Bosch eBike 152001: The temperature of your control unit is too high.
Risk level
High
Professional inspection is recommended.
Urgency
Immediate
Quick answer
The temperature of your control unit is too high. This may mean that no motor support is available to you, and your eBike switches off. For 152001, Bosch's user step is: Let your eBike cool down for 15 minutes in a cooler environment. Avoid direct sunlight here. 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.
Safety first
Stop and check this first
- Stop riding or charging while a battery, drive unit, cable or connector is abnormally hot. Keep it away from combustible material; smoke, swelling, hissing or burning smell requires emergency help.
Safe checks you can perform
