Knog Plus Rear in the test: We took a very detailed look at the lightweight LED rear light from the Australian manufacturer Knog and show you our test impressions here.
The StVZO-compliant rear light from Knog focuses particularly on lightness and simplicity and scores well with it. The elongated shape creates a clearly visible cone of light. So if you are looking for a light, simple and inexpensive rear light, you seem to have come to the right place. We'll now show you how the Knog Plus Rear taillight performed in our test.

Our test impression Knog Plus Rear
packaging and assembly
Just like the taillight itself, the packaging is also very light and small and is made entirely of recycled cardboard - full marks for that! Installation is very easy and intuitive with the rubber ring. In addition to mounting on the seat post, the Knog Plus Rear taillight can also be clipped onto clothing, helmet or backpack. The rear light is held firmly to the seat post by a rubber ring, but a more precise adjustment is not possible as there are no gradations, as with other lamps in our test. There is also no rubber pad for better mounting on the seat post. We think it's very clever that the lamp can be magnetically detached from the holder, so it doesn't have to be reassembled after charging.
Operation and battery life
The StVZO-compliant version of the Knog Plus Rear has two modes: High (20 lumens) and Low (11 lumens). The operation is very easy with the only on/off button, although the smooth-running push button is a bit small. In high mode the battery life is two hours and in low mode up to 3:30 hours. This is quite sufficient for daily commuting, but may not be enough for longer tours. A special feature occurs when charging the battery: The Knog Plus Rear fits directly into a USB port and can be charged this way. An additional cable is not necessary, making it perfect for quick charging at home or in the office.
At 21,25 grams including the holder, the Knog Plus Rear is the lightest rear light in our test series. The side visibility is fine at 180 degrees. The price is absolutely justified at 19,99 euros and makes the rear light even more attractive. Thanks to the various mounting options and the simple, direct charging option, we think the rear light is perfect for commuting and short bike tours.
What is allowed, what matters?: Battery taillights
Battery-powered rear lights: When it comes to lighting, cyclists today benefit from uncomplicated rules and high-quality technology. However, it can't hurt to know what the StVZO requires - here's a brief overview. Cyclists in particular have benefited from the new version of the legal regulations on bicycle lighting in June 2017: the requirement to carry battery-powered lights has been lifted; Today, bicycles only have to be used “during […]
