So I bought a TSDZ2B from ElectrifyBike and they kindly pre-flashed it to OSF for me (TSDZ2B OSF v20.1C.5-b Upgrade Motor Kit 250-750 W), with the 860C display. Sadly...it doesn't fit. I tried to put it on a Delta recumbent trike, so not a traditional bottom bracket, and just fit test and it won't work. Completely unused, although out of the box enough to fit-test and find it won't work.
