Best bike computers 2025: Our top-rated GPS-enabled computers for routing and training

The best bike computers now pack a lot of power and are loaded with features way beyond just tracking your ride, with some nearing the capability of a smartphone. They can amass vast amounts of data about your ride to be analysed on the move or at home on one of the many best cycling apps.

The latest computers are packed with features and technology that most users will never find a use for. Take the Garmin Edge 1050, a sim card short of being a smartphone, it will now let you pay for your mid-ride coffee and even has an electronic bell. More basic options come backed with plenty of training features and include connecting to your phone for alerts, heart rate monitors and power meters.

This guide features our top-rated and reviewed best bike computers, of which we rate the Hammerhead Karoo as the best cycling computer you can get your hands on. Its large touchscreen is flawless; however, it's the Karoo's user-friendly operating system and new app that make it such a joy to use. I would like to give an honourable mention to the Garmin Edge 540. The 540 has everything you need and nothing you don't, known for being a reliable and bug-free unit. It would be rude not to mention the Coros Dura, a relatively new entrant. It boasts an almost unbelievable battery life, ideal for bikepacking and endurance rides.

The Quick List

Our top picks: The best cycling computers

Best overall

The Karoo's predecessor, the Karoo 2, had gained a pretty loyal following in recent years thanks to its excellent display, open-source navigation and an Apple-like commitment to software updates. Could the latest version address some of the minor issues of the previous model, but continue to dispute Garmin and Wahoo's stronghold on the bike computer market?

The short answer is yes, the Hammerhead Karoo takes everything that was great about the Karoo 2 and, with an incremental improvement approach, has made something that is even better.

A big part of this improve comes in the form of Hammerheads new companion app, that effectively completes the ecosystem. It offers users a more seamless experience as well as an easy way to plan and review routes, view current and previous data and live tracking.

One area Hammerhead still struggles against its competitors, and especially with Coros making enormous strides in this area, is the battery life. All I put this down to is that the amazing processing power and performance of this computer is understandably energy-sapping. However, this was an issue with the previous model also, and one Hammerhead do claim to have improved. I am inclined to agree, as previously it was as low as 7 hours, and now I was with every trick I know to conserve battery to get 10 hours. While this will likely be enough for most, it is still maybe only one or at most two weekend rides, versus that of my beloved Garmin Edge 540 Solar, which manages nearly two days.

That said, it is still my favourite bike computer and retains its best overall status.

Best value

We are big fans of Wahoo's cycle computers for their ease of setup and bombproof software.

The Wahoo Elemnt Bolt has received an upgrade with more memory and a color screen. It's still button-operated rather than its 2.2" screen being touch-sensitive, but the buttons are now convex for easier operation, particularly when wearing gloves.

Set-up, pairing to a smartphone and configuration remain super-easy though and data is clear and legible. The LED array can help guide you too, although we didn't find it very useful.

Mapping and route management have been upgraded as well and there's clear turn-by-turn navigation and plenty of onboard map coverage without needing to download more basemaps. Navigation can be hit-and-miss though in our experience.

Other features include structured workouts, Strava Live integration and multisport handovers, as well as the newly-added Summit Climbs that give you a gradient profile for a pre-mapped route. Battery life is around 15 hours and there's quick USB-C charging.

Best value Garmin

Garmin really stepped up the performance with the 540, while keeping key features which its predecessor the Edge 530 had become so well known for.

The 540 is now truly the entry into Garmin's range of training and performance-based computers. This is despite Garmin offering the more affordable and brilliant Edge 130 Plus. With the addition of the Climbpro, course demands, multi-band GNSS and power guide features, you could say Garmin needn't have gone further than that. It is the inclusion of Garmin Coach, found on the Edge 840 and 1050 that really takes the 540 to the next level.

Mapping also saw big upgrades with features like popular roads and trails and a much bigger catalogue of POIs. Living in Spain, especially in the Summer you are acutely aware of your water supplies, so the addition of simple things like water fountains could be a literal lifesaver.

Whilst I would prefer a touchscreen and as I mentioned riding in Spain means I am less often using gloves, like those in the UK or cooler parts of the US. I can see that the button operation could be a big draw for a lot of people. Considering the Edge 540 is now available in a Solar version, it is hard to see why you would choose the Edge 840 over this.

Best for navigation and mapping

The Edge Explore 2 is a kind of antidote to the all-singing, all-dancing, solar-powered Edge 1040 Solar. It costs less than half as much as the 1040 and it’s aimed at the rider who doesn’t need all the performance metrics or the outdoor structured workouts. There’s also no Strava Live Segments. That said, it will pair with Bluetooth and ANT+ sensors, sync everything with Garmin Connect (via Bluetooth; it doesn’t have WiFi), upload to Strava and other training apps and give you smart notifications, group ride messaging and incident detection - always handy.

If you've been using a heart rate monitor and power meter you'll get 'Highlights' after finishing your ride - a new V02max (if applicable) and recovery time - which feeds into Garmin Connect once synced and adds to your overall fitness data if you're tracking it.

So although navigation is the Edge Explore 2's primary function - and it does it incredibly well - training is by no means neglected.

In testing we found the Edge Explore 2 easy to set up, easy to use, easy to afford (relatively speaking) and ideal for most cyclists most of the time. It doesn't have the largest range of options (only three activity profiles for example) or the latest version of ClimbPro, and it's a shame you don't get an out-front mount in the box, but overall it's a great unit for the money.

Best screen and features

The Edge 1050, Garmin’s flagship bike computer, boasts a spec so massive that few of us, myself included, are ever likely to use every feature in anger. Here’s a quick, whistlestop tour. It features turn-by-turn navigation with auto-rerouting that’s impressively accurate, even under tree cover, thanks to multi-band GNSS that uses GPS, GLONASS and Galileo. Training and performance functions include a power guide, stamina insights, cycling dynamics, grit and flow metrics, cycling dynamics, hydration alerts, heat and altitude acclimation, training status, suggested workouts, on-device course creation, road hazard alerts, group ride tracking… OK enough already.

The thing is, Garmin’s less pricey Edge 1040 and 840 computers all share the same features, plus better battery life to boot. So, where’s the value in the Edge 1050? As soon as I switched it on, it became blindingly obvious. The super-bright, high-resolution, 480 x 800-pixel screen offers up 88.9 mm (3.5″) of vivid, high-contrast, visual loveliness. It’s so colourful and crisp it makes Garmin’s other computer displays look washed out and fuzzy, even more so under bright sunshine and contrasty lighting conditions.

The Edge 1050 is also the first Garmin bike computer to feature Garmin Pay, which some riders will rate, but, as an existing Apple Pay user, I found it redundant. I was much more impressed with the built-in full-range speaker that generates proper tones and smooth, easily understandable voice commands. I won’t miss the 80s-style, 8-bit, chip-tune prompts that date the rest of Garmin’s range.

The speaker has enabled Garmin’s engineers to include another exclusive, yet quirky, feature that I found myself using all the time. A built-in bike bell that sounds just like the real thing. Tap the screen once to reveal a button, then hit that to emit a loud tone. Genius. Even better, if you have SRAM bonus buttons you can dedicate them to control it.

The Edge 1050’s battery life is less than the 1040 and 840, and substantially less than the 1040 Solar, but rated for 20 hrs of intensive usage, it still has enough juice to last two weeks of riding for most of us.

Is it worth the premium over the Edge 1040? If you’re choosing between the two, then definitely. If you’re looking to upgrade from the 1040, then the choice is less clear but, frankly, that screen is very seductive.

Best battery life

I received my test unit only a short time before the launch, which gave me limited time with the Coros. Initial impressions are the unit is small, super light and thin. Up against a Garmin Edge 1040 and Hammerhead Karoo, considering the claimed battery life it's a similar size to both, which is impressive.

The 'crown' similar to a watch winder (Which is what Coros is known for) might be a welcome sight for those needing to ride with thick gloves in winter, allowing you to navigate settings and pages.

I did experience a few hiccups in the first few rides, largely due to many features not being available until public launch time. I am told by Coros that a lot of these have updates coming or already fixed. This could be put down to a lack of familiarity with the new ecosystem. Unlike Garmin and Wahoo, a lot of the Dura's settings need to be set within the app rather than on the device itself.

Let us get to that battery life. After a week's riding including a big eight-hour-long backcountry ride, I still had 70% battery left. When I first spotted the Coros at Unbound, Haley Smith said "I have yet to charge the unit since receiving it at the Sea Otter Classic – 90 hours of riding time and counting". Time will tell truly how long the battery will last but initial impressions look good.

Best for simplicity

I find myself increasingly being put off by tech, call it age, call it just the vast amount of it in our lives, but for a Cycling Tech Writer, it is very much an oxymoron. I have always thought there was a gap in the market for those who don't really need training aids but like to track rides and need some simple navigation.

Enter the Beeline Velo 2!

This compact and light 28g/08oz device is not much wider than most modern stem top caps, yet despite that, it seems to catch the eye of anyone near my bike. The Beeline is incredibly simple to use and set up, while the first time around, I clumsily got it running (I should have just watched the tutorial first), it became a breeze to get routes from Komoot and Strava.

While my distance perception is not the best, the Beeline gives you plenty of warning of turns, with on-screen and sound alerts. I also used the app's navigation feature, which is very similar to Google Maps, to navigate to a cafe in a town in the southern German Black Forest, without taking a single wrong turn. So, even on-the-fly changes to your route or spotting a POI are not an issue and require very little input from the user.

Aside from the main focus of navigation, you get screens for time, distance to your destination, speed (miles or kilometres per hour), a stopwatch, both devices' battery levels, hill/ climb stats and an End or Stop screen to end the route. I found that, really, the only slight disappointment was the battery life, with the best I got being around 7-8 hours. Which, given the Velo 2's sizes, isn't bad at all.

All said and done, I was able to easily navigate a 60-mile route in the Black Forest and then head straight into the city without ever getting lost and not once did I miss any performance stats or feel I needed more.

Best budget

Tested alongside a Garmin Edge 530, the Cateye Quick mirrored the more powerful unit digit for digit in terms of speed and distance accuracy. Not bad for such a simple and relatively, in the scheme of things, cheap unit.

It’s also easy to read at speed and the out-front position puts it neatly in the field of view. As with all of Cateye’s simple computers, the battery life is measured in years rather than hours.

With the delightful simplicity, you do limit functionality. There isn't any compatibility beyond the wireless speed transmitter and you won't get a record of where you've been as there's no GPS chip on board. But if you are looking for a neat and simple cycling computer and don't need connected features, the Cateye Quick is accurate, reliable, and best of all looks really cool.

Best for training

The ability to charge the Edge 1040 Solar via the sun is quite the attention grabber. Garmin says the Power Glass™ solar charging extends battery life up to 42 minutes per hour in battery saver mode, giving you up to 45 hours of battery life in what it describes as "demanding use cases" and up to 100 hours in battery saver mode.

It's worth noting that this is based on an assumption of continuous 75,000 lux conditions during daytime rides. Essentially that means consistently bright sunshine that you may well enjoy during summer rides but, depending on where you live, are less likely to experience during the cooler seasons. Naturally, your expectations should match the amount of cloud cover.

The Garmin Edge 1040 Solar also features a revamped user interface that we found to be far easier to navigate than other Garmin models. The home page features customizable data fields so you can easily scroll through your recent activity history, training schedule, weather forecast and more. You can also view data such as your recovery time using the 'glances' feature.

Other interesting features include the Power Guide, which generates a pacing strategy for your chosen route to help you best manage your efforts. Naturally, all this tech doesn't come cheap, but if you're after an all-singing, all-dancing cycling computer you're unlikely to be disappointed.
