Abnormal speed signal from speed sensor
The speed sensor is delivering an implausible speed signal, and the system disables assist as a tamper and safety protection. Typical triggers are a wrongly placed magnet or sensor — and also speed tuning attempts. Mounting sensor and magnet correctly and taking a short test ride normally clears the error.
