I spent money on Edge 550 and BOLT 3, so you don’t have to. I compared them in depth to help you decide whether they are worth it or if you should consider some of their alternatives.

Edge 550 vs. BOLT v3: The Basics

The table below compares the technical specifications of the Garmin Edge 550 and ELEMNT BOLT v3.

Edge 550 vs. ELEMNT BOLT 3: Features Comparison and Differences

Physical Dimensions & Weight

The Edge 550 and ELEMNT BOLT 3 have similar dimensions, but the Edge 550 is wider and heavier by about 36g. I’m not saying this will make a difference between winning or losing a race, but if you are a weight weenie, you should know about this!

They are small to mid-size head units, ideal for most scenarios, and my preferred size. I find the Edge 1050, Wahoo ELEMNT ACE, and similar bike computers too big for casual riding. On the other hand, if you have poor eyesight, you might benefit from the larger head units.

Ease of Setup

To set up both of these bike computers, all you have to do is scan a QR code. If you have already been using a Garmin Edge bike computer, its settings, such as the data pages, data fields, and sensors, will be downloaded from the cloud. Leaving you with a ready-to-go unit. You can also adjust most settings directly on the Edge 550, and eventually, via the Garmin Connect smartphone app.

On BOLT 3, the data pages and data fields are synchronized as well, but you still have to pair the sensors. Additionally, some settings are not available on the head unit, and you must use the Wahoo smartphone app. These include changing the data pages and data fields, and a few more.

I declare the Edge 550 the winner, but it is pretty close here.

Winner: Edge 550

Display

The 2.7″ display size of the Edge 550 is 0.4″ larger than that of the BOLT 3 (2.3″). Does it make a difference? Well, a bit, yes. The fonts on the Edge 550 are slightly larger and easier to read. The resolution is higher on BOLT 3, but it doesn’t make much difference, to be honest.

Both head units are button-based. This is great for controllability in wet or winter conditions, but more on that later. The most significant difference is in readability and brightness. Honestly, the BOLT 3’s display sucks compared to the Edge 550. See the following gallery.

The Edge 550 is a clear winner here. BOLT 3 is simply not bright enough. While it’s readable, it’s harder to read in most scenarios compared to the E550.

Winner: Edge 550

Control & User Friendliness

The ELEMNT BOLT 3 is easier to control, thanks to fewer features and simpler menus. However, it offers fewer on-device settings, making it more smartphone-dependent in case you need to change data fields, for example.

I don’t have any preference regarding the buttons’ placement. I’m fine with both approaches: having them below the display, as on BOLT 3, or at the bottom of the unit, as on the Edge 550. However, if you have a short bike computer mount, you might have trouble accessing the Edge buttons. But this is usually the case with the Edge 10×0 line. The buttons on both devices feel tactile and easy to press.

Garmin Edge bike computers might feel a bit clunky and overwhelming, especially the first time you use them. They have a steeper learning curve because there are so many features and options. With ELEMNT bike computers, it’s much simpler because they have fewer features. However, the UI on the 3rd generation feels a bit clunkier than that on the 2nd.

In summary, you can perform more actions and adjust more settings directly on the E550, but it takes a while to learn where all the options are. BOLT 3 is more limited and more smartphone-dependent, but also simpler. So I’m calling this a draw.

Winner: It’s a draw

Battery Life

The Edge 550 has a claimed battery life of 12 hours. My E550 lasted 10.3 hours in real-world testing. This is not enough in 2025 and beyond. Also, remember that, unlike the E840, the E550 is not available in Solar option.

The BOLT 3 results were more surprising. While the claimed battery life is 25 hours, my BOLT 3 lasted 28 hours, so almost the same as the Edge 840 Solar.

These results mean that you will have to recharge the E550 at least twice as often as the BOLT 3.

I used both bike computers with auto-brightness settings (yes, both have ambient sensors to adjust brightness) and kept the same set of sensors connected to both. Below is a comparison of the claimed battery life with some of the best bike computers. The Edge x40 line was well above average for battery life, but the x50 is below it.

Winner: BOLT 3

Maps & Navigation

This is another area where the Edge 550 has an edge. Its navigation is simply more detailed and provides more granular instructions than BOLT 3. Neither head unit is ideal for navigation, as they don’t have a touchscreen, so browsing maps is a pain. Although Garmin is in a league of its own for navigation, what bothers me is the size of the map regions. Downloading gigabytes of data to update maps for a specific country is unfortunate. Wahoo lets you select countries so that you can complete the update in minutes, for example, before your next vacation.

Winner: Edge 550

Accuracy

Thanks to the Multi-Band GNSS system, which enables simultaneous reception of satellite signals across multiple frequency bands and global systems, both head units are more accurate. This is especially true for BOLT 3, as its predecessors didn’t have this feature. However, this technology alone can’t guarantee the same level of accuracy between two competing devices. So, how was the reality?

I always test bike computers on my favorite forest segment. When you take a look at the following screenshots, you can see that the accuracy is almost identical. However, I must point out that for a completely comparable test, I would have to test both bike computers on the same day. It makes a difference if it is sunny or cloudy.

Winner: It’s a draw

Extras

Both bike computers can display information about upcoming climbs. These features are called ClimbPro (Garmin) and Free Summit (Wahoo) and are some of my favorites. They don’t require a planned route, so I can pace myself more effectively on climbs that I’m not familiar with. I did a comprehensive comparison of these two and Hammerhead’s Climber. In summary, the ClimbPro data page is less customizable than the Free Summit one, so keep this in mind.

Winner: Edge 550

Total score: Garmin Edge 550 (4) | Wahoo ELEMNT BOLT 3 (1) | It’s a draw (2)

Garmin Edge 550 and BOLT 3 Alternatives

If you don’t want a Garmin 550 or BOLT 3, consider these alternatives:

• Hammerhead Karoo 3 offers similar battery life to Edge 550 but features a different, more modern user interface and an even brighter display.
• Garmin Edge 840 is ideal if you want a longer battery life. However, it lacks a bright display and has a bit more limited feature set (e.g., it doesn’t have an in-built speaker).
• Garmin Edge 1050 is larger than Edge 550 and offers the same feature set, but it’s also more expensive.

Summary

After comparing several categories, Edge 550 beats BOLT 3 in most of them, including some of the most critical, such as display readability. It only loses out in battery life, which is a shame because that’s also its biggest downside. The Edge 550 requires frequent charging and may not last for whole-day trips.

The price difference between these two head units is significant. The Edge 550 costs $499 while the BOLT 3 “only” $349. Is the $150 difference worth it? I believe so. E550 offers so much more than BOLT. BOLT might surpass the Edge in simplicity, but at the cost of a limited feature set.

Before pulling the trigger, consider whether you’re okay with previous generations, such as the Edge 840, which lasts twice as long as the Edge 550. Yes, it doesn’t have as many features, but it does most of the things well.

Anyway, I hope you will find this comparison helpful. If you do, please click the links below. It’s the best way to support me and my website without additional costs. Thank you very much in advance!
