Hi,

Ok, that's from the ID a crossergometer because of the X at the end.

Have you ever had the Ergo without power for a long time?
Otherwise you can try vl. then reload the data from the brake.

Otherwise, if the wrong brake is really installed, I don't know what to do.
I don't have a suitable one.

Maybe ask there:

On the page you can see one for Coach S, but that doesn't help either.

You need one that provides SK10S as an ID.
Only the S has 600W. One with B would be an ergometer, but only 400W.

Wolfgang. Could you please clarify to try "vl." from the brake? Brakes have not been changed but yes the bike was off for a while.

Hi,
