Wild cadence readings

[Gareth_Lock (Gareth)]

Hi,
I’m relatively new to Zwift so I don’t have a good understanding of the tech stuff yet.
I’m using a Tacx Bushido & it was going well on my road bike, but I’ve recently put my old MTB on it, as I can pretty much leave it as a permanent set up.

During some workouts which cadence changes, my on screen cadence regularly fluctuates while my actual cadence hasn’t changed, which makes these workouts a bit of guess work.

I’m wondering if adding a Bluetooth enabled cadence sensor will help to get more accurate & reliable readings?
I’m running my Zwift through an iPad & android companion app.

Any recomendations?
Wahoo BlueSC?
JetBlack JBT-102?

Mine is the same. The workouts arent really workouts now. Just oeriods where i fight to try to figure out how my cadence is going from 79 to 122 in a few seconds and how i cannot follow the on-screen instructions.

I have a brand new 2 wk old wahoo kickr core 6 & its never worked right. Neither Wahoo nor Zwift seem keen or knowledgeable on how to help

Zwift can’t fix your trainer. Please read my answer over here:

Why! cadence jumped

Wahoo trainers don’t measure crank arm revolutions, they estimate cadence but that doesn’t work for everyone so installing a cadence sensor is sometimes necessary. Here’s a previous discussion about it:
