Cadence is not working properly

(Tony Bakke) #1

Too many posts about this crap cadence not working. Why isn’t this getting fixed. Renders Zwift unusable. I want my money back.

What are you using for cadence?

(Tony Bakke) #3

Wahoo cadence,wahoo speed,wahoo heart
Everything has been great for 2 months. Yesterday I was forced into a automatic update and it hasn’t worked since. (Zwift update)

Only the heart monitor stays consistent now. Cadence bounces from 171 to 0 and eventually drops out completely along with speed sensor

Bluetooth on laptop… sits on the handle bars., It’s been working great but now nothing.


Thanks for responding. Sorry for the rants

Have you tried changing the battery in the Wahoo S/C?
Do you see the same erratic reading swhen using the Wahoo app?

I have the same wahoo setup and have never had accurate cadence. Either is erratic like you’re experiencing or cadence drops when going up hill when my cadence is much higher - just not accurate and very frustrating.

This sounds like you may be experiencing Bluetooth dropouts, as Jeff had mentioned. Run through the steps in our Bluetooth interference article and if you are still having these sporadic readings, open a support conversation with us so we can take a look at your log files and get to the bottom of it.

The same problem here - Wahoo cadence sensor in Zwift shows wrong numbers (too low).

I honestly believe my sensor and its batteries are OK (both new) and NO BT dropouts, as I get correct numbers in Wahoo app and I can see the same (correct) values on my Garmin Edge (first is paired via BT, second via ANT+)

But while riding Zwift (either iPad Zwift companion app or Zwift for AppleTV4K) cadence info is NOT correct at all. Example - I see 85 rpm on my Garmin (which I guess is correct value) and in the same moment Zwift says my cadence is 50 or so … the difference changes - sometimes it’s bigger, sometimes those numbers are getting closer little bit … but basically, Zwift cadence values are nonsense.
