The best cycling computers are a far cry from the original ‘Cyclometer’ invented by Curtis H Veeder, an analogue device that counted how many times a wheel rotated, and converted that into distance using a formula.
Nowadays, the best bike computers are wireless, compact handlebar-mounted devices that feature a GPS chip, Bluetooth, ANT+, WiFi and provide a host of information such as maps, weather, speed, distance and time. They connect to the best power meters to provide instant power readings, training stress score, left-right balance and more. Many can connect to your smartphone, as well as Strava segments and komoot maps, and most will even control the best turbo trainers in place of software such as Zwift.
When you're shopping for a new cycling computer, it can be challenging to navigate the vast spec sheets that come along with even the most basic units, so in the list below we’ll help you to wade through the tech jargon and help to find and buy the best cycling computer for you.
If you're looking for advice on what to look for in a cycling computer, we've put that at the bottom of this page, the following link will take you there.
Best cycling computers
Packed full of navigational and training features, the Edge 1030 Plus is supremely easy to use
Price: $600 / £500 / AU$750 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: Garmin Cycle Maps | Battery life: 20 hours | Colour screen: Yes | Screen size: 3.5in / 89mm
The 1030 Plus represents Garmin's flagship model and the gold standard when it comes to bike computers and navigation. It's the largest in the brand's cycling range with exterior dimensions of 4.5in tall, 2.3in wide, and 0.8in thick. Utilising the brand's cycle maps, the 1030 guides you via Garmin's Trendline Popularity Routing, drawing from billions of miles of Garmin Connect ride data to guide you towards more bike-friendly routes.
The Garmin 1030 Plus has all the features you'd expect from a top-end cycling computer. Navigation features detailed maps and the touch screen makes it easy to move around the map mid-ride if you need to.
Record your rides with power and heart rate, and Garmin will give a detailed analysis of every ride. The analysis offered is far beyond what anyone else is offering. It will give a window into every ride to tell you when your training is effective, and how, as well as when it's time to take a break.
Being that this computer sits at the top of Garmin’s range, it’s no surprise it’s got every training bell and whistle the brand has to throw into a single unit and supports both ANT+ and Bluetooth sensors including power meters.
The combination of price and performance will make for a popular choice
Price: $299 / £259 / AU$499 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: Garmin Cycle Maps, Trail Forks | Battery life: 20 hours | Colour screen: Yes | Screen size: 2.6in / 66mm diagonal
The follow up to the uber-successful Edge 520, the brand new Garmin Edge 530 expands on the rich training suite and adds a faster processor to massively improve mapping.
Despite many reports of setup headaches - something we also experienced - once out of the way, the long list of features makes for a great device that is fast, clear, and a positive addition to your ride. The lack of touch screen makes for labour-intensive map browsing, although that's not something you're likely to do often.
If you're a touchscreen advocate, opt for the Edge 830, but if you prefer the tactile feel of button pushes, the 530 is equally feature-rich and refined.
With both Garmin Cycle Maps and Trail Forks pre-installed on the Edge 530, whether on the road or trail, it can help you find your way. With a battery life of 20 hours - 40 in battery saver mode - it’s also one of the longest-lasting computers on the market, and that's before you add the Garmin Charge optional battery pack.
The Edge 530 also gets access to the Garmin Connect store, meaning you can add apps like Accuweather, Yelp, and Komoot among others, download data fields, and the computer can also talk to Garmin’s Varia Radar lights.
A full featured computer that puts a premium on user interface, now with a colour screen
Price: $380 / £300 / AU$600 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: OpenStreet Map | Battery life: 17 hours | Colour screen: Yes | Screen size: 2.7in / 68.58mm diagonal
The Roam builds on the foundation laid by the original Wahoo Elemnt GPS computer including a wide feature set that covers the basics and does it exceptionally well. While the navigation may not quite match the similarly priced Garmin 830, how often do you actually use that function of your cycling computer?
If the answer is all the time, the Wahoo may leave you wanting more, but for the rest of us, who may use navigation every once in a while at home, or when you might be travelling, the Roam’s breadth of data fields, seamless smartphone integration and overall ease of use are in a league above the rest.
For the price, the on-device navigation could certainly improve. However, that probably means adding a touchscreen which may increase its price point even further.
With all of that said, the improved mapping and use of colour on the maps show a marked improvement over its predecessor. Add to this the intuitive ease of use and functionality and it's an incredibly difficult device not to recommend.
A lot for your money but not the most intuitive option out there
Price: $TBC / £109.99 / AU$TBC | Connectivity: ANT+, Bluetooth | Companion app: Yes | Navigation: Breadcrumb | Battery life: 35 hours | Colour screen: No | Screen size: 2.3in / 58mm diagonal
In our experience, Bryton bike computers come with a bit of a learning curve and aren’t the most user-friendly units on the market, but after a bit of learning, what they do offer is serious bang for your buck and are currently used by Israel Start-Up Nation in the WorldTour.
With a companion app, you can create yourself a route and sync it to your unit for breadcrumb style routing. There's support for ANT+ and Bluetooth sensors, 77 functions and a claimed 35-hours of battery life.
The Rider 420 also allows for workouts to be exported from TrainingPeaks directly through the device, auto-sync to third-party training software, and allows for the screens and data fields to be set up through the companion smartphone app.
If you're someone who follows routes often, the Rider 420 might not be the best for you, but if you're after big function with a small price, look no further.
Tthe best screen and navigational metrics in the game
Price: Starting from US$399 / £300 / €335 | Connectivity: ANT+, Bluetooth, WiFi, cellular | Companion app: No | Navigation: OpenStreet Map | Battery life: 12-hours | Colour screen: Yes | Screen size: 3.2in / 82mm diagonal
With a 4.5-star rating in our Hammerhead Karoo review, it's inevitable that the second generation of this GPS computer made it onto this list. It's smaller, lighter and even more capable than its predecessor, and brings a premium experience to a broader audience. If you're after a more holistic cycling computer experience, look no further.
The Karoo 2 boasts a high-definition 3.2in scratch-resistant screen made from DragonTrail glass, making it super resilient even in wet weather. It's 40 per cent smaller and 33 per cent lighter than the original model, tipping the scales at just 125g.
The Karoo 2 is claimed to have 12 hours of battery life, providing advanced mapping and GPS capabilities, and intuitive functionality for the duration of most rides. The unit is mounted with the brand's own system. The linear-lock design ensures it stays planted and balanced while in use, and is also compatible with time trial and tri cockpits.
Running on a customised Android 8 OS, the Karoo 2 is fully compatible with third party apps like Strava and Training Peaks, and while you'll need to create an account to use it, you'll gain access to further customising and route-building options.
One of the most powerful power training tools, especially when paired with a Pioneer power meter
Price: $359 / £169 / AU$299 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: OpenStreet Map | Battery life: 12 hours | Colour screen: Yes | Screen size: 2.2in / 56mm
When Pioneer entered the cycling market, the brand didn't gain its footing until the second iteration of head units and power meters. The power meter offered an overwhelming amount of data, including directional force measurements, and the SGX-500 head unit was feature rich but made you want to pull your hair out.
With its latest GPS cycling computer, the Pioneer SGX-CA600 hasn’t fixed its naming protocol, but the head unit itself is vastly improved.
First and foremost, Pioneer has fixed the rage-inducing touch screen and now allows for setup through your smartphone — double win. The head unit also features a bright, full-colour 2.2in / 56mm display, preloaded OpenStreet base map for navigation and turn by turn directions, ANT+, Bluetooth, and WiFi connectivity allowing it to talk to sensors and your smartphone. The new Pioneer head unit also plays nice with Strava, Training Peaks and Today's Plan, as well as electronic drive trains.
When used with a Pioneer power meter, the SGX-CA600 unlocks a host of in-depth pedalling metrics and information to help you improve your technique and efficiency.
Wahoo ELEMNT Bolt
Fully featured, aero shaped head unit with great battery life that doesn’t cost a limb
Price: $249.99 / £199.99 / AU$399 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: OpenStreet Map | Battery life: 15 hours | Colour screen: No | Screen size: 2.2in / 56mm diagonal
When it was released, the Wahoo ELEMNT Bolt was basically a more compact ‘aero’ version of the brand's first computer. It had all the same features, minus one set of LED’s along the side of the screen and longer battery life — claimed at 15 hours.
Like the Roam, the Bolt relies heavily on the companion app for setup, but it’s a streamlined and intuitive process, and the ease of use is second to none. While it doesn’t get a colour screen, the monochrome version is excellent for data fields, but when it comes to navigation, it’s sometimes challenging to figure out where you’re supposed to go.
Speaking of navigation, the device comes with preloaded global maps optimised for bike-friendly routes and turn by turn navigation.
Like its more expensive cousin, the Bolt features tons of training metrics, support for both ANT+ and Bluetooth, as well as WiFi for speedy uploads to Strava, Training Peaks or wherever else you’d like your rides to be stored.
Feature-laden cycling computer for data obsessed
Price: $249 / £209 / AU$364 | Connectivity: ANT+, Bluetooth | Companion app: Yes | Navigation: OpenStreet Map | Battery life: 12.5 hours | Colour screen: Yes | Screen size: 2.25in / 58mm
Stages Cycling brought affordable, lightweight data harvesting to the people when it launched its range of power meters just a few years back. This was shortly followed by the Stages Dash - a GPS-based cycling computer designed to centralise the data-monitoring experience.
The all-new Stages Dash M50 benefits from the company's new Everbrite high-resolution colour screen which makes monitoring vitals such as HR, power output and distance a rather simple exercise. While the M50 possesses features such as GPS-based speed and distance, ANT+ and Bluetooth connectivity, its biggest draw card is the improved battery life (12.5-hours) and ability to populate up to 12 data fields.
Furthermore, the M50 is pretty adept when it comes to navigation with cycling-specific Open Street Maps that feature bike paths, dirt tracks and potential hazards. The Stages Dash however, is more about training metrics than GPS navigation and in this regard it has everything polished. Not only is the M50 programmed to follow pre-loaded workouts, it can plot metrics such as FTP, IF and TSS to help measure efforts and pacing.
Lezyne Mega C
Colour sceen and feature packed at a good price
Price: $200 / £180 / AU$300 | Connectivity: ANT+, Bluetooth | Companion app: Yes | Navigation: Breadcrumb, Basemap through the app | Battery life: 32 hours | Colour screen: Yes | Screen size: 2.2in / 56mm
Best known for flashy pumps and drool-worthy tools, Lezyne dipped its toe into the GPS cycling computer market in 2016, and its line of Super GPS computers have found a good balance between functionality and price point.
Utilising a non-touch colour screen, the Mega C boasts a claimed battery life of 32-hours, edging in just above the Bryton Aero 60. The computer also supports ANT+ sensors including power meters and can store up to 800 hours of ride data. The companion app facilitates quick uploads and automatically pushes ride data to Strava, Training Peaks or Today’s Plan.
The little head unit can also help you chase Strava KOM / QOM’s with Live Segments, let you know if it's your kids or work calling you during your ride with on-screen notifications, and offers electronic drivetrain integration through ANT+.
The Mega C does offer turn by turn navigation and even in-activity rerouting, though you’ll need to kick off the route using your mobile phone. In lieu of a pre-installed based map, you’ll also need to sync offline maps from your phone to the computer.
Sigma has take a different route with the Rox 12.0, but the host of mapping features and endless training metrics make it a worthy inclusion
Price: $349 / £279.99 / AU$TBC | Connectivity: WiFi | Companion app: No | Navigation: OpenStreet Map | Battery life: 16 hours | Colour screen: Yes | Screen size: 3in / 76mm
It’s been a while since we’ve seen a high-end cycling computer out of Sigma, and the Rox 12 is a slightly different approach to the GPS head unit. The full-colour touch screen is the closest in ease of use to a smartphone that we’ve come across to date, probably because under the hood it’s an Android device.
While it supports both Bluetooth and ANT+ sensors, interestingly, it does not connect to your phone, instead relying on your home WiFi for uploads, downloads and the like. With no phone connectivity, the only apps the Rox 12 can talk to at the time of writing are Strava, Komoots, Training Peaks and GPSies, as Sigma develops each third-party app for integration directly into the computer.
With Open Street maps preloaded on the device, you can upload routes from Strava, Komoots and GPSies, and you can even search address and points of interest like bike shops and restaurants among other options.
It’s got some pretty nifty power metrics like pedal smoothness and torque effectiveness in addition to all the training data fields you’d expect on a high-end GPS unit. You can also design workouts directly on the head unit too, or sync from Training Peaks.
Despite its size, the Hammerhead Karoo is a quality option that shouldn't be ignored
Price: US$399 / £329 / AU$588 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: OpenStreet Map | Battery life: 15 hours | Colour screen: Yes | Screen size: 3.5in / 89mm diagonal
Make no mistake, the Karoo is a pretty sizeable unit when compared to its rivals but it is sleek-looking nonetheless. The build quality is exceptional and the housing itself is chunky, hardy and designed to take a beating on the road or trail, perhaps that's why Hammerhead doesn't offer a protective silicon case, although we would appreciate the option.
The Hammerhead boasts one of, if not, the best screens on the market. Utilising a 0.9mm-thick sheet of Gorilla Glass, the high-definition 640x480 (229 pixels per inch) touchscreen is super-responsive and one of its biggest drawcards.
The full-colour mapping is superbly detailed and it’s the accuracy of the routing that sets it apart, not to mention the turn-by-turn instructions which display on the bottom of the screen - the company does, after all, pride itself on its navigation proficiency. Routes can be added by loading any of the usual file extensions such as GPX, FIT, TCX, KML, or KMZ.
At 98 x 72 x 28mm the Hammerhead is a fair whack bigger than its rivals but something that didn’t quite bother us. In fact, the bigger screen made monitoring vitals such as power and heart rate less of a strain and more of a pleasure. The Hammerhead Karoo’s mapping and GPS capabilities are unsurpassed, trumping its rivals in terms of accuracy, directional prompting and level of detail. In terms of battery life, Hammerhead claims 15 hours per charge which is on par with segment standards. A clever touch is a battery-saving mode, which allows the Karoo's screen to be turned off while still recording the remainder of the ride.
The training cyclist's choice that foregoes navigation
Price: £679 / $749 / AU$1089 | Connectivity: ANT+, Bluetooth, WiFi | Companion app: Yes | Navigation: No | Battery life: 10-45 hours (3 weeks in standby mode) | Colour screen: No | Screen size: 2.7in / 68mm diagonal
SRM is considered the global authority when it comes to power meters, having forged a reputation in the pro peloton as the go-to data-harvesting tool of choice for the past three decades.
The SRM PC8 may have replaced the PC7 back in 2014 but it's aged impressively well during this time, both from a visual and technological point of view. The most significant hardware step-ups over its forebear comprised GPS, WiFi, Bluetooth 4.0, ANT+ and an accelerometer - nothing particularly revolutionary no, but the PowerControl has never claimed to compete with Garmin and Wahoo or any other GPS computer on the market for that matter.
Screen customisation is a relatively easy exercise allowing users to populate performance metrics and data fields via a smartphone app (the PC8 mobile app). The display is pretty basic and comprises a black and white screen which is controlled by a light-sensitive backlight - but it all works very well. The PC8, however, doesn't need the extra garnishing, touchscreen functionality, colour screen and gimmicks of its rivals; it's a prime example of the less-is-more philosophy and we like that very much.
We particularly love the customisable, anodised aluminium chassis, which is available in ten different colours. Customers have the option of speccing the unit in their desired colour as well as choosing between eight different designs for the sides, including flags and other ornate graphics.
What to look for in a cycling computer?
Just like anything else in cycling, trying to figure out which bike computer will fall within your budget constraints while offering the features you prioritise, can be a tall order.
Depending on how much money you have to spend, your GPS computer may have base maps, interval timers, in-depth power metrics, a colour touch screen and more connectivity than you can shake a stick at, or it might be a simple, compact unit with a black and white display and basic training metrics.
Every cycling head unit on the market will give you data fields like speed, distance, and time. Even at the bottom end of the spectrum, most cycling computers will support and ANT+ or Bluetooth connection to a heart rate monitor plus speed and cadence sensors. However, some less-expensive units may not support power meters.
More cycling computers are beginning to work with both ANT+ and Bluetooth sensors now. There are still a few hold-outs sticking to one or the other, but the majority will facilitate a Bluetooth connection to your phone for on-screen notifications, firmware updates and the like. Further still, some devices also connect to your home WiFi network to allow for your ride to be on Strava before you’ve taken your helmet and sunglasses off.
Most bike computers feature a GPS chip, as well as access to other satellite networks like GLONASS, BeiDou, and Galileo, and offer some definition of navigation. Many also have a base map pre-installed which allows for turn-by-turn directions, on-the-fly redirection and some allow you to create routes and courses directly on the device.
More budget-friendly head units won’t have a base map, but may still offer what’s called ‘breadcrumb’ navigation, where the head unit will display your route as a line which you’re meant to follow.
As you go up in price, you get things like touch and colour screens, but these are not something you’ll necessarily need. While touchscreens are great for swiping through pages of metrics or manoeuvring maps, if you're wearing full-finger gloves or if it's raining, the screen may not function as advertised. The same goes for colour displays, which only really become a necessity if you’re using maps.
Finally, there are the extras like Komoot, Strava Live Segments, and on-screen workouts populated by Today’s Plan, Training Peaks and TrainerRoad, uploadable training metrics and data fields, drivetrain and light integration, the companion app and more.
Where these features are available will depend on the bike computer you choose, but they are not reserved for the premium units, and you’ll see features like Strava Live Segments and drivetrain integration trickling into mid and lower range units.
