Look like a bike, but can you really ride it

It looks like a bit tighter position than the Strida (which is a neat
idea--for an urban dweller--which I am not).

Also the handlebar pivot angle for the vintage bike would be...... odd,
to say the least. Ridable, but I doubt very efficient. Or enjoyable.

If you found one in your attic, it would probably be worth $25,000.

I had to look at it twice to decide which side would be the front one
for me.
Then I noriced the seat, and I got it.

I love that frame as an excellent simplification of the split diamond
into a singe triangle. But questions definitely arise about the
steering geometry...
