I am looking for some help with some weitrd symptoms on a bike conversion. I bought a Bafang G310 front geared hub 250 watts from Aliexpress (£90 plus £40 to get it into the UK}. I bought a £17 controller (linked below), throttle,KT LCD3 (linked below),
I have fitted the bafang into the front wheel of my Raleigh Chiltern and put the controller and batteries in the front basket - currently connected to 36 volt 13 amp ebike battery. Eventually I aim to use 2 x 18 volt 12 amp drill batteries that will fit in the basket
I have been attempting to get the controller to talk to the Bafang -
settings are
P1 - 88 or 176 tried both
P2 0 or 6 tried both
P3 1 or 0 tried both
P4 0
P5 15
C1 05
C2 0
C3 1
C4 4
C510
C6 1
C7 0
C8 is unidentified
C9 0
C10 No
C11 0
C12 4
C13 0
C14 3
C15 4
The controller shows a thr logo when I engage the throttle, walk assist shows the little man walking but the wheel does not turn
- unless I spin the wheel backwards - then the motor gives a tiny kick -
If I have the throttle engaged and apply gentle backwards pressure to the wheel then the motor judders and resists the push
If I hand spin the wheel forwards then I get a speed reading via the sensors in the Bafang. I have also turned that off to see if that makes any difference
I have made four other ebikes but all with mid drives. For this one I just wanted to add an inconspicious motor and hide everything in the tasteful front basket. I am not planning to use any motor cut off brakes as I want to keep the bike as clear of wires as I can.
I have no cadence ring and tried with cut-out brakes but the symptoms are the same
I have spent five days on this chasing around the web and looking at lots of threads on here
can anyone here help me
or...have I bought the wrong controller?
