Foldable bicycle design has mysterious pedal assist tech

Jetsonesque!

I can't see how the pedals move the wheels. Is it really science fiction?

Could be the same way as these:

As for braking, it could have back-pedal brakes - quite common in the eighties on mainland Europe.

My own bicycle has 8-speed internal hub gears, and roller bearing brakes. These could easily be hidden inside the discs.

Totally goofy. Look at the steering geometry; about 8 inches of scrub radius! (Oy vey!) You'd be articulating in the middle more than steering the front wheel.

With the steering axis a couple of feet under your privates and the handlebar a couple of feet northeast, it doesn't really matter how you make the wheels turn. Oh, and I wonder if brakes were considered important?

That's where your privates come into play. Synergy!

Do the make it in a tandem version?

Bike looks good on picture. Where is the real model though? Any videos?

What makes a bicycle ridable is geometry, and properties called trail and rake. Not sure if this bike will be stable.
