A good, entry E-Bike for a large man?

[Electric_Fish]

Hey, guys! To be clear, large in my case means 6'3" and about 285 lbs. I'm pretty new to the e-bike scene, but I spent all day yesterday looking at bikes. Unfortunately, I'm still not sure what I should go with. I intend to use this to get around my city, using sidewalk where possible, and streets when not. I know I want to be upright and value comfort above all else. I know I don't want to spend any more than $1,700, and would definitely prefer to spend less if I can. Mainly because I don't want to feel like I've wasted a huge investment if I can't use it as much as I like (bad knees, occasionally lock up when pedaling, which is the reason for e-bike assistance, and sensitive pelvic bone).

Some bikes I was looking at are:

The Ariel Rider W Class - I fell in love with the visual design of this thing. Main concern with this cruiser is whether it will be functional and comfortable on streets and for my height. And the price, of course.
RadCity 2019 - This looks like a pretty decent bike, but will it be more or less comfortable than the Ariel Rider W for my height/weight? The assistance goes to 20 mph, is this enough? (honest question, haven't ridden a bike with a speed gauge before, no idea what 'normal' is)
The Aventon Pace 500 - Seems like a lower watt battery but a higher power bike from what I've read? Up to 28 MPH assist, but once again not sure how good this is as an upright bike for my weight and height. I can't find max weight rating anywhere.

By no means are these my only options, so please offer any suggestions you guys have that might be a good fit for me!

I'm in a different weight category, so please take the following as a piece of common sense.

You might want to consider Rad Wagon (350 lbs payload) or similar models by other brands.
Cruisers like City or Ariel W are designed for a rider "up to" 280-300 lbs. This is approximate. Dynamic loads (bumps, curbs, potholes) with the rider already at the limit could result in loads exceeding the design limit. Besides, you might want to put something on the rear rack - cold/rain clothes, repair kit, security chain, not much, 10-12 lbs total, but it all adds up.

20 mph is fast if you are not in a hurry (read - late to work)
