5. Garmin Edge 840 Solar

The Garmin Edge 840 Solar is a cycling computer that combines a range of practical features within a compact design. Boasting an impressive touchscreen, the addition of buttons is a welcomed touch for users who cycle with gloves on.

Efficiently performing the fundamental functions of a cycling computer, the device swiftly connects to satellites and bike sensors, ensuring you can focus on your ride.

With the inclusion of GNSS (Global Navigation Satellite System) connectivity, GPS data accuracy reaches new heights. Innovative features like Climb Pro 2.0, Climb Explore, and music controls enhance the overall user experience.

Maintaining the sleek design of its predecessor, the Edge 840 Solar is slightly longer and thicker, striking a perfect balance between screen size and a compact handlebar feel at 57.8×85.1×19.6mm and 88.9g.

Notable features such as ClimbPro, which profiles climbs longer than 500 meters and steeper than a 3 percent grade, contribute to its impressive functionality.

The Edge 840 Solar comes in two versions – one with solar panels and one without. While the solar functionality can extend battery life on sunny days, the added cost may not be justified for those in frequently cloudy locations.


Despite its efficiency, the £70/$50 extra for solar charging may not significantly boost battery life in less sunny regions. Unless you consistently ride in sunny weather, the standard version with USB-C charging provides sufficient power for most users.

The Garmin Edge 840 Solar offers an outstanding combination of features in a compact device, making it one of the best bike computers available.

6. Hammerhead Karoo 2

The Hammerhead Karoo 2, although not immediately synonymous with bike computer excellence, proves to be a compelling contender in a field dominated by giants like Wahoo and Garmin. With a forward-thinking approach, the Karoo 2 offers a refreshingly smartphone-esque experience while delivering a suite of features that are nothing short of impressive.

Measuring 100.6×60.8×19.3mm and weighing 132g, the Karoo 2 embodies a compact yet substantial unit, surpassing rivals like the Wahoo Elemnt Roam in size, thanks to its larger, high-resolution 3.2-inch touchscreen boasting 480×800 pixels. Unlike its counterparts, the Karoo 2 integrates a responsive touchscreen complemented by four physical buttons, enhancing device control and versatility.

Boasting 32GB of internal storage for data and maps, the Karoo 2 excels in practicality, supplemented by bi-weekly software updates and bug fixes from Hammerhead. The included plastic out-front mount, utilizing Hammerhead’s proprietary clip-in system, provides secure attachment, though slightly less seamless than Wahoo’s design.

Charging via USB-C enhances convenience and efficiency, while the Karoo 2’s advanced processor and expansive touchscreen set it apart from competitors. Its functionalities, including the innovative “Climber” feature displaying real-time climb profiles, match those of rivals while introducing unique attributes.

The Karoo 2’s connectivity prowess encompasses Bluetooth, ANT+, WiFi, Smartphone, GPS, 3G, and 4G capabilities, allowing seamless communication with a variety of devices across platforms.

However, the Karoo 2’s Achilles’ heel is its battery life, hovering around 9 hours, lagging behind competitors like Wahoo’s Elemnt Bolt (15 hours) and Garmin’s Edge 830 (20 hours). This limitation might warrant consideration for longer rides or adventures.

Navigational accuracy and detail on the Karoo 2 are exemplary, making it a potent rival in the top-tier bike computer segment. Its sleek aesthetics, intuitive interface, and standout touchscreen position it as a compelling alternative for discerning cyclists seeking innovation.

While the Karoo 2 might not be the most budget-friendly option, it’s certainly not the priciest either, making it an appealing choice for those seeking a fresh and distinctive alternative in the market. Despite the battery trade-off, the Karoo 2 impresses with its array of features and robust performance, solidifying its place among the best cycling computers available today.

7. Garmin Edge 540 Solar

The Garmin Edge 540 Solar steps up as a worthy successor to the Edge 530, offering users two options: the base version or the solar variant. Both share identical features and physical dimensions, with the only distinction being the inclusion of solar panels in the latter.

In comparison to its touchscreen-equipped counterparts like the Edge 840 and Edge 1040 series, the Edge 540 operates solely through its seven buttons. Navigating menus and starting/stopping rides are efficiently handled by these buttons, albeit with a slight learning curve due to the absence of a touchscreen.

The Edge 540 impressively covers more than the average cyclist needs while maintaining a price tag that’s less than half of the Garmin 1040 Solar. The addition of new features like the ClimbPro mode, offering real-time climb information without pre-loaded courses, enhances its appeal.

However, the solar charging functionality, while intriguing, comes with some nuances. Leaving it in the sun won’t charge the device unless it’s powered on, and the solar contribution primarily slows down battery discharge rather than dramatically increasing the battery percentage. Users looking for a more extensive screen and touch interface might find the Edge 540 lacking in comparison to the Edge 840.

For those who prioritize functionality and cost-efficiency, the non-solar Garmin Edge 540 provides an abundance of features at a compelling price point. On the other hand, if touchscreen convenience is a priority, the Edge 840 may be worth the additional investment.

The Edge 540 Solar finds its sweet spot for users who value functionality but are willing to compromise on screen size and touch controls.

Summary: Making the Right Choice for You

Selecting the right cycling computer from the diverse range of options, requires a careful consideration of your specific needs.

For those seeking unparalleled sophistication and advanced features, the Garmin Edge 1040 Solar stands out with its impressive touchscreen and solar-charging capabilities, ideal for long rides and multi-day adventures. On the other hand, the Wahoo Elemnt Roam V2 offers a user-friendly experience, making it an excellent choice for hassle-free setup and navigation.

Riders who value compactness and affordability without compromising functionality might find the Bryton Rider 420 E appealing, while the Wahoo Elemnt Bolt V2 excels in simplicity and performance. If you’re after a robust GPS unit with a touch of smartphone-like experience, the Hammerhead Karoo 2 might be your match, though consider its battery life for longer rides.

For the performance-oriented enthusiast, the Garmin Edge 840 and Edge 540 both offer comprehensive metrics and navigation features. While the Edge 840 boasts a touchscreen and larger screen, the Edge 540 offers similar capabilities through physical buttons, making it a budget-friendly alternative. 

Ultimately, the right choice depends on your preferences, budget, and the specific features that align with your cycling style, ensuring a satisfying and efficient riding experience.

The Role of Cycling Computers in Training

Gone are the days when cycling computers were mere odometers. They have evolved into comprehensive training companions that provide real-time insights to cyclists, enabling them to monitor their performance while pedaling. 

This transition from rudimentary data displays to sophisticated training tools has elevated cycling computers to the forefront of cycling technology. Equipped with features like heart rate monitoring, power measurement, and GPS tracking, these devices have become essential for any cyclist serious about optimizing their performance.
