If cadence isn’t showing up, the the biking setting hasn’t kicked in yet. Have a look in the Wahoo fitness app find your TICKR X, go to Workout Profiles and select Biking.
Start pedalling and see if any cadence is showing up in the Wahoo fitness app on the Tickr X screen. From experience, you may may need to repeat the process a couple of times.
Once it’s working, it will stay like that until you change the battery. Just quit the Wahoo Fitness app and start using FulGaz. Cadence and heartrate will appear. Cadence can take a bit longer to show up because it needs to get a few revolutions going before it can give a good reading.
