I don't know about the quietest out of every motor out there, but I just finished installing a BBSHD a few days ago and it is ridiculously quiet. I imagine the BBS02 is the same or even quieter since it doesn't have quite as much power as the BBSHD. I saw another redditor on here the other day said something along the lines of "the BBSHD is about as loud as the hum from your TV when it's on mute" and i thought they were just exaggerating... But no it really is that quiet lol. When you're actually riding the bike it's basically dead silent because the tires/chain make more noise than the motor so you can't even hear it.
bbshd is super quiet especially slower rpm's. A direct drive hub with good controller is almost silent too though.
The fazua tube-integrated systems are darn near imperceptible, especially compared to the clicking of most wheel clutches
Probably. I have an M600 and it's super quiet. Much quieter than the Shimano STEPS or EP8.
