Daylight Visibility

We launched the world’s first intelligent, daylight visible lights back in 2013 and every light we’ve launched since has been designed with a focus on daylight visibility.

ACE is our fourth generation lighting product and combines five years of R&D with the experiences and ideas shared by our cycling community. It’s an innovative, no compromise, no nonsense approach that has produced an exceptional lighting product.

Its onboard sensors monitor what’s happening hundreds of times per second and this lets ACE’s AI learn your unique riding style and understand the environment you ride in. Featuring an all new processing engine with 46% more power, ACE quickly identifies and reacts to situations where you benefit from improved visibility.
