You'll see a lot of claims of very high milage out of these little Chinese wonders. Some might be fact, some fancy but in all honesty, I doubt there is a good average number that will apply. This is due to the varying degree of mechanical aptitude among the builders and the way the engines are asked to perform. I have one with over 1800 miles on it and a couple with 500 plus. You'll get more input here from others with many more miles to claim. I ride strickly for pleasure and some local errands. There are those who ride their bikes daily and some who rely on their bikes as their sole form of transportation. Those folks will have much higher milage to report.
