Best GPS Watch For Mountain Biking ( Garmin, Polar, FitBit, Apple & More )

Every serious biker knows that the top watch for cycling must have the features that will match their strenuous activities.

While there are a lot of watches in the market that are made specifically for mountain biking, not a lot has what bikers need.

Today, I will share some of the best watch for mountain biking which also includes garmin, fitbit and more brands.

And, that’s just what we’re here for. To help narrow down your choices for the best smartwatch for mountain biking.

Things you need to care when buying MTB Watch

Let’s be honest. The market for smart watch is heavily saturated with cut-throat competition.

With so many options, how do you select the most suitable MTB watch that you are looking for?

This section is going to explain everything and I will share my personal favourite steps that will help you to pick the right one.

Just keep in mind – No product is perfect and you won’t be getting all the features in a single device. But the following options are definitely going to cut your confusion.

1.Water Resistance Capability:

No matter what device I pick, the very first thing I look is – Water Resistance Capability. If you’re into outdoor riding, you will need something which won’t disappoint you after a little rain.

I must say, not every MTB watch is going to be water resistance but when you see, I would highly recommend to grab that ASAP.

But again, don’t think too much if you can’t find a water resistance watch because sometimes, popular product goes out of stock for months.

If you find that’s good. If you can’t, move on.

2. GPS Capability:

Nowadays, we all have smart phones and don’t need GPS right? Well, I would like to have a GPS capability option on my device as I don’t want to drain my phone battery.

It’s a good option to have and when you go on mountain biking, sometimes you go for way too miles without realizing that you’re far away from start point. Having a map at that time just a life saver.

3. Value for Money:

I am ready to spend good amount of money on something I really care about. But definitely don’t recommend spending more than you can afford.

Here’s another thing to consider.

You also need to aware that better price does not mean great value. Sometimes, lower end products can perform really good compared to expensive ones.

The listed item I just shared are all categorized with taking consideration of price and value at the same time.

I don’t like to pay for some gimmick features I will probably never use. So do you!!

4. Notifications:

You’re in a zone of super sporty mode and riding your bike so passionately and suddenly your phone beeps up.

Well, I know you can’t stop for checking every notification you get.

So pick something that will allow you to view calls & messages on your watch screen.

5. Fit & Usability:

I know you’re excited to grab your watch for next mountain biking season. But apart from that, how do you plan to use the watch?

See, the majority of the devices out there are really good for daily use.

You need to pick something that would fit in your zone/lifestyle so it can blend easily.


Tracking your bike ride is important especially when you want to improve yourself as a cyclist. This keeps you a tab on the distance you traveled and how fast you did on that ride.

Most importantly, it lets you know whether you’re improving or you’re slacking.

With the smartphones dominating the gadget market, claiming they can keep track of almost anything, they still can’t beat the smartwatch that is intended for such situations.

It may have GPS but, not heart rate monitors, sensors, barometers, etc.,

Which, our top pick, Garmin fēnix® 5 has and more.

Garmin fēnix® 5 is considered as Garmin’s most popular smartwatch from their line of complex timepieces. All the features you need for a smartwatch and activity tracker is packed in a sturdy constructed watch.

Garmin fēnix 5 is perfect for hikers, backpackers, mountaineers and just about anyone who are engaged in more than one sport.

Do not mistake this as just a sporty watch. Its robust frame with different colors to choose from of straps also makes it a watch you can wear while you sit comfortably in your office.
