Bosch eBike 144001: Your control unit cannot be charged.
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
Your control unit cannot be charged. The charging voltage at the USB port on the control unit is too high. This means that charging is not possible. For 144001, Bosch's user step is: Please use a different power bank or a different charger to charge the control unit via the USB port. If the same code returns, preserve the display and stop repeating resets.
Safety first
Stop and check this first
- Do not open the battery, drive unit, display, remote or charger and do not probe contacts. Stop for moisture, damaged cables, sparks, swelling, burning smell or repeated shutdown.
Safe checks you can perform

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.

Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Evidence: Bosch eBike Systems — official fault code 144001
- What the official step decidesPossible
If “Your control unit cannot be charged.” clears after Bosch's exact step, only the current condition has cleared; no failed part has been proved. If 144001 returns, the documented user branch is exhausted and the recurrence becomes the evidence for service.
