I am glad you enjoy your BIONX.
I bought Tioga bike /Canadian Quebec company/ equipped with BIONX SL drive for my wife .
What I noticed right away is how incredible light this ebike was.
I got used to my 1000W DD throttle EPLUS as my summer commuter and when I tried BIONX for the first time I could not detect any motor assist until I chose level3.
I got used to smooth silent EPLUS power so much that initially I was disappointed with BIONX, but when I realized how incredible light BIONX drive is
/even with 10Ah battery/ I said WOW.
BIONX no doubt is incredible efficient, even after 34km ride /no hills ride/ in level 4 my wife was unable to discharge 10Ah battery until cut off.
She was able to reach 31km/h sustained with zero wind on flat, tires at 40PSI warm but not hot but it was all, plenty of speed for her
BIONX is very intelligent computerized drive with many parameters adjustable, most of them only by dealer who have interface driver/disc/ I guess.
For example I am sure torque sensor sensitivity can be adjusted.
