I would guess that ebikes are also being ridden, even where they aren't allowed, by responsible people who don't do anything to draw attention to themselves. Im sure more ages are riding them but they don't stand out and they have the type that look like bicycles. I would say they've probably been near me and I didn't notice them.

For a while the E Bike conversions, front wheel with a motor on it, on cruisers were popular. Now the popular choice with the kids are the electric fat bikes, they have pedals but look almost like a dirtbike.
