Knog Plus: the small and mighty bike light

20-10-2025

Translation: Elicia Payne

It was love at third sight. After a few teething problems, the Velolicht Plus from Knog has become one of my new favourite accessories.

As the story goes, paper clips inspired the development of my new favourite bike accessory. No idea whether this is true or not. All I do know is that when I look at the shape and function of Knog’s rear light Plus, the story makes perfect sense.

Like the humble paper clip, which quietly and conscientiously keeps your paper safe, the mini light keeps you safe on two wheels – or when trail running, hiking or walking the dog. And in the same way you feel lost when you don’t have that inconspicuous bent metal wire to attach several pages together, I soon missed the Knog Plus when it suddenly refused to work.

Sometimes big feelings come with time

Let’s go back to when it all began. It was basically love at first sight when I took what they claim to be the most versatile bike light in Australia out of the packaging. That was the beginning of September. The thing worked perfectly to begin with, and then stopped. I still have no idea why. The test device was most likely faulty, and with that my feelings changed on second thought. More on that here:

Knog has since replaced my test device and I’ve given the Plus a second chance, as promised. The luminosity of the lightweight (17 grammes) is 20 lumens, the battery life at full power is around two hours, with a maximum of 40 hours. From my experience, the first is accurate, but I wouldn’t know about the latter.

On our shop, you’ll come across both units of measurement. Both describe the brightness of a light source. Lumen measures the total luminous flux emitted by a light source. It describes the brightness of the light source itself, regardless of how the light’s distributed. A bike light with a high lumen rating produces a lot of light, which is particularly useful for being able to see well in dark surroundings. For example, 400 lumens is enough to effectively illuminate dark streets or forest paths. Lux*, on the other hand, measures the illuminance, i.e. how much light reaches a certain area. The lux number is crucial to know how well the area in front of the bike is lit. A lamp with 50 lux can illuminate the path in front of a bike evenly and brightly enough. The perfect bike light should therefore have both a high lumen and an appropriate lux.

The Plus comes with a total of five modes and chip-on-board technology. Its COB LEDs are designed to provide maximum brightness for up to 90 per cent of the battery life. The battery’s charged via a USB-A connection, and the light should be visible up to a distance of 450 metres. The Plus connects to its holder via a small magnet. By the way, you can get the Plus as a separate front light or as a set.

The Plus is inserted into its small holder in the same way as a paper clip works.

Love at third sight

So me and the little red thing are reunited. It was love at third sight. So far, everything has been working smoothly and the Plus has been promoted from the seat stay to my helmet. The combination of the tiny rear light and a radar function on the seat post should make me even more visible in the autumn fog and at dusk.

It was a happily ever after, after all. Knog’s bike light won me over in the end.
