Desirable Smartwatch features

A built-in GPS is essential for using a smartwatch outdoors. It makes it easier for cyclists to navigate different places and makes the tracking of attitude gain, location, and distance much more accurate. Mounted bike computers often cost extra, so making sure your fitness tracker has a built-in, accurate GPS will eliminate this extra cost.

Probably the most important feature, long battery life is essential for outdoor watches. This is for the simple fact of not being able to charge them when out and about. The minimum that a smartwatch should last between charges is one week.

Comfort is so important when choosing a fitness tracker. The last thing you want is to spend a ton of money on a watch, only for it to be super uncomfortable. Make sure you pay attention to the watch strap, as this can seriously improve or reduce the level of comfort. It is also important to make sure the watch isn’t too bulky.

Most smartwatches have advanced health tracking features such as a heart rate monitor, pulse oximeters (SpO2), hydration monitor, stress monitor, and sleep monitor. These are helpful when mountain biking as it helps you to stay in control of your health and performance.

Some fitness trackers have a lifesaving, fall detection feature. This feature sends a notification, along with your location, to your emergency contacts if you suffer a bad fall. However, not all fitness trackers have this feature, so look for it.

Our Recommendations

While the best watch for you is a matter of personal preference, we’ve gone ahead and reviewed dozens of smartwatches at a variety of price points. Here we break down the pros and cons of more than a dozen fitness trackers to help you decide which smartwatch best suits your goals and needs.
