We bought this bike for our 6 yr old for Christmas. While it is small in size, it makes up for it in speed. I don't think I'd want my 6yr old on anything bigger going the speed it gets (faster than me on a regular bike going uphill). He has LOVED this bike so far and so does everyone in our neighborhood. The older children (8-12) can also ride it and have said how much they like it. It's perfect for his age/height. Would definately recommend! Esp. if you have a good yard/neighborhood to ride it in.
