Guys, lets not forget that mini-e only have 6FETS. No way you can have the same performance with that as with a 18FET Xie based controllers. The mini can drive a bike up to 75km/h period, thats about 3500-4000Watts of power to get it there. You can push it further but you will overheat it very fast and thermal management inside will kick in to save the controller.
Rix, the bike does accelerate hard up to 40km/h then it goes slower up to speed. I think that this is because you reach the kV/V of the motor. If I would have 48V then probably a hard acceleration to 45-50.
Today I did a run with fresh battery 42V hot of the charger and the speed was 70Km/h oops

It does 50km/h easy (OVS 0) and with the help of OVS(overspeed setting 5-7) setting you can get it up to 70

Upped the battery current to 160DC Amps and got 6,2KW of power. I think I will keep it this way for a while. I am not a speed junky, I am acceleration addict
Stritzky, pretty easy, just press down the metal holders with a small screw driver and remove the leads from the housing. (oh you fixed that already)
