What watt?

How is it possible that Bafang list their H500 series motors to have the max torque of 80nm for 250/350/500 watt variants?
if I have 48 volts what’s the difference I will notice between 250 and 500 watts?

if there is no torque increase what do you gain by replacing a motor with a new one of higher wattage e.g. 250-500 watts.

power is rpm x torque, torque needs amps, and rpm increases with voltage.

So for the H500 it looks like it's just related to increasing battery voltage. The H550 is probably a different winding - so gets more RPM for the same voltage.

That's just my assumption based on what I've read here over the years - not an expert on hub motors or windings.

Just as long as it can run on 52v and 40amps it's ok
With a throttle. Is that too much to ask ?
