My BIL has a couple, both Specialized. My SIL rides a mountain bike style, she loves it, wife wants one now. My BIL has a road bike with assist. They live in a hilly area, as he nears 60 he appreciates the assist occasionally, but her really doesn't like the overall weight of the bike.
I'm rebuilding an old Honda CT90, I seriously considered making it an EV. A lot of good options on the power and control, the issue came down to the batteries and packaging. I wanted it to look somewhat stock, no way with a big block of batteries you have to hang off of it somewhere.
Dennis, I've bought multiples for our Family to have at a couple houses; one is pavement/cart paths and the other is Lake setting with different terrains.
