Thoughts on best power meter

[Spicule]

@tbar. Wouldn't any power meter system that measures force at the pedal/cranks/spider/spindle bottom bracket only be measuring human output on the strain gauge if the motor is a hub system that is only applying force directly to the hub/wheel and not at all on to the chain and chainrings?

@Spicule yes, I believe so, and that was my hope / plan. However, I struggled to find a crank arm / spider power meter that was compatible with my ST2S. And I did not want to put ”roads” cleats on my Stromer. Garmin now has the Rally-line of pedal-based power meters, so those will probably work. I got side-tracked since I really didn’t want to spend something approaching $1000 on this project.
