Hello,
I bought Van Rysel D100 smart trainer from Decathlon with Zwift Cog and Click. It’s basic very smart trainer with no cadence.
Decathlon says on it website that cadence sensor is not there and you should buy external sensor.
When I connect smart trainer with OneLap app, which is supposed to be app for firmware uprgrading, calibration etc. It shows my Watts, speed and it shows 0 cadence.
Then when I connect smart trainer with Zwift, it also connects Cadence. Why? How? It shows almost completly random RPMs drugin workouts. How does Zwift calculates that? During workouts it non stop telling me to pedal more, it shows like 20-30 RPMs even when you are spriting and putting extra Watts effort.
Since I am new in Zwift I didn’t know I can unconnect that. Now everytime I login I connect my smart trainer and then I need to think about unpairing cadence.
Why Zwift doing that?
Thanks

The thing that is weird is the trainer. It announces that it offers cadence but doesn’t send any data. Zwift does not assume that everyone has cadence data and invents a value when it doesn’t get one so that the avatar’s legs move. The cadence targets in workouts will be confounded by this. I recommend getting a cadence sensor. It’s cheap. Here’s an example:

Hi @Martin_Martinec,
Welcome to the Zwift forums! Jose from Zwift Support here.
You’ve hit on a known topic with the Van Rysel D100 smart trainer. As you noted, it doesn’t have a built-in cadence sensor. The cadence you’re seeing in Zwift is an estimation based on power data, which often leads to those random or inaccurate readings, especially during sprints.
This is a common limitation with the D100 model, as Paul mentioned, many members find the best solution is to unpair the trainer’s estimated cadence and use a separate, dedicated cadence sensor for accurate data.
For reliable cadence on your Van Rysel D100 and to avoid workout confusion, we highly recommend getting an external cadence sensor to pair with Zwift alongside your trainer.
