Just looking at the variety of options available for shifting, derailleur, IGH, gear box and ones like the above one would think that there is a need for a one type fits all solution for shifting gears on bicycles.
That is far from the case however but for the more extreme circumstances that a derailleur based system goes through on an off road type bicycle while the above might work the need for an all new frame and system will keep it in the niche marketplace for quite awhile even if a major manufacturer picks up on it.
The frame design and lack of it ever being able to be a belt drive will keep it out of the cheap bike/commuter/touring market which in reality is the lions share of bicycle sales worldwide. Got to like the young man's engineering initiative and creative ability however.

Innovative for sure. But complicated. And I can't help but think of how Haibike did away with their Bosch-powered idler gear on their last generation full suspension mtb's once Bosch themselves went to a more traditional front chain ring design on their newest motors.
This designer and builder must have thousands of hours in his design and he has my complete respect. But I personally feel that the rear frame dropout is not beefy enough for long term mountain biking and related jumping, etc. In fact, I can't help but think I am seeing a crack in that rear drop out, at the 11 o'clock position, near the through axle and going to the outer side of the drop out. Hopefully, it's not and it's just a piece of dirt or something.....
