Motor rpm important?
I'm considering a 36v front hub kit from BMS for my first build. I plan to use a 36v, 10.4 ah bottle battery. One motor is 36v/500w with an rpm speed of 328rpm; the other motor is 36v/350w with a speed of 201rpm. My bike is a Jamis commuter with 28"wheels; total bike and rider weight (less the electronics) is about 180lbs. Does the motor rpm really matter to me? I'm looking for 20mph and 15-20 mi unassisted. Would using a 48v/500w motor gain me anything? Sorry to be such a nimrod; I've been searching this forum for about a week but I still have questions.
