Guide Review - Polar S520 Heart Rate Monitor & Cycle Computer - Polar S520 Product Review

We tested the Polar S520 cycle heart rate monitor in all sorts of weather and riding conditions and never had any performance issues.

The Polar S520 heart rate monitor and cycle computer is easy to set up and provides you with all the training and fitness info you need for most workout and training programs. You can even transfer training data to software on your PC.

Out of the box, the Polar S520 cycle heart rate monitor comes with everything you need to set up your bike. As far as cycle features go you get: trip length, speed (incl. average and max), distance based intervals, distance based recovery, and wheel size settings for two bikes. You can also purchase an optional cadence sensor.

Its the heart rate and fitness features are what you really pay for with the Polar S520. Rather than explaining it here, I will leave explaining the benefits of training with a heart rate monitor to another resource. However, I will note the S520 has all the features that most people will ever need for this type of training.

I was most impressed with the ease of setup with the Polar S520 heart rate monitor and cycle computer.

If you know you want a heart rate monitor and not just a cycle computer, the Polar S520 is a good affordable choice. If you don't really care if you have heart rate monitoring capability, just get a standard cycle computer and save yourself a couple hundred dollars.
