Hello. Using my Elemnt Bolt with heart rate sensor only, not having any other sensors or equipment.
How come that there are values for CADENCE in that section in the app even if I do not have a CADENCE sensor/equipment? What brings me to, what is the point of a CADENCE sensor if there isn’t one needed?
Thank you.
Which app are you asking about? If you are asking about SYSTM you can turn off the cadence metric. If you’re talking about the ELEMNT Companion App, then I think you can change your pages to remove cadence from your screen.
Can you give us a screen shot or pic of what you’re looking at? It would help us to help you.
Some models of the TICKR heart rate monitors report cadence based on movement. Not exactly sure how it figures it out, but this is documented somewhere…

I’ve got the TickrX and it is phenomenally accurate at cadence reporting. Freaks me out a bit!
Yep - it’s the one I have also. About 8-10 years old, and still TICKRing.
I have cadence sensors on all my setups, but remember seeing cadence kick in (TICKR in?) when the battery had died on a specific outing. I’ve never tried to determine its accuracy though.
Rob
It’s been a minute since I’ve used it too. Got myself a new rechargeable Trackr HR now but I do remember comparing the TickrX to other cadence sensors and found it remarkably accurate when compared to Kickr ‘18, Garmin Cadence sensor (ant+ only) and a Waboo cadence sensor as well as a couple of power meters (4iiii and Stages) It would take a couple pedal revolutions to kick in and would crap out at super high rpm’s (above 170)
Yeah, I remember that there was a 5-6 second lag before the TICKR’s cadence kicked in.
How do you like the new Trackr NR?
It’s great! Like that it’s rechargeable. Has really decent battery life and I really like that it’s accurate enough to measure HRV. Gave up my Polar H10 as a result.
P.S. @creaking_crank sorry for derailing your thread. Any follow up?
hm, sounds like there is more than one app. Was not aware of that. Confusing. The app I am referring to is showing itself as ELEMNT, its symbol has two upward pointing arrow heads, greenish/turquoise and gray.
Difficult to post a screenshot - the app is living on a mobile device, while using a computer for the Wahooo forum. no idea how to transfer.
ok, TICKR is the HR belt/sensor, understand. Thanks.
So just using Elemnt Bolt, original Wahoo heart rate belt/sensor (obviously the TICKR, which came with the Bolt bike computer) and the app. No separate devices or other equipment like sensor.
As far as I understand, to measure cadence a sensor is needed (crank arm/frame). Wahoo is writing about their RPM Cadence sensor on their webpages. But I do not have that sensor. That’s why I am wondering. 
No, do not want to remove the cadence section from the app.
Asking for an explanation for why I do see values for cadence in the ELEMNT app, even without having a sensor or other devices/equipment which could measure cadence.
As Glen and I were saying, some TICKR heart rate monitor models have a mechanism to measure cadence. That’s the reason you’re seeing cadence information on your ELEMNT even without a separate cadence device.
Rob
Wahoo could’ve explained and documented that far better.
Still interested in to know the base of that mechanism (automatism?) but it might be a company secret.
Anyway, thank you.
Help me understand something as I’m still a bit confused. Are you riding indoors? As in, are you riding on an indoor trainer (like a Kickr) using your Bolt to show you your heart rate info? If THAT is the case, then the cadence is being calculated by the trainer itself (it’s an approximation, based on the rotational speed of the trainer’s flywheel and the power being applied by the rider)
If you are not riding indoors, where are you seeing these cadence values? You say you see them on the ELEMNT app. Are you seeing these AFTER your ride is done, in the History section of the app? Or, are you seeing them reported on the BOLT while you are riding?
For a screen shot of the app on a mobile device (if it’s an iPhone, you generally click and hold one of the volume buttons then tap the power button to get that. once you have the picture, you can send it to your computer so you can share it on the forum. If it’s not an iPhone, google says:
appreciate explanation of indoor use. using mine outdoors only.
cadence values are part of usual workout data like map and HR values. just scroll down a bit, almost at the end cadence values are shown in a graph, similar graph like elevation/speed.
Can you provide a picture of your Tickr Heart Rate Monitor pod?
If not, does it look like any of these?
If so, it’s the Tickr X and it does actually (and accurately) report cadence.
If not, then I have no idea why you’d get cadence data unless somehow or other your mobile phone’s internal step counter is in someway being interpreted as a cadence sensor when you’re out riding.
Looks like the lower one, might be X v2 then. No mobile device involved when using, just Bolt and Tickr (HR belt).
Appreciate clearing that up, Glen. As an engineer, I still wonder how the (even accurate) reporting of cadence is possible, technically.
To me it’s all magic (as a non-engineer) 
Honestly, I’m really amazed at just how accurate TickrX was in capturing cycling cadence. I used the Gen 2 version and compared to an ant+ only garmin cadence sensor, the wahoo BTLE/ant+ cadence sensor, a crank based power meter that reports cadence, and a Kickr (which uses an calculation based on power output, speed of the flywheel, and other dark magic) and it tracks remarkably consistent with ALL of them. I don’t know if there’s a built in accelerometer in the TickrX that somehow track the slight upper body movement changes or what they did but it’s a pretty cool feature that they have not resurrected in their current HRM.
