I’ve been using Trainer Road with My Wahoo Kickr Core for the past 18 months or so without an issue. I do spin downs and calibrations in TR every few workouts, and they always work as anticipated.
Today, however, when I did a spin down, the display never showed a speed. It’s hard to know if I’ve spun it up to 21.7 mph when the software doesn’t show a speed.
I did connect with the Wahoo software, and it shows a speed, so I know the trainer is sending a value for speed.
FWIW, my TR workouts typically average between 25-28 mph in the gear I usually use. The last few workouts have averaged 16-18 mph. While I recognize that trainer miles and speed aren’t the same as road miles and speed, it did seem odd that they would suddenly drop 10 mph.
Power still feels accurate, and I’m using the same cadence and gears I normally would.
I had the same issue about 3 days ago on a Core when calibrating before a ramp test. I uninstalled TR app and reinstalled and everything worked fine. I haven’t raised a support ticket so not sure what was going on.
When I tried calibrating my Core in the TR app after the most recent Kickr Core software update, I kept losing speed attempting to get it up to 24 mph for calibration. Then I realized during calibration the TR app was in ERG mode and didn’t switch to RESISTANCE. This was likely because I was already 10 minutes into a workout when I was trying to calibrate the Core. This appears to be a new bug either from the Wahoo software update or in the TR app. In any case, I manually switched it to RESISTANCE and was able to calibrate the Core.
I had an issue a while ago where the Kickr was showing an incorrect temperature (something like -200F) and never completing the spin down. Wahoo Support had me do a Factory Spin Down and that fixed the issue.
While it shows 0 speed, it actually calibrates just fine. Put it 53x11 and spin out hard, so you will hit like 50 km/h. Let it go and you will see the success notification on TR screen. I believe it’s a Kickr bug, I saw the same problem with Wahoo app some time ago.
FWIW, Kickr support stepped up and helped me resolve the issue. The last update apparently corrupted the driver, but a full reinstall and factory recalibration fixed the issue.
Thank you for the follow up. When using the PC via ant+, make sure that the bluetooth is toggled OFF on the PC and the iPhone. Alternatively, when using the iPhone, turn the bluetooth off on the PC and unplug the ant dongle.
For the sake of the troubleshooting, let’s keep the headphones off. Also, if you are streaming movies or music, please keep those off.
We will do the troubleshooting on your iPhone.
First, let’s reset the bluetooth of the device to establish a secure connection:
Un-pair your KICKR from all apps you’ve connected to.
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, plug back in)
Turn on your phone
Turn on Bluetooth
Open the Wahoo Fitness app
Go to the Sensors page
Choose the option to add your KICKR
Make sure the KICKR is awake
Choose the KICKR and save it
Once you have connected and save the KICKR, please update the KICKR to the latest firmware version (as downgrading can create issues for anything we’ve fixed in the updated firmware) and then use the steps below to perform a factory spindown and calibrate the unit”:
-Open the iOS Wahoo Fitness App and navigate to the Sensors section
-Connect to KICKR from the sensors screen and save, selecting your preferred profiles
-Go to the WORKOUT page to select a KICKR-enabled profile and start a workout
-Tap the ((*)) sensor icon in the upper left once.
-Once the drop down menu appears, tap on the wrench & hammer icon next to the KICKR
-Tap the instructions paragraph (above “Perform Spindown”) five times - The factory spindown instructions will then appear below
-Tap Perform Factory Spindown (may require scrolling down on smaller screens) and follow
After doing the factory spindown, you may need to power cycle the Kickr and your iPhone (unplug/restart).
After you have completed the factory spindown, please let me know the results.
