Bosch eBike 523006: Speed sensor is not working correctly.

Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
Speed sensor is not working correctly. A reduced drive unit power may therefore be available to you. The speed is likewise incorrectly displayed. For 523006, Bosch's user step is: Check the rim magnet and spoke magnet, if present. Then restart your eBike. If the problem persists, please contact your specialist dealer. If the same code returns, preserve the display and stop repeating resets.

- Do not open powered components or bypass sensors. Stop riding if assistance, braking, lighting or controls behave unpredictably, or if there is heat, smell, damage or moisture.
Safe checks you can perform
- Preserve the code before changing anything
- Apply only Bosch's published user step
- Use recurrence as the stop point

Evidence: Bosch eBike Systems — official fault code 523006
- What the official step decidesPossible
If “Speed sensor is not working correctly.” clears after Bosch's exact step, only the current condition has cleared; no failed part has been proved. If 523006 returns, the documented user branch is exhausted and the recurrence becomes the evidence for service.
