Looks like a BBS copy but don't think it is .
It isn't a current AKM mid drive because AKM/Aikema Suzhou are the parent company of Tongsheng Suzhou and any AKM motor now is the same as a Tongsheng.

It may though be a copy of an earlier Aikema TS drive motor from 2019.
NEW CRANK DRIVE 48V 250W AKIEMA | Endless Sphere (endless-sphere.com)

The akm 100/128 hubs were sold using the Q monika so Q100/Q128 etc ,etc . It is possible the QM is a copy of the original AKM MD- P250.

At the time it was assumed the AKM MD P250 was a TS motor but it may have also just been a cadence motor like the BBS.

One can only assume the AKM wasn't succesful as in 2019 the company acquired Suzhou Tongsheng Electric .
