It was a fun and unique experience to run on for a short amount of time, but most people would get dizzy after a few minutes of jogging on it. The curved platform also turned out to be a bit of a tripping hazard. It was more often used as a sort of swing (could this work on the moon?).
I'm skeptical that the experience on the moon will be much better, especially since the diameter they're proposing is even smaller.

Rowing is pretty full body and doesn’t seem that reliant on gravity.
A tapered cylinder "gravity gym" with adjustable angled walls, and variable speed spinning, could smoothly create much greater "gravity".
Spin gravity would also enable body weight exercises, core exercises, stationary or small area cardio like exercise bikes, VR games, yoga, etc. Even sleeping.
EDIT: I missed this:

Still think it will be inevitable. Far more useful physically and psychologically. "Spinning surface" is a simple challenge, compared to "low-g health deterioration" and "bored to death of running in circles".
Equipment like this might resolve issues with off-world childbearing. Time to "spin up" some space rabbits and see what we get! (Hopefully not tribbles.)
Spin areas will surely become ubiquitous in all low gravity colonies.
Startup anyone?

> would pose technical challenges
That's a very funny disadvantage to call out! "Technical challenges" are how you know you are on the moon.
A stable rotating system would seem to be one of the simplest possible lunar challenges. If it is implemented within an existing environment shell, it could be quite low tech.
> demand substantial electrical energy.
Maintaining rotation in low Earth gravity should be a very low energy process. The only energy loss would be friction at the point of rotation, which should be minimal, and some position controlled weights, for maintaining balancing in the context of human movement.
But the proposed no-tech solution has a great return on investment, and is realistic for early days, or infrequently inhabited outposts.
