    No freewheel on new BPM 2 hub from BMS battery

    Forgot to mention that I verified that no wires are shorted when I made test by hand. I do not know exactly how these motors work, but I would have expected that when gears are not engaging the only resistance to rolling would have come from the axle bearings. But I may be wrong.

    Hello Awol. I will follow your advice and hold before sending it back. It is the newer model with the casing held by screws so it is not a bear to open. I was told on another forum that the problem might only be that the motor has to be sort of 'broken in' for the freewheel to operate in a...

    Thank you Kirstins for confirming that the motor should freewheel. BMS battery is trying to convince me otherwise. Thank you also Alan for your ideas. I have checked and no wires are touching , as the motor is presently not powered and the wires are not connected. Yes I could have tried to turn...
