At first I advocated the idea of a "one size fits all" mentality with everyone using 1000 Watts. But now I'm suggesting a combination of a linear constant current powerband combined with a table of values that correspond to overall rider + bike weight. That way if people are of vastly different sizes they can "race" together more equally.



For cargo hauling vehicles the non-linear battery limiting "Power" configuration is better.

Linear power is better for top end. (what I call "Force Limiting")

Non-linear is better for slower speed bottom end. (what I call "Power Limiting")
