Hi iv got a Bafang mid drive motor in my bike, want to know what one it is, iv got a display screen iv looked on but can’t see on there which one it is can someone point me in the right direction please, and also I need a program cable, mine is a 3 pin wire, hope someone can help me

Hello and I want to ask you a question, did you check the motor itself? Most of this info is on the motor, and getting a program cable is easy on Amazon. But, this is where you start getting into warranty issues if you start messing with the program. Did you purchase the bike new or buy it used?
This is a Bafang Issue ,they changed the Control Program from "UART" (programable) to "CANbus"( non programable)
immediate problems; Non programable, Wheel size @ 28" , Max speed @ 37 mph illegal in most places , run-on after you stop pedaling VERY DANGEROUS !, Very Jerkey feeling motor response not smooth to ride.
Dose Anyone have any updates on the M620 Ultra Motor issues?
