Thanks for you answer. Unfortunately it does not help.
I do not need external speed sensor because my motor has internal speed sensor.
I know it works because I see pulses on the white wire when I turn wheel by hand in forward direction.
However display does not show speed while wheel is spinning freely.
What setting I have to adjust exactly? I do not see any relevant setting in the description.
---------------------------------------
no setting . i think . only external,
if it dose not influence your usage , no need to care about this,
if you want it to indicte, u need the external speed test sensor .
IT is a rule, when motor sliding down to the hill, the display will not indicate speed,
so we need a speed test sensor to test speed outside,
----------------------------------
u can connect ur white wire (inner speed test wire from motor ) with the white wire of controller from us
it will work as same as the external speed test sensor
