I have an ebike with a Shimano motor. Not suggesting that over any of the others, but my impression is that it's a little cheaper. After you get one, learn about the batteries. I've been wondering how much the replacement batteries would cost with those bikes that use proprietary batteries. My bike has a bog standard battery, and a new replacement would be very expensive. Fortunately, you can get rebuilt.
A lot of them come with kickstands. Because they are heavy, I would worry about it falling down and damaging something.
This is like any other bike, go to some shops, and try some bikes. They are quite spendy. It could be just the thing to get your wife to come along, I wasn't riding, now I am.
Good luck.
