514001
Bosch eBike 514001: The internal speed sensor is not working properly.
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
The internal speed sensor is not working properly. The speed may therefore not be correctly displayed to you. The output of the drive unit is likewise limited. For 514001, Bosch's user step is: Check that the rim magnet is firmly secured to the valve. Then restart your eBike and check the display after a short ride. If the problem persists, please contact your specialist dealer. If the same code returns, preserve the display and stop repeating resets.
Safety first
Stop and check this first
- 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

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

Symptoms and causes
Probable causes · in order
- What the code establishesConfirmed
Bosch identifies 514001 at Drive unit: The internal speed sensor is not working properly. Keep that meaning scoped to a Bosch eBike system and the exact code shown.
Evidence: Bosch eBike Systems — official fault code 514001
- What the official step decidesPossible
If “The internal speed sensor is not working properly.” clears after Bosch's exact step, only the current condition has cleared; no failed part has been proved. If 514001 returns, the documented user branch is exhausted and the recurrence becomes the evidence for service.
