Does it looks like power curve of BBS02B?
We can use it for better understanding what's going on, and for fine-tuning for specific modes.
For example - if you want to save yours Nuvinci N380, let's limit current below 23A on 36V systems, to be below Max.Continious.Torque of this gentle IGH.
Am I...
I'm sorry in advance of my, may be stupid idea, but will try:
What about using kind of adapter to shift pulley-ring from Nuvinci to 56.5-59mm beltline that goes from BBS02?
It can be DIYed in some skilled service with lathe machine.
I'm far from reality, because didn't see bbs02 or N380, just...
