Frequently asked questions
What can the report contain?
Depending on the bike, it includes component and software details, mileage, service reminder and battery readings. Only confirmed values are shown; missing information is not estimated.
Can it help when buying a used eBike?
Available readings help you assess recorded mileage and battery information. They do not replace a test ride, mechanical inspection or battery capacity measurement.
Does an absent fault code prove the bike is fault-free?
No. The report states when fault evaluation is unconfirmed. This does not establish a fault-free condition.
Is the report free?
Yes. The download and offered email delivery are free. Reviewing BlauWerk is optional and is not a requirement.
