Key Features To Consider When Choosing The A Mountain Bike Computer

Having seen the top 5 models, we have promised to share the features we considered the most important. If none of these computers are what you are looking for, you can use these features as your own personal buying guide.

Here are the top features to consider when choosing a computer for your mountain bike:

Wired vs. Wireless

One of the first areas of concern is how you will go about mounting the GPS. If it needs to be mounted to your bike, you need to put in some effort to have it fully installed. However, you can find those with a simple bracket and no wiring needed. If you choose the latter, you need to keep the battery power in mind and how often it needs to be charged.

Basic Features

We all know that these computers should have a few basic features included. These basic features include simply tracking your basic stats and helping you to improve. Having an odometer also means that you can track the altitude, while many top models will allow you to navigate the gradient efficiently and reduce the power output.

GPS Technology

For a bike computer, GPS technology is not as important as many other tech models. However, having it will make a massive difference. With GPS technology, you can effectively measure your distance and also see where you are on the map. Brands like Garmin specialize in GPS technology to make it easier for you to keep your location data accurate.


The bike computer has been evolving and can almost rival your mobile device. With APP integration, users are allowed to share some of their stats and data on social media directly using the APP. You need to ensure that you choose an APP that will be compatible with your device. Additionally, Strava Live Segment will help you set up small challenges and this could motivate you to push even harder and potentially improve your own records.


Since we can’t always predict what will happen, the durability factor is something that needs to be kept in mind. You might not fall, but when you do, you want the computer to hold up and this is why top brands are adding rubber coatings. Additionally, you might need to look for a waterproof rating that is included. Most Garmin bike computers already have a waterproof rating of around IPX7 to keep you protected.


A bike computer is not an essential part of the bike and might not even have the same importance as something like the chain or your grips. However, it does make life a little easier when it comes to stat tracking.

When it comes to choosing the best mountain bike computers, we have found the Garmin Edge 810 GPS Bike Computer to be elite in all aspects and it has an affordable price.

We would like to thank you for reading this article and encourage you to share some of your thoughts. Let us know which of these mountain bike computers have served you the best and if we might have missed any of your favorites.
