2025 BAFANG BBS Can-bus Version
Controller Upgraded
- Battery Cable: XT60 (same as UART) and a New Battery Communication Cable. If you use a BAFANG battery with communication and a BAFANG display, you can view other battery information through the display or the BAFANG GO+ App, such as battery temperature, total battery capacity, remaining battery capacity, number of cycles, discharge time, voltage for the cell, etc. If you use other batteries, you can ignore the communication cable, as you cannot view other battery information (the experience is the same as UART).
- 1T4 Cable: Can-bus version. The new thumb throttle can operates more accurately through the new 1T4 cable. The deeper you press, the more powerful assisted you get. At the same time, the speed limit on the display can be applied to Throttle mode and PAS mode.
- Speed Censor: Can-bus version. The new controller can collect speed information more accurately and apply the data to the controller program to improve the output power. You will enjoy more smoother power.
- Gear Sensor: Same as the UART version
- Front and Rear Light: We add the rear light cable for the mid drive, We don't need to weld the rear light with the front light anymore.
Bottom Bracket Size Measurement
Same as the UART Version, we add the 73mm screws pack and spacers as the options. If the width for the bottom bracket is not 68mm you may need order extra screws or spacer. If you are confused about this, you can contact us.
Chainring Options
BAFANG recommend 44T chainring. If the cassette on your bike is above 9-speed, you can choose 42T chainring
Can-bus Display Options
If you want to reset the parameters through the display, we recommend you to choose DPC010 or DPC080. They are perfectly compatible with the new Can-bus Version. If you do not need these functions, other displays EKD01, P860ML, VD61, VD618, VD03 are more cost-effective choices. Among these options, VARSTROM recommends EKD01.
Battery Options
If you use a BAFANG battery with communication and a BAFANG display, you can view other battery information through the display or the BAFANG GO+ App, such as battery temperature, total battery capacity, remaining battery capacity, number of cycles, discharge time, voltage for the cell, etc. If you use ordinary batteries, you can ignore the communication cable, as you cannot view other battery information (the experience is the same as UART).
