RPM not changing

My RPM on the Zwift app is not changing, if I am at 90w or 160w it is always stuck between 55-65… I can not figure out how to make it change, if I am doing something wrong or it is bugging…

(Btw sorry if I put this in the wrong category please lmk if I should change it…)

Please provide complete information about your Zwift setup, so that we might be able to provide some insight.

Okay, I have a saris water trainer


Along with a saris spd speed sensor

Here is what my setup looks like from the side profile

If I should move my saris speed sensor to another location on my bike please lmk…

I don’t see any sort of cadence sensor, so Zwift can’t possibly know your RPMs.

The Saris sensor can be used for either speed or cadence but not both. You are using it as a speed sensor. Buy a cadence sensor which you’ll install on the crank arm.

Alright thanks for letting me know do you have any suggestions for cadence sensors to buy?

Edit: I did a quick search…
Does this look good?

Without spaces between the beginning few characters

Also the reason that I thought I did not need one was because the cadence wasn’t just staying at 0 it was changing slightly for my speed…

The Coospo products are pretty popular and safe bargain choices. I use their HRM and ANT+ dongle with no issues.

The reason you see cadence even if it’s not present is because Zwift is trying to make the avatar’s feet move even if there’s no cadence sensor so the game is more accessible. Overall this is a good thing.
