How to Update Wahoo Smart Trainer Firmware (iOS)

This page describes how to update firmware from an iOS device. For Android devices, see How to Update Wahoo Smart Trainer Firmware (Android).
Note: the Wahoo Smart Trainer firmware can only be updated from iOS and Android devices. 


Wahoo updates your KICKR's firmware (a kind of software) frequently to deliver the best indoor training experience possible. Ensuring you have the latest firmware resolves many issues, keeping you cranking and on the podium.



  • Bluetooth® enabled iOS device on iOS 10.0 or newer
  • Your iOS device actively connected to the internet over WiFi
  • The Wahoo app for iOS
  • A KICKR that is not connected to any additional apps or devices (ensure previously connected devices are off/disabled and no other apps are running in the background)


Update Steps:

Ensure Bluetooth is enabled in your iOS settings and that your device is within 5 feet of the KICKR, then follow these steps to pair your KICKR:

  1. Open the Wahoo Fitness app and check that your KICKR is plugged in and powered on

  2. Select Sensors in the bottom left corner

  3. Select Add New Sensor

  4. Choose your KICKR from the list of available sensors

  5. Once certain you are connected to the correct sensor, select Save Sensor, choose the workout profiles you would like your KICKR to be active for (ex. Indoor Cycling), then tap Done in the upper left corner.

  6. Upon establishing a connection with your KICKR, the Wahoo Fitness app will determine if your KICKR's firmware is out of date. If an update is required, the app will display an option to Update Now.
  7. Click "Update Now" and leave your device near the KICKR until the update is complete.

  8. Once the update is finished, we recommend toggling Bluetooth® off and back on to refresh the connection, as well as restarting your trainer.

Your Wahoo smart trainer is now updated to the latest firmware and ready to ride!


If issues updating persist, please take a look at our signal interference article to eliminate possible conflicts with other devices and try again.
