The battery life on the Coros Dura is absurdly good. With sun on the handlebars, you forget the computer even has a battery. The software, in my opinion, still has room to grow. But the battery alone is a reason to look at this thing.
I wasn’t looking for a new bike computer.
My current computer is good. Really good. Clean UI, logical controls, reliable. I have no reason to switch. But when the Coros Dura came out, one question got me curious: Can something do better? Hardware and software? Can a different device improve on what mine already does well?
120 hours of battery life. Plus solar. For someone who likes to ride long, that doesn’t sound like a feature. It sounds like freedom. So: time to test.
The battery. The argument.
Let’s start with what the Dura does really well. Coros promises 120 hours of battery life on a single charge. Plus a solar panel that adds up to two hours of ride time for every hour in direct sunlight. Sounds like marketing. But it isn’t. Or at least not only.
In practice, this means: In good weather, you never have to charge the device. It just lives on your handlebars. You wake up, ride, the thing records, you stop. Next day, same thing. No cable, no charger, no “damn, forgot to plug it in”. It fundamentally changes how you relate to your computer.
For ultra distances and bikepacking, this is a genuine game-changer. No power bank on the bars, no battery management on the route. Just ride.
The software: work in progress
Now for the honest part. The Dura is Coros’ first bike computer. And you can tell. Not in a “it’s bad” kind of way, more in a “there’s room to grow” kind of way.
The menu takes some getting used to. You scroll, press, end up somewhere, want to go back, but the screen jumps to the default view as soon as a notification comes in. That breaks the flow, especially mid-ride when you had a specific data page in view.
The interface feels more functional than designed. You can tell engineers built it. Everything is there, everything works. But it’s missing that “this feels right” quality you get from some other devices.
Display and maps
The map graphics could be more legible. Roads lack contrast, and the map rendering is a bit rough compared to others. You can see the route, but details get lost. And if you rely on cue points for navigation, you’ll notice they take up quite a bit of screen real estate.
The display response time could also be faster. There’s a noticeable lag when switching between screens. Not a dealbreaker, but you notice it. The touchscreen is better for tapping than scrolling. The scroll wheel works more reliably, especially with gloves.
Backlight on max does deliver good visibility though, even in bright sunlight. That works.
What works really well
GPX transfer: Loading and syncing routes is fast and smooth. Whether through the Coros app, Komoot, Ride with GPS, or a direct GPX import. One of the most seamless workflows I’ve experienced on a bike computer.
Alerts: Notifications during the ride are clear, easy to see, and don’t overstay their welcome.
Route sync: Fast, reliable, no waiting around. Pick a route in the app, sync it, go ride.
Activity summary: After every ride you get a rating and a clean summary. Sounds trivial, but it wraps up the session nicely. You immediately see remaining battery and how much the solar panel contributed.
Always-on standby: The Dura is always ready. Press a button, start an activity. No boot-up, no waiting. The device simply lives on your handlebars. Very pleasant.
Split screen: nice idea, don’t need it
Coros offers a split screen mode: map on top, data below. The idea is good, but on the small display it gets tight. I personally prefer combining full-screen data pages with the map view by scrolling. Gives me more clarity per screen.
Climb pages: there, but a bit hidden
The Dura automatically detects climbs on loaded routes. Colour-coded by gradient, with distance and average grade. The feature exists and works well. But: it only appears when you’ve loaded a route with navigation. No route, no climb data. You’ll find the setup under Navigation, then select your route, then “Climb”. Not immediately intuitive, but worth exploring.
L/R power balance: delivered later
When I first tested the Dura, left/right power balance from my power meter wasn’t available. Coros has since added it via a firmware update. The Dura now shows L/R balance when connected to a dual-sided power meter. Whether the data exports cleanly to third-party platforms is something I still need to check more closely. What stands out though: Coros delivers regular updates and the device gets noticeably better with each version!
Who is the Dura for?
If you’re into bikepacking, ultra riding, or simply tired of constantly charging your bike computer, the Dura is hard to ignore. You get a solid computer with the best battery on the market. That’s a fact.
If you expect a refined, meticulously designed interface, you’ll need to adjust. The Dura is a tool for people who need few things, but need them reliably. The elegance will surely come, the foundation is already there.
My conclusion
I’ve been riding the Dura for several weeks and I’m honestly impressed by the battery. Not having to think about charge levels changes your relationship with the device. The GPX transfer is excellent, the alerts work, and the thing is simply always ready.
Coros is welcome to keep refining the software. More design sensibility, smoother menus, better map legibility. The potential is there. The Dura is built for endurance, in the best sense. It lasts forever. And it gets a little better with every update.
