The engo3 smart glasses are aiming to solve a familiar problem for runners, cyclists, and other serious athletes: constantly checking a phone, smartwatch, or bike computer to stay on top of performance stats. With a built-in display positioned in your field of view, the engo3 lets you see key training data at a glance while keeping your focus on the road, trail, or track.
Available now for pre-order directly from the manufacturer, the engo3 comes in two versions. The standard model costs €350, while the photochromic model is €400. That extra €50 gets you lenses that automatically darken depending on ambient light, which can be especially handy during early-morning runs, changing weather, or training sessions that start in bright daylight and finish closer to dusk. Shipping is scheduled to begin on March 31.
What makes these sports smart glasses stand out is the amount of information they can display without cluttering your vision. The manufacturer says users can choose from more than 40 data fields, with up to six data fields shown on a single screen. That means you can tailor the display to what matters most—like heart rate, current pace, speed, and other metrics—without breaking stride. For athletes following structured training plans, this kind of heads-up style view could be particularly useful during interval workouts, tempo runs, or hard efforts where stopping to look down at a device can be disruptive.
The engo3 uses a color-coded display designed for quick readability. Despite integrating electronics and a display system, the glasses are stated to weigh just 38.5 grams, keeping them light enough for longer sessions. Battery life is also a major selling point, with the manufacturer claiming more than 20 hours on a charge—an important detail for endurance athletes, cyclists on long rides, or anyone who doesn’t want another device that needs daily charging.
Control is handled through gesture support, reducing the need to reach for a phone mid-activity. In terms of compatibility, the engo3 is built with athletes in mind: it supports connections with more than 81 Garmin devices, including wearables and cycling computers. Apple Watch users should also be able to use the engo3, widening its appeal for people already invested in Apple’s fitness ecosystem.
For anyone searching for smart glasses for running, cycling, or training, the engo3 positions itself as a performance-focused option rather than a general-purpose gadget. The pitch is straightforward: keep your eyes forward, see your metrics instantly, and train with fewer distractions.
