Highest tooth count for BBSHD chain ring?

I run a 52t Lekkie Ring on a Bafang BBSHD but that is the largest chain ring Lekkie makes. There are higher tooth count chain rings advertised for the BBHSD but I've tried a few and they can't seem to get the offset correct. Is anyone actually running a chain ring higher than 52t on a BBHSD? If so I'd like to hear the details.
I run a 56T on my fat 20" tire foldable w/ 7-speed freewheel. (The short fat tires offset the tall chainring just a bit). I've tried the same setup on my 26" beach cruiser but it just didn't work so good, so my 54T does the trick) I also use spider adapters make a dual front chain rings, adding shorter torque-minded chainrings.
If I am in in hill country or sense any 'powertrain lugging' or want more torque, I just pull over and switch. You have to pay attention & use your gears to keep your motor spinning fast and If you experience any torque fall off, lugging or suspect heat, take it easy and gear it down.

Hmmmm.... The chainstay wouldn't be a problem but I see what you mean. I've cracked a couple of Leckkie Rings when in first gear pulling hard so I'd like to go back to a steel ring with lower cadence but need to maintain or improve offset. (Pics are old 5-speed freewheel. Current 6-speed freewheel doesn't change much.)

I'd have to go out and check my parts shelf again because I think I have almost the same ring you're running. Can't remember if the adapter hit the housing or what it was, but I couldn't make it workable. Links to the one you are running?
You might want to try running a 1500 watt hub may help chainline and combined with a BBSHD hill climbing is effortless.
