How to Choose the Best Bike Computer For You

There are many reasons why you might want to upgrade your bike rides with a bike computer.

If you are looking to track your routes, log your cycling data, or monitor your speed, heart rate, and cadence, a bike computer is the best way to do this.

Now, instead of needing to download multiple mobile apps or purchasing multiple devices to attach to your bike; you can do it all with a bike computer.

Whether you’re a more casual rider, a mountain biker, or a competitive cyclist, you will find benefits in using a bike computer. Many are reasonably priced, and will conveniently attach to any bike you own.

Also, many offer ways to connect to tracking apps on your phone so you can network with your friends and family. These features allow you to transform your basic rides into interconnected tracking experiences which you can share with the rest of the world.

Different Types of Bike Computers

There are many different kinds of bike computers available, and their differences can seem very complex. Do not feel overwhelmed however, most provide the same fundamental features, with some slight variations between them.

There are more advanced types, and there are very simple types for less serious riders. In short, the two basic types of bike computers are GPS-enabled bike computers and non-GPS bike computers.

Though as technology gets cheaper, most bike computers now have GPS embedded within them.

Non-GPS Bike Computers

These devices are most beneficial for measuring heart rate, cadence, and body and outside temperatures.

Many of these bike computers will also measure the speed and distances of your rides, and then provide you with maximums and averages for all data collected. These bike computers log data typically via wired sensors.

GPS-Enabled Bike Computers

These computers typically provide more accurate measurements of speed and distances because they use GPS signals in addition to third party sensors instead of wired sensors. The data collected is usually far more detailed than non-GPS bike computers.

Also, these devices offer many ways to connect to your phone or PC and download the information about your rides. They tend to be more expensive than computers that do not have this capability.

In addition to these variations, bike computers can differ in size, color, shape, weight, and basic functionality.

Ease of Use

Incorporating the use of a bike computer adds a new dimension to your bike rides. Once configured they can enhance your rides entirely with quite a bit of data. It is important to not become overwhelmed with the setup or the complex nature of their functionality.

Even though all of the bike computers reviewed in this list can be learned and utilized easily in order to improve the overall quality of your rides, Garmin products are well known for their easy-to-use interfaces.

The Garmin Edge 25 Cycling GPS and the Garmin Edge 810 GPS Bike Computer are the devices you want to look for if ease of use is a high priority.

By interface, we mean how easy these devices are to navigate and get to the features you need. The process of learning how to best use your bike computer can be complicated.

Screen Size

Many bike computers available now are a pretty close in size, but some are notably small like the Garmin Edge 25, and others are inconveniently large. While being larger makes it easier to read the screen, it might get in the way on your handlebars.


Does the device have a color screen, or is it black-and-white? Some devices still use black-and-white screens, which can make them harder to see as you are riding.

Navigating the menu systems on some bike computers can be daunting and difficult to learn. Personally I prefer ease of use to having features I never use.

If you’re worried about screen visibility in the dark, then you should absolutely select a model with a backlight feature. Sure, you could shine your helmet light on the screen, or even your smartphone flashlight, but that’s nowhere near as effective as a backlight.

Also, think about the data screens. Certain devices have it set up with data restricted to just one screen, while others allow you to scroll through various screens by pushing a button. You can also customize the screens on some, while others only have one option.

Magnetic models are going to have a fixed font size. If that size works for your eyesight, great! But if not, then you’re kind of out of luck. GPS models usually allow you to change the font size.

If the font isn’t big enough for you to read comfortably, that’s not a good sign. Then when you add in the road vibration, it’s going to be even more difficult.

Start Time (for GPS bike computers)

Another aspect to consider is the startup time of the GPS. You do not want to be waiting around, ready to ride, and your computer taking forever to acquire satellites.

Of course, faster is better. The Garmin products reviewed in this article take only 30 seconds or so to boot up after you press the power button.

By the time you lace your shoes, or get your water bottle in place the computer should be ready to go. Once powered on, these devices operate very reliably and can be used while in a forest, mountain biking or urban areas.

Battery Life

Battery life is another essential element to consider when selecting a bike computer. You want your charge to last throughout the duration of your ride. The ideal computer will keep a charge that lasts for several rides.

Garmin Edge products, such as the Garmin Edge 810 and the Garmin Edge 25, tend to have the best battery life. If you go on all day rides this will be more of consideration and you will want to consider these computers first.

Data Transfer and Smart Phone Integration

Best Bike ComputersOne primary benefit of modern bike computer technology is the ability to transfer data about your routes and rides to your computer and data tracking websites like the Garmin Connect website.

If you are serious about collecting and logging information such as the distance you traveled, your heart rate, your speed, etc., you want to ensure you select a bike computer with data logging/transfer capabilities.

Data transfer can be done in two ways. You can connect the a Micro USB cable to your computer, or you can use a smart phone application that uses Bluetooth.

Many of the computers reviewed in this article can be set to “auto upload” mode where your data will automatically be transferred to a tracking database on your mobile device.

This feature eliminates the need to manually upload information yourself and makes for trouble free operation.

Garmin devices conveniently connect to an app named Garmin Connect, which must be navigated carefully, but allows you to log, track, and organize your ride data. Lezyne devices connect to a similar app named Lezyne Ally.

There are also other individualized applications you may find for other bike computers, but these two are the most popular. With the advancement of technology, more and more bike computers are shifting away from the Micro USB cable, so it is best to get a computer with Bluetooth compatibility.


Regardless of which bike computer you purchase, you will need to configure it. Setup is another important factor you need to consider when selecting one.

Do not be deterred by more complicated setups, its a one time thing. Sometimes bike computers with more features and accessories just take more time to configure.

Nearly all of the bike computers come with detailed manuals in the box or websites that have online manuals and/or videos showing you the configuration steps.


Before selecting a device, you will want to figure out which features matter most to you. Bike computers vary greatly in complexity, and come with a large variety of features.

Researching these features before deciding on a device can save you money, many of the more expensive computers may include features and functionality you don’t want or need.

Some Key Features to Consider:

  • Bluetooth compatibility
  • ANT+ compatibility
  • Stress score
  • Ability to communicate with smart phone
  • Live Tracker
  • Method of data collection
  • Mapping and route options
  • Turn-by-turn navigation capability

The Garmin Edge 810 is the most feature-rich bike computer available today. If you are looking for a bike computer with the most capabilities, this is the device for you.

It will require a longer setup and take more time to master, but it will provide you the most options for your rides.

Garmin, Magellan and Lezyne computers offer many different features, and are all fairly similar with only a few minor differences in functionality.

Other brands may offer a few of the features, but will likely not include all of them. Nearly all bike computers provide basic features, such as data collection of heart rate, speed, and distance.

Water Resistance

Water resistance is another factor to consider depending on how you ride. If you are into mountain biking you will likely get mud and water on your bike computer.

Even if you are not planning on riding during rainy weather, you’re bound to find yourself caught in a rainstorm eventually.

You will not want your bike computer to get ruined by a little water. Fortunately, nearly all bike computers can handle having water splashed on them without a problem.


Finally, you will want to consider the versatility of the bike computer before purchasing. If you plan to take many different types of rides (e.g. casual night rides, serious mountain rides, muddy bumpy rides), and you use multiple bikes for these rides, you want to ensure you can easily transfer the device between bikes.

If this describes you, make sure you can easily transfer the computer and you can buy extra mounts and sensors. Most Garmin products fit this criteria, and are easily transferable between bikes.

You will also want to be able to collect data for multiple types of rides in different environments.One you main considerations if you frequently ride on the roads you will probably want a bike computer with mapping capability and even better, turn by turn navigation.

Its usually a good idea to buy a bike computer with more functionally than you think you will need. Once you start using one you will most likely want to use it for tracking more and more things.

Type of Riding

What kind of rider are you?

This is a question to be seriously taken into consideration when selecting the best bike computer for you.

Casual Riders: These types of cyclists only want the simple stats like distance, speed, and time they’ve been going.

Enthusiast Riders: If you’re an enthusiast, a regular commuter, a touring cyclist, you may want a few more details than casual riders. You may want to know how long of a distance your trip is, the average speed you travel at, the max speed you reach, and the total odometer.

Competitive Riders: If you classify yourself as a competitive cyclist, you’re probably going to want to know just about everything you can about your performance. Cadence, heart rate, elevation gained, power output, and more should be included.

FAQs About Bike Computers

Q: Which type of bike computer is more accurate?

A: Generally speaking, a GPS bike computer is going to be the more accurate/reliable option in comparison to your smartphone with the app of your choice. If you’re set on a magnetic model, you aren’t out of luck. Some can come extremely close to GPS models if the code for your tire size is properly entered into your device.

Q: If I lost the wheel magnet to my magnetic bike computer, can I find another one?

A: Absolutely! You can typically find replacement magnets at your local bike shop, or outdoors stores.

Q: What should I do if my computer isn’t working?

A: You may be tempted to immediately take it in to a bike shop to have them look at it. Before you go, however, make sure to do some troubleshooting to rule out these common possibilities:

Sensor Position: It’s relatively easy to bump the wheel sensor out of its proper position. First, take a look at the alignment and gap between the wheel sensor and the spoke magnet. Of course, if you don’t have a magnetic bike computer then this wouldn’t apply.

Battery: You’ll find that in magnetic wired units, they’ll have a battery in the display, and in magnetic wireless units, one in the wheel fork transmitter. If you’ve had yours for at least two years, you’ll want to replace the battery.

Mount Connection: Check to ensure the display unit is properly connected to the mount. If you’re unsure, remove it, then click it back on again.

Wire Connection: Of course, this will only apply to wired models. Occasionally, the wire will come loose from the mount, or get worn down rubbing against the frame. Make sure the wire is in good condition, and if not, you may have to replace your model.

Q: If the battery dies, is my ride data lost?

A: Nope! You can simply recharge, and even replace batteries without losing your data.

Q: Can’t I just use my smartphone?

A: Sure, you can. Just keep in mind that there are some downsides. First, cycling computers are much more accurate. They’re also specifically designed to work with your bike, and come pre-loaded with tons of programs and displays exclusively for that purpose. You can also customize them more, so you can select the info that you want to display.

Perhaps the biggest upside to opting for a bike computer over a smartphone, is the ability to hold up to the elements. Smartphones are notorious for getting harmed in harsh weather. Bike computers have a sturdy chassis typically, so this won’t be an issue for them. They’re also made to be able to hold up better if you do by chance, crash.

Tips For Picking Out a Bike Computer

Tip #1: Watch your cadence

Having a cadence sensor will allow you to break your barriers and to test out other cadence ranges to determine what works best for your training purposes. For example, you may find your current cadence has built up your leg strength well. Experimenting with a different cadence range may  improve neuromuscular coordination. Depending on what you’re aiming for, you’ll want to achieve the proper range to get the most out of your training session.

Tip #2: Find new routes

Not only for training purposes, but for also avoiding burn-out, you should try to find fresh routes every now-and-then. There are some computers which have the feature of letting you plan out a path anywhere you’d like, while providing you with some of the most well-known and even “secret” routes.

I hope this guide was helpful for finding the best bike computer to fit your needs. If you want to comment or recommend one I didn’t include, please use my contact form to get in touch.

Have fun and be safe out there!
