How to Choose Good Heart Rate Monitors for Cycling

Type of Heart Rate Monitor

One of the first things to think about is the type of heart rate monitor to buy. It impacts the design or how you should be wearing the heart rate monitor. Consider what you are most comfortable with. More importantly, think about what can yield the highest level of accuracy.

Optical Heart Rate Monitor

This is a popular heart rate monitor from some of the big names in the global market, including Fitbit and Apple. It uses an optical sensor, which is incorporated into a smartwatch. It rests on your wrist instead of your heart. It uses light transmitted on your skin and analyzes this light as it comes back. It counts your pulse, which is what is displayed as your heart rate. These monitors need to be fit as snugly as possible for more precise heart rate readings.

Chest Strap Heart Rate Monitor

If you are looking for better accuracy, however, then this is what we can recommend. It is strapped on your chest and it detects the small electrical signals that your body makes when you are cycling. It is not as convenient as an optical heart rate monitor since you need to wear it around your chest, which some people might find to be too restrictive.


Regardless of the type of heart rate monitor that you use, comfort is a priority. Otherwise, this will affect your performance as you pedal.

They have app functionality, which means that they can be connected and controlled through a smartphone. You can even connect it to a computer and use compatible software. This will help you unlock the full potential of the cycling heart rate monitor that you are using.

Battery Life

Almost all heart rate monitors are powered by a battery. For a more reliable product, you should choose one that comes with a long-lasting battery. This will let you use it longer without the need for recharging. It is convenient if the battery can last several days. It is also important that it does not take forever to fully recharge the battery!


If you are using a bicycle heart rate monitor with a screen, such as a smartwatch or a bike computer, then you need to consider the display. It should be large enough so that it easy to see but without being a distraction or discomfort when worn. The display should also be backlit, which will make it easy to view whether you are cycling day or night. Even if it is lit, it should not consume too much power so that you can save battery.


When it rains, your cycling heart rate monitors must be able to keep up. Choose one that is built to be waterproof. This way, you don’t have to worry even if it gets wet. Consider the waterproof rating, especially if you live in a place where it always rains.


Aside from those that have been mentioned above, below are other features that you should be looking for as you try to narrow down the possibilities for heart rate monitors for cycling. With these capabilities, you can unlock more benefits.

Target Zones

This is an important feature as it provides a better understanding of your cycling workout and your health. At the most basic, a good cycling monitor should offer at least three target zones. In the case of the advanced models, you can find up to six heart rate target zones.

In a nutshell, your target heart zone will let you know if you are hitting your target. If not, then this should give you an idea that you need to do more.

Calorie Counter

Cycling is good exercise for people who would like to lose weight. If this is the case, then you need to spend time tracking the calories that you have burned. This will let you know your progress and inspire you to go further if you need to burn more.
