This was delivered Friday, my son rode it Saturday and today. He paid for it himself and was so excited for it. It said it goes up to 18mph. It only went to 15, even on S. The bracket for the back wheel was uneven and rubbed against the tire. My husband fixed it.
Today, as he was riding at 15mph, the whole system glitched and the back wheel completely locked, causing my son to lose control and hit a curb and fall. And now the back wheel makes a clink noise and will lock up. My son said the screen went glitching, and then black and everything shut off. And it was fully charged. He's quite upset about this. But now he is not able to ride it, and it has to go into the garbage. A waste of $160.
