How to choose the right SpeedBox for your e-bike with a Bafang motor?

STEP 1: Communication Protocol / Display Connector
Unplug the display connector and check if your e-bike uses UART or CAN communication.
Click on the correct option.

STEP 2: Number of Speed Sensor pins
Remove the motor cover and check on the label whether the Speed Sensor connector leading to the e-bike frame has 3 pins, 4 pins or 8 pins (motor M200, M410, M500, M510)
Click on the correct option.

STEP 3: Bluetooth / SpeedBox App
If you want to pair your e-bike with the SpeedBox App on your smartphone, choose the option called "B.Tuning."
