Interesting.
I'll try to get my hands on it.
Now you got me interested because look at how it looks:

I place my bet on the H700 gears: they're for the human powered drive. Because of the consistent emphasis on how the motor shifts gears to suit cadence, and because of the single external gear cog provided. (Assume that's what "look at how it looks" refers to.) I see the "bicycle news" reports that talk about how the gearing is going to make the motor work better, so there's clearly some confusion on one side or the other.

Typical cover plate design for geared motors...

Can anyone confirm this resembles the housing of the Xiongda? As in that case I'm doing it all wrong.

Yes, I confirm that the principle is exactly like that.
The only difference is that the 2 speed motor has a special clutch system in the lid.

From he Bafang newsletter (see attached screenshot): Their 2 speed motor has 2 gears for pedaling cadence and not for the motor itself.
