I haven't bought an ebike because in Abalammer they're considered a motorized vehicle. Everywhere I could legally use one, I could also drive my truck. We don't have a lot of atv access on public land.
In Mississippi, they seem more lenient about atv use. But, my understanding is an ebike is the same as an atv there as well. Can't use then in walk-in only. I've heard but never directly read that some National Forest land has trails that are foot traffic only, excluding even pedal bikes.
All that being considered, I'd buy a Rokon before I bought an ebike because a 212cc gas engine will whup any electric motor you can put on a bike, whoop it hard, and whoop it for less money than the motor and that lithium battery.
All that said, I have no beef with them. I think the laws should be made with primary consideration to what the habitat can stand. If the biologists think a parcel can handle ATV use, cool. If they think it can only handle bootprints, cool. If you can access it, cool. If you can't, I feel for you, but this is the best time and place to be a mobility-restricted individual and I'm sure you can find something to do.
