Here is my guide to help you choose the best mountain biking GPS watch. Tracking your ride with one of these is a great thing to do. We can see how we improve as riders, keep tabs on our distance traveled or how fast we did that downhill run in the alps. But more importantly, rub our mates nose in it after beating their time.
It is possible to track all this with our smart phones, but a GPS watch is a far more accurate way of doing so. Scroll down to see my top picks for the best mountain biking GPS smart watches.
The best mountain biking GPS watch will connect to heart rate monitors, cadence sensors and power meters. As a result you get extra data from your ride. Consequently, most brands use Bluetooth, allowing connectivity with your phone, utilising apps to sync your data.
Garmin use a similar system to Bluetooth, called ANT+. Therefore, most of their devices are now compatible with Bluetooth accessories now. Therefore, if you have some of these accessories, it is worth finding out what method of connectivity they use before buying the watch.
There are lots of these watches that have WiFi connectivity too. Therefore you can sync your data without needing to connect it to your phone or computer.
These watches have GPS built in, hence you don’t need to connect your phone to it to receive the GPS. Additionally, many of them have the Russian version of GLONASS built in too. As a result of this , you get extra accuracy, as they use either system as it is needed.
It would be pretty pointless having a watch that keeps going dead. Most of them have a battery life that will last weeks, however this all depends on what you have connected to it. You also need to check the “in activity” battery life. This is when the GPS is working during your ride, and it can deplete the battery quite quickly.
What it is made of?
The screen isn’t much use if it is scratched, so the best mountain biking GPS smartwatch will have a toughened mineral glass screen. For the most part, straps are made from silicone, making them very comfortable. But you can change the straps for leather or metal versions, for when you are not in your biking gear.
Watches with touch screens are great, however they can be a bit awkward for those riders with larger fingers. They are not always that reliable when they are wet either. But one of the main frustrations is, that some models don’t work while you are wearing gloves.
Models with buttons on the side have their advantages, but make sure that you can ‘lock’ the buttons. This is because you can easily press them by accident, pausing your ride.
You can use many of the watches for different activities, due to their built in sensors. The most note worthy sensors are, altimeters, barometers, accelerometers, heart rate monitors, compasses and gyroscopes. Consequently, these make the watches useful for hiking, climbing, skiing, snowboarding etc. They are also waterproof for when you want to go for that triathlon you have always wanted to complete.
Heart rate monitors built in to the strap work by shining LED lights through your skin. As a result, the watch detects the blood pulsing through your veins (how clever is that?!). Therefore, you need to make sure that the strap is in proper contact with your skin, to get accurate results.
