New horizons.

Garmin's latest entry in the GPS/GLONASS bike computer field is a minimalistic one. We're used to the Kansas-based manufacturer's GPS units overflowing with so many interactive features and modes that even we get overwhelmed. The Edge 25 Bundle Bike Computer takes the company's legacy in a different direction, one that favors minimalist functionality over flashy, overly complicated interfaces. The Edge 25 Bundle is a story of less — less price, less weight, less fuss — with one key addition: a Garmin cadence sensor. As precise as GPS has become, it still can't accurately measure pedal stroke RPM, a gap that the zip tie-free sensor fills while the Edge 25 directs you to new horizons of fitness.

The Edge 25 tracks cadence, speed, and trip information on a simple, monochromatic, 2.3cm² display, forgoing the colorful pomp of the brightly colored screens on Garmin's large models in favor of only the most important metrics and training data laid-out in the simplest, most accessible manner possible. It doesn't track the proximity of cupcake food trucks or plan petting zoo detours during training rides, but it does display a simple map with notifications directing the user through a preplanned workout or documenting the course of wandering base miles. It's focused on improvement and meeting personal training goals, not meeting baristas during a cycling tour of a city's coffee shops.

The Edge 25's GPS capabilities also let it count the laps of an interval circuit, alert the rider of distance or time goals during out-and-back workouts, and compete against a virtual opponent — all of which are designed to improve a cyclist's training instead of distracting them with superfluous data and features. Connecting the Edge 25 to a computer allows access to Garmin Connect, where you can upload, store, parse, and compare data across Garmin's online social training network.

The Edge 25 does feature ANT+ connectivity — something the less expensive Edge 20 lacks. The addition of ANT+ means that the 25 connects wirelessly to the included cadence sensor. It can also be linked to a heartrate monitor, expanding on the base unit's speed, distance, and mapping capabilities with some biometric numbers. The Edge 25 also features Bluetooth compatibility, so it can connect to a smartphone for many of the additional features found on the 500-series Edge models.

Using a smartphone as a launching pad, the Edge 25 can fire your info into the ether, linking with Garmin Connect mid-ride for features like live tracking and competition for K/QOM segments. Unlike models like the 520, though, the Edge 25 doesn't connect to Strava, which is admittedly the real unofficial battle ground for recreationalists and aspiring pros alike. Still, the blend of functional training options in a simple, lightweight GPS unit mean the Edge 25 is ideal for the cyclist who wants serious training data, not distractions.

Garmin 25

  • Familiarity: I've put it through the wringer

The Garmin 25 works exactly as advertised. Attaching the cadence sensor was a breeze and it synced up all on its own. German Connect has limited functionality, but I really only use it to keep track of my totals. If you’re looking for a simple unit with some of the advanced features found on more expansive models then the Garmin 25 is a good buy. I would buy this unit again.
