As a small super micro OEM we had the opportunity to try one from the Italian Distributor and have been completely disappointed by how it looks and works.
Terrible BB and feeling, terrible chainring eating chains and always derailling with the same offset and chainline issues as a BBS, and more...
The torque sensor works cool, but I can say that there's something strange about the pedal feeling with the Crank/spindle level, that seems related to the torque sensor system. I mean something wrong about the mechanical feeling not the torque control response that is otherwise very good. So If you like to pedal and have an unchanged pedaling experience, that's for sure not the right system.
The New cranckdrive launched at last Eurobike seems otherwise a way better product, offering an universal mount, while even bafang moved to an OEM dedicated middrive....
Anyway, The BBS1 at similar power levels is significantly a better system IMHO....
Cheers
