You wind it like this, it's going to take 420 metres of 0.5mm enamelled copper wire which will cost me £10 plus maybe several hours, of which I have plenty at the moment. Worth a try considering the motors are toast otherwise.

What about a BionX D with external controller?

viewtopic.php?t=90037

Motor weights just 4kg and with a 20s battery should easily reach 50km/h.

I don't know if you would be happy with the maximum torque, I assume 60-80A phase current should be a sensible limit and that's not for continous useage.

You can try the Simulation, the BionX D is included in the motor list: http://www.ebikes.ca/tools/simulator.html

I also don't know which controller works well and which doesn't.
