Show me one.
I do not own an EBike and currently have no reason to buy one. I just think they will replace motor scooters/mopeds in a lot of places in the USA.
I rented a pair when I went to Acadia National Park in bar Harbor, ME. The park does not allow gasoline motor vehicles to drive on the carriage roads around the park. They do allow bicycles and E bikes because they do not make noise. They were perfect for that situation.
I asked the guy who rented them what maintenance they required. He said virtually nothing.
