19 mile range? I weigh 220 lbs. How much do you want to bet I'd get much less???? Come on Henry, give it a real battery!!
My money is on the Neo Volt!! With a 56 mile range, you don't stand a chance!

Put a luggage carrier on top of the battery pod and affix a small generator for in-ride charge - Almost unlimited range! Many Japanese generators weigh only a few pounds so would not affect the handling much, they could still be left running in a suitable space to recharge fully while the rider is in a store, for instance..

This design in a recumbent style cruiser bike ( crank forward posture with a seat even lower) AND a banan style seat which has room for a second passenger behind the first. That would be ideal. Of course youd need a more powerful hub motor but this would be much heavier.

the designer of this design should look at the outrider trike as an example of excellence

Every time someone posts an eBike everyone complains about the price and limitations of the vehicle. The pattern is consistent enough for me to suspect the problem has much more to do with the technology than the companies deploying it.
I doubt there is a bunch of companies sitting around capable of building a perfect ebike but just not interested in all the money that would be thrown at them for doing it.
Most the eBikes I have seen with half decent capabilities are priced higher than you could pick up a motorcycle for.

Looks perfect for downtown but not much opportunity to pedal with only one speed. What about a Sturmey Archer type hub for the front wheel drive so that some gearing would be possible?

Diachi hit it right on the head. For 1800, I can get a decent bicycle and a scooter for when I need to go more than 19 miles.

I find myself wondering what the advantage of this over a standard folding bike with a aftermarket hub motor front wheel and battery setup would be. You can get a decent folding bike for about $250 (citizen bikes), and a really nice wheel/battery setup for about $1400, and it would fold up smaller and be far better for use as a pedaling bike(6+gears). It might weigh a tiny bit more, but it would be a much more practical vehicle.
If I wanted something unique and I was going to spend $1800 I would probably spring for a Yikebike.

3 mph pedaling speed would be faster to just walk home wle

The front wheel is far to close under the rider. This design would have to be limited to slow (like 10 kph) speeds to allow safe emergency braking without flipping over the handlebars. Good compact design for light weight, but it has limitations like all current ebikes do.
