A 60-75 pound fat tire folder is pretty awful as a recreational ride on pavement if you're used to riding a lightweight bike. This one was fun on packed sand om the western shore of Lake Michigan, but that's one day out of the three summers that I've owned it. It was just kind of heavy riding on the county highways in Door County. It's a commercial bike, but there are no showrooms. You work on it yourself or find am indy mechanoc. Battery/motor are generic. In fact, it has a second battery.
This is my converted Downtube, on a skinny model's diet. I've put a very small battery under the seat, good for about 13 miles, enough to get to the picture spot .. It's 30 pounds lighter. Much more fun to ride. As a DIY bike, I'm responsible for everything on it.
