A French company based in Grenoble, called Engo, has launched a new pair of connected cycling glasses called the engo3 Cyclist. These glasses are designed for road and gravel cyclists who want real-time data displayed directly in their field of vision. To use them, cyclists need a compatible bike computer or smartwatch, such as Garmin models. The glasses display key metrics like speed, heart rate, and power, as well as alerts from a rear-facing radar that detects vehicles approaching from behind. The engo3 Cyclist glasses are slightly larger than previous models, with a frame that is 3 mm wider and 2 mm taller. They also include temple pieces that are designed to work with helmets. These features, along with a color display, double-tap function, and compatibility with Garmin Varia radar, are also available on the classic engo3 models. For cyclists climbing hills, the glasses show power zones as colored markers, helping them monitor their effort levels more effectively. The new glasses offer more than 20 hours of battery life, which is an improvement over the 12-hour battery life of the previous engo2 model. They connect to a range of Garmin devices, including bike computers like the Edge 530 and Edge Explore, and smartwatches such as the Fenix 7, Fenix 8, and Forerunner 965. However, to receive traffic alerts, users must have an external compatible radar, like the Garmin Varia, which is sold separately. Additionally, measuring power output requires a power sensor paired with the bike computer or watch. Priced at 350 euros, or 400 euros with photochromic lenses that adjust to light conditions, the engo3 Cyclist glasses aim to enhance the experience for cyclists who already have compatible equipment. They are particularly appealing to those who regularly monitor their performance data. However, for those without the necessary accessories, such as a rear radar light, the cost could be higher. In comparison, the Oakley Meta Vanguard, a similar product priced at 550 euros, focuses more on a built-in camera and voice-based information.
