Peloton Heart Rate Monitor Not Working (Plus easy fix)

One of my biggest problems when we got our peloton bike a couple of years ago and our tread this past summer has been the heart rate monitor. Today I want to highlight some of the common reasons why your peloton heart rate monitor may not work, and, most importantly, things you can do to fix that issue.

As a whole, some of the reasons why your peloton heart rate monitor does not work include low battery, loose chest strap, or dry sensors touching the skin. Also, if your peloton HRM keeps flashing blue make sure your bike has Bluetooth switched ON.

NOTE: I won’t be covering here my overall review of what I think about this device. I’ve already covered that in the “peloton heart rate monitor” article, which I recommend you read.

Peloton Heart Rate Monitor Not Working

I’ve spent the last couple of months troubleshooting my peloton heart rate monitor before I’ve replaced it for the whoop strap. As a result, I’ve spent dozens of hours searching through the web about all the possible problems there are with this device.

Why does my peloton heart rate monitor not work? As a whole, the peloton heart rate monitor is not working correctly because of the conductivity issues between the electrodes and the skin, incorrect electrode placement, or static electricity caused by wearing synthetic shirts.

What is conductivity? In short, high conductivity refers to how easily an electric current can flow through the skin. Moist skin has a higher conductivity and can easily pass an electrical current, which makes the heart rate monitor readings more consistent.

On the other hand, the dry skin has low conductivity, which can cause the peloton heart rate monitor to stop working, as well as provide an inaccurate reading.

Please remember that the peloton chest strap heart rate monitor picks up the electrical signal (which works similarly to the electrocardiogram).

Here’s how it works.

Every time the heart pumps, the heartbeat is caused by electrical activity. The peloton HRM can pick this electrical activity and transmit it into the monitor.

See below.

As you can see, the sensors in the peloton heart rate monitor do not rely on the heartbeat itself. Instead, it works by measuring the electrical activity that causes the heartbeat.

To enhance the accuracy of heart rate monitor sensors and ensure they pick up the strongest signal, the peloton chest strap (just like the ECG) has to have high conductivity (more on that next).

On the other hand, if your heart rate monitor does not conduct the signal efficiently, it can stay not connected or drop the heart rate readings randomly in a class.

How Do You Get The Peloton HRM To Work?

As a whole, you can make your peloton heart rate monitor work by fitting the strap snugly close to the skin (just under the chest for males and under the sports bra for females), as well as properly moistening the electrodes to enable high conductivity of the electrical impulse.

Here are the things you can do to improve peloton heart rate monitor connectivity.

  • Wet HRM electrodes – Sweating is enough to conduct the signal accurately because the salt in the sweat helps to conduct the electrical signals. However, in the beginning, before you start to sweat, you can pour the water on the peloton heart rate monitor electrodes.

The only problem I find is that if I do an easy ride that doesn’t make me break a sweat, my heart rate monitor can stop working mid-workout.

  • Use conducting gel – I find that using conducting gel or ultrasound gel is better than water because it lasts for the whole class. Conducting ECG gel reduces the resistance between skin and electrodes, which enhances the accuracy of the heart rate monitor.
  • Use saliva – If you don’t have a conducting gel, you can always use the saliva. Saliva, as well as other saline solutions, are a mix of water and salt.
  • Tighten the elastic strap – To ensure your peloton heart rate monitor works, adjust the strap to fit closely to your skin under your chest. If the strap doesn’t contact the skin, is placed in the wrong place, or is too loose, the signal can get impaired.
  • Use different clothes – Using tumble dryers can increase the electrostatic charge. Also, as well as wearing synthetic clothes that rub against each other and generate static electricity. This can create a disturbance that impedes the signals.
  • Wash the strap – Regular cycling and sweating lead to an increased amount of chloride on the heart rate monitor, which can cause corrosion. To maximize the life span of your peloton heart rate monitor, you should wash the strap regularly in lukewarm water and hang it to dry.

Peloton Heart Rate Monitor Not Showing Up

Now let’s talk about what happens if the peloton heart rate monitor is conducting properly, but the signal is not showing up on the peloton bike.

Why does my peloton heart rate monitor not show up? As a general rule, the peloton heart rate monitor is not showing up because you’re trying to pair multiple devices at once, a battery of the heart rate sensor is running low, or your Bluetooth function is disabled in the peloton bike settings.

I use my peloton bike together with my friends and we use multiple different heart rate monitors. Every time they hop on the bike, they like to connect either Fitbit or other HRM, where I was using the original peloton HRM.

This means I had to manually change the setting after her rides and ensure the bike is actually pairing with my heart rate monitor, not with hers.

How Do I Get My Peloton Heart Rate Monitor To Show Up

  • Unpair all other devices – If you had connected the peloton with other Bluetooth devices, the bike may set onto another person’s signal, not yours. Also, ensure you’re using the peloton heart rate monitor for the bike and not for other devices at the time.
  • Avoid electromagnetic disturbances – If your bike is located close to the cellular phones, electric security gates, or even a TV that is on, it may cause false readings and provide incorrect data. You can avoid it by placing the bike away from any equipment that has electronic components.
  • Change the battery – If the peloton heart rate battery is running low it will reduce the transmission range. Changing the battery will ensure you have a strong signal and can pair with the bike.

Also, replacing the battery can help you if you notice that your heart rate monitor does not flash.

Peloton Heart Rate Monitor Not Working After Battery Replacement

If your peloton heart rate monitor does not work after replacing the battery you can try to reset the Bluetooth, switch WiFi networks, and turn the bike on and off. Alternatively, you can contact the peloton customer service support team and explain your issue.

I called peloton support about my peloton heart rate monitor issues (plus gave them all the details of what I did before that) and they advised me to clear the cache on the touchscreen.

Here’s how to clear the cache on the peloton.

  • Power off your touchscreen – You can turn off the touchscreen by pressing the power button on the top. After a couple of seconds press the “shutdown” option.
  • Hold the “volume up” button and “power” button together – This will reboot the system into recovery mode.
  • Wipe cache partition – You can select the “Wipe Cache Partition” option by using the volume buttons.
  • Reboot system now – After the partition has been completed, press on the “reboot system now” icon.

If this doesn’t work, the last hope is to ask for a replacement or simply choose a different heart rate monitor.

Peloton Heart Rate Monitor Not Showing Zones

Another common issue with the heart rate monitor on the peloton is that you can wear the chest strap and display your heart rate, but the peloton bike doesn’t display the heart rate zone you’re currently at.

Why peloton heart rate monitor not showing zones? In short, this happens because of a glitch in the software that stores your personal data. The peloton HRM relies on the information that you put into the software (age and HRmax), and it uses these numbers to calculate and display the power zones you training at.

Peloton heart rate zones are based on your HRmax (which you can leave as default or you can input manually in the settings). Plus, the HRmax is calculated from your age.

This means if the peloton bike had a software update or you’ve experienced the loss of electrical power (e.g. power outage), it could make your profile information disappear.

How to get peloton heart rate monitor to show zones

  • Check your profile – The easiest way to fix this issue is to updated all your information in the settings. After you re enter your personal data you should start to see the heart rate zones again.

Peloton Heart Rate Monitor Not Showing Correct Heart Rate

One of the problems you may encounter is that the heart rate monitor does work, but it provides you with incorrect, inconsistent, or abnormal heart rate metrics while working out.

Why peloton HRM does not show the correct heart rate? As a whole, the peloton heart rate monitor is not showing the correct heart rate because the strap doesn’t fit snugly into the skin, you have electromagnetic disturbances, or the battery of the heart rate sensor is running low. It also can be the wear and tear of the peloton HRM.

Having the chest strap too loose, placed in the wrong place, or not conducting enough signal to the receiver can cause abnormal readings.


As you can see, problems with peloton heart rate monitors are common. Usually, they’re flaking out and dropping out a lot during workouts. For most cases, these issues are related to poor conductivity, battery life, or just regular wear and tear.
