Engo is not inventing a new display: it is making the glasses it already sells lighter. The brand sums up the difference with the standard engo3 in one sentence: “Same display, same software, same compatibility”. What changes is the frame, and with it the weight and the battery life.
Engo3 Titanium: a frame printed layer by layer
The frame is a one-piece design in 3D-printed aerospace-grade titanium. Engo stresses this manufacturing method: the frame “is not cast, moulded or assembled”; it is built layer by layer. On its product page, the brand presents the engo3 Titanium as “The lightest AR sport glasses”, at 28.9 g on the scales.
Against the standard engo3, the official product page quantifies the gap using 28 g this time, not 28.9 g: 28 g versus 38.5 g, and more than 24 hours of battery life versus 20 hours, with a titanium frame replacing the polymer one. A full charge takes less than two hours.
Engo also highlights what it has left out: “No camera. No microphone. No speakers. By design.” The glasses pair with a Garmin or Apple watch and simply display training data in the wearer’s field of vision.
What the cyclist sees in the glasses
The head-up display is in colour, with heart rate, pace and power zones that shift from red to green. The official product page lists more than 40 selectable data fields, up to six per screen.
On the bike side, Engo announces compatibility with more than 81 Garmin devices, Garmin Edge computers and the Apple Watch. The Edge 530 and Edge 830 are listed as “Partially compatible”. The glasses can also display alerts from the Garmin Varia rear radar, a feature that the official product page says “is not available for Apple Watch compatibility”.
A version with photochromic lenses also appears on the page, to go from low light to full sun with a single pair.
500 units, no reissue
The engo3 Titanium is an “Edition of 500”, in a “Numbered production run”, and Engo states: “No reissue”. As of 10 October, the brand’s French online shop lists it at €569.95.
