content: The manufacturer misaligned the metal plate on the wheel bar, so I was unable to put the wheel on at all because the little plastic fitting didn't go on it. Overall, I was expecting higher quality because of the name, but it's a piece of junk. The entire thing is plastic, no real treads like advertised. The old ones from when I was a kid were much better and had more tread. After 1 1/2 hours of trying to assemble this thing, having taken it apart to see where I went wrong, I realized it was a manufacturer's defect!To make this so much worse, this was my daughter's "big" gift from Santa, the one she wanted the most. Now I have a big gift for her brother, and nothing for her. How sad is that!? What a terrible experience. I would recommend getting the Original Big Wheel over this any day...
