Prior to contacting Zwift, be sure that your KICKR is functioning as expected with the Wahoo Fitness App for iOS or Android. For any challenges getting the KICKR working with the app, please open a ticket with Wahoo Support. If you’re still having issues with Zwift after getting the KICKR working with Wahoo’s app, try the steps below.
While the KICKR and KICKR Snap are designed to be plug-and-play trainers that just work, we’ve seen a few issues like the following:
- Your power/speed drops out
- The KICKR stops changing resistance
- The KICKR doesn't appear in the pairing screen
A first step to resolving all of these issues is updating your KICKR firmware. If these steps don’t address your issue, the answers to your questions may still be found in Wahoo’s Self-Help Guide or their support website.
KICKR Power Drop-Outs
For issues related to inaccurate power readings and resistance, first try doing a spindown. For additional power reading help, check out Wahoo’s Power Meter Accuracy Guide. If the KICKR is working well with the Wahoo Fitness app, the issue could still be related to your ANT+ signal. See our article on ANT+ signal strength for troubleshooting this. If you're using the Zwift Companion app to bridge a Bluetooth connection, see this article instead.
KICKR Stops Changing Resistance
If your KICKR stops changing resistance, your issue is likely one of the following:
- The KICKR switched from SIM into ERG mode. SIM mode allows Zwift to control the resistance based on the course gradient. If you are using other software that interacts with the KICKR at the same time, such as the Wahoo Fitness app or TrainerRoad, it's possible you may have unintentionally switched your KICKR to a different mode. Unpairing any other app should help solve this issue.
- Your trainer difficulty is turned off. In the Settings menu for Zwift, it's possible to turn off your trainer difficulty, making the trainer keep a flat, unchanging resistance. Modifying this setting may help.
- The KICKR isn't paired as a "Controllable" trainer. In the pairing menu, it's possible to unpair, or not pair, the KICKR as a Controllable trainer. It needs to be paired here in order to allow Zwift to change your KICKR's resistance.
KICKR doesn't appear under Pairing menu
If your KICKR doesn't show up on the pairing menu, it could be because:
- If you're trying to connect over ANT+, make sure you have an ANT+ dongle.
- Your ANT+ dongle isn't compatible with Zwift. See our ANT+ dongle KB article.
- If you're trying to connect over Bluetooth (BLE), see our BLE support article.
- The KICKR isn't plugged in.
- You're not searching under the Power or Smart Trainer section of the pairing screen. The KICKR will not appear when searching for a Speed/Classic Trainer.
