Extrapolated, that means you will kill your knees on this bike. Doesn't matter if you're fit or not, low cadences kill knees. The way to keep knees happy is high cadence with less effort, not the opposite. If a high cadence can't be achieved, that's a dealbreaker for me.
Second concern: When coasting on this bike, are you really resting your legs? My guess is no, in the same way standing up takes more effort than sitting down.
Viable concerns, and totally explainable. If you see any of his other videos, you'd see he uses higher cadence when ascending, and lower on decents. This guy is in amazingly good shape. If his knees can handle his low cadence,...only time will tell. He doesn't always use low cadence.
As to resting when not pedaling, it's the same as my Micro PedalFlow. I have no issue with rest when I ride it. It's all about conditioning.
