While competitors offer frames without displays, they engineered an augmented reality Micro-OLED display that projects real-time performance data directly into an athlete’s line of sight, all in a frame under 40 grams with 20 hours of battery life. For runners, triathletes and cyclists, that means glancing at pace, heart rate, and power output without ever breaking form or looking down. The display sits in peripheral view, feeding data mid-stride or mid-pedal so athletes stay locked into the road, trail or race ahead. Long-distance training and endurance events benefit most, where checking a wrist device can cost focus or rhythm over hours of effort; EngoEyewear.com.
