Servicing a BPM hub - some quick advice needed!

[catsnapper]

I'm trying to help out a local rider with a BPM 350W powered e-bike here in Barcelona. I was sure there were several threads about dismantling one on this forum or E-S, but much as I look I can't find them

It's a while since I played with a BPM, so I'm struggling to remember basic things, like how to remove the cover -even which way it turns

Any quick reminders or links will be much appreciated!

The BPM1 has screws around the sideplate on the drive side, so very easy to open. The BPM2 has the screw-on sideplate, which is a bit more tricky. You need to make or buy a tool to turn it.
