Polar – Mio – Fitbit. The Best Heart Rate Monitors for Biking

Biking is a fantastic exercise that allows you to see the outdoors while burning calories.

In order to monitor your heart rate, you need one of the best heart rate monitors for biking.

What to look for in a heart rate monitor for biking

So, you want a heart rate monitor to bike with? Well, there are specific things you should look at in order to choose the best one. This isn’t just some easy decision where you go to the store and buy one right off the shelf; heart rate monitors range in price and can be quite expensive.

You want to make a smart decision and purchase one that is going to be able to last a long time because it is made out of durable material. What use is a cheap product if it breaks down within the first month? This is why it is important to know what to look for in order to avoid loss of money.


The first thing, and this is the most important thing no matter what you are doing, is accuracy.

Heart rate monitors are useless if they aren’t accurate enough. If you are biking and your heart rate is testing way higher than normal, you may feel alarmed or may start biking slower, but if this reading is wrong, you have wasted your entire workout. It is crucial that you get high-quality heart rate monitors that can test the rate in REAL TIME.

The information is useless if it is slow and reports with a delay; you need to have real-time statistics in the moment to help you plan your workout and plan different intensities.

Since you are looking for the best heart rate monitor for biking, you need one that has been manufactured specifically for this type of work out. The best thing is if it is GPS enabled and can work at high speeds with the GPS. This means it will be able to track your speed, the distance traveled, the route taking, the altitude, and then log it all for you right away.

The best monitors can sync directly with apps on your smartphone or your computer, so you can see your route and how fast you’ve been traveling. This allows you to plan your next workout and the goals you want to achieve while working out. Ask any personal trainer about goals, and they will say they are the most important things while working out. It allows you to keep pushing yourself to enhance your cycling experience.


The last thing to look at is the look, even though it is still important.

  • You never want to feel like your monitor is hindering your biking experience.
  • It cannot be in the way and it must be lightweight and not slow you down; it should not even feel like it is on your wrist.
  • The best ones are also resistant to the sun, so they won’t overheat while biking, and also water resistant in case you get caught in the rain.
  • We can’t control the weather while we are biking, and sometimes unexpected things can happen, so buy a heart rate monitor that is going to last.
