So I have a original Sondors fat bike that I am upgrading. Everything is in place and turns on fine, but it seems like there are a few issues:
Process:
So the first thing I did was replace the "guts" of this new 750W hub motor into the case of the original 350W hub on the wheel. All went good and its back together. I am not sure if its possible something is wrong with this, or if that even is possible to cause my issues?
I installed everything and plugged in all connectors. Display turns on fine and motor spins like it should.
Issues:
Display shows battery voltage, but NOT the green battery bar at all! Voltage is currently around 54 volts but no green bars.
When using throttle, the MPH, ODO, and the Watts display never change from zero! Even riding a mile or so it all stays at zero.
PAS 0 seems to be full speed PAS 5, when 0 should be OFF, lol.
No other weird noises and the power seems good, but something is off. I contacted the vendor and even adjusted many of the P settings on the LCD to known good settings but none of this changed anything. Eventually I asked for a replacement controller but that seems to be doing the same thing.
Parts:
35amp 36-52v KT Controller
KT-LCD8H USB Color Display
Thumb Throttle Sondors 6 pin HIGO plug
48 - 60v 750w Bafang geared rear hub motor
L3 52v 20.3Ah Triangle Battery
Any help??
