Award Winning Design! Rear Light for both Aero and Round Seat Posts


The GUEE AERO-Xe is winner of the 2016 TAIPEI CYCLE d&i Awards!
The GUEE AERO-Xe is a cleverly designed bicycle LED rear light that can be fitted on both aero and round tubing (seat posts) due to its adjustable wing design. This means you can swap this tail light between bikes with no hassle in a matter of seconds! It illuminates with a wide beam  and increases visibility from the rear as well as the sides - which makes it the perfect choice for commuters! The built-in rechargeable battery can be charged via a Micro-USB port.
