According to the Kommoda bike computer manual, error code 06 means "Under voltage protection"

If your Cyrusher bike drops dramatically from 50% battery life to no power and there's an error code 06, then a failed battery or bike computer could have caused this issue, so we need to test the battery's voltage:

1.  Test the battery's voltage when it's fully charged
2. Test the battery's voltage when it's dead/drop out

_Please see this article for how to test the battery's voltage:_

If you tested the fully charged battery is 50V, and the dead battery is 50V, then you might have a failed battery.
On the other hand, if you tested the fully charged battery is 50V, and the dead battery is 40V, then the bike computer is having incorrect issue.
