Best Overall Bike Computer

Garmin Edge 810

Editors' Choice Award

Price:   $400 online
Compare at 3 sellers

Read the review

The Garmin Edge 810 is the winner of our Editors' Choice Award. It is a GPS enabled, ANT+ compatible bike computer with a dizzying array of features and a top-notch user interface. We love the turn-by-turn mapping and the ability to load detailed maps onto the device; this feature really sets the Edge 810 apart from the competition. Other computers we tested are GPS enabled and capable of showing your position on a map, but without the ability to load detailed maps like on the Edge 810, the usefulness is limited. The 810's screen is larger than any other in our test group, which makes viewing data easy, even when you are cross-eyed at the end of hard interval. A touch screen makes scrolling through pages and data fields easy, even with gloves on. The ability to pair with almost any ANT+ sensor and Blue Tooth 2.0 for smartphone integration, and now the addition of Strava Live, is the icing on the cake. The Edge 810 is versatile, and can grow with you as you acquire more accessories and bikes.

Best Bang for the Buck

Read the review

Our Best Buy Award goes to the Lezyne Super GPS. While it is far from the cheapest bicycle computer we tested, it offers the most features per dollar and bang for the buck. Lezyne is new to the cycling computer market, but this company has made a big splash in the market with a new line of computers. The Super GPS is their top-end computer and offers connectivity for both Bluetooth Smart and ANT+ sensors. It also communicates with your smart phone and can give you call, text, and email notifications like the Garmin Edge 520. It does not have maps, but for $149 there is nothing else on the market that offers the level of functionality and versatility of the Lezyne Super GPS.

Best Buy for the Casual Cyclist

Cateye Strada Slim

Best Buy Award

Price:   Varies from $45 - $70 online
Compare at 4 sellers

Read the review

While the Lezyne Super GPS takes our Best Buy Award, we recognize that $149 is not a small investment. In addition, many cyclists have no desire to post their rides on social media or compete for KOMs on Strava. Most of us don't work with a coach, and we may not need to track years' worth of ride data for analysis. Basically, you just like to ride! The goal of data collection for you is to satisfy your own curiosity, and challenge yourself to go a bit further on the next ride. If this describes you, then take a look at the Cateye Strada Slim, winner of our Best Buy Award for the Casual Cyclist. It is a simple wireless computer that tracks speed, distance, and time. No GPS, data downloads, or firmware updates. It turns on and off automatically when movement is detected, so all you need to do is get out and ride.

Top Pick for Strava Addicts and Racing

Garmin Edge 520

Top Pick Award

Price:   $300 online
Compare at 4 sellers

Read the review

The Garmin Edge 520 is the newest addition to the Edge family of cycling computers. Garmin eschewed the recent touch screen trend, moving back to the tactile button interface that the original Garmin Edge 500 employed. We love touch screens, but external buttons can be nearly as effective with well thought out functions and positioning. With a new screen layout and menu functions, the 520 takes a bit of familiarization. Once you get the hang of it, we think that you will agree when we say that Garmin nailed it with this computer. This unit has lots of new features, including Strava Live and a host of new metrics such as Estimated VO2 Max, Recovery Advisor, and FTP Tracking and Testing. While you do not get turn-by-turn mapping, the Edge has the memory capacity to load detailed maps of your primary riding area, allowing you to zoom in and see your position and surrounding streets. The Edge 520 also contains Bluetooth Smart, allowing you to pair the unit to your smart phone to get call, text, and email alerts on the screen while riding. If you are a dedicated athlete or weekend warrior who takes your training and KOM hunting seriously, this is the computer for you. It is the compact, sleek, fine-tuned training tool you have been waiting for to replace or upgrade your Edge 500.

Analysis and Test Results

Cycling has diverged into a multitude of subset groups, and now bike manufacturers produce models for nearly every type of user. People get into the sport for many reasons: fitness, competition, transportation, fun. Whatever level you pursue in your cycling endeavors, being able to quantify the ride can bring satisfaction to your efforts.

Cyclists come in many different varieties, from the seasoned pro to the weekend warrior, and everything in between. Some of us enjoy the dirt, some the pavement, and many participate in many different cycling disciplines. Regardless of the type of bike you choose, one thing we all want to know is "How far did I ride?" Cycling computers give us a means to quantify our efforts in terms of distance, time, speed, elevation gain, watts, and kilojoules as well of a long list of other metrics we never knew we cared about.

What does this mean to you?… Do you even need a cycling computer?

The short answer is no. It is certainly possible to enjoy riding a bike without tracking any data, and sometimes it is nice to skip the computer even for the die-hard data junkie. However most of us cycle to improve our fitness, or shed a few accumulated winter pounds, and even if that is not why we ride bikes it is certainly a nice side effect of having fun on the bike. A cycling computer can give you quantifiable information to help you reach your fitness goals.

Cyclocross racing, the perfect bike computer testing ground.

Once the tool of only the Pro cyclist, the bike computer has come a long way in the last 30 years. The Avocet 30 was released in 1985, and quickly found its way onto the bars of many professional cyclists' bikes. Avocet provided a way for cyclists to accurately track speed, distance, and time of a ride. Tracking training data was of particular importance to the professional cyclist, but cycling computers have found their way onto a much broader range of users' rides. If you just started cycling, you will quickly notice that nearly every rider you see will have some sort of cycling computer on his or her handlebars.

Types of Cycling Computers

If you do a Google search for bicycle computer, you will get pages of results from a range of manufacturers. There are many different types of bicycle computers, but we have broken them down into two primary types: GPS enabled units, and non-GPS enabled.

Non-GPS Enabled Bicycle Computers

Click to enlarge
The Cateye Strada Slim is a wireless cycling computer that does not use GPS or ANT+. It can be mounted on the stem or handlebars using the included rubber straps.
Bicycle computers that are not GPS enabled measure speed and distance using sensors that track wheel rotations. Some are also capable of tracking cadence with additional sensors. Most also track time, and may track temperature, and give you averages of some collected data. Some models use wired sensors, and others use wireless sensors. In general, these computers are cheaper than GPS enabled computers, and offer less detailed data tracking. Most are also incapable of downloading data to your personal computer or a third party data tracking system such as Strava or Training Peaks. They will, however, keep track of your overall millage over time, but this data will often be lost when the battery needs to be replaced.

GPS Enabled Computers

Click to enlarge
Four heavy-hitting GPS bike computers that we compared side-by-side in our detailed review: Garmin Edge 810, Edge 510, Edge 520, and the Lezyne Super GPS.
There are a number of different GPS enabled bicycle computers on the market. These computers use GPS signals to track speed, distance, time, elevation gain and loss, as well as a host of other metrics using both proprietary and third party sensors. Most offer the ability to save workouts or rides, and allow you to download the data to your PC or directly to third party data tracking systems such as Strava, Training Peaks, and Garmin Connect. All of the GPS Enabled computers we tested use the ANT+ wireless protocol, making them compatible with any accessory that uses ANT+, such as power meters, speed sensors, and cadence sensors.

Why Not Just Use My iPhone?

So, you have likely seen cyclists with iPhones or other Smartphones attached to their handlebars. There are many free applications that allow you to use your iPhone or Smartphone as a cycling computer, including Strava and Wahoo Fitness. So the main reason to use your Smartphone is simple: you already have one! Unfortunately that is, in our opinion, about the only reason to consider this as an option.

First of all, in order to use your phone you will need to purchase some sort of case and mount to put it in a usable position on your handlebars. These cases can be expensive, and are not a minor investment.

Second, though your iPhone has GPS capabilities, is not a dedicated GPS device. Cell phones typically use what is called A-GPS, which stands for Assisted GPS. They use both cell triangulation and GPS signals to pinpoint location. In general, they can be faster at pinpointing than a GPS alone, such as a Garmin, because they use both systems. However, if you have no cell service or WiFi, while your phone will still use GPS to track position, you may not have a detailed map, because detailed maps are not stored on phones. Phones use cellular data or WiFi data to populate the information on the map. You can purchase maps that are downloadable to your phone, and then it would function essentially the same as a Garmin GPS with maps, such as the Edge 810 or 520. However, after purchasing a mount, a case, and downloadable maps, you probably would save money by just buying a separate bike computer.

Another issue (and the biggest one in our view) is battery life. We have drained the battery on an iPhone 5s on a 2hr ride using the Strava application. If you are just starting out as a cyclist and think that 2 hours seems like a long time, just wait. Before you know it, you will be hammering out century rides with your local club, and your phone will be dead long before the end of your ride. Accessory compatibility is also an issue you will likely run into as well. Most phones are not compatible with ANT+ sensors. Most of the heart rate, cadence, and speed sensors on the market use the ANT+ protocol and will not work with the majority of smart phones (unless you purchase an ANT+ receiver for your phone.) More manufacturers are getting in the game with Bluetooth 4.0 accessories, but ANT+ is still the gorilla in the room when it comes to third party sensor standards.

We recommend you purchase a stand alone cycling computer for tracking your data. Yes, we ride with our cell phones, but they stay in the jersey pocket for communication purposes in case of an emergency. A dedicated computer sits on the handlebars in easy reach and view throughout the entirety of our rides.

Criteria For Evaluation

Ease of Use and Interface

Using a cycling computer when riding and training adds another step to your ride preparation, but should not be a hindrance to you enjoying your ride. This is our most heavily weighted rating metric because it is the one that will affect you the most. The two highest scoring products are the Garmin Edge 810, winner of our Editors' Choice award, and the Garmin Edge 520, winner of our Top Pick Award. We took into account a multitude of factors including: start-up time, charging and battery life, touch screen or button interface, screen type, and ease of uploading workouts to your personal computer. Here is a breakdown of how all of our contenders fare below.

Click to enlarge
The Garmin Edge 520 out for testing on some gravel roads.

Start-up time:
The faster, the better right? We think so. Less time waiting for the computer to start up equals more time to ride. The non-GPS enabled Cateye Strada Slim and Cateye Velo 7 start up automatically when movement is detected. This is a nice feature, nothing worse than realizing you forgot to turn your computer on when you are half way through a ride… kind of makes you feel like it never even happened. The 3 Garmin units in our review, the Edge 810, Edge 520, and the Edge 200 all must be turned on by pressing the power button. Once they are powered on, the user may select from Activity Profiles, and Bikes and the unit needs to acquire satellite signal. Sounds like a lot, but with frequent use this only takes 30 seconds or so. It is worth noting that the, Edge 520 and the Lezyne Super GPS pick up satellites a bit quicker, between 5-10 seconds on average, due to the ability to use both GPS and GLONAS Satellites. The other Garmin units we tested utilize GPS only. In summary, start-up of the GPS enabled computers takes a bit longer than those without GPS, but it is fairly negligible and the wait is worth the benefits.

Charging and Battery Life:
All of the computers we tested utilize some sort of battery for power. The Cateye Strada Slim, Cateye Velo 7, and the Planet Bike Protégé both utilize 2032 disposable coin cell batteries. The Cateye Strada Slim actually employs two, one in the computer head unit and one in the wireless speed sensor. In contrast, the Garmin units, Magellan Cyclo 505, and the Lezyne Super GPS utilize built in rechargeable batteries. Which option is better? Well, we prefer rechargeable batteries for a few reasons. Less waste, and if we kill the battery, a trip to the store to purchase a new battery is not required. That being said, 2032 lithium batteries are not that expensive and can be purchased for less than $1 each online or will run you $2-$3 at most retail stores.

The Cateye Strada Slim, Cateye Velo 7 and the Planet Bike Protégé claim battery life to be 1 year or more. We got 4 months of use out of the Cateye Strada Slim, and about the same out of the Cateye Velo 7, but this was with an average of 10-14 hours a week of ride time, so it is entirely feasible that many users would get a year or more with moderate use.

The Garmin units we tested all utilize rechargeable Lithium Ion batteries and come with wall chargers, but can also be charged via included USB to Micro USB cables that come with the units. Charge times from a complete discharge are around 2 hrs for all of the units. Battery life ranges from 20 hrs for the Edge 510 to 14 hrs for the Edge 200. The Edge 520 is the newest unit in the Garmin line up and uses a mini USB cable rather than the micro USB cable utilized by all previous Garmin models.

The Lezyne Super GPS has an impressive 22 hr run time using a rechargeable Lithium Polymer battery that can be recharged with the included micro USB cable using a computer or USB wall adaptor.

On the other end of the spectrum, the Magellan Cyclo 505 has a relatively short battery life; we were only able to get around 10hrs of use on average from a fully charged battery. We were surprised by the poor battery life from a computer that is clearly aimed more towards the touring crowd than any other user group.

Click to enlarge
The Lezyne Super GPS has only four buttons, two on each side. We find it to be intuitive and easy to use. The primary benefit is its compatibility with both ANT+ and Bluetooth Smart sensors.
By interface we mean the method by which the user interacts with the device. Is it easy to navigate through menus and functions? Are buttons used or a touch screen? Our highest scoring products are the Garmin Edge 810 and the Garmin Edge 520. The 810 utilizes a combination of buttons and a touch screen. Buttons are used for the most frequently used functions: power on and off, start/stop workout, and lap. The touch screen is used to navigate between pages of preselected data points during a workout, and for all set-up, menu functions, and navigation. The touch screen technology Garmin employs is not perfect, but it is quite functional with a bit of practice, and it even works with gloves on. For more details on the touch screen see our full product reviews of the Garmin 810 and 510. In contrast, the Garmin 520 uses only buttons, but the quantity, function, and layout of the buttons is excellent, making navigation simple and intuitive. External buttons, if executed well, can be as or more effective than a touch screen. The Lezyne Super GPS also has a button only interface, but the buttons are a bit less user friendly than the competing Garmin Edge 520. The Cateye Velo 7 and the Cateye Strada Slim both require a paperclip or other implement to press small reset/program buttons located on the back of computer to access set-up menus, making them the least user friendly models we tested.

All of the computers we tested require some set-up. Set-up should factor into your purchase decision, but keep in mind that more complex computers require a bit more time investment up front, but for the most part this is a one time or occasional hassle. How difficult a computer is to set-up is largely dependent on how many features and accessories the unit has or is capable of utilizing. So you may notice that the units that score high in our features metric conversely score a bit lower on set-up. Additional factors to consider include whether the computer is wired or wireless. The Garmin Edge 200 is our highest scoring product in this category. Set-up is as simple as attaching the ¼ turn mounts to the handlebars and turning the unit on. The more feature rich Garmin 510, 520, and 810 score slightly lower due to the increased time required to configure additional features and to pair compatible accessories. In contrast, the Cateye Velo 7 and the Planet Bike Protégé 9.0 received lower scores due to the hassle of routing and securing wires and issues with set up screen navigation. The Cateye Velo 7 and the Planet Bike Protégé 9.0 also both require the use of multiple zip ties. For detailed information on product set-up, see our in depth individual product reviews.

The Lezyne Super GPS does not have a color screen, but it packs lots of performance features into a simple package.


Bike computers range from simple to extremely complex. When it comes to features, we focus on features that you can actually use. It should come as no surprise that the Garmin Edge 810, winner of our Editors' Choice Award, is also the most feature rich computer we tested. The Edge 810 is GPS enabled, ANT+ accessory compatible, blue tooth compatible, has a touch screen, and is one of only two computers we tested with turn-by-turn navigation capabilities. The Edge 520 is a close competitors in the features competition with all of the features of the Edge 810, minus the mapping capabilities. The Edge 810 and the is Bluetooth 2.1 enabled and can communicate with your Smartphone via the Garmin Connect Application. The Magellan 505, Garmin Edge 520, and the Lezyne Super GPS are Bluetooth Smart enabled and can receive text, email, and phone call notifications when paired with a compatible IOS or Android device. With Garmin computers, smartphone integration allows unique features such as Live Tracker, which allows people whom you invite to view your ride as it occurs on the Garmin website. This connectivity also allows for instant wireless uploads of ride data to Garmin Connect. These features, and a multitude of others, place the Garmin Edge 810 and the Edge 520 at the top of the food chain when it comes to features. We have a full breakdown of all of the class leading features the Garmin Edge 810 employs in our full product review.

In contrast to the tech heavy, feature laden Garmin, Lezyne, and Magellan units; we tested the Cateye Velo 7, Cateye Strada Slim, and the Planet Bike Protégé. These units offer more basic data collection, without the help of GPS and ANT+ accessory compatibility. Although these units are lower scoring, they still provide reliable data collection for time, distance, and speed.

Social Data Tracking: Strava
Strava is a web-based service that allows users to upload workout and ride data from a host of different devices, including Garmin, Magellan, and Lezyne. Strava also offers free applications for most smart phones, which allow you to use your phone as a ride-tracking device. Strava is equal parts social forum and workout tracking software, with the heart of the experience being competition with other users on specific segment times. Segments are user created and selected portions of a ride, and include anything from a 2hr climb to a 10 second sprint.

Click to enlarge
You can search for popular segments in our area on a smart phone and save them to your Garmin device, Using Garmin Connect.

The start and end of a segment are GPS coordinates, and your time on a given segment is calculated by Strava using the GPS ride files you upload to the site. In July of 2015 Strava began offering a new service called Strava Live to Premium Members (Premium Membership costs $6 per month or $59 for a year). Strava Live was released in conjunction with the new Garmin Edge 520, and is also now available on the 820, and 1000 with a free firmware update from Garmin. The Lezyne Super GPS is also compatible. Strava Live loads segments of your choice, or ones selected for you by Strava, onto your Garmin device, via Garmin Connect. So in order to utilize Strava Live, you need 3 things: a Strava Premium account, a compatible device, and a Garmin Connect account. The chosen segments can be uploaded to the device by connecting to Garmin Connect via your smart phone, or by a USB cable connection to your computer. If you are using the Lezyne Super GPS the segments can be individually selected and loaded via the Lezyne Ally smart phone application.
Click to enlarge
The segments above have been starred so they will be stored on a compatible Garmin Device when it is synced with Garmin Connect and used for Strava Live.

Once the segments are loaded to your device, you will also have information about each segment including the KOM (fastest time), as well as your PR (personal record time). While out riding, as you approach the beginning of a segment, your device will prompt you with distance alerts such as (500ft) to the start of the segment.
Click to enlarge
Strava Live will let you know how far until the start of a segment, so you do not waste any energy in the pursuit of your PR or KOM. Here you can see Strava Live in use on the Garmin Edge 520.
Once you cross the starting point the device will display a large "GO!" on the screen. The screen will then display your PR time for the segment as well as "distance to go", and either "time ahead" or "time behind". At the conclusion of the segment you will be notified if you achieved a new KOM or PR for the segment. While you in no way need Strava Live in order to enjoy a ride or get a good workout in, it can be a great training tool. It might just give you that extra needed motivation to push a bit harder and achieve your goal. We also acknowledge that it can be annoying, particularly if you are out doing a recovery ride and the goal is actually to ride slow. The good news is you can easily disable Strava Live in settings, even while you are riding. Some people will love it some will not, but it is certainly a nice option to have if you own a Garmin Edge 810, 520 or Lezyne Super GPS.

Water Resistance

Even if you do not intend to ever venture out on your bike in the rain, sooner or later you will find yourself caught in an unexpected shower. For those of you on a serious training program, you will almost certainly be training or racing in inclement weather at some point. So what is going to happen to your expensive cycling computer when it gets wet? Well, hopefully nothing. We feel that water resistance is a critical feature of a quality bike computer.

Click to enlarge
Garmin Edge 810 out for some early spring testing.

All of the Garmin Edge cycling computers, the Lezyne Super GPS, and the Magellan Cyclo 505 are rated IPX7 for water resistance, making them our highest rated products in this category. The IPX rating system is a European standard that assigns rating protection numbers for electronics. IPX7 rated devices can withstand 30 minutes of accidental submersion in 1 meter of water. We had no issues with water damage on any Garmin units we tested, despite riding in the rain and snow, and some less than accidental immersions in the name of science. All of the other cycling computers we tested claim to be "water resistant", but do not conform to any universal standard. Lower scoring products such as the Cateye Velo 7 and the Planet Bike Protégé 9.0 allowed some water to permeate the battery compartment during testing.


Many of us at OutdoorGearLab participate in multiple different styles of cycling. A road ride today can easily lead into a long backcountry epic on the mountain bike tomorrow. So, versatility is important to us and likely to you as well. Ideally we want to purchase one cycling computer that can be used on all of our bikes.

The Garmin Edge 510 is a versatile cycling computer, at home on any type of bike.

The Garmin Edge 810 receives high marks here, followed closely by the Edge 520. The Edge 810 takes the top spot due to it's unique mapping functions, making it ideal for riders embarking on a long touring ride, or adventure on unknown roads. The Garmin Edge 520 slides in a close second to the Edge 810, the 520 does not have routable maps, but it is possible to download detailed maps to the unit and zoom in to see your exact location on a map. All of the Garmin models are easily swapped between multiple bikes with the excellent Garmin ¼ turn mounts, and they all can be programmed with unique profiles for different bikes. The Lezyne Super GPS is also a very versatile computer, with a compact profile and easy to use "x-lock" mounts, it can be swapped between bikes and used to track data for any type of riding. Its versatility is only hampered by the lack of mapping functions.

The Edge 810, and 520 also have Activity Profiles allowing you to customize data fields, pages, and alerts for different types of rides, such as training vs. racing. All of the Garmin computers in our test group, with the exception of the Edge 200 are also compatible with a multitude of ANT+ accessories that allows you to have speed and cadence sensors mounted on multiple bikes, and only move the computer head unit between bikes. These features make using the same device for different bikes and types of riding much easier. In contrast, the Cateye Velo 7 has a wired speed sensor, making it difficult to move between bikes.

The Lezyne Super GPS and the Magellan Cyclo 505 also deserve a nod for their compatibility with both ANT+ and Bluetooth Smart Sensors. This allows you to pick and choose sensors from a variety of manufacturers.

Versatility is important; it not only makes life easier, but can also save you some money. For details on how each product stacks up see our individual product reviews.
