To all eBiking Wolf Toothers: Your moment has come.
Wolf Tooth direct mount chainrings for Shimano eBike motors have a 55mm chainline and are compatible with all Boost and Super Boost bikes that use the Shimano EP8, E8000, and E7000 e-bike motor splines.
That gives Shimano pedal-assisters a Wolf Tooth option, which comes in 32 and 34t sizes and, of course, with Drop-Stop teeth.

Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ and 12-speed KMC chains. Use Drop-Stop B for all 9, 10, and 11-speed chains or 12-speed SRAM Eagle, SRAM Flattop Road or Transmission (T-Type), KMC, Connex, or Wippermann chains.

But what about riders cranking other mid-drive rigs?
Wolf Tooth doesn’t stop at Shimano — it also dropped direct mount rings compatible with TQ motors found on Trek ebikes like the new Fuel EXe. These come in 30 or 32t.

Prices for the eBike rings are on the upper end of Wolf Tooth average. You’ll pay $85 MSRP for each unit. Like all of their chainrings, Wolf Tooth manufactures these in the United States.
