To enjoy the full capabilities of the Hammer and Magnus trainer, including ongoing enhancements and Over-the-Air firmware updates, you must download the PowerTap Mobile App (Soon included in Rouvy App for iPhone and Android, too) from the Apple App Store.

Note: PowerTap Mobile is currently only available on iOS for iPhone 4s or later, iPod Touch 5th generation or later, or iPad Mini/iPad 3 or later.

To check for or perform over the air (OTA) firmware update, follow the steps below:

  • Bluetooth must be turned “on” on your iOS device (iPhone, Touch, iPad). Follow the onscreen directions below.
  • Log in with your PowerTap Mobile username (or use your Rouvy username), or choose Login Later and ride now.




  • Open the Menu and choose Update Firmware.

  • Select the trainer showing “Update Available” that you would like to update.


  • Select Update Firmware.

  • Sit back and wait for the magic to happen.

    ** Please note that the Hammer and Magnus have sleep timers, so be sure that your trainer has not fallen asleep by giving it a spin and ensuring its blue indicator light is blinking prior to starting the update.
