Query: Excellent bike

I bought this dirt bike for my son's 7th birthday. He absolutely loves it. He has rode it every day since. The dirt bike goes pretty fast, and seems to be pretty durable. My son has wrecked on it several times, but both the bike and him were okay. Definitely wear a helmet and knee pads! I think the bike is better suited for a child 7-10. Only because of the size of the bike. He is a small 7 year old, and it fits him perfectly. My nine year old daughter also rides it. I honestly believe a 12 year old would be too tall to comfortably ride it. So far it is the best present I have ever bought him. He LOVES it!
