The Garmin Edge x50 lineup is now complete, with the introduction of the Edge 550 and the Edge 850. Below, I summarize the differences and explain the new features compared to the previous generation.

The Differences Between the Garmin Edge 550 and 850

The table below shows the technical specifications of the Garmin Edge x50 lineup.

The Edge 550 is button-based, lacks a speaker/voice prompts, and does not support Garmin Pay or on-device course creation.

The Edge 850 adds a touchscreen, speaker, bike bell, voice navigation, Garmin Pay, on-device route creation, and more storage (32 vs. 64 GB). It also comes with preloaded maps for two regions, while the 550 has one (you can download other regions for free). It closely resembles the Edge 1050 in features (but with a smaller display and lower battery life).

All models use the same fast, bright transmissive LCD, which improves visibility but reduces battery life compared to older transflective screens. The battery life was absolutely slaughtered compared to the Edge x40 line. Take a look at the following chart, which compares Garmin Edge units from the past few years.

The Edge 550 and 850 won’t last half as long as the Edge 540 and 840. Yes, you can use the battery saver mode (Garmin claims up to 36 hours), but it limits accuracy, dims the display, and other functions. It’s not an option for day-to-day use but rather an “emergency” feature.

DC Rainmaker found a middle ground. With the brightness fixed at 30%, the battery life of his Edge 850 roughly doubled to about 20 hours. The catch is that the screen was hard to read in direct sunlight.

What’s New with the Edge 540 and Edge 840?

The Garmin Edge 550 and 850 represent a clear generational leap over the Edge 540 and 840, bringing a new display, updated design, and expanded features. But it comes at the cost of battery life and the loss of the solar charging option.

• New Display Technology: Both the Edge 550 and 850 replace the older transflective screen (high battery efficiency, but dimmer colors and lower contrast) with a significantly brighter transmissive LCD like the Edge 1050. This improves visibility in most conditions but reduces battery life dramatically compared to the Edge 540 and 840.
• Larger Display: The Edge 550 and 850 now feature a 2.7” display (up from 2.6”).
• Design Refresh: The new devices are “taller” (92.2 mm vs. 85.1 mm) and heavier (110 g and 113 g vs. 80.3 g and 84.8 g) to accommodate bigger batteries for the more power-hungry screen. They are actually a bit thinner, though: 16.8 mm vs. 19.6 mm.
• No Solar Option: The x50 models have dropped the solar charging feature that was a highlight of the previous generation.
• Speaker, Electronic Bike Bell, and Voice Navigation: The Edge 850 now includes a speaker for spoken turn-by-turn instructions, an electronic bell, and audible alerts. The 550 still relies on a simple beep. With firmware 29.22 (November 2025), Garmin added a double-tap shortcut for the bell and cycling safety voice alerts. Both need the speaker, so they work on the 850 only.
• Garmin Pay: The Edge 850 supports contactless payments, a feature previously exclusive to the Edge 1050 and not available on the 840.
• On-Device Route Creator: Both the 850 and the 1050 let you create and edit routes directly on the device, while the 550 still requires Garmin Connect.
• 5 Hz GPS/GNSS Recording: Faster position sampling (5 times per second) gives more accurate tracks on technical descents. It works only with the enduro and downhill ride profiles. Standard recording stays at 1 Hz.
• Real-time Weather Updates: The Edge 550 and 850 can provide you with weather updates, allowing you to adjust your route to avoid unpleasant situations, such as being caught off guard by rain.
• Timing Gates: You can now set timing gates to track split times.
• Improved Processor and Storage: The Edge 550 and 850 now run on faster processors, have expanded flash memory (Edge 550 up to 32 GB, Edge 850 64 GB), and offer snappier map redraw and overall operation.
• Enhanced Training Features: Garmin’s Cycle Coach, Power Guidance, and “Smart Fueling” have been upgraded to provide more contextual guidance, calibrating nutrition and pacing based on route elevation, weather, and user profile.
• GroupRide and More POI: New features for group rides and additional points of interest, as well as improved map layers and weather widgets.
• Battery Life Downgrade: The battery life is significantly reduced due to the new screen. Garmin claims up to 26 hours for the non-solar Edge 540 and 840. In my tests, the Edge 840 lasted 24.2 hours and the Edge 540 Solar 27.5 hours. The new Edge 550 and 850 are rated for just 12 hours.
• Battery Replacements: Due to pressure from the European Union, Garmin adjusted the device’s design to allow easier battery replacements.

Garmin Edge x50 Alternatives

If I didn’t want a Garmin E550 or E850, I would consider the following alternatives:

The first alternative is the Hammerhead Karoo 3, which offers better battery life but a more limited feature set. Hammerhead now sells it simply as the Karoo, for $525 at the SRAM shop. It also has an entirely different user interface, which I like, and a similarly good display. You can find out more in my Karoo 3 review.

The second alternative is the new Wahoo ELEMNT BOLT 3 and ROAM 3 models, which have twice the battery life but a less bright display and offer far fewer features.  Wahoo claims about 20 hours for the BOLT 3 and 25 hours for the ROAM 3. So only the ROAM 3 roughly doubles the x50’s 12 hours. In my opinion, the ROAM 3 offers better value than the BOLT 3.

And the third worthy alternative is, of course, the previous generation Edge x40 series, specifically the Edge 540, Edge 840, and Edge 1040. Their main advantage is more than double the battery life. Personally, I would choose the Edge 840.

Summary

I think for most cyclists, the extra $100 for the Edge 850 is justified by the touchscreen and electronic bell alone ($599.99 vs. $499.99). Browsing maps on a device and controlling it is significantly easier with a touchscreen. And the electronic bell is more useful than it may seem (I tried it on the Edge 1050).

However, if long battery life is your priority (and you’re willing to sacrifice screen brightness and some modern features), the previous generation Edge 840 or Edge 1040 remains a better choice. They easily double the real-world battery life of the new x50 models.

The x50 series is best for riders who appreciate display quality and smart features, and don’t mind recharging the bike computer more frequently. You can also consider alternatives like the Hammerhead Karoo 3 or Wahoo ROAM 3, or browse my roundup of the best bike computers on the market.
