    I ordered this for my 6 year old son who is a little over 4ft tall and about 70 pounds and he fits on it perfectly with some room to grow even I can ride it at 5’2 and 180 pounds and it still rides well with me on it

    Perfect for 4-7 years old learning to ride. Battery lasts about 35 mins of going non stop. No shocks is my only complaint but my kid doesn’t complain about the way it rides. Fun dirt bike for a kid to learn on, without giving a parent a heart attack

    Impressed with the quality compared to the cheaper model. Bike is about 2in taller. I bought this for my 6 yr old. I don’t know what they were thinking when they came up with the 13 yr old minimum age, unless the kid is a skinny midget, the bike will go about 2mph with a 130lb, 13 yr old on it. My son is roughly 50lbs and the bike goes fast on concrete, struggles in grass lawn. Bike needs more torque. But looks good and well built. $398 maybe be a little high given the bike struggles with a 50lb kid on short but thick lawn grass. I think my son will get a couple of years out of this bike. I would not buy for anyone older than 9 or 10 yr, and definitely not for a 13 yr old. If a 13 yr old can’t handle a bigger bike they are better off finding something else to ride.

    Everything about this Christmas present was better than advertised! Was worried it wouldn't be big enough. Perfect size. Was worried it wouldn't be fast enough. Perfect speed. Was worried it wouldn't be durable. Built like a tank! If I didn't know it was electric, I'd swear it was the quietest gas powered mini bike...

    Do not buy this dirt bike. Even fully charged it would not go up a moderate incline. When I tried to return it, they charged an absorbent restocking fee.
