Make sure your Bluetooth is turned on your device. Press the Echelon button on the bike console. It should beep and the light will flash (if bike was connected to another device, this should disconnect it). 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.
