Make sure your Bluetooth is turned on. Press the Echelon button on the bike console. It should beep and the light will flash. Open the app on your device. If you tap "more" at the bottom right, then "select equipment", then choose connect bike, a screen will ask you to connect. Tap and a device list will appear. Tap the "ECH" device (should be the only one listed) and your bike will beep and the light around the button will stop flashing indicating your bike is connected.

If you continue having issues connecting to the bike, unplug the bike, wait 10 minutes and plug back in. If this does not work, please contact customer service.
