Hi @Trond-Magne_Hansen! Welcome to the forums! I’m Francisco from Zwift Support.
Appreciate you sticking around! I’m ready to throw out some tips.
With the Wahoo KICKR Bike Shift in Zwift, ERG mode allows you to focus on maintaining your cadence while the trainer automatically adjusts resistance to keep you at the target power.
If ERG mode isn’t working as expected, here are a few steps to try:
- Update Firmware and Software: Ensure that your Wahoo Kickr Bike firmware is up to date. Currently, our records show that you have firmware version v1.21.18. The latest version, according to Wahoo’s release notes, is v2.2.22. Please also verify that you are running the latest version of Zwift on your device. Today, a new game version was released; you can find more information in this thread.
- Check Connections: Confirm that your trainer is properly paired with Zwift.
- Verify ERG Mode Settings: In Zwift, make sure that ERG mode is enabled during your workout. You can also check the Wahoo app to ensure that ERG mode is functioning correctly.
For additional insights, I’d recommend checking out this Wahoo forum thread and this Zwift forum discussion here, which might provide helpful tips from other users who’ve experienced similar issues.
