Medium severity Service soon

Can I ride home with this error?

What it means

The speed sensor is not picking up the wheel magnet. Assist may continue, but the speedometer reads 0 and assist may cut before 25 km/h depending on gear.

Likely causes

  • Wheel magnet moved or missing
  • Gap between magnet and sensor too big
  • Sensor cable damaged

Symptoms

  • Speed shows 0
  • Assist cuts early

How to fix it

  1. Check the spoke magnet is in place and passes close to the sensor.
