I got a couple packs of “ebike” chain that was labelled as 9/10/11s a while back from a friend who got a belt drive after his bike was totaled. I was skeptical but I put it on an electric mid drive 1x9 and human power 2x11 and it seems fine for both and derailleur adjustments seemed normal and unproblematic. I have yet to break any chain in good condition on a manual bike, but the ebike is doing well even in some bullshit load situations after wrecking several generic chains.
