I have recently purchased a bafang 750 watt conversion kit on my wife's trek fs4 sportster gravel bike
Anyway the kit installed fine ..
44t front chainring and speed and geaR sensor with dpc18 control.
My issue is that the pedalling motion is not fluid like it was half of the pedal revolution it is a struggle to use your feet to turn cranks .usually I have to put one foot under pedal to lift it .the second part of the stroke the pedal moves easily then the stiffness returns on the next half of the stroke...
Thumbthrottle works correctly .
It does this in all pas modes
In pas 0 mode with motor off the cycling effort is unpleasant with the pedal motion being so stiff halfway then easy peasey the other half.
I can't ride this thing like this ...
I even ordered another bafang motor installed it and the same pedalling issue is there...
I removed 2 links from chain when I installed it 10 speed Shimano cassette with index levers
Had to adjust Shimano shift cable after gear sensor install
44t front bafang ring vs 42 t trek small front derailleur
Any suggestions? Programming issue ?
