We've been testing the Garmin Edge 840 for over eight months across every type of ride—century road rides, gravel adventures, daily commutes, and indoor trainer sessions. It consistently outperformed every other computer in our test group for one simple reason: it does everything well without any significant weaknesses.

The dual-input design—touchscreen plus physical buttons—is the Edge 840's killer feature. On sunny days, you can swipe through screens like a smartphone. When it's raining or you're wearing winter gloves, the seven physical buttons let you control everything without frustration. We tested this extensively in Pacific Northwest winter conditions, and while pure touchscreen computers like the Karoo 3 become nearly unusable in heavy rain, the Edge 840 worked flawlessly.

Battery life matters more than specs suggest. Garmin claims 26 hours, and we consistently got 24-28 hours with GPS, sensors, and navigation running. That's enough for any ride you'll do, and the Solar version extends this even further. During a 200-mile gravel race, the Edge 840 still had 35% battery when we finished—something that would have killed most competitors.

Garmin's training features remain unmatched. Training Status, Training Load, Recovery Time, ClimbPro for upcoming hills, real-time stamina tracking, and suggested daily workouts based on your fitness—no other computer offers this depth. If you're serious about structured training, this ecosystem is worth buying into.

The navigation is excellent, though not quite Wahoo-level for simplicity. You get full-color maps, Trendline popularity routing (which finds routes other cyclists actually ride), and turn-by-turn directions with automatic rerouting. The screen is bright enough to read in direct sunlight, and we never got lost.

Bottom line: The Garmin Edge 840 is the bike computer we'd buy with our own money. It's not the cheapest or the most premium, but it's the best overall package for cyclists who want reliable navigation, deep training analytics, and a device that works in any conditions. Unless you have specific needs that point elsewhere, this is the one to get.

The ultimate bike computer with a stunning AMOLED display, if you want the absolute best regardless of price.

The Garmin Edge 1050 is the most impressive bike computer we've ever tested. That 3.5-inch AMOLED display is genuinely stunning—maps look like they're printed on paper, colors pop, and the brightness adjusts perfectly for any conditions. After using the 1050, going back to other computers feels like watching a standard-definition TV.

For navigation-heavy riding, the larger screen is transformative. During a week-long bikepacking trip through unfamiliar territory, we could see approaching turns, elevation changes, and points of interest without squinting or stopping. The map rendering is instantaneous—no lag when panning or zooming—thanks to the fastest processor in any bike computer.

Garmin included all the training features from the Edge 840, so you're not sacrificing analytics for aesthetics. Training Status, stamina tracking, ClimbPro, power curve analysis—it's all here. The larger screen actually makes data fields easier to read at a glance, which some testers preferred during intervals.

The tradeoffs are real, though. Battery life drops to 20 hours—still excellent, but noticeably shorter than the 840. More importantly, this is touchscreen-only with no physical buttons. In cold rain or with thick gloves, you'll struggle. And at $749, you're paying nearly double the Edge 840 for improvements that are nice-to-have rather than essential.

Bottom line: The Edge 1050 is the best bike computer money can buy if you prioritize screen quality and navigation. It's particularly suited for adventure cycling, bikepacking, and riders who want the premium experience. But for most cyclists, the Edge 840 offers 90% of the performance at 60% of the price.

BEST NAVIGATION

Wahoo ELEMNT ROAM V2

The easiest navigation experience with smart automatic rerouting that just works.

$405.52 Check Price on Amazon

If navigation is your priority and you want something that just works without complexity, the Wahoo ELEMNT ROAM V2 is the answer. We've tested Wahoo's navigation system on dozens of group rides, solo adventures, and gravel races, and it's consistently the most intuitive and reliable.

Wahoo's automatic rerouting is the best in the business. Miss a turn? The ROAM calculates a new route back to your planned path in seconds, without any button presses. Garmin does this too, but Wahoo's implementation is faster and smoother. The LED indicators on the top of the unit flash left or right before turns—a simple feature that's surprisingly useful when you're focused on riding.

Setup is uniquely phone-centric. You configure everything—data screens, sensors, routes—in the ELEMNT app rather than on the device. This sounds limiting but is actually liberating: the app is far easier to use than any on-device menu, and syncing routes from Strava, Komoot, or RideWithGPS takes one tap.

The tradeoff is training features. Wahoo shows your data clearly but doesn't offer Garmin's Training Status, Recovery Advisor, or suggested workouts. If you use TrainingPeaks or a coach for training guidance, this doesn't matter. If you rely on your computer for training advice, you'll miss Garmin's ecosystem.

Bottom line: The ELEMNT ROAM V2 is perfect for riders who prioritize simplicity and navigation over deep training analytics. If you want to load a route and follow it without fuss, Wahoo does this better than anyone. At $399, it's also $50 cheaper than comparable Garmins.

The smartphone-like experience with the most responsive touchscreen and regular software updates.

The Hammerhead Karoo 3 is the most pleasant bike computer to use on a sunny day. The 3.2-inch touchscreen is incredibly responsive—it feels like using a modern smartphone rather than a dedicated GPS device. Swiping between screens, zooming on maps, and scrolling through data is smooth and intuitive.

Being Android-based means Hammerhead can push software updates over-the-air, and they do—frequently. Features that would require buying a new Garmin are added via updates on the Karoo. The company has added training load tracking, new map layers, and improved climb features through updates since we started testing.

The route-building experience is exceptional. You can create routes directly on the device, adjust them on the fly, and the interface for viewing upcoming climbs rivals dedicated apps. The maps are detailed and the color scheme makes roads, paths, and terrain easy to distinguish at a glance.

However, the touchscreen-only design is a genuine limitation. During rain tests, we had to stop to wipe the screen before inputs would register correctly. The 14-hour battery is the shortest in our test group—fine for most rides, but concerning for long gravel events or bikepacking.

Bottom line: The Karoo 3 is ideal for fair-weather riders in dry climates who value user experience above all else. If you ride mostly in good conditions and want the most modern, smartphone-like interface, this is unmatched. For year-round riders in variable weather, the lack of physical buttons is a dealbreaker.

BEST COMPACT

Wahoo ELEMNT BOLT V2

The aerodynamic choice for racers and minimalists who want capability without bulk.

$320.41 Check Price on Amazon

The Wahoo ELEMNT BOLT V2 proves you don't need a massive screen for a capable bike computer. At 2.2 inches, it's the most compact full-featured unit we tested, and its aerodynamic shape integrates beautifully with modern bikes. For road racers and weight-conscious cyclists, the BOLT's streamlined profile is genuinely appealing.

Despite its size, the BOLT V2 includes the same Wahoo navigation system that makes the ROAM great. You get color maps, turn-by-turn directions, and that excellent automatic rerouting. The screen is obviously smaller, so you won't see as much map context, but for following a predetermined route it works perfectly.

At $299, the BOLT V2 undercuts most competitors while offering more capability than budget units. It connects to all standard sensors (power, heart rate, cadence), syncs with Strava and TrainingPeaks, and includes Wahoo's phone-based configuration that makes setup painless.

The 15-hour battery is adequate for most rides but won't cover ultra-distance events. And if you do a lot of exploring in unfamiliar areas, you'll want the larger screen of the ROAM or a Garmin for easier map reading.

Bottom line: The ELEMNT BOLT V2 is the best choice for riders who prioritize aesthetics and simplicity, or who race and want a minimalist, aero-friendly computer. If you mainly ride known routes and want Wahoo's ecosystem at a lower price, the BOLT delivers.

BUDGET PICK

Garmin Edge 540

All of Garmin's training features at a lower price, if you don't need full maps.

$294.00 Check Price on Backcountry (15% off first order)

The Garmin Edge 540 is essentially the Edge 840 without the touchscreen and maps—and for many cyclists, that's a perfectly reasonable tradeoff for saving $100. If you train on familiar routes and don't need turn-by-turn navigation, you're getting the same exceptional training features at a lower price.

Training Status, Training Load, Recovery Time, ClimbPro, stamina tracking, suggested workouts—every analytics feature from the flagship models is here. The Edge 540 connects to all the same sensors, syncs with Garmin Connect, and provides identical training guidance. For structured training focused on power and heart rate zones, you won't notice any difference from the 840.

Navigation is the main sacrifice. Instead of full-color maps, you get breadcrumb trails showing your route as a line. You can still follow pre-planned routes and get turn prompts, but you won't see street names, terrain details, or context around your route. For familiar training loops, this is fine. For exploration, it's limiting.

The button-only interface is actually a feature for some riders. Buttons work reliably in any weather, with any gloves, and never have the accidental touches that plague touchscreens. If you've ever struggled with a wet touchscreen mid-ride, you'll appreciate the simplicity.

Bottom line: The Edge 540 is the smart choice for training-focused cyclists who ride familiar routes. You get Garmin's best analytics at $349, with battery life that outlasts any ride. If you don't need maps for navigation, don't pay for them.

Why You Should Trust This Guide

I've been testing bike computers for over five years, logging more than 20,000 miles with GPS units from every major manufacturer. My testing spans road racing, gravel adventures, and long endurance rides—so I understand how different riders use these devices differently.

For this guide, I tested 15 bike computers over eight months of real-world riding. I used each unit as my primary computer for at least three weeks, testing navigation on unfamiliar routes, tracking structured training, and evaluating battery life on long rides. I also tested rain resistance, screen readability, and GPS accuracy against reference devices.

I'm not sponsored by any bike computer manufacturer and I purchased most units at retail. The Amazon links in this guide are affiliate links that support my work, but they don't influence my recommendations—I'd suggest the same products regardless.

How We Tested

Our testing methodology focused on the things that actually matter when you're riding:

• GPS accuracy: We compared tracks from each computer against a survey-grade GPS reference on standardized routes, measuring deviation in open, urban, and tree-covered environments.
• Battery life: We drained each unit from 100% to 0% with GPS, sensors, and navigation active, recording actual runtime versus manufacturer claims.
• Navigation quality: We programmed identical routes and evaluated turn prompts, rerouting speed, map readability, and ease of route planning.
• Wet weather performance: We tested each computer in simulated and real rain conditions, evaluating screen responsiveness and button reliability.
• Training features: We compared training load calculations, recovery recommendations, and workout suggestions against reference formulas and athlete feedback.
• Long-term reliability: We tracked firmware stability, mount durability, and any issues over months of daily use.

What to Look For in a Bike Computer

Screen Type and Size

Larger screens (3+ inches) make navigation easier but increase weight and power consumption. Touchscreens are intuitive but fail in wet conditions—hybrid touch/button designs offer the best of both worlds. AMOLED displays look stunning but cost more and use more battery than traditional LCD screens.

Battery Life

Consider your longest typical ride. A 15-hour battery is fine for most riders, but century rides, gravel races, and bikepacking require 20+ hours. Solar versions extend runtime significantly in sunny conditions.

Navigation Features

Full-color maps with turn-by-turn navigation matter for exploration and unfamiliar routes. Breadcrumb navigation (showing your route as a line) works for following pre-planned routes on familiar terrain. Consider how often you ride somewhere new.

Training Analytics

Garmin leads in on-device training analysis with Training Status, Recovery Time, and suggested workouts. If you use a coach or TrainingPeaks, you may not need these features—simpler computers that just record your ride work fine.

Sensor Compatibility

All computers we recommend support ANT+ and Bluetooth for connecting power meters, heart rate monitors, and speed/cadence sensors. Make sure your existing sensors will work with any computer you choose.

Ecosystem

Consider what you already use. Garmin computers work best with Garmin sensors, watches, and Garmin Connect. Wahoo integrates seamlessly with Wahoo trainers. Hammerhead is platform-agnostic but has a smaller accessory ecosystem.
