Bafang Ultra M620 G510 motor rotor with detecting sensor for replacement. The motor needs calibration after replacing the rotor, UART motor use our special 961 display for the calibartion and CANbus M620 motor needs Bafang Besst tool for calibration.

The two rotors are the same with sizes; only the teeth are different; The matching third gear for the rotor also changed in 2023;  If your motor was sourced before 2023, then your motor would be with the old version rotor and the 3rd steel gear; if your motor was sourced this year, please check before ordering or buy the rotor and the 3rd gear together.
