Review: Bought for an 8yr old kid - Very good product. I bought for a 8 years old kid and I was afraid to be too big bike. However it’s a perfect size for this age. Speed is not a big concern son can easily manage that. Very easy to assembly and I feel quality in all materials used. I recommend this bike
Review: Great first electric dirt bike! - Got it for our small 9 year old boy for Christmas. Its the perfect size for him and he'll have a few really good years with it. Im 143 lbs and I rode it and it went fast. My tall 5' 3" 13 yr old was able to ride it too at full speed. Assembly was really easy. All you have to do is put the handlebar and front wheel on (had my brother do it lol). It DOES NOT feel like a little ride on toy either. Great buy. Will update later if anything changes or not 😊

### ⭐⭐⭐⭐⭐ Great bike
*by A***R on December 27, 2025*

So to start this is a cool bike my son loves it,made his Christmas wis come true. This bike was easy to put together and charge. He road it Christmas morning and had a blast. Then Friday afternoon came and this happened, the sprocket on the rear wheel just spins when the throttle is twisted to go. I looked this up and some people say it's common for these,there is a fix for it but I'm going to reach out to razor first seeing as I just bought this and they should replace the rear wheel at there cost hopefully they do. Other than that it's a cool bike
