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!
Auto motion sensing: the rear light gets brighter to signal to other cyclists or cars behind you.
Auto power saving: turns off after idling for 60 seconds, reactivates after riding again.
Low power warning : the tail light automatically switches to flash mode if the power falls below 20%.
Wide and bright lampshade angle for increased visibility to the rear, left & right sides.
Fits with both aero dynamic (e.g. Venge, Propel, S5) and round seat posts.
