Hardtail frame for M510 (M500/M600) XC build

Apr 21, 2023
I am planning a Bafang M510 build with a hardtail frame, preferable 17" aluminum for 27.5" tires and combine it with a front suspension between 100mm to 120mm.
It should be robust enough for trail riding with tiny jumps.

I have found a few possible frames, but I am new to building a whole bike from scratch and would appreciate your thoughts and maybe even experiences on them:

From their website, the name of the frame is AQL29MUS-02-M
Supposed to have only 2.5kg, maybe the smallest size.
Frame size 16″/18″/19″/21″

Would it be possible to mount a M510 into M400 mount with an adapter plate or are they very different?

Are there more (alu hardtail) frames for M500/M510/M600 that I have not found, maybe sources other than Alibaba?
