This is an amazing design.

The bottom photo is an early motorcycle design from the 1930's.

I can't read the website, but it looks pretty cool.

Looks interesting, I don't like having all of the electronics on the rear swing arm like that tho.

I know that on my electric motorcycle I was able to shift the center of gravity lower and it handles much better making it feel like a much smaller motorcycle even tho the curb weight is about the same.

It is amazing what 23,000 euro will buy these days. The center hub design has been around for decades notably the Bimota Tesi motorcycles and the recumbent Nevacar. It could use a Vetter nose section.

The front body section is for scooping air for the battery cooling.
I'm sure if we rode one, our opinion would be more pro than con.

Any vehicle in that price range is expected to have excellent riding manners. I believe there is room for improvement in the air flow without compromising the design statement based on the original design in the final photo. Form plus function equals elegance.

The batteries and motor on my electric motorcycle are both cooled by a single server fan with a 3" inlet, it doesn't take much to keep them cool.

It would be interesting to see up close the batteries in that Johammer bike.

without full front and rear fairings to encapsulate the driver, motorcycle aero sucks.

Note, all the smoothness is for naught.

I tend to prefer naked bikes just to keep it simple, or vetter style full enclosure/recumbant. Something that looks streamlined sitting still, but isn't when you add a rider is not well thought out aerodynamically.

(and yes, I recognize the previous post as a prelude to spam)

Doesn't look like it was designed by someone that rides motorcycles to me.

Lots of artsy touches, but I'd like to know if it really works.
