The gym I work at just purchased the Lifecyle GX bike. In the last few weeks most of the bike are out of calibration, so when level is all the way up (lowest resistance), the computer read level 1 to 8. I was able to re-calibrate a few but have 3 that failed calibration and say Manual Calibration is required. Today in class a crank arm came loose and just about fell off before the rider stopped.

Has anyone else had issues with the bikes or have knowledge on how to re-calibrate. We do have a maintenance agreement but they come every 3 months....
