I rode about 10 miles to the nearest barber shop this morning. About half way back, I'm doing around 30mph, and suddenly loud noises, lots of shaking, and I come to a very wobbly, but fortunately safe, stop. This is what I was looking at. The engine came right off the frame. My first thought was that I hadn't properly torqued the mounting bolts and the nuts had shaken loose and fallen off. Upon examination, I realized that what happened was that the mounting studs had sheared right off flush with the engine. Don't anyone even try to tell me that it's my fault for overtightening the mounting bolts. I tightened them enough so that I could be sure they wouldn't come loose. If they hadn't been made from such cheap metal, they wouldn't have broken, period. These things are not safe because of the poor quality of the materials they are made from. Don't risk your life trying to save a few dollars by riding one of these things. I am definitely finished trying to polish a turd. These things are dangerous and there is no way to make them not dangerous, except to melt them down and turn them into yard sculptures. My parting advice: Take all your cheap crappy Chinese junk metal and put it where it belongs, in a trash compactor.
