What’s the crack with bullittbike.de and the pinion ebullitts? Are they modified bullitts with a different motor/crankset housing?

Yea, it's a version that only they sell, it's equipped with the 6-speed Pinion gearbox.

They modify the frames in-house to take Pinion. Also offer a shorter or longer version of the Bullitt bed.

Yeah they do them themselves.
For domestic light use, overkill.
For couriers, just add a rear wheel motor (a good one) and you have the most dependable bike right there.
For home heavy use, yeah pinions ime are less prone to sudden implosion like igh are, but still aren't as efficient as a regular cassette /derailleur setup, and cost a lot more. Trick though!

The shell they use isn't a steps or bosch shell, its only for pinion afaik.
