I bought this for my 3 yr old son's birthday. I was hesitant at first thinking maybe he should be older but it is perfect for him. He figured out immediately how to use it completely. We have a large, open back yard so I don't really have to worry about him running into things. He loves it and cries when we make him get off. It is good quality and much cheaper than most from a toy store.
Still going strong after 2 years of hard use. Easy to assemble and a hit with the grandkids.
