He speaks a lot in the video but does not seem to say very much in terms of actual facts.
At one point he says that, when starting pedaling, the Avinox motors take a 100-180 degree crank rotation before they kick in, while Bosch is only about a 10 degree rotation, so the Bosch is more responsive. I have yet to ride an Avinox, but that is a pretty stark contrast between 10 degrees and over 100 degrees, and I am surprised that I have not heard the point raised before. Anyone with Avinox and Bosch motors care to clarify the truth of the matter on how fast the motor kicks in when you start pedaling?
At another point in the video he says that the Avinox power delivery determination is cadence based, whereas the Bosch is torque based. I can't imagine that to be true as all high end mid-drive bikes use torque sensors to determine rider output, and scale the motor power delivery correspondingly. I think he may have been using sloppy languaging to describe a different "feel" in how the motor delivers the power, and different output characteristics for a given rider input. What he really may be feeling is a 800% support ratio vs. a 400% one. To him, that gives a feeling of a sort of autopilot on the Avinox where as long as your legs are moving (ie. cadence) the Avinox delivers a lot of power, while the Bosch requires more leg power, which he is calling "torque" and he interprets that as better "feel" for what the rear tire contact patch is doing on tech climbs. He doesn't address how dialing back the Avinox to eco or trail mode changes the picture.
I would genuinely like to see some other content from him on the topic that makes his case in a more clear and concise manner, and has less of a sort of "I'm telling you the real deal, but the other guys are just blowing smoke" attitude.
