FAQ - Bike Computers & GPS Systems

What is a bike computer?

A bike computer is a sensible investment in any case if you like to get around by bike. It does not matter whether you simply want to go on excursions near your home or even plan extensive cycling tours at home and abroad. With a navigation device for your bike, you are well equipped and no longer have to study conventional maps.

A bike computer is a device that was specially developed for the needs of cyclists. Basically, it hardly differs from a classic car navigation system, except that it has just been optimized for use on a bike. The devices were designed accordingly and are not least characterized by their compactness and robustness. A good bike computer should definitely be waterproof.

The functionality of a bike computer is comparable to that of a classic navigation system. The built-in GPS allows your location to be determined precisely and calculating the optimal route to your desired destination is easy for the device. It is common for it to be operated via a touchscreen screen. The operation should not be a big challenge even for amateurs.

Why do I need a bike computer?

Depending on which model you choose, the range of functions of your bike computer will differ. It is therefore important that you get a good understanding of the devices before you buy. You should also think about which functions are most important to you personally. Typical features of a recommended bike computers are:

  • Navigation via GPS
  • Electronic barometer for height measurement
  • Electronic compass
  • Round trip function
  • ANT + connectivity
  • Micro USB connection
  • Bluetooth

In addition, ideally, the largest possible map material should already be pre-installed so that you do not have any additional effort in this regard. Connected features such as smart notifications are also practical and help you make handling a little easier. It is also highly recommended to opt for a bicycle navigation system with an integrated accident notification. If you have a crash with your bike, certain people will be automatically informed about this incident in advance. This is not only great for your sense of security, but can even save your life if in doubt.

Most modern bike computers are designed in such a way that they are expressly not only suitable for cycling, but can also be used for all kinds of other activities. Whether you like hiking or geocoaching, the navigation device can provide you with valuable services for these hobbies. Simply select the appropriate activity profile such as cycling, mountain biking, geocoaching or hiking and get the ideal support in terms of navigation.

Advantages & Disadvantages of Bike Computers

Before you buy a GPS device for your bike, you will surely think about what actually speaks for and what speaks against it. For this reason, we have summarized the most important advantages of such a device for you in an overview:

  • Assistance in planning bike tours
  • Intelligent navigation on the ideal route
  • Call up and evaluate information on distance and speed
  • Localize rest areas and restaurants along the route in no time
  • Suitable for activities such as geocoaching or hiking

Ultimately, these undeniable advantages are offset by very few disadvantages. The battery life of some devices is still expandable and of course you have an additional valuable item with you on your tours, which you should always keep a close eye on. If you take a longer break, when you cannot see the bike directly, you should rather take off the navigation system and carry it with you.

What is the best Bike Computer?

Anyone who has not yet dealt with this topic will surely ask the question: What is the best bike computer? It is clear that a general purchase recommendation for such a product cannot really be given. After all, every consumer has their own preferences and expectations for such a device. So it definitely makes sense to take a look at the different types of bike computers that are currently on the market. A distinction is essentially made between three different variants:

  1. Bike GPS Navigation Systems – these devices have been specially developed for cyclists and are optimized for weight, size and features.
  2. Outdoor GPS Navigation Systems – they can not only be used for bicycle navigation, but can also be used for other purposes such as hiking or geocoaching.
  3. Classic Bike Computers – these devices are characterized by their compactness and offer various basic functions such as measuring the length and speed of the route. However, they are usually not suitable for correct bicycle navigation.

So if it is only important to you to know how fast you drive and how many kilometers you cover on your bike tours, then a simple bike computer will be sufficient. A proper bike computer, on the other hand, should be interesting if you are concerned with things like professional route planning and quick and accurate navigation. If you not only like cycling, but also do other sporting activities, it is worth considering the purchase of a multifunctional GPS navigation system.

Who are the main manufacturers of Bike Computers?

Before buying a bicycle navigation system, you will also deal with the question of which manufacturers offer such devices at all. There is now a pleasing variety here, so that you are not dependent on just a few brands. For example, the Garmin bike computers are among the most popular, but other companies are also represented with various models. The most important manufacturers in terms of bicycle navigation systems include:

  • Garmin
  • Cat eye
  • Hiland
  • Sigma
  • Teasi

But names like Polar, VDO or Xplova and many more are also represented in this segment. Most manufacturers offer a wide range of simple and inexpensive navigation devices to more expensive, highly professional models.

What are the decisive purchase criteria?

Before you make your purchase decision, it makes sense to examine the most important criteria again. This is the only way to find out whether the selected GPS device really complies with your wishes and requirements. Pay particular attention to these points:

  1. Is the device of high quality and waterproof?
  2. Is the battery or battery life sufficient for your tours?
  3. Does the device have a high-contrast touchscreen display that can be easily operated even when wearing gloves?
  4. Does it have all the functions you want, such as recording, navigation, creating personal profiles, route suggestions, POI (Points of Interest) etc.?
  5. Can the internal memory be expanded with a microSD card?
  6. Is extensive map material included and what about future updates?
  7. Is a mount included?

If you have taken all of these purchase criteria into account, then a limited selection of devices should quickly emerge from which you then only have to choose the final favorite. Of course, the price-performance ratio should also play a role in this process. 

Which bike computer accessories are recommended?

Under certain circumstances, it may make sense to think about buying bike computer accessories. Are you planning longer bike tours, for example, where you would like to use your navigation device more intensively? Then it could be a smart investment to buy an additional battery so that you don’t run out of juice on the go.

As far as the mounts are concerned, it may be worth replacing the supplied parts with something of a higher quality. Whether a handlebar mount or an adjustable stem mount, various manufacturers offer convenient and robust alternatives. If you want to safely transport your device beyond bike tours, you should consider buying a protective bag.

How to maintain a bike computer?

So that you can enjoy your bike computer for as long as possible, you should value careful and regular maintenance. A microfiber cloth is recommended for cleaning the touchscreen display, which can be used to remove light dirt and fingerprints in no time. An eyeglass cleaning cloth is also suitable for this purpose. In any case, proceed as carefully as possible so that the screen is not scratched when cleaning.

To clean the mount of the navigation device thoroughly, you can also moisten the cloth a little. In order to achieve the best results, we recommend that you remove the bike computer beforehand so that you can get to every corner better. If the device is not being used, ideally store it in a protective cover so that it does not become dusty. You may also want to consider purchasing a display film to protect the sensitive screen and increase its lifespan.

Bike Computer Alternatives: Which Bike App is the best?

As an alternative to a real bike computer, you may have thought about simply downloading a bicycle navigation app to your smartphone and using it. This is a practice that cannot be generally discouraged. Especially as an occasional user, this variant can make sense for you.

However, you should keep in mind that a conventional bicycle navigation system will generally be significantly more reliable than the available apps. Especially in wind and weather, it is also better to have a robust device attached to the handlebar and not a sensitive smartphone that can quickly be damaged by the rain.
