I think I'm going to go electric on it with a restrictor or something to keep the speed down.
He'll start just riding on back roads with me on my "town" bike, to get a feel for how it works before going on any real rides, but it's all country roads out here, so I can get us just about anywhere on the side of a dirt road.
Even at 5 or 6 years old, I see no reason we couldn't visit people on the bikes.
