    How to increase the Power of a 250W hub motor

    Thanks Trex, under the crank area on the Power Cruiser is a compartment with lots of wires and connections.I think the controller is in a zinc type box which has been sealed with silicone. It definitely has no label. I think that the motor windings will take a much higher current, but what...

    How to increase the Power of a 250W hub motor

    At last, Hooray it is a BLDC, Brushless motor, 3 medium wires and 4 thin ones. IF the motor assuming a nominal 250W can take the maximum current from the battery we are talking about 6.9A from a 36V supply. If tne windings can take 48V.but only 5.2A, what is the maximum for the controller? I am...

    Pedelec Comfort with Full Suspension

    Flecc, thank you for a detailed reply. I was hoping that once I get more power out of this 250W motor, that I would not have to pedal so much, as in my previous 1000W super byke,combined with a softer suspension. I have set the rear coill spring to minimum, but have not noticed the difference.

    How to increase the Power of a 250W hub motor

    Trex thanks for your response, I am confused, photographs I have seen of crank motors look small in comparison with a hub motor, how is torque acheived, different windings, high power rare earth magnets? 10 gears, does the crank drive through a normal derailleur?
