Rear light for racing and time trial bikes as well as MTBs, which can also be easily mounted on aero posts.
Important in Germany: the light comes with a K number and is therefore StVZO approved!
I have been through all stages of development of this taillight and have been driving it for years. And often during the day too, so that you can see me better. Unlike bulky battery lights, this model is hardly noticeable on the bike and can be quickly attached and detached thanks to the special silicone strap. Tip for really bulky supports: you can extend both straps supplied into one.
The XK has two powerful bright LEDs to the rear and an additional two to the side. Good thing: thanks to the wide beam angle, you can also be recognized from the side.
Depending on the temperature, I experienced the lighting duration as four to five hours. Loading takes a maximum of two hours. The integrated battery is charged using the supplied micro-USB cable.
