Continuing Problems with Zwift Losing Control of Wahoo KICKR - DANGEROUS!!!


(Kerry Webb) #1

I was sprinting fast down the long steep hill toward the finish line, when suddenly my KICKR dropped out of Sim mode into Resistance (or Level) mode. I nearly pulled a muscle due to the extremely abrupt change in resistance level. I’m afraid this is going from a nuisance issue to a problem putting riders at risk.

Zwift - Can we please get some feedback on this problem please?

Hi Kerry,

We’re aware of the issue and are trying to figure out why, exactly it seems to be happening. It seems to manifest itself in a different way each time we feel we’ve solved it. :frowning:

Thanks Eric. Let me know if there’s any information about my riding environment I can provide or particular data to collect on future rides.

Eric - Will my log be of any assistance?

Here’s an excerpt from the log showing what I felt in terms of resistance (near instantaneous jump from 144.90 watts to 811.32 watts. This was proceeded by 18 seconds of KICKR transmission failures.

Has zwift looked at the kickr firmware? I updated to one of their beta firmwares 1.3.8 and it helped with dropouts with other apps (veloreality & bkool), so I hope it helps with Zwift
