Best Watches For Mountain Biking

Watches are clever things these days and are not just used to count down to lunch time anymore. There are lots of smartwatches on the market that are oozing with features, but not all of them are suited to mountain biking. In this post, I am going to go through the best watches for mountain biking.

Why Can't I Just Use My Phone?

Mobile phones are great for monitoring your rides. The amount of apps available make your phone very versatile. There are arguments for and against using your mobile phone over a smartwatch.

Reasons For Using Your Phone

  • Price – Most people already have a smartphone, so it. ay not be at the top of everyone’s list to buy another piece of electronics. This is especially the case when fitness apps are generally quite inexpensive.
  • Apps –  By downloading various apps, you will be able to make your phone do similar things to what a smartwatch can do. You can get apps that track your speed, distance, time, how much work you are putting in etc. All this is done by pairing your phone up with heart rate monitors and various other sensors.

Reasons For Buying A Smartwatch

  • Convenience – A smartwatch is small, light and sits on your wrist. This means that you don’t have to take your phone out every time you want to check your location, the time or even for notifications.
  • Battery life – GPS, bluetooth etc zap the battery power on your phone. If you are riding in cold weather, the battery life is reduced dramatically too. Some GPS smartwatch batteries can last 20 hours. This means you can continue to monitor your rides and still have your phone working for emergencies.
  • Accuracy – The accuracy of the GPS sensors in a smartwatch is much more accurate than in your phone. This is why you may notice a discrepancies between you and your friend’s Strava data.
  • Waterproof – When it is raining, it is best to keep your phone safely tucked way in your bag or waterproof pocket. Smartwatches are much better as they are properly waterproof and some can even be used while swimming.
  • Replicability – Watches are very secure on your wrist, so the chances of you losing them is pretty slim. But, if you manage to lose or break it, it isn’t as inconvenient as losing or breaking your phone, as your phone is used more in your day to day life.
  • Versatility – Depending on which watch you buy, the features available make them very versatile. They can be used to monitor your performance in all sorts of sports and activities.

In conclusion, if you are not too serious about monitoring your rides, a smartphone app or two will be enough. But if you want accuracy, convenience, security and safety, a smartwatch is the best option.

A very feature rich watch, the Forerunner 245 has a lot for such a compact and lightweight item. It isn’t the cheapest watch on the market, but it should deliver pretty much everything you’d need from a fitness tracker as long as you’re not super serious about your training.


  • Lightweight and unobtrusive design
  • Super comfortable, even during sleep
  • Great battery life


  • Doesn’t have a premium feel
  • Sleep tracking could be more accurate
  • No triathlon mode or Garmin Pay

The Garmin Forerunner 245 has been updated so it tracks more sports than before. you can track now strength training and swimming. Other improvements over its predecessor give you better feedback on your training to help you tell if you are working as efficiently as you can. In addition to this, it gives you daily stress insights and tells you if should be resting or not, with Garmin’s Elevate heart rate sensor. One of the most useful upgrades is the battery. It now lasts more than twice as long as the old version when GPS is in use.

The Forerunner 245 is designed for providing fitness tracking data to those who workout often but aren’t trying to be become a super athlete. It has a good number of sports tracking capabilities but not at the expense of the Fenix 5.

It is lightweight and doesn’t look or feel too obtrusive on the wrist. But its plastic construction doesn’t have a premium feel. It is much smaller in comparison to the Fenix series too, at at just 38.5g with a 30.4mm diameter face.

The lightweight design and silicone strap makes the Forerunner 245 extremely comfortable when wearing it. For mountain biking, this is pretty important, as when you are riding bumpy terrain, heavy watches wobble around on your wrist, proving very uncomfortable. However, its size is still good enough to make it easy enough to look at your performance data.

It is controlled using the side buttons, rather than a touch screen. This works better for many sports, especially in water and is good for battery life.

The Garmin Forerunner 245’s 1.2″ screen is sharper and has better detail than the 235. It is easy to read essential information, such as timings, heart rate information and elevations even in direct sunlight. In the dark you can use an LED backlight at the touch of a button when required.

The Garmin Forerunner’s preset tracking setting include running, trail running, indoor track running, yoga, cardio, treadmill, cycling, indoor cycling, indoor rowing, walking, indoor walking, elliptical, and stair stepper.

But now, you can also track pool swimming and strength workouts. The functionality allows you to create your own workout too and you can add whichever tracking tools you’d need to monitor it, such as GPS or heart rate monitor.

For mountain biking (or running for that matter), the Forerunner has all the standard tracking tools to monitor distance, speed, and pace. Garmin have made it super easy to customise the data that you want to see on the screen without having to go into the app.

Who Is It For?

The Forerunner 245 is a great for those who take exercise more seriously than somebody that likes to go for a jog. However, it isn’t ideal for the more adventurous people. For this, you should probably go for the Fenix series of Garmin watches.

A very capable watch for keeping tabs on your fitness goals the Polar M430 has a reliable wrist-based heart rate monitor, accurate GPS tracking and sleep tracking.  It also displays smartphone notifications to create one of the best mid-range smartwatches to buy.


  • Good battery life
  • Easy to use
  • Reliable and accurate


  • The appearance may not be to everyone’s taste

The Polar M430 is the updated version of the M400. It looks quite similar to the older version, but it has some added features to bring it bang up to date.

The addition of a built in optical heart rate monitor, improved GPS and new sleep tracker, makes this a good value for money watch. It is probably the best mid-range smartwatch for tracking your fitness and mountain bike rides you can get. 

It doesn’t have a colour touchscreen, like you would find on the Garmin options above, but the M430 is a capable piece of wearable tech. It has all the basics a fitness watch should have, such as pace, distance, speed and cadence. The built in optical heart rate monitor allows for day to day activity tracking, advanced sleep tracking, fitness tests and recovery time tips. You get all this data when you sync it up to the Polar Flow App or Web tool.

The M430 is suitable for mountain bikers and anyone that wants to improve their general fitness and reach their goals. This watch is simple to use, but is loaded with tech. Which makes it a cheaper alternative to the Garmin Forerunner. This makes it one of the best fitness watches you can buy at the moment.

The M430 looks fine to me, but it may not impress the more style oriented people out there. Style isn’t at the top of Polar’s list with this watch, as it is primarily a tool for exercise.

The M430 has a monochrome-style display with no fancy colour touchscreen. But don’t let that put you off, as screen is clear and easy to read in any light conditions. There is a backlight for using it in the dark, but you can also invert the display to make it easier to read in low light.

The M430 is much more comfortable than the previous M400, as it uses a new softer silicone for the strap. This new material is also breathable and has a more ergonomic design for a better fit.

As this watch doesn’t have a touch screen, you control it using its five buttons. Each one has its own function and they are very easy to use on the move.

There is a huge amount of functionality with this watch, but a nice little touch that you might like, is the customisable watch faces. You can choose from five different layouts to suit your personal preference.

As a mountain biker, you will be interested in how good the GPS is. It works well, especially when you sync your watch regularly. This means you get the latest A-GPS data. 

The GPS gives you all the usual data, such as pace, speed and distance along with GPS-based altitude. Bonus features you may like are the sleep tracker, fitness test, VO2 Max and daily activity tracker.

Who Is It For?

The Polar M430 is a great watch for anyone who considers themselves to be fitness goal-driven. It will help you no matter what level of fitness you are and I great for monitoring your mountain bike rides.

Suunto Ambit 3 Vertical

Best Watches For Mountain Biking

Features & Specifications

  • GPS capability
  • Comes with altitude profile
  • Tracks your vertical gain from yearly total to, day by day
  • 15 hour battery in GPS mode
  • 5-second GPS accuracy
  • Measures speed, pace and distance
  • Includes compass



The Suunto Ambit 3 Vertical is a great choice for people who prefer a watch over using their phone or a GPS computer on their bike. It can track any metric you want, including power.

The user-interface isn’t as smooth as the Garmin Fenix and there have been reports of unreliable Bluetooth syncing. But these issues shouldn’t put you off being one, as they are not deal breakers.


  • Looks great
  • Comfortable
  • Works with power meters
  • Real-time elevation profile


  • Bluetooth sync not great

The Suunto Ambit 3 Vertical is a stylish GPS-enabled watch. Its tough build quality is ideal for mountain biking and other outdoor adventures.

The GPS antenna is hidden in the bezel, making it a much more stylish watch than other Ambit watches. It is also available in white, blue and black.

The silicone rubber strap is pliable and extremely comfortable. It texture is nice and slippery, which means it doesn’t catch on your arm hair like some straps do.

It has an LED backlit screen, which is quite small. However, it is very sharp and easy to read in different light conditions. The watch is controlled with its five buttons around the bezel instead of a touch screen. This means you can keep your gloves on to change screens or start/stop and activity.

The Suunto Ambit 3 has modes for cycling, mountain biking, and generic heart-rate-based indoor training. In addition it has modes for other activities, such as Ski Touring and Triathlon. You can customise these modes using the Movescount app and you can create new ones too. You can even change between sports mid-activity.

The battery lasts 15-hours using the five second GPS accuracy mode. This is extended to 100-hours with GPS reporting reduced to one minute. The Ambit 3 Vertical can also access the Russian GLONASS network for pinpoint GPS accuracy.

The Ambit 3 Vertical is Bluetooth enabled so it can be link up with Bluetooth heart rate monitors and power meters. There have been reports of it taking a few attempts for bluetooth pairing. But once it connects to the devices, activities are uploaded instantly via Suunto’s training software, Movescount. This works well with third party applications like Strava.

This app is easy to use, with the dashboard displaying a summary of your activity over the past, with a list of all your recorded ‘Moves’, which are divided up by activity type.

The Bluetooth connection also allows the Ambit3 Vertical to display on screen notifications from your phone. If you want it to, you can set it to vibrate to alert you to notifications from Instagram and Twitter. Although I suggest you switch this off.

GPS accuracy for riding is good thanks to the option of using GLONASS. It also locates the satellites quickly. After each activity the Movescount app allows you to make Suunto Movies.

When it comes to navigation, the Suunto Ambit 3 Vertical has a breadcrumb-style navigation.  This is very accurate, but it isn’t as easy to read while on the bike as the Garmin Fenix 5. However, it can keep track of up to 250 points of interest (POI), and it will alert you to them by vibrating as you approach one.

Once your activity is finished the Movescount app allows you to make Suunto Movies. These show your route on a map and let you know stuff like where you were at your peak heart rate, where your fastest kilometre was and peak altitude. Like Strava, you can add in any photos of your ride.

Who Is It For?

The Suunto Ambit 3 Vertical is a cheaper alternative to the Fenix 5. The controls are not as intuitive, but you may like the Movescount app and the Suunto Movies, to geek out on your data in an easy to follow way.

If you are a mountain biker or a roadie, the Suunto Ambit 3 Vertical is a great option to monitor your rides and pretty much anything else you do.

Things To Consider When Buying The Best Watch For Mountain Biking

The watches above are great options and you can’t really go wrong with any of them. But which one you choose will be down to a few different things. Now I will go in to the things you should look in to when buying the best watch for mountain biking. You just need to realise that you will have to compromise on something, whether that be spending more or sacrificing certain features.


The best watches for mountain biking will connect to devices such as heart rate monitors, cadence sensors and power meters. This connectivity will give you all the data from your ride possible. Therefore, most watch manufacturers enable their watches with Bluetooth. This means you can also use phone 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. So, before you buy the extra accessories, you should look in to what type of connectivity they use to make sure they are compatible.

Many mountain bike watches have WiFi connectivity too. Therefore you can  sync your data without needing to connect it to your phone or computer.


All of the watches above have GPS built in. This means that you don’t have to connect your phone to use its GPS. For extra accuracy, look for watches that have the Russian GLONASS built in.

Battery Life

Most watches have a battery life that last weeks, but this all depends on what you have connected to it and the mode you have it set to. 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.


The best mountain biking watches have a toughened mineral glass screen. Most of them have straps that 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 that are controlled with touch screens are great. However, if you have fat fingers, they can prove to be a bit awkward. Also, they are not always that easy to use when they are wet. But one of the main issue with touch screens, is that some 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


Many watches are suited to multiple sports and activities, depending on their built in sensors. For mountain biking, the most note worthy sensors are, altimeters, barometers, accelerometers, heart rate monitors, compasses and gyroscopes. But obviously they are useful for other activities such as hiking, climbing, skiing, snowboarding etc.

Watches with built in heart rate monitors work by shining LED lights through your skin. This detects the blood pulsing through your veins. Therefore, you need to make sure that the strap is in proper contact with your skin, to get accurate results. This is why the silicone straps are so soft and ergonomic.

    This is a great article about the best watches for mountain  biking . I agree with you on the fact that smartphone though provide more resources when it comes to mountain biking , but they are in many ways not convenient.  I think one has to stop constantly in order to consult his or her smartphone.  While a smartwatch offers more comfort.

      Hi Randy,

      Thanks for your comment. You are right the convenience of a watch makes navigating easier and your phone will keep its battery power for when it is needed in an emergency.

    The days when an old fashioned  analogue watch  where you only get time. You need more information now without draining your  power from your mobile phone. I can understand that you want a device that is easily accessible, has good gaps and helps you if you get lost. You have present some very distinctive smartphones that I can see most mountain bike users will like, as long as they can take the rough terrain that you find yourself in and the tumbles that can result. I think you have researched the smartwatches well. My question is how likely is the smart watches to fail especially if you are caught in an inaccessible area?



    • 20/03/2020 at 7:49 pm

      Hi Antonio,

      Thanks for your comment. When you say “fail” I am assuming you mean with GPS reliability. They are pretty good these days and rarely drop out for long enough to be a real problem. Watches with the ability to connect to the Russian GLONASS system are more reliable, as they can flip between systems.

  • 20/03/2020 at 7:39 pm

    Hi Tom – It is very timely that I am reading this post.  I am not a mountain biker but I am a walker.  I am currently using a pedometer app on my smartphone and I am becoming increasingly concerned because it gives different step readings for the same routine.  This addresses the accuracy point that you bring up.  So I am going to consider upgrading to a smartwatch.  I am liking the Garmin Fenix 5.  Thanks for this info!

    • 20/03/2020 at 7:46 pm

      Hi Nathaniel,

      Thanks for your comment. The Fenix 5 is the best watch here and would be great for hiking.

  • 21/03/2020 at 1:19 am

    I also had this dilemma. Should I really buy a smartwatch for this or will my phone do the job. The first thing that came to mind is that I could save the money the smartwatch would cost. But there are so many advantages of purchasing the watch  (among the most important for me are: accuracy and versatility) that I’ve decided to purchase the Garmin Fenix 5!

    Thanks for helping me make up my mind!

    • 21/03/2020 at 9:50 am

      Hi Paolo,

      Thanks for your comment. You will get the use out of a watch too, as you can wear it all the time and it will last you years.
