BBS02 locking open spanner

I'm not sure that you can buy an open ended tool, that deals with both lock rings on one tool.
Years ago, when I first fitted my BBS02 kit, I bought a kind of open ended hook tool that allowed me to tighten the inner lock ring. I also bought a separate open ended tool that tightened the outer lock ring. Neither were ideal, as they tended to slip and I ended up with grazed knuckles. The outer lock ring tool in particular, didn't allow a great deal of scope for tightening, as it was too thick at one section to get enough clearance between the lockring and motor housing.
These days I use a full multi-purpose tool, like the one in the link, and just take my crank arm off when I need to tighten the motor, or gain access to some of the internals. A much better option IMO, and no more grazed knuckles
Bafang multi-purpose installation tool
BTW, a crank pulling tool is a handy addition for when you want to regrease the final drive!
Edit: I'm sure you could also get away with just removing the pedal and slip the ring spanner along the crank to tighten the lockrings.

I managed to dig out the tools I was on about, just to show you how awkward they were to use:
The inner lock ring hook tool was difficult to get enough leverage, as the shape made it awkward to hook on the cut-outs properly. The hook would slip out frequently, causing a few expletives.
The outer lock ring tool (and I was correct the first time) was just too fat in parts to squeeze between the lock ring and motor casing. This meant you only had a tiny window, where the tool was thin enough to fit on and turn.
The all in one tool that I use nowadays, just makes it easier, even after the requirement to remove the crank arm or pedal.
