  • Underpowered engine
Color: Blue
Horrible bike. My skinny 6 year old can barely get it to accelerate. It will not go up any sort of incline.

  • The small button on the handle bar must have the cover on it for the engine to start.
Color: Blue
Can't get the engine to run with the choke fully open. Assembly was pretty easy. Decals were the hardest part. Will be great fun for great grandchildren.

The media could not be loaded. Bike came very fast and wasn’t to hard to put together my son loves it

  • Gutless and dangerous
Color: Blue
Not only will it not pull itself faster than I can walk (walking beside it at full throttle) it shoots a jet of flame out of the exhaust which is aimed at the front tire?! Returning it immediately. So thankful I tested it before Christmas.
