Bafang M400 /M300 /M420 harness EB-BUS 1T4 / 1T3/ 1T2/ 1T1

Bafang M420, M300, M400, M620, G330, G360, G510 UART EB-BUS cable/bafang display wire for M400 M420 M300 M620 motor

There are two types of EB-BUS cables, one for UART motor and the other for CANbus motor, for UART motors, there are 4 types EB-Bus cables, and for CANbus motor, there are another 4 types cables, please check our pictures before placing the order. 

UART motor has a round green connector for the display while CANbus motor has a triangle green connector for the display.

Bafang motor main harness 1T3, connecting the display, a pair of e-brakes, cable length: 1.2m;

Bafang motor main harness 1T1, connecting the display, for coaster brake system, cable length: 1.5m

Bafang motor 1T4 EB-BUS cable, connecting the display, two e-brake grips, and one throttle.

If your original Bafang M400 motor is with 1T1 EB-BUS and you want to add a throttle function for your ebike, please choose the 1T4 EB-BUS. The throttle function only works after starting with pedaling the ebike, please note.  

If your Bafang M400 G330 motor is with 1T3 EB-BUS and you want to add a throttle function for your ebike, please choose the 1T4 EB-bus. The throttle function only works after starting with pedaling the ebike, please note.  Important tips: the throttle for the Bafang M400 motor only works under load with the pedal speed reaching 10km/h.

The display connector is with 5 pin round connector which means for UART protocol; if your display is wiht triangle 5 pins connector, then it is a CANbus motor and you will need CANbus EB-BUS cable, please note.
