Bet the cable is the "gear change", it allows that linear pull arm (attached to chain) go to another pawl and changes the leverage equation.

I just went down the rabbit hole into oddball bikes, and holy smokes, it popped up.
ETA- What I thought were lightening holes are anchor points to mate to the crank arm, so I just accidentally got lucky.

Pretty cool that the mystery part was identified as part of the Alenax!
By chance, I recently watched a video of a similar, but more modern, version called the String Bike.
It's amazing how people keep thinking up this sort of drivetrain and taking it to production, but without the benefit of knowing that these sorts of things have been designed before and failed in the marketplace. The excitement of creating something cool seems to prevent some folks from doing any sort of market research, apparently.

Like oval chainrings, people keep thinking up the same idea and assuming that they were the first ones.

But I'm going to be first in the market with my completely revolutionary wheel re-imagined and redesigned!
I won't reveal the incredible breakthrough I have made, but here's a hint: this wheel is NOT that boring old outdated round shape...
Operators are standing by to take your orders. Don't delay!

That reminds me of another great idea that keeps getting reinvented... the hubless wheel. This is where the there is a huge hoop that is a bit smaller than the rim, and there are bearings between the hoop and the rim. Sure, it looks interesting, with a big hole where you would usually see a hub and spokes, but it ends up heavier and more expensive, etc.
There's a nice, brief BBC article that explains "The magic of a hubless, or more accurately centre-less, wheel is that they aren't actually lacking a hub".
As an engineer, I fully understand the fun of designing stuff and seeing it turn into a useful item. I suspect that's what causes these things to be reinvented time after time. Someone should tell them to check the patent office to see if it's been invented before, or check some old books. If nothing else, they should talk to an engineer and find out that you don't want to actually take a product to production, because that means dealing with customers.

Oddly (or not), this showed up in my YouTube recommendations today. Mostly a horrible video, but from about the 1:30 mark you see how the mechanism works.

I'm also surprised that that the creator of the video didn't just replace the bent screws instead of installing them in a less critical location.

When I worked in a bike shop on Long Island. NY, the Alenex salesman pitched the owner hard and we wound up with a few. I and other mechanics/sales tried to dissuade owner based on mechanical, parts availability and won't-sell reasons. We each really wanted to actually sell one once we did have them, but no takers.
I think the owner made some deal with someone because they all disappeared. I don't think we sold any to an actual customer.
If I remember correctly, there was some type of crazy reverse sprocket/freewheel on the NDS?
Anyone out there actually build one besides me?

I low-key love inventors tilting at windmills. Lots of crazy idea and every once in a while an idea sticks.
