The best GPS bike computers allow you to tackle unfamiliar routes with ease and track your essential ride stats right from your handlebar. These bike computers have GPS onboard to accurately track your location too.
But it's hard to know how they'll perform until they're actually out on a cycle. That's why we put them to the test to find the best GPS bike computers that are actually worth your money and can keep your focus on your ride, not the tech.
Our top choice is the Wahoo Elemnt Bolt V2, which is incredibly easy to use, accurately monitors your location, and won't break the bank. Or if its longevity you're after, we recommend the Coros Dura, which lasts an incredible 120 hours.
But these aren't your only choices, as we've rounded up the best bike computers you can get right now across a range of budgets, uses, and activities, including wrist-based trackers that can see you through multi-sport activities like triathlons.
The quick list
Easy to setup and use, the Wahoo Elemnt Bolt V2 is the best GPS bike computer for most people. It’s compact but easy to read, and it’s a breeze to change screens quickly on the move.
The Elemnt Roam is the bigger brother of the Elemnt Bolt. It features a slightly larger screen a slightly longer battery life and an identical button layout compared to the Bolt.
The Wahoo Elemnt Rival wristwatch is a good form factor for multi-sport athletes who may go from running to biking to swimming — sometimes in that order in the form of a triathlon.
The Garmin Edge Explore 2 is designed specifically with e-bikers in mind, and as it connects to your bike's power, you can keep it powered up on long rides. The screen is clear and setup was quick and easy.
Garmin integrates Power Glass into the Edge 840 Solar’s screen face, which allows the unit to charge off the sun while you’re riding, making it great for long rides.
If your primary goal is exceptional navigation, the Hammerhead Karoo 2 can’t be beat. The bright, anti-glare, color touchscreen makes it easy to pick out details on the map and route-finding is super-easy.

Best GPS bike computer overall
The Elemnt Bolt has long been my go-to GPS bike computer due to its super-simple setup and pairing and easy user interface. It’s compact but easy to read, and it’s a breeze to change your screens at the press of a button. Navigation is very good, though perhaps not as quick and clear as Hammerhead’s Karoo 2.
The 2.2-inch display is easy to read and features selective color to make important bits of information easier to see. Wahoo claims a 15-hour battery life, and in my experience, that is a good estimate if you’re being conservative with your screen brightness and navigation use.
The Elemnt Bolt features 16GB of storage, so you can upload maps, rides, and workouts. However, if you regularly add new routes, the Garmin Edge 840 Solar might be a better option, with double the amount of storage (32GB)
It mounts to your handlebars with a proprietary aerodynamic mount that seamlessly integrates with the shape of the computer itself. Overall, the Elemnt Bolt does everything a good GPS should do without a lot of fluff, all at a decent price.
Best GPS bike computer with maps
The Elemnt Roam is the bigger sibling of the Elemnt Bolt. It has a slightly larger screen (2.7 inches versus 2.2 inches on the Bolt) a slightly longer battery life (17 hours versus 15 hours) and an identical button layout compared to the Bolt.
The big difference is under the hood. The Elemnt Roam features dual-band GPS, while the Bolt features single-band GPS. That means the Roam’s global positioning should be slightly faster and more accurate than its smaller sibling.
The Elemnt Roam is just as great as the Elemnt Bolt but with a larger footprint. I personally like the Bolt’s smaller footprint, but with added GPS accuracy, you may find the Elemnt Roam worth the extra size.
Best GPS bike computer for multi-sport athletes
The Wahoo Elemnt Rival looks like a watch, because it is. This bike computer is designed for your wrist, rather than your bike's handlebars. It also means that it's a more versatile device if you sports or activities outside of cycling.
The multi-sport features, like touchless transition, are ideal for triathlons, so you can switch between activities without tapping the watch. And the multi-sport handover means it can connect to a separate dedicated GPS bike computer.
Like many of the best sports watches, the Elemnt Rival has an optical heart rate monitor built in, so you can even do some sleep-tracking with the watch. And you can pair the heart rate monitor to your GPS cycling computer too.
The only complaint I had was how long it takes for the watch to get a connection to satellites. It seems to take longer than most GPS cycling computers, but this isn’t a deal breaker. We’re talking a few minutes, after all.
Best GPS bike computer for e-bikes
If you're after a GPS bike computer for one of the best electric bikes, the Garmin Edge Explore 2 is specifically designed with e-bikes in mind. Even if your e-bike has a display, the Edge Explore 2 allows you to see much of the data you’d see on a typical e-bike screen
Plus, you get vastly more powerful capabilities and excellent navigation. The computer integrates easily with Shimano Steps motors and uses ANT+ to connect with other systems. The 3-inch touchscreen screen is crystal clear, too.
It looks narrower than the Hammerhead Karoo 2 screen, though. The setup was quick and easy; I was able to get on my bike with minimal faffing about ahead of time. And since you can plug the device into your e-bike, it can stay topped up.
Best GPS bike computer for touring
One of the most interesting aspects of the Garmin Edge 840 Solar is the use of Power Glass, which allows the unit to charge when in sunlight, even when powered off. Garmin says you should get 60 hours from the unit in power-saving mode, or 32 hours of regular use.
I set my unit out to charge in the sunlight for ten minutes. The screen told me I was charging at a 47% intensity of sunlight, and after 10 minutes I had gained 5% of my battery life. It’s an excellent feature if you’ll be out in the sun all day.
If you live in a place where sunlight isn’t always shining bright, the solar function may not benefit you and you can save yourself a few bucks by downgrading to the Edge 840, minus the solar charging.
The mapping and GPS system on the Edge 840 is excellent and very accurate, and you can store up to 32GB onto the device. It’s just as good as the Hammerhead Karoo 2 — which bests the Edge 840 Solar in screen size. The Karoo 2 features a 3.2-inch screen, while the Edge 840 Solar’s screen is 2.6 inches.
Garmin packs the Edge 840 Solar with features like address search, which you can use on the fly while out riding. ClimbPro lets you see upcoming climbs without having to upload a course beforehand.
Best GPS bike computer for navigation
The Karoo 2 is the bike computer to beat for exceptional navigation. The bright, anti-glare touchscreen makes it easy to pick out map details, and route-finding is super-easy whether you've pre-uploaded a route or you're doing it on the fly.
There's 32GB of onboard storage, so you’ll have plenty of space for uploaded routes. You can also set routes right on the computer while you’re riding. And if you miss a turn, the Karoo 2 features instant automatic rerouting.
The touchscreen toggles on and off, so if you’re not interested in accidental taps, you can tailor your experience and just use the physical buttons. Hammerhead frequently releases software updates — enough that you might find it annoying.
The advertised maximum battery life is 14 hours. That’s lower than most of the Karoo’s competition, and in practice, my battery life was closer to 9-10 hours. The device has a unique mount, but it doesn't do anything the Garmin-style mounts can't. Fortunately, the Karoo 2 has an adaptor for you to use Garmin mounts.
The desktop dashboard offers plenty of data analysis and ride-tracking potential. But there’s no app to upload your ride right away. You’ll need to connect to Wi-Fi to get your ride data from the Karoo 2 to your computer dashboard. But the Karoo 2 also supports 4G LTE with an optional SIM card.
Best GPS bike computer for battery life
The Coros Dura has a whopping 120 hours of battery, which means you can certainly say goodbye to battery anxiety. And the solar rechargeability means you can top it up with an extra two hours of power for every hour of ride time.
After a nearly three-hour ride, our test unit still read 100% battery life, blowing away its nearest competition. You don’t need to turn the unit off (though you can, deep in some of the menus), as it goes to sleep on its own.
There's a knob that allows you to scroll through screens quickly, though it’s super sensitive and difficult to use accurately while riding. The included mount does not mate with the head unit tightly enough, leading to some rattling, though Coros has said they're going to address this in future production runs.
The mapping is good but not great. On-device re-routing can only be done when you’re in cell service or Wi-Fi range. It relies on Google Maps information, so dirt or gravel roads may not show up. Some of the on-screen climb data and visualization is useful but could use some refining to better service the rider’s needs in real time.
Pairing the Dura to ANT+ and Bluetooth accessories was quick and easy. And the Dura found a GPS signal much more quickly than many of its competition. It’s easy to pair to your electronic shifting system, too, though you may not find your specific gear range listed.
How we test the best GPS bike computers
I used each one of the units in this test personally on my bicycle rides. In testing, the first step is to understand the out-of-the-box setup process. Easier is usually better, though some computers with a more intensive setup process also offer more features once the setup is complete.
From there, each computer gets mounted to the bicycle so I can get a sense of how solid and user-friendly the mount that’s included with each unit can be. Then, it's time to check how easy is it to simply get pedaling, with no other adjustments or pairing.
After, I consider how easy is it to pair devices, navigate through menus and set the screens up the way I like. Then, it's time for a ride to test the GPS abilities, including how quickly each unit links up to GPS satellites, how accurate the turn-by-turn directions are, and how easy it is to set and follow routes.
Battery life can be a tricky aspect to test since battery life varies drastically depending on whether you’re using navigation, what the ambient conditions are outside during your ride, whether you have several sensors paired to the computer.
How to choose the best GPS bike computer
When choosing the best GPS cycling computer for you, start by determining what data is most important to you: GPS wayfinding, or other features like power data, movement capture, clear screen optics, etc.
Or perhaps size and/or price is your north star. There are GPS cycling computers available to support just about any price point, and if you want just a simple, small unit, such computers still offer lots of information and powerful navigation.
If you’re a multi-sport athlete — you’ll want to track your activities on the bike, running, skiing, swimming, etc. — a wristwatch-style GPS computer, instead of the usual handlebar-mounted device, may be your best bet.
FAQs
What is a GPS bike computer?
A GPS bike computer is an electronic unit that usually mounts to a bicycle’s handlebars so the rider can see the computer’s screen in real-time. A GPS computer can include many types of information, but its global positioning system (GPS) features define it.
GPS computers use satellites to locate the rider’s position, often down to 3 feet of accuracy or less. This allows the rider to not only pinpoint their current location, but also find routes, get turn-by-turn directions, or even find landmarks along the route the rider has chosen.
Most GPS cycling computers give the rider other advantages besides navigation. A typical cycling computer will show the rider a current speed, max speed, average speed and elapsed ride time, as well as the current time of day.
Some more advanced units can pair via Bluetooth to external sensors, like a power meter or heart rate monitor. That means the rider can get power and heart rate data while riding, right on their GPS cycling computer screen.
What does GPS stand for?
The Global Positioning System (GPS, is a satellite-based navigation system that allows you to find your location accurately. This means you can get turn-by-turn directions, see maps on your screen, pre-map a ride and load it onto your computer to follow it, and much more. GPS opens up a ton of wayfinding possibilities.
Do I need a bike computer?
You don’t need a GPS cycling computer to go out on your bike and have a good time. But you’ll want one if you are in need of a navigation device, or if you want to track your ride data (top speed, current speed, ride time, wattage, etc.).
Can you conserve battery on a bike computer?
It seems odd to say it, but the best way to conserve your battery life is to turn off navigation features. If you already know the route you’ll be riding, there’s no need to have features like turn-by-turn directions active.
Any time your computer uses navigation features, the battery will drain more quickly. To circumvent battery stress, Garmin created a unique solar charging system that’s used on the Edge 840 Solar.
What's the difference between single-band and dual-band GPS?
A single-band GPS receives information from satellites on one frequency. A dual-band system picks up information on different frequencies, which makes it more accurate and precise in certain situations.
Dual-band GPS computers will perform better where there is more interference — in cities where signals are reflecting off buildings, for example.
But most cyclists will probably be just fine with single-band GPS signals; dual-band signals often produce accuracy numbers within centimeters, while a single-band GPS may deliver results within a three-foot or less accuracy.
What is GNSS?
GNSS is the Global Navigation Satellite System. This system includes GPS, GLONASS, Galileo, and other satellite systems. If your bike computer has GNSS, that means it will be more useful and accurate in more places worldwide.
