One thing to keep in mind is that anything with the range you want is going to be heavy as hell, and no way you are going to pedal normally (which you said you wanted the ability to do). Nothing will turn you off riding a bike normally faster than a super heavy dragged e-bike. You know the old saying "you want cheap and good, you can have one"....well, you want massive range and light weight, you can have one. So maybe you want to think about getting a slightly less expensive e-bike and then buy a nice lightweight regular bike to ride. You can use the ebike pedal assist to get in shape and develop your pedaling technique, and then you'll have a lot more fun riding a nice light regular bike with normal pedaling. plus...you'll satisfy n+1.
