They really are NOT for kids, that is the problem. I see kids doing same with golf carts, do they ban them? No of course not. We have them and have for years, ride them slower than most any bike rider out there lol. We just use assist when needed up hills, or when really tired out, they would be perfect for the Fort. But I wouldn't let a kid ride mine, there should be a minimal age recommendation at least and if abused, then they are told at the Fort to not ride them anymore. Would be the same if you saw someone speeding along on a golf cart and kids riding gc's haphazardly which I see all the time at campgrounds that allow golf carts.
