As I have considered switching from a rear hub to a mid-drive and been reading up on torque v. cadence systems, it's clear to me that there is a need for both. not every rider is suited to a torque sensor, even though they say it's more like riding a regular bike. If you have a knee problem that makes initial pressure getting started a problem, or ( like me) have a medical issue where muscles give out the more you ride, a cadence based system can be better. One that has 9 levels of assist with the ability to program those levels to give more
precise control over just how much motor each level produces. if you are perfectly healthy a torque system seems like the right choice. i'm glad we have both options.
