Okay, I just have to ask, what the heck is up with the wheels? Is that the Model A and the Model B and they have different suspensions? Did the plus-sized guy sit in the front one and the lighter guy in the rear one? Is there a "straight wheels/whomperjawed wheels" lever in there?

My opinion on the usefulness- it's pretty limited, being half-bike half-car means it has the disadvantages of both in this case.

Pedaling my Worksman front-loading tricycle around was eye-opening. It's similar width, but what that means is that you pretty well take the lane whether you want to or not. But, you're riding 12 mph instead of 20 mph, so you're that much more of an obstacle rather than a vehicle. Not a good feeling, and best dealt with by judicious choice of routes.

When I see something like this that's electric-assist, I always get the impression that they meant to do better, but accidentally invented a heavy slow vehicle and are trying to make up for shortcomings with electric assist. It'd be kind of like if you went to buy a car, and they had a 6,000-lb model with a booster motor in back- you'd think "Why the heck would it need that, unless they got the real motor underpowered for the massive weight?" IE, it comes across as a negative, not a positive.
