ENGO has added a cycling model to its engo3 head-up display glasses, and its distinguishing feature is not the display. It is that the glasses read a Garmin Varia rear radar and draw approaching vehicles in the rider's line of sight. The glasses cost $399.95, and the radar is a separate purchase.
In short:
- What it is: engo3 Cyclist, a 41 gram pair of sports glasses with a monocular display, $399.95 with tinted lenses and $449.95 with photochromic ones, checked September 15, 2026.
- The new part: rear radar alerts drawn in the field of view, which requires a Garmin Varia radar that ENGO does not sell.
- What it is not: an assistant. There is no camera, no microphone and no chatbot. It shows numbers.
What ENGO added
The engo3 Cyclist is the wide-mask version of a display ENGO already sold. The company describes the frame as built for road and gravel riding positions, and lists it at 41 grams with a 140 mm by 60 mm frame, against 39 grams and 137 mm by 58 mm for the standard engo3. Both list more than 40 real-time metrics and the standard model is given a 24 hour battery.
The feature ENGO leads on is radar. The glasses connect to a Garmin Varia rear radar and, in ENGO's description, "display approaching vehicles directly in your line of sight, no need to check a mirror or glance back". ENGO calls the result a radar data screen where "each icon represents an approaching vehicle, moving up the screen as it nears you, positioned relative to your location".
ENGO publishes two limits on that in its own copy, and both are worth reading before buying. The Varia radar is required and is sold by Garmin, not by ENGO, so the $399.95 is not the cost of the feature. And ENGO states that the setup "can improve situational awareness" but "is not a replacement for cyclist attentiveness and good judgment", warning that failing to stay aware "could result in serious injury or death". A vendor publishing that alongside its own marketing is unusual enough to quote.
Compatibility is where the fine print sits. ENGO says engo3 works with more than 81 Garmin devices and with Apple Watch, but that radar alerts are "not available for Apple Watch compatibility". It lists the Garmin Edge 530 and Edge 830 as partially compatible, limited in how many sensors can connect at once.
Why this sits in a different category from AI glasses
ENGO is not building the product that dominates smart glasses coverage. The company describes its own technology as "light augmented reality (Lite AR)" and says it created ActiveLook, the platform its glasses run on, to keep augmented reality "compact and truly useful, providing the information you need without cluttering your vision".
That is a narrower claim than the one made by camera-and-assistant eyewear, and it puts engo3 in the display glasses bracket rather than the AI glasses bracket, a split covered in our guide to AI and smart glasses and in the display glasses comparison. The buying question is not which assistant is better. It is whether a rider already owns the Garmin hardware that makes the headline feature work.
