How We Pick Heart Rate Monitors

There are many options out there for a heart rate monitor these days. In order to pick the ones that are truly good, we turned to online cycling forums, asked around in bunch rides, and also looked at what the pros are using.

So, in picking our favorite cycling heart rate monitors, we paid attention to the criteria below :

  • HRM Type. We only picked chest straps heart rate monitors. There are other types that are worn around the wrist or arms. In our opinion, these don’t work that well for cycling.
  • Accuracy. There are 2 technologies used in heart rate monitors. Electrocardiography (ECG) is used in chest straps and photoplethysmography (PPG). We picked only those that use ECG as they’re more practical (chest straps) for cycling and have better accuracy.
  • Connectivity. All our picks support ANT+ and/or Bluetooth. You’ll need these to connect to your bike computers to display your heart rate reading.

Wahoo offers high-tech products for cyclists and runners. The Wahoo Tickr is currently the most popular heart rate monitor that supports dual-band technology.

That’s ANT+ and Bluetooth compatibility. You can easily tell if it’s working with the LED lights. It lights up blue when it’s connected and red when it’s detecting your heart rate.

And best of all, it’s one of the few heart rate monitors that are waterproof with a rating of IPX7 (up to 5 feet deep).

  • Pros : Dual-band ANT+ and Bluetooth is compatible with all bike computer models, regardless of the brand.
  • Cons : Expect to pay more over the other models.

Hammerhead Heart Rate Monitor

Launched without much coverage compared to the Karoo 2, the heart rate monitor is Hammerhead’s latest addition to their product lineup. There is no doubt that Hammerhead will continue to expand its product lineup aggressively after successful recent funding that includes 4x Tour de France winner Chris Froome the CEO of Zipp wheels.

This heart rate monitor is both Bluetooth and ANT+ capable. It can connect to the Karoo 2 on either method, but the ANT+ method will significantly increase the CR2032 battery lifespan.

The good news? You can get it for 50% off when purchased with a Karoo 2.

  • Pros : Very sensitive electrodes. Made of silver instead of polymer in other brands.
  • Cons : Premium pricing if bought individually.

Garmin Premium Heart Rate Monitor

The Garmin Premium HRM comes together with all Garmin Edge devices if you buy them in the bundle.

You’ll probably notice that there are several variants of the heart rate monitor. This model is specific for cycling and if you’re into other sports such as running and swimming, consider getting the HRM-Tri instead.

Connectivity-wise, only ANT+ is supported and it’ll work with all head units that support ANT+.

  • Pros : Comfortable chest strap made from soft fabrics.
  • Cons : Not Bluetooth compatible.

Polar H10 HRM

Are the heart rate monitor straps replaceable?

Most heart rate straps are replaceable since the sensor unit can be easily removed.

When you’re buying a replacement chest strap, make sure to check that it’s compatible with your sensor unit. Sizing wise, it’s adjustable, and one size fits all. So, you don’t have to worry about that.

Some generic ones are compatible with all the major heart rate monitor brands.

Are heart rate monitors waterproof?

It depends on the model.

It’s best to read the manufacturer’s exact specifications. But in general, all heart rate monitors are water-resistant at the minimum.

Those which are waterproof cannot transmit real-time heart rate readings due to how the technology works. ANT+ and Bluetooth use the 2.4Ghz microwave frequency band for transmission, and these radio signals are easily absorbed by water.

Can I use a wrist based heart rate monitor for cycling?

Yes, you can. But I wouldn’t recommend you to do that for the reasons I’ll explain below.

  • Fit. A wrist-based heart rate monitor doesn’t fit as snugly as a chest strap. Your hand movements will cause it to move around and hence affecting the reading.
  • Real-time display. While the wrist-based heart rate monitor collects readings, they typically don’t sync with your GPS unit. Hence, you’ll need to keep glancing on your wrist to see your heart rate, which can be dangerous, especially if you’re riding in a group.
