If you’re shopping for a new bike computer and feeling overwhelmed by the sheer number of options, you’re not alone. These devices have become increasingly complex, boasting an array of features and enough metrics to dazzle even the most data-driven riders. The good news? Every bike computer performs the same essential function—recording and displaying ride data. Plus, most allow you to customize how much or how little information appears on the screen.

What to Consider in a Bike Computer
Technology Ecosystem
One of the biggest differences between GPS cycling computers is the technology ecosystem you’re buying into—much like choosing a smartphone. While you can pair most sensors, regardless of the brand, with most computers via Bluetooth or ANT+, these devices work best when used with their corresponding companion apps. Some budget-friendly options, like the Coros Dura, require the app to unlock full functionality, whereas premium models from brands like Hammerhead, Wahoo, and Garmin allow you to do more outside of the app.
Screen Size
While bigger isn’t always better, a large, easy-to-read display—like the one on the Wahoo ELEMNT Ace—can make navigation and data viewing significantly more convenient. When testing the gargantuan ELEMNT Ace, Test Editor Dan Chabanov noted that while he was initially put off by the sheer size of the screen, he grew to appreciate it.
Navigation
Navigation capabilities vary widely. Even budget models, such as the $200 Garmin Edge 130 Plus, support turn-by-turn directions with downloadable routes. High-end models like the Hammerhead Karoo take it further, allowing on-the-fly route changes—such as finding a coffee shop—without needing to adjust settings in the companion app.
Battery Life
Battery life was once a major concern, but modern bike computers are built to last. Most can handle a full week of riding without needing a recharge. Some, like the Coros Dura and Garmin Edge 1040, even feature solar charging. In fact, the Coros Dura’s battery is so robust that we haven’t yet been able to drain it completely, making its claimed 120-hour battery life seem entirely plausible.
How We Selected the Best Bike Computers
We spend thousands of hours on our bikes each year—riding familiar loops, mapping new routes, training for events, and competing. As tech enthusiasts, we track every ride using computers, watches, and smartphones. Having used GPS cycling computers since their early days—and wired cycling computers long before that—we know what works. These are the bike computers we trust most when heading out for a ride.

The Wahoo Elemnt Bolt V2 brings an excellent set of features together at a great price point, making it a strong option for a wide range of cyclists. It can generate bespoke turn-by-turn directions in addition to using preloaded route files (GPX, FIT, etc.), including directions from Ride with GPS, Komoot and Strava. It also offers advanced navigation options, including route to start, on-demand rerouting, and route retracing. It also integrates with TrainerRoad, TrainingPeaks, and Today’s Plan for structured indoor and outdoor cycling workouts.
The Bolt V2 features a 64-color, 320 x 240 pixel display–it’s not as sharp or vibrant as other, more expensive options, but the UI prioritizes information in a way that I find easy to read. Grade and climb profiles show difficulty by assigning different background colors related to the grade (red being the steepest). This makes it easy to see at a glance what that hill in front of you is going to be like. I also like its quick-look LEDs, which progressively illuminate in the direction of the route when a turn approaches. That said, it may look a bit small in a world of 6- to 7-inch smartphones.
As I mentioned, I tend to prefer Wahoo computers over Garmin. They feature an easy setup process and an intuitive companion app that connects to third-party tools easily. The Bolt V2 features 16 Gigabytes of onboard storage, which is enough to store maps for the United States and 1000’s of routes. While it’s far from the fanciest cycling computer, the Elemnt Bolt V2 gives you everything you need (and nothing you don’t).
Pros
- Intuitive touch screen
- Collects tons of data for varied training features
Cons
- Some lag in turn-by-turn directions

The Garmin Edge 840 drops only a few quality-of-life features found on top-of-the-line Edge 1040, but costs substantially less. It provides you with all the data you need to manage your training program and track your progress, including VO2 max output (when paired with your heart monitor), recovery time, training load, heat and altitude acclimation, as well as cycling dynamics like position, right/left balance (when paired with a power meter), and bike setup. If you love to pore over charts and analyze data, the 840 gives you a lot to look at.
The navigation system supports Garmin’s core feature-set, including ride-specific mapping, turn-by-turn directions, route calculation, and back-to-start if you decide you need to cut out early. It plays nice with all the usual cycling apps, with an added bonus for some e-bike riders: It supports Shimano’s Steps system, allowing you to track assist level, battery life and gear position when riding a compatible e-bike.
The fact that it’s equipped with both a touch screen and buttons earns it many points in my book, too, and makes it a great choice if you’re one of those people who don’t mind getting caught out in the rain.
The one complaint I’ve heard routinely about Garmin navigation from my own cycling community is that notifications sometimes lag and fail to show up until the moment you need to turn. In a group, you may find yourself suddenly yelling, “Slowing! Slowing! Right turn!” Or, worse, riding down a hill you weren’t supposed to as your riding partners scream into the wind that you’ve gone off course.
That being said, the 840 is an excellent option for riders who love the training and reflecting on their data. At less than $500, it offers a decent balance of price and feature set in the generally pricey Garmin bike computer lineup. That being said, upgrading to the 840 Solar, which extends the battery life to an impressive 32 hours, is a worthy splurge.
Pros
- Small and lightweight device
- Compatible with Varia lights and radar
- Can display most of the same data as larger, more expensive models
Cons
- Small screen can be hard to read
- Discontinued by Garmin, but still available at other retailers

If you're looking for a no-frills bike computer that covers all the essentials without breaking the bank, the Garmin Edge 130 is a solid choice. It’s compatible with most Bluetooth and ANT+ sensors and still has key features like waypoint navigation and turn-by-turn directions. In a market filled with bike computers that resemble mini tablets, the Edge 130 stands out for its simplicity. Unfortunately, Garmin has discontinued production, but if you want a reliable device that nails the basics, it’s still worth considering.
The main drawback is its small screen, which can make it difficult to view multiple data fields at a glance. However, if you prefer to focus on just a few key metrics during your ride and analyze the details afterward, this compact computer is a great fit.
Pros
- On the fly navigation features
- Easy to set up
- Reliable and waterproof
Cons
- Street names don’t show up on map

I’ve used many different bike computers, but the Wahoo Elemnt Roam V2 is the one that I use the most on my own time. I take it with me when I go exploring, either around the neighborhood or to far-flung places around the world. The original model accompanied me across Central Asia (from Beijing to Istanbul), and through the Karakoram Mountains in Georgia and Armenia.
With the Roam V2, Wahoo added more robust navigation features like Summit Freeride, which detects climbs even when you don’t have a route loaded, 32GB of storage, and a precise GPS thanks to a Sony dual-frequency GNSS chip.
I’ve found that the aforementioned GPS is among the most consistently stable I’ve tried, maintaining a signal even while pedaling in dense forest environments or through noisy urban areas with extensive obstructions. For example: There is a spot on the Manhattan side of the bicycle entrance to the 59th Street Bridge in New York City that takes you underneath multiple vehicle ramps and overpasses. I ride over this bridge for my commute, so I’ve noticed that most cycling computers lose connection there for about 20-30 seconds, but the Roam V2 always holds.
Beyond that notable reliability, the Roam V2 is a standard mid-tier bike computer. It features a slew of navigation features, including turn-by-turn directions, navigate to start, back on track, mountain bike trail integration, saved locations, retrace route, and take me to.
I appreciate many of its more basic, nuanced details, though. Its slightly raised buttons are easy to operate mid-ride. A USB-C cable charging means one less cable to carry when traveling. The reasonably sized color screen is easy to read at a glance.
If you’re an explorer like me and don’t need extensive bells and whistles in your cycling computer, the Roam makes a great travel and adventure companion.
Pros
- Long battery life
- Supports 80 different functions
- Easy phone integration
Cons
- No base maps

The Bryton Rider 420 has only the most basic black and white display, but trading in sharp, color-coded graphics nets you two things in return: An impressive 35-hour battery life (the best non-solar option among our picks), and an equally head-turning sub-$100 price. It gives you just the basics, recording up to 80 metrics including time, speed, altitude, power, heart rate, calories and distance for measuring and analyzing your rides and workouts.
Its navigation features include turn-by-turn directions; route sync with Strava, Komoot and Ride with GPS; and compatibility with various external sensors like power meter pedals and heart rate sensors. It also supports electronic gear shifting from Shimano, SRAM and Campagnolo.
The biggest flaw here–and it will be a dealbreaker for some riders–is that the Rider 420 doesn’t have any base maps, so it can only show you a breadcrumb trail without the context of nearby streets, paths and other landmarks. It’s a truly no-frills experience, bordering on retro, but that’s the absolute least you’re going to spend on a bike computer.
COROS DURA Solar GPS Bike Computer
Pros
- Incredible battery life

At $250, the Coros Dura is a remarkable value. The Wahoo Elemnt Bolt V2 ($280) and the Lezyne Super Pro GPS ($250) are the closest-priced competition. The Dura’s most notable feature is its claimed 120-hour run time. In Test Editor Dan Chabanov's testing of the device, he reported “I haven’t gotten that close to Coros’ claims, but I have recorded 61 hours of riding in between charges.” While the Dura is far from perfect, it does many of the basics well. You can pair almost anything with a Bluetooth or ANT+ connection, and if you like doing structured workouts, you can import existing workouts from Training Peaks, Intervals, and a long list of other training apps.
Given how many features Coros has already implemented or improved since we started testing the Dura last summer, and given its track record of doing this as a company in the watch space, Coros will keep improving the Dura. Unless a rider needs multi-day battery life, we're unsure if the Dura will be enough to tempt existing Garmin, Wahoo, or Karoo riders away from their feature-rich devices. But, for riders who only want a cycling computer that does the basics well and is literally half the price of many competitors, the Coros Dura is hard to look past.
Pros
- Seemless integration with third-party apps
- Fully recharges in 3 hours
- Great for on-the-fly route changes
Cons
- No Shimano integration
- Battery life isn't as robust as its competitors

The new Karoo (no, Hammerhead doesn’t call it Karoo 3), is mostly about refinement and addressing shortcomings. The new unit doesn’t look or function much differently than the Karoo 2 it replaced, but among the new features are a dedicated power button, better battery life, an ambient light sensor, and automatic backlight control. Plus it has a new companion app for your smartphone that offers automatic ride uploads and live tracking. More significantly, the new Karoo integrates more tightly with SRAM AXS components. Some examples of this include automatically pairing with your SRAM AXS-equipped bike’s components and the ability to program AXS shift buttons, as well as the new bonus buttons on the Red 2024 hoods, directly from the computer. We also love the immense amount of detail from our rides that companion app provides. We can spend way too much time pouring over lap-by-lap time, power, and gear selection data. If you love analyzing post-ride data, the Karoo and its companion app will give you a lot to appreciate. We love it so much it was a winner of Bicycling's Gear of the Year award in 2024.
Garmin Garmin Edge 1040 Solar Bike Computer
Pros
- Big screen
- Solar charging for exceptionally long battery life
- Lots of training features
- Better-than-average GPS accuracy
Cons
- Takes up a lot of space on your handlebars
Key Specs
| Overall Size | 2.3 x 4.6 x 0.8 in. |
|---|---|
| Display Size and Resolution | 3.5 in. (282 x 470 pixels) |
| Screen Type | Color, touch screen |

By adding solar charging, the Garmin Edge 1040 Solar improves what was already one of the most robust, feature-rich bike computers around. Using Garmin’s energy-capturing Power Glass, it can last through up to 45 hours of standard use, or up to 100 hours in battery saver mode.
That would be impressive in itself, but it's compounded by the fact that the Edge 1040 features a comparatively large 3.5-inch color touch screen and range of features you won’t find elsewhere. Event-specific training plans and suggested workouts let you tailor your preparation. Nutrition and hydration alerts help you optimize performance in the moment. Extra cycling metrics like length of ride, bike position, and ambient temperature help you chart performance long-term. For mountain bikers, it also measures the difficulty of a ride (grit) and how smoothly you descend.
Navigation features (powered by multi-band GNSS technology) include turn-by-turn directions, ride-specific maps that show popular routes used by locals wherever you are, and off-course recalculation that you’re able to pause in the event you’re in an exploring mood.
As a mountain biker, I particularly love its integration with the MTB-specific Trailforks app and Forksight mode (a Trailforks feature) which provides a zoomed-out map of where you are in a trail network as you approach a fork (context, as anyone who routinely rides trails knows, is everything).
Lastly, Garmin has added some thoughtful safety features, including the ability automatically sending an emergency message to your specified contacts when it detects a crash, group messaging, and a ‘follow my ride’ that shares your real-time position with friends and family.
With so much to gush about, you may be asking why this isn’t our top pick. Realistically, the answer comes down to one word–price. At more than $700, it’s at least a couple hundred dollars more expensive than every other option on our list. The price drops to $600 for the standard Edge 1040 without solar charging; That’s still a pretty penny, though. We love this bike computer and all the things it can do, but the price tag makes it hard to justify unless you’re training for competition.
Pros
- Huge screen that's very easy to read
- Impressive battery life
- Excellent navigation features

Wahoo goes literally huge with its newest computer, the Elemnt Ace. The screen’s real estate is impressive, as is the battery life (up to 30 hours), and it features Wahoo’s signature user-friendliness. The large screen area offers room for large and easy-to-read data fields, and the touchscreen is fantastic, even while wearing gloves. Wahoo’s signature page zoom function—use the up and down buttons to zoom in on fewer fields or out on more fields—quickly makes prioritized fields even larger. This is helpful if you want to concentrate on one metric and for riders with vision challenges. It also provides a very big map (or a large map plus additional data fields) and spoken turn-by-turn directions. Viewed through the lens of our everyday cycling computer needs, the Ace is overkill. But if you want one computer with a big screen and impressive battery life and you crave big and bold, that is the Ace.
