O (FLASH)

Outstanding design and Outstanding performance! That is what the O rearlight stands for. Suitable for mounting on the seat-post or seat-stay tube of each type of bicycle.

Highlights

The O rearlight is very easy to mount and easy to use. It has a big, integrated push button in the middle, which can be used perfectly even when wearing gloves. Next to its unique and original design, the O ensures a high degree of visibility and therefore safety on the road.

Functions & Performance

But what does this “high degree” of visibility mean? In the case of the O, it means a visibility distance of 400m in which you are seen by other road users. But it also means a high light output of 15 Lumens. Do you want more information about Lumens? Take a look at Our Expertise page, where we explain the subject of light and its measurements in more detail.

Mounting the O rearlight to the tubes of your seat-post or seat-stay is really simple. You just take the rubber bracket, which is supplied within the package, and strap it around the tube. The length is adjustable, so that it can be fixed to tubes with a diameter ranging from 15-35mm.

The O has an impressive burntime of 50 hours and works with 2x AAA batteries (also supplied within the package). Are you running out of battery power? You don’t need to worry about riding in the dark, because the battery load indicator will give a clear signal on forehand. When the indicator starts to burn, it is time to change your batteries. To do this, you simply take a coin and open the O rearlight. For more information, please check out the O rearlight instruction manual on this page.

* The O rearlight comes in a steady and flash version. The flash version is not conform to German regulations.
