**Hijack Alert!!**
Interesting project. How do you control the speed with a normal twistgrip? By which I mean, my glee throttle controls the rev range from idle to redline, and the gears transfer that up the speed range. So my speed range is 6x throttle movement. Your motor is direct drive, I take it, so the entire speed range will be taken up with one fistful of "throttle", effectively making it 1/6th as "responsive" as mine. Are you programming in ramps for steady take up and a "full bore" setting at top end? Intrigued.
