Mega motor madness has been great I've had no issues whatsoever the only thing that I recommend is that they detail their instructions little bit better but it's mostly common sense if you read the book that came with it you shouldn't have any problems it only took me 25 minutes to put it together out of the box me and my son who's 8 years old and very happy
Tip for consumers: This is one of the better sites to purchase dirt bikes and ATVs from they're shipping fee was nowhere near what the other guys were charging and they're all selling the same kind of bikes
