You should try to ride a few ebikes and compare. See which ones you would prefer.
Absolutely, positively the right answer. We frankly don't know enough about the OP to recommend or endorse a bike, but we DO know enough to say the following:
o If you're new to ebikes, you have no idea what you really want and
don't want in an ebike. And the only way to find out is by testing a
variety of ebike types, not by reading.
o An ebike is a complex purchase. Let the folks at the bike shops you visit educate you on the ebiking practicalities that really matter day to day.
o Fat tires look cool, but they come with a lot of downsides, as
@harryS just mentioned. If you don't need to ride in mud, snow, or loose, dry sand, I'd think twice.
o How will you get the bike serviced after purchase? You should know the answer to that before you buy online. Best bet is to locally if at all possible.
