. Any object that weighs more than about 9.07 Kilogram and fits on the seat will work.
Loosen the axle bolt of the flat tire using a socket and socket wrench. On most Chinese scooters, like those made by Yumbo, Verucci and Shenke, you'll need a 17mm socket to loosen the axle bolt. Refer to your owner's manual if yours is a different size.
Remove the axle bolt and slide the wheel out of the fork or swingarm.
Wedge a tire lever between the tire and the rim. Pull the tire lever down toward the hub to partially separate the tire bead from the rim. Slide the tire lever around the rim to completely separate the rim and tire bead.
Pull the flat inner tube out of the tire. Inspect the inside of the tire to be sure there is no debris or sharp objects still inside that may pop your new inner tube.
Fill the new inner tube partially with air using a handheld pump. This will help prevent pinch flats when you reinstall the tire bead by making sure the tube doesn't get pinched between the tire and rim. Insert the valve of the tube into the valve hole on the rim from the inside, then gently push the tube up into the tire.
Reset the tire bead by pressing it firmly over the rim by hand a little at a time. If at any point the tire becomes too difficult to push over the rim, insert a tire lever between the tire and rim, then pull upward away from the wheel hub. The tire should set fairly easily.
Fill the tire with air using a handheld air pump. Be sure to fill it to the recommended tire pressure printed on the sidewall of the tire (usually 14 to 19 psi) to avoid further flats.
Slide the wheel back into the fork or swingarm and slide the axle bolt into place. Use a socket and socket wrench to tighten the axle bolt firmly.
