  • Save up for a better bike
Color: Upgraded Q20-1500W 48V 20AH
i bought this bike as a 16 year old and it came with a bent front sprocket so we told them that then they sent us a part that we did not need to fix it and told us i could keep riding it and it was safe little did i know that the pedal assist was still in working action so the pedals started to spin freely so i got off the bike and didnโ€™t realize the pedal's were still spinning so it randomly shot off in front of me and completely totaled the bike and there is no refund ... show more

I have purchased two of these bikes for my 12-year-old and 14-year-old sons. They have a lot of fun on them! The customer service team has been great if ever we had a question or needed to order something.

  • Missing glasses & Bike lock. Please send them!
Color: Upgraded Q20-1500W 48V 20AH
The media could not be loaded. I bought two of the upgraded dirt bikes for my son, and I have not opened the second one yet. However here is what it looks like out of the box, my 12yo was able to set it up all by himself within 1 hour, by scanning the code and watching videos. I am just upset that the bike did not come with the pair of glasses or bike lock. It runs really smooth so far. He rode it today for about two hours. Brakes are very hard to squeeze so it slows down very slow not rapid. But it prevents it from skidding. Runs 37 mph ... show more
