Hello everyone,
I am also the (not so) proud owner of a Schwinn IC4 bike. I found myself with inflated numbers like the rest of you. Have a look here at a previous post that details my problem and my results after the calibration process I followed that was posted in this thread.
In short, it takes more effort to produce the same numbers I was getting before. If anyone has comparisons between a properly calibrated Schwinn and a trusted power meter I’d love to see them.
