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
cost
weight

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.

thanks!
