Neat technical article, but it's unclear to me how it's relevant to utility cycling/this community. Recreational mountain biking is sport, not !micromobility.
All bikes have hubs, but I guarantee no utility cyclist cares about how much backlash theirs has. An article about internal gear hubs or dynamo hubs might be relevant, but this? No.
This is very much like posting a deep-dive article about locking differentials for 4x4 rock-crawling into a community about hypermiling and then trying to defend it by saying "well your first-gen Honda Insight has a differential, right?"
Some people skateboard on the street to get to work, so skateboards can certainly be micromobility. As such, an article about, say, a new e-skateboard with better range would fit just fine. An article about how to do a kickflip, on the other hand, would not because kickflips have nothing to do with using a skateboard to actually get places.
