Review: GREAT DIRTBIKE! - This is an awesome dirtbike for the price! It's so much fun and works great for littler kids. It goes about 20 mph and it works great on our dirtbike path which is up and downhill. The battery last pretty well but best to charge at night. It's so awesome to see the kids zipping around the trail and having the best time ever. It feels really safe and that was a big factor for us in deciding between the gas and electric dirtbikes. I highly recommend this!
Review: GET THIS FOR THE KIDS! - Bought this a year ago for my 5 year old for a Christmas present. 1 year later he still uses this EVERYDAY! Set up was easy. He’s now about 4 foot tall and 60lbs and still enjoys it just as much as the first day! Great product. NO SUSPENSION WHAT SO EVER! Never the less my son tries to jump curbs with it. The speed setting is honestly perfect as we live inside city limits and it can’t get away from him! Perfect “first dirtbike” experience!

### ⭐⭐⭐⭐⭐ Great Quality!
*by P***R on December 31, 2019*

Great Product! My son is 7 and there is a missing market for this age group. Power wheels are slow and boring and for them and bog down with more weight. This is fast enough that its exciting but not so fast that he gets seriously hurt. (We've already taken a few spills) I will say that it is quite heavy and the one time he was unable to lift the bike up off his leg so parental supervision is required. I think it's very small for the age group it recommends. My 12 year old tried it and while enjoyed it as well looked like a giant sitting on it. I was more worried about her being top heavy and falling than my son. With the weight limit I took a ride and I've got to say it I was impressed that it didnt seem to bog down even with me on it. This bike is super easy to assemble. And feels very sturdy and of great quality. The tires are rubber air tires unlike cheap plastic tires and seamless goes over different terrains. However, it does take the full 12 hours to charge the first time and I feel it took almost as long to charge each time after that. My son rides for about 10 to 20 minutes at a time, many times throughout the day and I feel the buttery does last almost all day this way. Overall, this is totally worth the money for many hours of enjoyment and the happiest kid in the world.
