Over the last few years, I’ve tested most flagship bike computers: Garmin Edge 1040, Edge 1050, Hammerhead Karoo 3, Wahoo ELEMNT BOLT 2, and many more. Surprisingly, except for software updates, we haven’t seen a new head unit from Wahoo for several years. But it’s finally here. It’s called Wahoo ELEMNT Ace, and I was the first person to use it in Czechia. I bought it for my own money, and in this early review, I share my thoughts on it.

Wahoo ELEMNT Ace: Pros & Cons

These are the main pros and cons of the Wahoo ELEMNT Ace that I discovered during use.

Unboxing and Initial Setup

The ELEMNT Ace’s initial setup is straightforward. You simply scan the QR code using the Wahoo app, connect it to WiFi, and it updates itself. What disappointed me was that I had to set up my data pages again. They were not synchronized with my previous bike computers from Wahoo. Garmin is pretty good at this; they synchronize everything from the cloud.

My Experience with Wahoo ELEMNT Ace

Below, I share my early experience with ELEMNT Ace in the most important areas. I will update this review once I gather more information.

Display

The 3.8-inch display is one of the largest of all bike computers. Only the Jespr bike computer is larger (4 inches). This has several benefits, like better readability and a larger battery, but also negatives, like higher weight. See the following chart, which shows the display sizes of the best bike computers.

The screen is a bit flashier than previous ELEMNT bike computers, but it is still good to read in different scenarios (some of them are below).

The screen resolution is 480×720px, which means it’s also one of the sharpest displays, similar to Hammerhead Karoo 3 or Garmin Edge 1050. See the following closeup picture.

The following picture shows multiple popular bike computers. Hammerhead Karoo 3 is the brightest, followed by Edge 1040 and the rest. Ace has roughly the same brightness as BOLT 2 and ROAM.

Thanks to the large screen, Ace can show up to 11 data fields, which are super easy to read. Unfortunately, the way the data fields are shown is pretty traditional and not too graphical. There are also no data field previews like on the Edge 1050 and Karoo 3.

On the other hand, some details, like the background color of the gradient depending on the actual gradient or watt and HR zones, are pretty cool.

By the way, below, I add a few comparison pictures with Wahoo ELEMNT BOLT v2.

Battery Life

Wahoo, the ELEMNT Ace has a claimed battery life of 30 hours. The real battery life lags far behind the supposed one. Thanks to my friend who rides outside even in winter, we found out the real battery life is only around 16 hours. This makes it basically the same as the battery life of the ELEMNT BOLT 2 and ROAM 2. This is a great disappointment.

Of course, several sensors were connected to the bike computer, such as a bicycle radar, power meter, and heart rate monitor. Ace was used on auto brightness (yes, Ace has an ambient sensor to adjust the brightness).

Of course, Ace has a USB-C charging port. I think I will stop mentioning this feature in 2025, as it has become a standard. In the EU, it’s mandatory for electronic devices, effective from the 28th of December 2024.

Control & User Friendliness

If there was something I had high expectations of, it was the ease of use ELEMNT computers are known for. Ace’s system is more comprehensive but still not too complicated. You intuitively know where you find the things you are looking for. However, if you expect the same simplicity as with BOLT and ROAM, I will disappoint you. The touchscreen and the menus suited for it add an extra layer of complexity.

Many settings, including data pages and data fields, are set via the smartphone app. I like this solution, but if the head unit has a touchscreen, it should also have the option of setting it on-device. This is something Ace doesn’t have. Maybe Wahoo wanted to keep things simple.

As always, I tested the display’s controllability with gloves and when wet. Ace’s display performed below expectations. Unlike Garmin bike computers, it struggled when wet, and it was not as accurate, especially when I had gloves and the screen was wet. Without gloves, but when wet, its accuracy increases. Watch the following video for further reference.

You can control Ace with the touchscreen or buttons. Both approaches work pretty well. Buttons are helpful in winter or rain. You can use them instead of trying to hit the exact spot on the screen with gloves. However, I have to say that the side buttons are not as tactile. This is an issue when using gloves. The three front ones are fine, but the side ones could be better.

I’ve only been using Ace for a few days, so I can’t rate its long-term reliability. However, I haven’t encountered any bugs or issues. Based on my experience with Wahoo bike computers, I believe it will be better than Garmin’s.

Maps & Navigation

ELEMNT Ace has great maps. They are not on the level of Karoo 3 (those are almost like on a smartphone), but they are easy to follow. So, how good is the actual navigation? I don’t have the answer now since I haven’t had a chance to test it properly yet. I tried a few easier routes, and the calculated ones were okay. I will update this part once I spend more time with Ace.

Browsing maps on Ace is not as smooth as on Hammerhead Karoo 3. It’s a bit laggier, but it’s nothing super annoying. You can pinch to zoom in or out and swipe with two fingers to switch between 2D and 3D views. It’s pretty cool. Watch the following video.

Route calculation of uploaded routes works almost instantaneously, which is great.

Free Summit Feature

The Free Summit feature is slowly becoming one of my favorite things about Ace. It’s similar to Garmin’s ClimbPro and doesn’t require a planned route. It estimates the path you will take and shows the climb data (gradients, distance to the top, etc.) so you can pace yourself better.

You can achieve better accuracy for planned routes, but even the free rides are good enough. Where Summit wins is its customizability, though. You can use the smartphone app to change the data fields for the Summit page, which is absolutely awesome. But you can also change how the Summit behaves.

For example, it can only be turned on when you are also using navigation. This makes sense; I don’t need the Summit to be turned on in my area, where I know all the climbs. You can also set what climb difficulty it will appear for or whether your data pages will automatically change to the Summit page.

Check out my comparison of Free Summit vs. ClimbPro for more details.

GPS Accuracy

The ELEMNT Ace supports multi-band GNSS. I compared its accuracy with other bike computers on my favorite forest segment. I expected better accuracy. You can see from the screenshots below that Ace didn’t nail my position. You can see when I started zig-zagging, but still, it’s not super accurate.

However, I consider a bigger problem to be the very slow search for satellites. It takes Ace up to several tens of seconds. Sure, they load during the ride and we’re talking about minor inaccuracies, but I would expect a much faster load time for a flagship unit.

Connectivity

The ELEMNT Ace has Bluetooth, Wi-Fi, and ANT+ connectivity, so it can be used with most sensors. It automatically syncs rides, as is standard on high-end head units.

Air Sensor

I expected the most from Air Sensor. Unfortunately, I am disappointed. I can see the wind speed while riding, but honestly, this metric is completely useless to me. The same can be said for the time breakdown in the various “zones” offered by the Wahoo app. The data is interesting but actually useless, or I just haven’t found a use case for it.

Speaker, Electronic Bell, and Voice Commands

Many people (including me) laughed at Garmin when they introduced the electronic bell to their Edge 1050. A few months later, here we are, and other manufacturers started to copy this idea. The bell is useful, and Wahoo’s implementation is much cleverer. You just double-tap the screen, and it honks. You don’t have to tap the screen and then press the bell icon like on Garmin. Some people (GP Lama) already found a way how to adjust the sound.

I also like the idea of having voice instructions on when to turn so I don’t have to take my eyes off the roads and stay aware of what’s happening around me. However, you first have to turn them on in settings. I think they should be turned on by default, but okay. They are also pretty loud, so it’s highly possible you will turn them off right away to avoid annoying your friends.

Conclusion

Based on my first impressions, I appreciate that Wahoo pushed their bike computer game forward. I’m sure the Ace took a lot of their time and resources. It’s a decent bike computer that targets a specific group of people. It’s not for me. I don’t like how bulky and heavy it is. I prefer smaller head units. Its size causes mount compatibility issues, so it’s possible it won’t fit your front-out mount.

I also hate the fact that it was released without some marketed features, such as the Strava Live segments, elevation profile, and more. These were added with the 19 December 2024 firmware update. This shouldn’t happen, and features should be available at launch. As Markus Brownlee says: “Never. Ever. Buy a tech product based on the promise of future software updates.”

While I’m already preparing a big comparison with other flagships like the Edge 1050 and Karoo 3, for now, it seems that Ace matches them in the basics. Unfortunately, it doesn’t exceed them in many. The only areas I can think of are the better customizability of the Free Summit data pages and the integrated wind sensor, which provides interesting data, but for me and many others, they are just that, and a larger screen size. And that’s about it. Is it worth it, then? I don’t think so. There are better alternatives.
