View Full Version : motor/controller recommendation for bike similar to zero fx 7.2?

14 July 2018, 1048
I'm trying to put together specs of a bike with similar performance specs as a zero fx 7.2, which has 78 ft lbs torque and 46 hp. I understand AC20 is a popular, but expensive option for this type of build. I'm wondering if the ME-xxxx motors have a contender as well.

factors to consider:
pack size
efficiency/heat generation

I also understand that the motor performance can also be limited by the controller, battery, and even the gauge of wire you use. So I'm also looking for some insights there.
