“In pursuit cycling, every watt counts. The difference between a PR and a missed opportunity can come down to maintaining the perfect aero position and never breaking form. I'd lose precious watts every time I had to glance down at my bike computer to check my speed or heart rate. Those little disruptions add up.
As the current U23 Irish National Record holder in the Individual Pursuit, my training is meticulously structured around specific power targets and aerodynamic optimization. I face a constant compromise: either maintain perfect position and guess at my metrics, or sacrifice a few watts by breaking position to check my bike computer.
engo3 Cyclist changed the game for me. Now I get all my key metrics—average speed, heart rate, duration—right in my line of sight while staying in the pursuit position. I can focus on my effort, stay fully aerodynamic, and squeeze every ounce of efficiency out of my ride. It's been a nice boost to my training, and I'm confident it'll help me break the national record for the Individual Pursuit this year.
The psychological benefit has been equally valuable. The pursuit is as much a mental challenge as a physical one—the ability to push through intense discomfort while maintaining perfect technique requires absolute focus. By eliminating the distraction of checking metrics, I remain completely present in the effort, resulting in more consistent power application throughout the entire event.
As I target breaking the national record for the Individual Pursuit this year, engo3 Cyclist has become an essential component of my preparation. The technology doesn't just provide data—it integrates that data into my performance without compromising aerodynamics or focus.
For any track cyclist serious about performance optimization, engo3 Cyclist offers a competitive advantage that's difficult to overstate.

Everything runners ask, answered.
Will I even notice a difference?

How is engo3 different from Meta Oakley Vanguard?
engo3 is a pure performance display built for serious runners and cyclists: a lightweight AR heads-up display (38.5g) that projects your stats (pace, heart rate, cadence, and more) right in your line of sight, with 20+ hours of battery life and no camera, music, or notifications to distract you.
The Oakley Meta Vanguard is a general-purpose smart glasses product with a built-in camera and Meta AI, giving you sport stats through voice commands or audio rather than a visual display, with about 9 hours of battery life. In short: engo3 keeps your eyes on the road and your data always visible, Vanguard is a multitasking device where sport is one feature among many.
How long does the engo3 battery last?
24+hours
Can I use engo3 for trail running or ultras?
Yes!
Does engo3 have a camera?
No, engo3 doesn't have a camera. It's built purely as a data display: no camera, no music, no notifications, just your real-time stats (pace, heart rate, cadence, etc.) projected in your field of view. That's a deliberate choice to keep it light (38.5g) and focused on performance rather than content capture.
What is the weight of engo3?
38.5 gr
