the picture of the mid section clearly shows it's not made from a single piece.

That is definitely a unique design. This will be a conversation piece on the trail for sure. Bike design is evolving quick.

It may look pretty, but it also looks extremely fragile. The point where the latticeworks join the main components looks especially fraught, with sudden changes of section.
During the last century, bicycle design reached a level of perfection, for reliability, and, fishtailed connections between the main components and the connecting tubes was found to be the best solution.
My conclusion is, that this frame will break, and as its not weldable, will very quickly become scrap.

Labor (and material) intensive. As 3D metal printing moves forward, this will become a curiosity.

not as nice as my original Klein

So what does the frame weigh?

Luckily all that machining waste is completely recyclable.

It's definitely eye-catching, but definitely not a bike for muddy conditions.

Ooh, ooh! Keen-o-jet! A billet bicycle frame. Wowsers, Bruceski. I'm stoked. And only 150 times the cost of my Wally World Granite special, too! [Disclaimer: OK, so it was only 149.68x the price.]

Would like to see this sort of beautiful design enhanced by FEA-driven inputs and printed out in metal. This could result in a more organic looking trellis that is structurally strong in precisely the way in must be to face the specific forces it encounters on the trail. Then, it could truly be "made in one piece". And, it might possibly be cheaper to manufacture.
