Ultra is equipped with a click-dial fit system to ensure that it sits firmly, yet comfortably, on your head. Lumos Ultra is compatible with Strava and the Apple Watch. Our M-L helmet is adjustable from 54cm to 61cm and fits most adults & teens. If you measure above 61cm, or usually wear XL hats, then our XL size helmet is likely your best fit.
Lumos Ultra will simplify your life, protect your head and help prevent accidents. It comes integrated with 3 COB LED modules that give you a full 360˚ coverage - ensuring you’re seen by motorists from all angles. It also has turn signals that you can activate using the included remote or an Apple Watch.
