I don’t have a “real” E-bike, but I have a Panasonic power-assist bike. In Japan it’s called the “Gyutto Annys” which is Japanese-Italian which is supposed to sound European. It has a kid’s seat on the back, and a basket on the front. I got it for my wife to run errand and shuttle our daughter around, by I probably use it more than she does. It’s very heavy, and very rugged, but can climb pretty much anything while carrying a kid on the back and a load of groceries on the front.
When I bought it about 6 years ago it cost 120,000 yen, or a about $1100 at the time. So far it has been a durable and reliable bike, they only issue is battery durability. The original battery last about 40% as long as it used to. A replacement battery costs about $300, and I’m probably going to have to get another one soon.
