The Aero-X is a bicycle tail light designed to ensure you’re seen both day and night. Equipped with motion-sensing technology which kicks in by doubling the brightness when you're slowing down or riding in rough terrain. A clever power saving feature extends the run time, turning itself off after idling for 60 seconds, with auto-reactivation when your start riding again.

Featuring our most versatile function, the Aero-X easily mounts on round and aero seat posts. A great improvement for your road safety!
