Coros Dura 2 Solar Review: The Infinite-Battery Garmin Alternative (And the Detail Everyone Will Miss)

Most people knew the original Coros Dura because it was cheap and had an incredible battery life. Today, the Coros Dura 2 launches and it’s not cheap anymore, but it brings a lot to the table. Among those things is a form factor that is unlike anything else on the market.

Of course, part of me wants to say that form factor doesn’t matter, but come on, let’s be real here—this is pretty cool. The new Coros Dura 2 Solar has a carbon fiber backplate and an anodized aluminum bezel making up what sort of looks like two pieces that stack together. The leading edge is only 5.7mm thick and looks more like a concept bike computer than real life.

It is real, though, and it works because it stacks on top of a rear section that houses a pair of buttons, the USB-C charging port, a speaker, and the solar panel. That solar panel has its own set of pressure-sensitive buttons, meaning they respond to actual physical force rather than just the light electrical touch of your finger like a smartphone screen. You’ll also find the Garmin-compatible quarter-turn mount housed in the rear section, and when you put it all together, it’s genuinely unique and very cool to look at.

The new computer isn’t just a pretty face, though. Coros has been mounting a genuine challenge to Garmin for the last few years, and this latest computer is yet another part of that narrative while also bringing unique features to market. To test it all out, I took off my Garmin watch, strapped on a Coros Pace 4 Pro, put the Garmin Edge 1050 in a drawer, and mounted the Coros Dura 2 Solar on my bars. Here’s what I found out.

What I like about the Coros Dura 2 Solar

There are several pillars I want to discuss regarding the Coros Dura 2 Solar, but the battery life is so far beyond what anyone else is offering that it has to be addressed first. It almost minimizes how much Coros outpaces the competition to merely list battery life as “a feature I like” in our standard Velo review format.

Currently, the longest battery life for a direct competitor is the Garmin Edge 1060, which carries a 20-hour rating for regular use and 60 hours in battery-saver mode. You could also point to the Garmin 1040 Solar and its 180-hour rating, but that comes with heavy caveats. First, it is two generations old, despite still being available. Second, that 180-hour figure requires solar charging and zero paired sensors; use it like a normal computer, and it drops to 45 hours. Both are decent numbers given the next closest option is the Wahoo Elemnt Ace with a claim of up to 30 hours.

Then there’s Coros. The Coros Dura 2 Solar isn’t just knocking it out of the park; this computer is playing a completely different sport. The baseline rating is 120 hours if you drop the GPS to single-band, or 70 hours in the more accurate dual-frequency mode. More importantly, those numbers are calculated without solar charging.

Coros claims—and I have no reason to doubt it—that the solar panel will generate two hours of ride time for every hour spent in direct sun. That means if you operate this like a normal bike computer in 2026, fully connected to sensors and actively navigating, you may never actually have to plug it in. After six hours of riding, all with the backlight turned to 100%, and multiple days sitting indoors—Coros designed the unit to stay in standby rather than powering down completely—my review unit was sitting at 93%. I stopped checking the battery percentage after that.

Focusing exclusively on the battery life does sell the Dura 2 slightly short, however. When the original Dura launched, it felt half-finished and was not a great product. Velo actually published a second first-impressions article when later firmware updates finally made it a reasonable option, but it still lagged behind the competition.

With the launch of the Dura 2, Coros is shedding that legacy. Every manufacturer has advantages and disadvantages, but if you want a reliable head unit in 2026, the Coros Dura 2 is firmly in the “yes, this is a good computer” category. A significant part of that success comes down to the ecosystem.

Because I like to self-coach, performance tracking and recovery metrics are important to me. Garmin has been the king of that space for years with Garmin Connect. However, Garmin operates a walled garden, and the hardware buy-in is expensive. Coros clearly recognized this market opportunity. The Coros Training Hub is every bit as good, and while it is also a walled garden—albeit one that allows Wahoo head units inside—the hardware is significantly cheaper. I am a big fan of the simple recovery status, as well as the implementation of metrics that mirror Joe Friel’s gold-standard CTL, ATL, and TSB models in TrainingPeaks.

A bike computer is just one piece of an overall training ecosystem but this is a solid one. I prefer a single upfront hardware purchase rather than paying recurring subscription fees for training software over time. Coros nails that, and the Dura 2 is a key piece of the puzzle.

The ecosystem isn’t everything though. The Dura 2 also needs to be a capable head unit on the road, and this time around, it absolutely is. Screen setup is dead simple and easily adjustable via the Coros app. Navigation is solid, displaying street names based on your zoom level, and the map screen responds to intuitive smartphone-style swipes and pinch-to-zoom gestures. If you do wander off course, rerouting requires a Bluetooth connection to your smartphone, but it does not require the phone to have active cellular service. It’s also quick even on long routes and  there’s plenty of notification to let you know when turns are coming.

Coros has also righted some wrongs from the past. For riders doing structured workouts outdoors, you can now pause an interval independently from the overall ride recording, and all standard sensor connections work exactly as expected. There was already a climb screen but now it’s simplified and no longer dependent on having a pre-loaded route.

Data presentation is another strong point. I appreciate the color-coded data cells that fill up based on your current effort. Push into a VO2 max interval, and your power cell fills with purple. Drop into a recovery spin, and it empties to a cool blue. It’s reminiscent of Wahoo but it has its own flavor. Other quality-of-life additions, like a sideways swipe to control your phone’s music player, crystal-clear Strava Live Segments, and a built-in speaker that doubles as a digital bike bell, round out the feature set nicely.

And just as I don’t want to ignore the cool aesthetic of the physical design, I also don’t want to understate its practical usefulness. The unit weighs roughly 100 grams and Coros placed the quarter-turn connection point very far back near the base. Because of this design, you are highly unlikely to experience clearance issues on any out-front mount. I would feel completely safe traveling to press events with this computer without knowing what kind of mounts will be available. That is an issue I occasionally run into with the larger Garmin 1050. The low weight also gives me peace of mind when hanging heavy lights underneath. Not everyone runs into these clearance and weight problems, but Coros has done an excellent job ensuring you probably never will.

What I don’t like about the Coros Dura 2 Solar

I highlighted the Coros ecosystem as a strength, but it’s also a vulnerability, and price sits at the center of the issue. At $249, whatever problems the original Dura had received a major pass. The next closest competitor was the Wahoo Elemnt Bolt, but the Dura was still $100 less expensive and more than good enough at everything it did. Now the price has pushed to $500, and that changes the math.

Given the quality of the hardware, it’s reasonable for Coros to ask for that much money, but it also places the Dura 2 into direct competition with incredibly polished computers from Garmin, Wahoo, and Hammerhead. Coros isn’t lacking in any major way, but there are still rough edges. For example, the live ride tracking includes a clever feature that lets you schedule a tracking link to be sent when you plan to ride. However, you can’t set it to automatically broadcast to a designated list of emergency contacts every time you hit start.

That might not be a dealbreaker on its own, but then you run into the lack of third-party integrations. With Strava recently cutting off API interoperability, you now have to rely directly on your bike computer to sync with outside platforms. If you want to use different mapping software like Trailforks, or try something new like the various AI coaching platforms I’ve been testing—like ridewithdave—you will find an API connection for Garmin, but not for Coros.

Ecosystem lock-in is another factor. If you want 24/7 recovery metrics, you need a watch. Coros makes great wearables—I’m currently testing the Coros Pace 4 Pro alongside the Dura 2—and the system works well. But off the bike, I don’t always want to wear a dedicated sports watch. I prefer something more stylish, or maybe you prefer a screenless tracker, and Coros doesn’t offer that. Garmin has a huge range of options that Coros doesn’t really come close to matching.

Then, on the bike, the Dura 2 features a screen that reminds me a lot of the Garmin Edge 1040 Solar. To be fair, the processor is faster than that older Garmin, but the display is still quite dark and relatively low resolution at 201ppi. I cranked the backlight all the way up because it can be difficult to read if you shade the screen with your body during a ride. Unfortunately, it doesn’t really work. The panel has a highly reflective, e-ink quality that looks fantastic in direct sunlight or in the dark, but struggles in mixed, shaded lighting. The maps look good enough at this resolution, but I also know that the screens on modern Garmin and Hammerhead units look significantly better.

None of this mattered when the computer was cheap. At $500, though, the value proposition gets murky. Garmin hasn’t done themselves any favors by launching an $800 Edge 1060 as I write this, but the Edge 1050 is still widely available at $700. Obviously, $200 is a real price gap, but we are also heading into the holiday season. The Edge 1050 frequently goes on sale for $600. At that price, you have to stop and think. The Garmin ecosystem is incredibly polished and widely supported. Are you willing to accept something that’s very good, but not perfect, for a savings of just $100?

Livability

For the most part, livability is a high point. I’ve already discussed how the low weight and solar charging make for a better day-to-day experience, but one detail I haven’t gotten deep into is the physical button situation.

The Coros Dura 2 is a touchscreen system, which can inherently cause issues. There is no way to manually lock the screen—a feature I often use on Garmin computers—but Coros claims the software will auto-lock in heavy moisture situations and is generally good at shrugging off water. We will have to see how it actually handles deep Oregon winter rain, but I did notice that heavy sweat drops didn’t cause any errant scrolling during my testing.

If screen issues do arise, Coros has hedged against them. The buttons located on the solar panel aren’t actually capacitive touch buttons. While they feel similar in use, they rely on physical pressure rather than the completion of an electrical circuit. You can use those inputs, along with the physical side buttons, to fully navigate the interface without ever relying on the touchscreen.

Who is the Coros Dura 2 Solar for?

The easy and simple answer is anyone who envisions doing rides longer than 20 hours without the possibility of charging. That could be a single epic ride or a multi-day bikepacking trip, but that 20-hour cutoff is the practical limit for the Garmin Edge 1060 and 1050—currently the longest-lasting competitors before resorting to a battery-saver mode. If you regularly expect to bump up against that limit, the Coros Dura 2 is a better choice. You might also make that choice simply because you never want to deal with charging your bike computer again.

As I mentioned earlier, though, that framing actually sells the Dura 2 a bit short. There is more to the Coros ecosystem, and even if you don’t need crazy-long battery life, many people will actually prefer the Coros Training Hub to Garmin Connect. Right now, I am looking at Garmin Connect, which tells me my training readiness is “high” while my training status is “recovery” (it doesn’t have all my recent data since I’ve been testing Coros, but you get the idea). Meanwhile, Coros simply shows that I am 90% recovered with an intuitive slider sitting between green and blue. I know which of those is easier to digest at a glance, and it isn’t Garmin. If you are happy relying strictly on major platforms like Strava and you like the watch options Coros offers, the Dura 2 is a rock-solid choice.

Another interesting consideration is the Wahoo integration. This is a Dura 2 review, but if you love the Coros ecosystem but aren’t stoked about the Dura’s screen—and don’t strictly need the infinite battery—you could choose a Wahoo head unit, pair it with a Coros watch, and still use the Coros Training Hub. Part of me worries that connection might disappear in the future, but no one has indicated it will, and it’s great to have hardware flexibility.

On the other hand, if you value screen quality and software polish above all else, choose Garmin. You will likely pay a bit more and get significantly less battery life, but you gain the immense polish of a mature ecosystem alongside a massive catalog of wearable options. The screen is worlds better, and you get access to quality-of-life perks like Garmin Pay for coffee shop stops and native social features that connect seamlessly with other Garmin users.
