Bafang error 09: Motor phase fault

High severity Service soon

Can I ride home with this error?

Ride with caution. Pedal without assist only if the wheel or cranks turn freely; stop if the motor drags or locks.

What it means

The power wires between the controller and the motor have a fault, so the motor cannot be driven correctly.

Likely causes

  • Damaged motor cable
  • Faulty motor winding
  • Loose or corroded connector

Symptoms

  • Code 09 shows
  • No assist
  • Motor may judder, buzz or feel stiff

How to fix it

  1. Switch the bike off, wait 10 seconds and switch it on again.
  2. Check the motor cable for damage you can see.
  3. Do not open the motor.
  4. Take the bike to your dealer; Bafang's manual says the motor needs replacing.
