I bought all the Garmin Edge x50 bike computers, including the Edge 850 and Edge 1050, to find out whether they are worth it. I’ve been putting the Edge 850 through its paces for a fair few months now, across varied terrains on Gran Canaria and back home. I compared it with previous generations and some competing bike computers, covering everything from daily commutes to long mountain rides.

So, should you buy it? The answer is not very clear-cut. But after reading this review, you will know exactly if it’s the right fit for you.

NOTE: I tested the Edge 850 with firmware version 7.10.

What’s New Compared to the Edge 840?

Unboxing and Initial Setup

If there is anything I like about Garmin Edge devices, it’s how they guide you through the initial setup. It’s super convenient, especially if you previously owned an Edge. After scanning the QR code and following a few steps, they will transfer all your data pages and sensors, so you don’t have to pair them as you do with some competing head units. For comparison, Wahoo ELEMNT bike computers can also sync data pages, but not sensors.

Naturally, the user interface is unified with the other x50 head units, such as the Edge 550 and Edge 1050. It’s a bit more polished than the one on the x40 line.

My Experience with Garmin Edge 850

Below, I go through the individual features in more detail.

Display

Garmin increased the display size by 0.1″, bringing it to 2.7 inches. It now uses transmissive LCD on its x50 head units, so they are much brighter and easier to read in most scenarios (see the gallery below).

The pixels per inch (PPI) are lower than on the Wahoo ELEMNT ROAM 3 (271 vs. 309 PPI), for example, but everything looks sharp, and I can’t tell the difference

The 0.1″ size difference compared to the previous generation and the ROAM 3 is negligible. I think this display size is ideal for most use cases, as it’s suitable for navigation but not too big for daily riding. The following chart shows the display sizes of other popular bike computers.

The display is now bright enough to be easier to read even in direct sunlight. However, it’s tricky to capture it on camera. I would say that the screen is almost as bright as some of today’s smartphones. So, that’s pretty cool. Of course, the screen brightness appears differently depending on the bike computer’s tilt (as seen in the photos below). Keep in mind that the screen surface is glossy, so it still reflects glare.

The glossy screens are the only thing that drags the Edge bike computers down a bit, in my opinion. If they have an anti-glare coating like the Wahoo ELEMNTs second gen, that would be great.

The photo below shows another comparison, this time with other popular bike computers. In reality, Hammerhead Karoo 3 is the brightest, with Karoo 2 and Magene C606 closely behind. BOLT 3 and ROAM 3 are the least bright.

The Edge 850 can display up to 10 data fields at once, keeping them relatively easy to read, though they are naturally a bit smaller than on the 10×0 models (those can also display up to 10 data fields).

Battery Life

The Garmin Edge 850 has a dramatically worse battery life than the previous generation and most other bike computers on the market. It should last up to 12 hours, but the real battery life is lower. I squeezed only 10.3 hours from it¹.

This is bad. You might be worried about not being able to record your whole-day trips as I did on Gran Canaria. For comparison, the following chart shows the claimed battery life of the best bike computers on the market.

The horribly short battery life is one of the main reasons I won’t use this bike computer as a daily driver, and I will most likely return to the Edge 840, Edge 1050, or Wahoo ELEMNT ROAM 3. I’m not fully decided yet (reviewers’ problems, haha).

To be fair, Garmin’s 12 hours is not a light-use number. On Garmin’s battery life page, it is a “demanding use” figure. It assumes multi-band GNSS, four ANT+ sensors, and a connected phone with LiveTrack. It also assumes auto brightness, the map page on screen, following a course, and 10 to 40°C (50 to 104°F). Garmin adds that a Varia radar can reduce battery life further. My test included a Varia RTL515 radar, so getting less than 12 hours is not a big surprise.

If you need more from a single charge, there is a battery saver mode. It is a setting that cuts back on features to make the battery last longer. Garmin claims up to 36 hours in battery saver, but that figure assumes GPS only, two sensors, and a 15-second backlight timeout. I see it as an “emergency” feature, not an option for day-to-day use.

There are two other ways to stretch the battery. The first is lower brightness. In DC Rainmaker’s review, a fixed 30% brightness roughly doubled the battery life to about 20 hours in his test. The catch, according to DC Rainmaker, is that the screen struggles in direct summer sun at that setting. The second is charging on the go. According to Garmin’s specs, the Edge 850 supports in-ride charging with the Power Mount and Charge battery pack (sold separately). Garmin’s firmware 30.18 (February 2026) also improved the battery estimates in Auto GNSS mode. I charge it every 2 to 3 rides, depending on the length.

Control & User Friendliness

The new user interface on x50 line is better than the one on x40. Thanks to the Edge 850’s touchscreen and control buttons, it’s super easy to use in all scenarios (even with gloves, as you can see in the video below). Just remember that, given the sheer number of features, Edge bike computers have a steeper learning curve. It took me a while to remember where all the options and settings are, and I am sure I still don’t know everything.

I’ve heard so many times that a touchscreen is not necessary, and I agree, especially since all you do is record your activities, and you pair the Edge with Di2 or SRAM buttons so you can scroll through pages. However, once you start using the maps and navigation, it’s a different story, and I recommend paying more for the touchscreen. It’s much easier to browse the map on it than on the Edge 550.

Finally, I would like to highlight the new chassis design, which makes repairs and battery replacement easier. This is based on EU legislation on the Right to Repair. In addition to being able to remove the entire back side, you can also replace the plastic socket in case it breaks.

Maps & Navigation

The Edge 850 has improved maps and navigation. They are easier to follow because the roads, trails, and other features have more distinct lines and contrast.

The Edge 850 can navigate you almost anywhere. I relied heavily on its navigation in Gran Canaria. There are lots of roundabouts there, so it’s cool that the head unit shows you exactly how to enter and exit them.

Unlike the Edge 550, the Edge 850 also includes address search and an on-device course creator. This means you can plan a route directly on the device, whether it’s a linear path to a point of interest or a round-trip course from your current location. This is handy when exploring unfamiliar areas. It can also provide audible alerts via the built-in speaker.

I tested navigation mainly on paved roads, and it worked flawlessly. Garmin has one of the best maps, including off-road coverage. You can also install third-party apps, such as TrailForks, to explore trails and more.

Thanks to the touchscreen, browsing maps is also convenient, unlike on the Edge 550. If you are a frequent map user, the Edge 850 is worth considering, especially given these solid on-device route-planning tools. The only drawback is that the screen is smaller than on the Edge 1050, which simply displays more information.

GPS Accuracy

Thanks to the multi-band GNSS, the Edge 850 is one of the most accurate bike computers. When I test its accuracy, I ride a specific segment in the forest, record my ride, and then compare the recorded route with the actual route and my previous tests.

I tested the Multi-GNSS Multi-band system because it’s the most accurate. The accuracy is so good that the ride recording accurately tracks the side of the narrow forest road I’m riding on. On the other hand, it drains more battery. Take a look at the following screenshots for further reference.

ClimbPro

ClimbPro is one of the most useful features, especially for people like me who love climbing. We can now slightly customize the data page and use a customizable number of data fields. However, it’s still much more limited than the adjustability of the Free Summit feature on Wahoo bike computers. It’s a shame that there are no data fields, such as “Average power during this climb.” That would be very useful. However, you can work around this using the Avg. power (lap) field. You just have to start a lap before each climb.

Despite these shortcomings, the ClimbPro inspired other manufacturers, and the overall quality of these features is slowly improving.

Real-Time Stamina, Power Guide, and Smart Fueling

Thanks to Real-Time Stamina, you will see how long you can ride at the current pace and how much you have left in the tank. Power Guide suggests the power zones for your planned route based on your FTP. These features can now account for additional metrics, such as route elevation, weather, user profile, and even your acclimation. As a result, they are more accurate.

For example, when using Power Guide, it will account for your Stamina and wind data. This means that if you ride into a headwind or your Stamina drops faster than expected, the Power Guide will adjust the target power zones. I appreciate this improvement. It makes me excited to see what other metrics Garmin adds in the future to improve the accuracy even further.

Smart fueling is new on the x50 line. It reminds you when to eat and drink during a ride. According to Garmin, it estimates your needs from your fitness, the course demands, heat, and humidity. As mentioned above, it works with a power guide or a workout, and it needs a power meter and heart rate monitor.

At launch, DC Rainmaker found the suggested nutrition far too low for a hot 40 km (25 mi) gravel ride. Garmin’s firmware 30.18 (February 2026) fixed nutrition recommendations on courses under two hours. Garmin doesn’t say whether that covers cases like his.

After the ride, Gear Ratio Analysis shows how you used your gears, as long as you have an electronic groupset.

Mountain Bike Features

This section is based on Garmin’s specs, not my own testing. As I mentioned above, I tested navigation mainly on paved roads. According to Garmin, the enduro and downhill profiles record GPS at 5 Hz while you descend. There are also timing gates (start and finish points you set to time your own sections), MTB Dynamics, and incident detection that works off-road. You can add Trailforks too. Firmware 32.20 (August 2026) added automatic climb and descent detection for the Enduro and E-Enduro profiles.

Shared Road Hazards

Sharing road hazards, like Waze or Google Maps, is a great feature. The more people use it, the more useful it becomes. It might take a while before enough people in some areas are in the Garmin ecosystem and contribute by adding these hazards. Fortunately, Garmin made this feature available for the x40 head units some time ago to widen the user base. This is another example of the benefits of the Garmin ecosystem.

GroupRide, Challenges, and Awards

GroupRide has received several improvements. For example, one improvement is that if the Edge 850 detects a crash, it notifies others in the group (when GroupRide is on). This is an excellent feature, and I am surprised we didn’t get it sooner. Imagine how useful this feature will be during fast descents. Another handy addition is the ‘You vs Group’ comparison, which shows rolling 5-minute averages for metrics like your HR, power, cadence, speed, and W/kg against the group. This is a pretty solid way to keep tabs on how you’re stacking up during a group ride.

The Challenges are similar to Strava live segments. You can compete with your friends to see who can climb the upcoming climbs the fastest. Currently, this feature only works for climbs in ClimbPro. This is Garmin’s way of giving you another reason to choose the Garmin bike computer and lock you into their ecosystem.

And the Awards are just Garmin’s way of leveraging additional gamification elements. You earn rewards for your power output, speed, and more. These are just some examples of how Garmin tries to lock people into its ecosystem.

Connectivity

There are no connectivity changes. The Edge 850 still supports Bluetooth, Wi-Fi, and ANT+ connectivity, so you can connect it to sensors or your smartphone. Of course, it can auto-sync activities, courses, etc. I sometimes experienced longer sync times for activities over Wi-Fi in the Canary Islands, but at home, it worked fine. I suspect the Wi-Fi settings may have been a factor.

Note that Garmin fixed slow syncing over Wi-Fi in firmware 31.29 (May 2026). My observation predates that update.

Firmware Updates Since My Test

I tested the Edge 850 on firmware 7.10. As of September 30, 2026, the current public version is 32.20 (August 2026). Below are the changes that matter most for riders, based on [Garmin’s Edge 850 software page](https://support.garmin.com/en-US/?partNumber=010-03023-00&tab=software). I left out beta versions.

• 7.09 (September 2025): support for Garmin Rally 110/210 power meter pedals, plus touchscreen and auto backlight improvements.

• 7.10 (September 2025): Auto became the default GNSS mode. For my GPS test, I used the Multi-GNSS Multi-band setting.

• 29.22 (November 2025): double-tap bell shortcut, cycling safety voice alerts, GroupRide real-time averages, shareable timing gates, a cycling ability history graph, and a fix for audio prompts that always played in English.

• 30.18 (February 2026): provisional finish point, estimated time to completion for free climbs, a three-field map layout, better battery estimates in Auto GNSS mode, a fix for the 0% brightness slider, and a fix for nutrition recommendations on courses under two hours.

• 31.29 (May 2026): Bosch smart system eBike support, gear tracking, a radar screen that follows the color mode, ClimbPro and navigation fixes, and a fix for slow Wi-Fi syncing.

• 31.33 (July 2026): a fix for GPS signal drops.

• 32.20 (August 2026): automatic climb and descent detection for Enduro and E-Enduro, an improved Stamina model, a Shimano 1x Di2 time-in-gear fix, a RearVue 820 pairing fix, ClimbPro fixes, and a fix for a crash during long recordings in battery saver mode.

Garmin’s battery claims haven’t changed since launch, and neither has the US price. Those were my two main complaints, so my verdict below stays the same.

My Verdict

There are two main things I dislike about the Garmin Edge 850: its short battery life, which requires recharging about twice as often as the Edge 840, and its price. I absolutely hate this trend of raising prices so much year over year. It’s not sustainable. The Edge 850 is probably one of the most capable bike computers of this size, but earlier generations perform nearly as well.

So, if you don’t care about the latest and greatest features, consider buying the Edge 840 instead. You will get twice the battery life and save several hundred dollars. If you decide to purchase the E850 anyway, please use the links below. It’s the best way to support this website, and it won’t cost you anything extra. Thank you in advance.
