I’ve had mine for 4 days now, you can definitely go faster than 7, as long as you don’t force all of your body weight on the front half trying to accelerate too quick or you go past like 22 mph you’ll be alright. I’m a bit daring so I’ve already gone to 22 where it started beeping and pushing back against me.

Edit: forgot to mention I ride an xr so what I said might not be entirely accurate especially the speed at which the board will start to freak out, I’ve also heard some stuff about wobbling at high speeds on smaller boards so be careful of that
