What Does A Bike Computer Do?

Before we look at how the bike computer can help your cycling journey, we should think about what the purpose of the bike computer is. We have listed a few of the most important factors that a bike computer should be capable of doing when you are cycling. This could make huge differences to some people:

Stat Tracking

One of the most important features of the bike computer is tracking your stats and this also translates to your performance. The bike computer manages to use different statistics that are available from the bike and sensors like tracking your cadence. It can help you control and regulate the power output on the mountain bike.

GPS Tracking

Having the help of a GPS module can help you control the distance and the direction in which you are moving. It is essential that you can track your stats efficiently and see in which direction you should be going. The GPS configuration will ensure that you never get lost, which should make life so much easier on the bike.


One of the biggest benefits and areas where the bike computer will be used the most is when it comes to training. You could use all the features effectively to ensure that you improve your training and even enhance the way you deal with altitude if you have an odometer. Some of the high-end bike computers will feature a built-in form of software for training.

Energy Control

Finally, the more advanced bike computers offer energy control and they will allow you to track how much energy you have been expending this helps with making sure your energy levels are controlled. In terms of the triathlon, it can often be tricky and you might not have accurate control measures when it comes to this.

What Are The Benefits Of A Bike Computer For Triathletes

Now that you have seen what purpose the bike computer fulfills on the bike, you might be wondering out it will affect your performance as a triathlete. Fortunately, the bike computer is a functional piece of cycling equipment. It offers good value for your money and should help make life a bit easier when cycling:

  1. Management

One of the biggest benefits of the bike computer is management. If you don’t know what you are doing, it is almost impossible to improve on anything. Once you have an idea of how much effort you are putting in, you can start to pace yourself. You must always consider pacing to ensure a constant effort that will yield more benefits.

  1. Distance Management

Some of the top bike computers will allow you to plot your routes. This enables you to enter some of the metric targets you are looking to hit. If you want to speed up in certain sections, you can plan and plot this on your bike computer. You can set yourself certain bike targets that should make life slightly easier when you are riding.

  1. Preparation

One of the most important things that go into winning any competition is that you need to be prepared. One of the best ways that you can prepare is by having some form of computer that will assist you. The top bike computer will make this possible and you can use it to plot distances and manage your effort. Unfortunately, you might need a good computer and this could be expensive.

  1. Various Modes

While not all bike computers will offer you access to different modes, there are a few that will. Some of the top options will give you the walking mode, which should help with the running part of the section. Once you can manage things like your running, you can even improve your performance in those specialized areas.

Keep in mind that not all bike computers are the same and some of them do not offer you the benefit of these different modes for your performance. Having a feature for swimming is often not available and you should consider a smartwatch from brands like Garmin with this feature. These watches could complement and be interlinked with your bike computer.

Limitations Of The Bike Computer For A Triathlon

Unfortunately, the bike computer does not always offer benefits only. The bike computer might come with a few limitations that you often need to deal with. Understanding these limitations can help you determine whether a bike computer will help with a triathlon. As you might have guessed, certain bike computers tend to be expensive:


One of the first things to keep in mind is the price. While you can easily find the best bike computer for under $100, it is limited in terms of features. Some of these computers are only programmed to work with bicycles and they might be lacking when it comes to features. The top-of-the-range options tend to be overly expensive.

Feature Limitations

If we look at the setup of a triathlon, it involves three different disciplines. While the bike computer can help you with the cycling part, it might be lacking when it comes to running or swimming. The bike computer does not account for these slow speeds and it might even pause. Having an additional tracker like a fitness watch can be very helpful.


Even with many of these warnings, some people still choose to use the bike computer for things like running and swimming. The problem is that many of these statistics tend to be inaccurate and you could find that they do not paint the full picture. Unfortunately, this means that the bike computer can be unreliable for triathlon athletes.

How Do I Use A Bike Computer For A Triathlon?

If you want to use a bike computer for your triathlon, you will need to make sure that it is adjusted to meet all your needs. You might want to settle for one of the older Garmin models that feature the walking mode. It can be daunting to calculate the differences in your head and this will make it harder to use.

Alternatively, there are many great Garmin fitness trackers and watches available on the market. Many of these can be adjusted to account for swimming, running, and cycling. They should make life a bit easier and ensure that you can readily track your stats more accurately. These watches can replace the bike computer.

However, the bike computer is far more accurate in the cycling aspect and if you can only use it for cycling and especially training, you should see bigger improvements in your performance and fitness. You should be able to notice these massive differences in performance and you can use them to improve your overall pace.

Should I Buy A Bike Computer?

We love the concept of the bike computer and certainly believe that it could make a difference. The bike computer is designed with some incredible features that will make your life that much easier. If you are serious about being competitive in any sport that involves cycling, you should consider a good bike computer. 

Those who specialize in cycling might find that the bike computer can be perfect for them. Since it offers a way of measuring performance, the adage comes into play. If you can’t track something, you cannot improve it and this will be the case with a good bike computer. We would highly recommend that anyone into cycling considers one.


A bike computer is a diverse tool that offers to improve performance and give you value for your money. If you want to be one of the best cyclists, you should consider buying a great bike computer. It might not always be the best investment for triathletes, but still offers value for your money. Let us know in the comment section how the bike computer has assisted you.
