Watts supersonic

Hi, I don’t know what to do but I looked It Up in Google and can’t find the solution! The last times I was on Zwift my screen said I was riding with supersonic Watts out of a human being!! I’m not a profi, 61, woman and recreative biker! Zwift put me in the B category and I don’t deserve this and it’s not for me! coming from “D Cat” and
should be normal. What can be the solution? Buying another equipment? i have the Bkool equipment.
Thanks. Karen


If it’s a one off event that was a blip in your trainer that caused your power to spike you can email zwiftpower@zwift.com and ask them to error/delete the problem events.

If you trainer is permanently reading high it might be a case of riding inaccurate trainer? Do you know the model name/number?

Hello, FIRST of all thank you so much for your answer.
It’s not always these peaks of Watts. Today I’ve done 20km sprint and saw one short moment that my Watts went in red. Have done the sprint in 18min!!! Am I so good??? :smiley:
I am not a prof but make fun and sport! Don’t like to be in B cat.

Thanks x your help. Really I appreciate It. Regards

If you search the forum for “zycle” you will find some previous discussions about the bike. Summary: it’s not accurate and can’t be calibrated.

Thanks Paul. I’m currently in the A Cat. Imposible. It’s true that the ZYCLE SMART trainer can’t be calibrated. I know that.
Regards and thanks again.

Hi, thanks for your answer. Yes, I’ve been in contact with the zwift support team. :+1:
Yesterday I’ve done some races and had the same problems. I am a superwoman with high Watts!!! A pop Up screen informed me that It was not normal. I am a “A Rider”!!!
Even my races ( Tiny races) from yesterday don’t appear in zwiftpower ! i finished them and they are in my activities and Strava.
I think my ZYCLE smart have a tecnical problem! I want to be sure before I invest in a new one.
Thanks for your answer.


If you want a good smart bike, the list is very short: Tacx Neo Bike, Wahoo Kickr Bike, Wahoo Kickr SHIFT, Wattbike Atom. The StagesBike SB20 is also fine but the company is bankrupt and should be avoided. There are no other good options unless you want to put a bicycle on a direct drive smart trainer, or buy a set of power meter pedals to use on your existing bike.

i am looking for the Wahoo kickr. For me it’s a invest of money but…zwifting a lot! i want a medium/good one. The Tackx came also in my mind! Never again the ZYCLE( spanish brand). Thanks mate for the advice of trainers. It came on the good moment. Regards.

Hi @karen_OWL_60_de_beul , thanks for sharing your thoughts with us. This is Juan from Zwift.

Contributing to the excellent suggestions, I would like to share this article with you to learn more about compatible direct drive trainers.

If there is anything else we can help you with, please let us know. You are always more than welcome.

Gracias Juan. Thinking for a Wahoo Kickr. But hesitating for warranty options. I’ve ZYCLE( Spanish brand) and not very Happy about It.
Anyway, thanks for your help.


Keep an eye out for Kickr Bikes, you might find some V1 Kickr Bikes available refurbished. They are really good units. Easy to adjust, just work well.

By the way, the [OWL] in your name causes the forum quotes system to go crazy. :wink: Normal parentheses work better.
