Just seen it - awesome!
I wonder how it feels riding it. Can imagine there is still a bit flexibility
in the frame - but who knows?
The wheelbase is quite short and the seat high. So it’s supposed to be agile
and turning quickly but still easy to ride because of the high COG?
What about doing something similar / parametric using rod end bearings and
lightweight steel tubes - like the front suspensions on formula racecars?
With the threaded end you can still fine-tune the geometry or just replace a
part with a short or longer version if needed.
There was a rumored development of a Moulton spaceframe „MDev 90" version with
carbon tubes being pulled together by tensioned wire running inside (somehow
like a spoke):

Even this kind of frame could have been scaled easily by changing the tube
sizes.

Anyone remembers the picture of that prototype some years ago? I found it
amazing but there was no additional info and nobody thought it could work ...
Well now here is finally a project page with some videos and specs:

Kudos to this guy. I am still dreaming of a parametric frame construction
made of tubes and 3d-printed lugs - and this comes close.
