the interest is not the gimbal but the rollers of the chain which are replaced by ball bearings.

Without protection, their usefulness (not that they rotate on their axis during the contact with the gear), the longevity and the exceptional yield remain to be verified. To judge the efficiency of a technology, aesthetics is not enough.

In 1898, we already knew how to make a bike without chain "Acatène" https://wiki.tontonvelo.com/index.php/H ... 98_environ

There is no reason that ball bearings will not hold if they are waterproof and calculated for the load. What must be seen is the contact of the ball-bearing transmission and not the gimbal in itself where the load is transmitted by friction.

why talk about gimbal? there are not any !

there is a conical engenage in front of ... a bevel gear behind, but no gimbals!

everything is rigid!

You're right, you only need a cardan when there is a shock absorber (and again, it depends on the geometry of the suspension).

the interest here on this bike is the exceptional transmission efficiency associated with a variable speed drive.
