A recall on this list does not mean your bike is affected: check the model and the production dates in the official notice. This list combines the EU Safety Gate, the European Commission rapid alert system, with the U.S. Consumer Product Safety Commission. A model can be sold under another name in another market, so always check the model and production dates in the official notice.

Still stuck? Take a photo of the display and show it to a local e-bike workshop. Bring the bike's system name (e.g. Bosch Performance Line CX) and the exact code; that saves diagnostic time and money.
