Zstar Pocket Bike

[Rattler]

Anybody know anything about them? My brother-in-law gave one to my boys for Christmas, and we're trying to get it going now that the snow and gravel are gone.

We have it running, but can't get any speed out of it, even with our youngest on it. Mind you, our boys are both bigger than average, but they can push it on their feet quicker than it puts along at full throttle (not you, FT!)

Does anyone know where I can go for basics of troubleshooting these things?

The product page states that it should be able to do 55km/h, so my first thought would be to check if there's any throttle/speed limiter on it since it's designed for use up to 14 years of age. Couldn't find any good source though.
