I have this same PROBLEM! I have a family member that just rolled it because of the over steering at a low speed because it just takes off on you and you have to muscle it back into place. the steering is crazy easy and makes riding with one hand just a after thought. I need to find out what causes this. They did end up in the hospital with stiches and laid up for 2 weeks over it. Im a bike mechanic and cant find the problem. everything is tight and straight! I even put new rims and tires on it. Anyone have anymore IDEAS?????????
