Error 08 on your Bafang indicates: Hall sensor error inside the motor.
Stop — motor damage possible — Hall sensor error inside the motor
Symptoms
- Error 08 on display; motor makes grinding noise or won't spin; jerky rotation
Common Causes
- Failed Hall effect sensor inside motor
- Water damage to motor internals
- Overheated motor causing sensor failure
- Pinched Hall sensor wires where they exit the axle
Fix Steps
Step 1: 1. This is a motor-internal fault — cannot be fixed without opening the motor
Step 2: 2. Check Hall sensor wires where they exit the axle — if pinched or cut, repair with solder and heat shrink
Step 3: 3. If wires are intact: the Hall sensor board inside the motor has failed
Step 4: 4. Replace the motor core or the Hall sensor PCB (~$30-60)
Step 5: 5. If not comfortable with motor disassembly, replace the entire motor (~$250-400)
