Engo 2 is an augmented reality head-mounted display released in 2022. It is a pair of sports sunglasses made by Engo Eyewear with a small built-in head-up display that shows workout data, such as pace, heart rate, power and cadence, from a paired sports watch, cycling computer or smartphone. The glasses use ActiveLook, a microdisplay platform from the French company Microoled, and are aimed at runners, cyclists, triathletes and other endurance athletes.

The Engo 2 is Engo's second model of head-up display glasses. Unlike general-purpose smart glasses, it has no camera and no GPS of its own; it only shows data sent to it over Bluetooth. As of September 2026 Engo's US store still lists the Engo 2 and its variants alongside the newer engo3 model, but shows every Engo 2 version as sold out.

Announcement and release

Engo Eyewear announced the Engo 2 on 3 August 2022 in a press release datelined Boston. The company opened pre-orders at US$329 and said orders were expected to ship in September 2022. It described the Engo 2 as "the lightest HUD on the market", citing a weight of 36 grams for the standard size, and gave a battery life of 10-12 consecutive hours. The release said that the glasses used ActiveLook 2.0 technology and that the ActiveLook microdisplay had received an Innovation Award at the Consumer Electronics Show in January 2021. ActiveLook announced the ActiveLook 2.0 software on 30 August 2022, with a reworked user interface, a revised software development kit and improved Bluetooth Low Energy connections.

On 15 September 2022 Microoled released an ActiveLook app for Apple's watchOS, which let an Apple Watch send real-time data such as running pace, heart rate, running power, stride length, ground contact time and vertical oscillation to the glasses. The announcement named the Engo 2 as the latest ActiveLook-compatible model. A second press release on 5 December 2022 said the Engo 2 was available from Engo's website for US$329.

In the United States TechRadar listed the price as US$329.95 in May 2023, and in mainland Europe as 329 euros. Engo later added lens variants. The Engo 2 Photochromic was announced on 31 July 2024 at US$349.95; its lenses change from a clear tint in low light to a darker tint in bright sun.

Design and hardware

From the front, the Engo 2 looks like a pair of wrap-around sports sunglasses with a single frameless polycarbonate lens. It comes in two sizes. Road.cc lists the Standard size at 138 mm wide and 49 mm high and the Large size at 139 mm wide and 61 mm high, with a temple length of 133 mm; the lens is a category 3 polycarbonate lens with vents. Engo's press release also lists moisture and dust resistance, impact protection and 100% ultraviolet protection. Engo sells the frames in black, white and stealth colors.

The electronics sit around the bridge of the nose. Cyclingnews described the layout as a battery pack on the left, an on/off button above a magnetic charging port in the center, and the display module on the right. The display fires its image upward toward an angled mirror, which projects it onto the inside of the lens. TechRadar described the same assembly as a micro-OLED projector, a mirror system and batteries tucked in around the nose bridge.

Display

The display is a monochrome Micro-OLED microdisplay. ActiveLook's developer documentation describes the microdisplay in ActiveLook glasses as a low-power Microoled panel with a resolution of 304 x 256 pixels and 16 grey levels. When ActiveLook introduced its NexT module in November 2021, it described the display as a monochrome AMOLED of 304 x 256 pixels that uses less than 1 milliwatt.

The image is seen by the right eye only, so the Engo 2 is a monocular display. Road.cc reported that the display is directed onto the right-hand side of the lens but appears slightly left of center and toward the upper part of the view. Engo says the data appears 5 to 10 meters ahead of the wearer, a focal distance it says also suits farsighted athletes. For other vision correction, Engo says contact lenses are required. An ambient light sensor adjusts the display brightness automatically. Road.cc described the display color as yellow-orange.

Controls, battery and weight

A gesture sensor between the eyes lets the wearer switch data screens by passing a hand in front of the lens. When the gesture sensor is turned off, the wearer swipes across the lens above the nose bridge instead. The glasses connect over Bluetooth 4.2.

Engo quotes 10-12 hours of battery life. TechRadar and road.cc both reported a charge time of about three hours, using a magnetic charger. TechRadar gave the weight as 36 or 41 grams depending on lens size. Cyclingnews weighed its Large pair at 40.3 grams.

Software and features

The Engo 2 is set up with the ActiveLook smartphone app, which can also record an activity on its own. In the app the user can change the screen brightness and the position of the image and turn the gesture sensor on or off. Engo's product page lists compatibility with Apple Watch (Series 4 or later, watchOS 10.1 or later), more than 70 Garmin models, Suunto 5 and newer Suunto watches, iOS 13.0 or later and Android 6.0 or later, with more than 40 selectable metrics. ActiveLook's consumer page lists the platforms and apps that work with ActiveLook glasses, including Strava, Garmin, Apple Watch, Suunto and Navigr8.

On Garmin devices the glasses work through an ActiveLook data field installed from the Connect IQ store. In 2024 Cyclingnews described a configuration in which each data screen is written as a set of numbered codes in brackets, with up to four screens per activity type. Cyclingnews also reported that the Engo 2 did not work with Wahoo or Hammerhead cycling computers. Turn-by-turn directions through the Navigr8 app were only available on Apple devices when Cyclingnews tested the glasses, and TechRadar reported in 2023 that navigation was only possible with Suunto.

Company background

Engo Eyewear was founded in Grenoble, France. ActiveLook is a division of Microoled, a French maker of micro-OLED displays. TechRadar's review, drawing on an interview with Mark Prince, Engo's general manager and chief commercial officer, described Engo as a wholly owned consumer subsidiary of Microoled and ActiveLook as a third, separate company from the same group, with its own API, SDK and customers. Eric Marcellin-Dibon, Engo's chief executive, said at launch that ActiveLook 2.0 "gives users greater ability to customize the data projected into their field of view."

Engo began shipping the engo3 in April 2026. Auganix reported that it has a color-coded display, weighs 38.5 grams and has more than 20 hours of battery life, at 349.95 euros with tinted lenses.

Reception

TechRadar's Jeremy Kaplan gave the Engo 2 an overall score of 3 out of 5. He found the display "perfectly visible even in bright sunlight" and the Apple Watch setup easy, but called the ActiveLook software "maddeningly confusing and unintuitive, especially so for Garmin owners". He also criticized the lack of a user manual and found the gesture controls "a bit temperamental".

Road.cc's Stu Kerton gave it 7 out of 10. He praised the light weight, clear optics and comfort and reported no connection drops with his Garmin devices, but found the display harder to read when riding into direct sunlight. Cyclingnews' Will Jones rated it 50 percent. He said the glasses did what they promised, but he found the Garmin setup the worst part, the weight balance on the nose uncomfortable, and the block of electronics in the center of the lens a noticeable intrusion into the field of view. He thought the glasses could be useful in specific cases such as time trials.

Gear Patrol's Ben Emminger called the Engo 2 one of his favorite running accessories to launch in 2022, noting that the brightness adjusts automatically, but wrote that the arms lack an aggressive bend, which limited how secure the glasses were while running.
