Ok, it was a rhetorical question!
About the biometric feature, I have to give a shout-out to Rakesh and Falco motors who promoted a version of that a year ago, Sept 2014.

I am really enjoying the multiple operating systems that new wireless technology is bringing to ebikes.
My short list fav:
1. NuVinci Harmony Hsync : operator dials in a variable cadence setting. Power assist is adjusted by controls in the rear transmission, nu vinci gear, AND/OR the assist level of the motor.
2. Auto shifter - Shimano + Steps.
3. Operator interfaces with motor setting controls. (ST2, Falco, EM)
4. Falco and Easy Motion Biometric control (Heart rate).
