Thank you! I know we’re not crazy @Mantis_Toboggan - hopefully someone will look into it for us and help us to improve the experience. So far that is you and @Mark_Hulskamp that reported it on KICKR v5 and me on KICKR Bike v1. This definitely isn’t a “new” thing for me on KICKR Bike v1 and has been consistent through my entire experience of Zwift with KICKR BIKE Firmware v1.27.0 released on 5 April, 2022.
I have split suspicions of the “source” of this issue, but I cannot “point fingers” at Zwift or Wahoo because:
- It happens in Zwift AND MyWhoosh.
- It does NOT happen in indieVelo or Wahoo SYSTM.
I have had my bike since April 2021 starting on KICKR BIKE Firmware 1.16.0, and have updated through 1.22.0, 1.23.0 and 1.25.0 and unfortunately do not have more information about whether it changed during the time of one of these firmware versions. I do know it has been consistent with the combination of Zwift+KICKR BIKE Firmware 1.27.0 but cannot ascertain whether a change in ZwiftApp did this, or one of the Wahoo firmware versions did this.
I do see that for KICKR v5 there were a couple of ERG firmware changes - one on 11 March 2022 in v4.2.8 for “Power spikes while coasting when using ERG simulated speed mode” and one on the latest firmware on 14 February 2023 in v4.3.0 for “ERG Easy Ramp”. The updates for KICKR BIKE v1 do not have that much detail, with the latest being “Tweaks under the hood to improve your KICKR BIKE experience.” Absolutely useless and shameful on the part of Wahoo for that type of release note. At this point, I’m banking on the relationship between Zwift and Wahoo as hardware partners to determine the root cause and roadmap it for improvement.
I hope that this information can help someone at Zwift to investigate and triage on this issue for us. “Pretty please.”
