Also, would this motor stall out or overheat on a 3mi 9% grade? I've pedaled up this grade many times without a motor (at about 3.5mph, which equals 125W according to http://kreuzotter.de/english/espeed.htm ). With an ebike I would probably reduce pedal effort by about 1/3.
Trying to answer my own question, https://www.ebikes.ca/tools/simulator.html?motor=MG01_STD&grade=9&hp=75&throt=20&batt=B4810_LiF shows the maximum "never overheat" speed as 3.7mph, with 49% efficiency (Why so low?). Inputs are Bafang G01 std (Photo shows "G20" for this one; how comparable is that to G01?), 169W battery output, 9% uphill grade, 48V battery.
