BBS02 in a threaded BMX bottom bracket?

I'm currently interested in converting a bike that has a BMX frame. The bottom bracket is listed as Threaded BMX, BSA 68mm

Some of that sounds good (threaded, BSA 68mm) and I'm trying to parse what the BMX bracket will mean for putting in a Bafang BBS02 mid-drive motor compared to the JIS I know it works well with.

Any experience or thoughts?
