Hiya.
First post here, so don’t shoot me.
Been using my Kickr V6 without issues since I got it end of January.
Recent couple of rides however have not been happy, as the Kickr’s resistance has not been changing. I get the same resistance going up and down hills or on the flat.
Not changed anything in either the Wahoo app or Zwift.
I am not running in ERG mode.
Firmware version is 5.0.14.
Anyone else seeing this issue?
Cheers
Simon.
Looks as you might not be alone, maybe @shooj can shed some light
On the pairing screen does the Kickr show up under Resistance? Is the Trainer Difficulty setting appearing in the Settings menu, and set to something other than zero?
Power Source and Resistance are set as the Kickr. I have a Wahoo Cadence Sensor, so use that, and a heart rate monitor.
All pair up as normal.
In the Zwift settings menu I did see the trainer resistance setting set in the middle. Between off and max. I have not ever changed that.
Sounds like you did everything right. I would make sure the trainer firmware is up to date, and try using it with another cycling app to see if it works differently.
Morning folks.
Will try the other app at some point as I already have the MyWhoosh loaded on the phone.
While posting the OP to you guys, I did open up a ticket with Wahoo Fitness Support.
I got a long/comprehensive (albeit copy/paste), response with the direction to unpair/delete all instances of the KIckr bluetooth and its app on my devices, remove the Wahoo app, reset the KIckr, then do the opposite to reinstall/re-pair. etc, etc.
So nothing un-expected.
I was then instructed to do the Spindown test.
Question though:
For the Spindown, the support guy instructs an ERG test gradually going from 100W to a mighty 300W (“If possible” - I am 60 so this may be a challenge - but I’m up for it), then back down to 100W.
All in the lowest gear - really?? The lowest gear?
So cycling up Mon-Ventoux (in 34/32T for me) at 300W max by the sound of things? (OK, just for a minute)
…and this should be done “on first use and every 2 weeks after” apparently.
Is this what everyone does with their Kickr?
I very much doubt it, but welcome your feedback.
Best of luck with them, be warned they can be hit and miss, sometimes you have to chase them, I’ve had a ticket inn for about 2 months now, to solve a problem with elemnt app crashing if synced with Komoot
I had to do this last month and had my V5 replaced under warranty,… Using ERG mode its actually fairly easy to do and I found Wahoo support to be great. Not sure why they want you to do 300w, maybe its the test range for the V6. These were my instructions
Once the above is completed, please perform a 5min workout using Wahoo Fitness app selecting Erg Mode and save it. I will be able to check both the automatic spindown results and the workout logs.
Test:
Thanks for the info mate. Yes, they also added 3 extra steps to mine, in addition to what you put. After 200 watts, I had to do 250 watts, then 300 watts, back to 250 watts, then the rest of what you put.
300 watts nearly killed me lol, so I did the test without it.
@Jason_J_SPM , if you finished the test ok, can I ask what led to your return under warranty, bearing in mind I assume you finished the test ok?
Thanks.
Resistance issue was my complaint, the tech wanted that info from the test before proceeding further. As soon as they saw it I got an email stating it would be replaced.
Hi guys had this same issue on my Jetblack volt v2. Resistance was fine when paired to Jetblack app. What I did just now was just mess around with the trainer difficulty by one step and it seems to have at least helped - resistance does change now, but I’m not sure I’m quite yet back to where it was… will run 100% now to see what’s what (usually run less because Frankenbike - Jetblack please give me virtual gears 
)
Edit: yup, 100% certainly did something, very noticeable now… will go find a hill next.
Edit 2: yupyup. Everything back to normal by just fiddling around. Can set it back to where it used to be and everything is fine.
An update folks.
Looks like the complete reset and removal/reinstall of apps and Bluetooth configs have sorted my Kickr v6 - at least for now. The customer services directed tests showed my Kickr was changing resistance again OK.
Retesting in Zwift - showed the resistance was also fine again.
To be honest I was kinda impressed with the speed of response from the Wahoo customer service team. I got responses and advice within 24 hrs each time, and that including their analysis of my test data from the Wahoo app.
So all good for me - at least for now.
If it continues to work OK - then great, but if it keeps re-occurring I will be looking at raising another ticket with them, and maybe a replacement.
Anyway - thanks for the advice. 
Good to hear
Hi Simon
I’m having similar issues. I had a Kickr Core and I’ve recently got the v6. For the same efforts my watts are significantly lower on the V6. Would you mind copying and pasting the exact instructions you received about removing and resetting everything?
Thanks!
Hi Roger.
Sorry to hear you having issues.
Here is the response I got - and its quite lengthy. The second bit is what I got after they analysed the file I send back to them.
Have to say after the initial reset at the beginning the ERG mode test went OK for me. Having said that the 300 Watt part of it nearly killed me as I’m 60 years old lol.
Note: there are a couple of links in there which I have had to break up with spaces as this forum won’t let me post them complete.
Good luck
Simon
Hi Simon,
Thank you for contacting Wahoo Fitness and we’re sorry you have experienced an issue with your KICKR.
Please follow these troubleshooting steps for me in this order:
- Un-pair your KICKR from ALL apps and devices to which you’ve connected.
- Forget the KICKR if it is listed under your Bluetooth settings
- Toggle Bluetooth off. Please note, this needs to be done from within the Bluetooth menu of the Settings app. Doing this in the Control Center does not fully turn off BT.
- Delete your Wahoo App
- Turn your phone off
- Download the app ensuring this is running the latest firmware update
- Reset your KICKR (unplug for 30 seconds)
- Turn both the Kickr and your phone on
- Access Wahoo App
- Select “Sensors” in the top right corner (icon with two waves), then the plus (+) to add a new sensor
- Choose your KICKR from the list of available sensors
- You’ll need to perform a spindown to calibrate your KICKR (as outlined in the section below) on first use and every 2 weeks after. It’s important to update your KICKR as well by following [these instructions](https: //support .wahoofitness .com/hc/en-us/articles/204281674-How-do-I-update-the-firmware-on-my-Wahoo-Smart-Trainer-Android-).
- Select “Save device” and choose the workout profiles you would like the KICKR active for (ex. Indoor Cycling)
- Select “Ok” to complete the pairing and workout selection process
In conclusion, I would like to have you run a quick test using the Wahoo Fitness app so that we can see how the hardware on the trainer is performing. The purpose of this ERG mode test this to isolate the trainer from any potential software issues and allow us to review the trainer control within our ecosystem.
In the results we look for a smooth power profile that shows gradual increases and decreases in power, as changes are made in the Wahoo app. As power changes, we analyze the cadence data to see if the trainer is adjusting the resistance to compensate. Since this test is for diagnostic purposes, it is important that you complete the test as instructed, regardless of the data you are seeing.
Please test using the Wahoo Fitness app on iOS or Android with all additional apps and devices capable of connecting to the KICKR turned off/ closed out. To access this please begin an “Indoor Cycling” workout with the Kickr paired and then swipe the screen until you see the KICKR control screen pictured below. Tap on the ERG tab at the top and follow the instructions below.
- Pair your KICKR to the Wahoo Fitness app
- Begin a workout in ERG mode and leave the bike in your lowest gear
- Start spinning, set the power target to 100 watts and hold steady cadence in the 70-100 rpm range for one minute
- Set target to 150 watts and hold steady cadence for one minute
- Set target to 200 watts and hold steady cadence for one minute
- Set target to 250 watts and hold steady cadence for one minute
- Set target to 300 watts (if possible) and hold steady cadence for one minute
- Set target to 250 watts and hold steady cadence for one minute
- Set target to 200 watts and hold steady cadence for one minute
- Set target to 150 watts and hold steady cadence for one minute
- Set target to 100 watts and hold steady cadence for one minute
Additionally please to send me:
- A copy of your receipt / screenshot proof of purchase
- Confirm your current shipping address:
I look forward to hearing from you.
Many thanks,

After they analysed the file I sent this is the response. By now the Kickr V6 was working OK anyway.
Hi Simon,
Thanks for you response and sending the Erg test file over.
I forwarded your Fit. File to our software team who analysed it and confirmed that based on the test result there is no hardware issue with how the unit is performing when set up with the Wahoo Fitness app. Indeed, below you can see your test result which respects the expected standard. If there had been an hardware issue with your trainer, the power data (in pink) would have been spiky or has not changed at all. However, here you can notice that it is completely smooth and consistent, even when power was increased.
As a result the issue is likely related to interference or the connection between the KICKR and the device you are running Zwift on.
With the above in mind, please complete ALL of these steps in this order:
- Un-pair your KICKR from ALL apps and devices to which you’ve connected. This includes but is not limited to phones, tablets, smart TVs, cycling computers, fitness tracking watches, the Wahoo app, Zwift, Training Peaks, etc. Please also ensure that all devices or powered down or have their BT disabled, except for the device on which you are running the Wahoo app.
- Forget the KICKR if it is listed under your Bluetooth settings
- Toggle Bluetooth off. Please note, this needs to be done from within the Bluetooth menu of the Settings app. Doing this in the Control Center does not fully turn off BT.* Turn off your phone
- Reset your KICKR (unplug for 30 seconds)* At this point, turn the device you are using Zwift with on
- Pair the Kickr directly from the Zwift App.
Zwift also recommend connecting to the KICKR via ANT+ FEC connection type; this requires fitting an ANT+ dongle but is the strongest and most reliable connection type.
If the problem persists, are you able to make a test and use Zwift from your phone ensuring that Wahoo Fitness app is not running in the background?
Many Thanks,
