Anyone have one of these for their kids? If so, how do you like it? We have had one for my grandson, 5 years old, for about a year now, and it is one tough little two stroke. Already have had to replace the electric starter, brakes, and the plastic is cracking all over. While the engine and drive train seems to be solid, there are problems with the other parts. Of course, most of the problems are caused by a very active novice rider who goes everywhere on the farm - rough terrain and rough riding. No racing or jumping, of course, but he really gives it a hard time. I'm surprised it has survived this long.
