They're so well done. Sadly, he doesn't do them anymore because Youtube's algorithm doesn't make it worth his while. Evidently, he gets the same traffic & revenue from a 10 minute video reviewing "stupid bike gadgets" into the camera as he does for spending a month building a cool bike jump and editing together one of those amazing videos on the playlist.
If youtube rewarded evergreen stuff like that instead of cheap "reaction" videos, it'd be a much cooler place.
I watch photography videos on YouTube, and camera review channels consistently have far more subscribers than channels who make content about taking photos. (Or at least they did in the past - in recent years camera tech has really matured and interesting releases are much less frequent).
I think people just like gear.
edit:
Actually the comment the creator left on the video is almost purely AI and is just as yuicky to read: "There are lots of questions about runaway Reevo mode, and it's a fun topic. Let's go deeper. First of all, I did add a "PAS Timeout" that turns off PAS after a few minutes, and is selectable in the menu. If you set this up from my Github repo, that feature is active. A lot of you also suggested a weight sensor on the seat, but that would disable pedal assist if you stood up out of the saddle, which is when you would need it most. Another suggestion was the dead man switch. That one would work! This is all fun to think about, so keep the ideas coming. I just MIGHT get another Reevo for myself."
