I have a pair of Chinese mini bikes I bought my grand kids a few years ago and they both run fine, they love them. My grand daughters has a flat now but other than that no issues. I do store them over the winter with Stabil Ethanol treatment in them.I wish we would stop that ethanol BS, it isn't helping anything enviornmental. It just harms engines, robs power, and decreases milage. ( by decreasing milage it wastes more fuel and actually causes more emissions, It alsoi has other bad emissions they don't tell you about.)

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
