Our opinion

The Knog Plus rear light will give you enough visibility when night falls to continue your training. Safety to cover your back!

Sylvain C.

Mechanical expert

This light is incredibly versatile. It can be attached to the seat post (22–32 mm diameter), a bag, a jersey pocket or a magnetic surface. It offers a maximum output of 20 lumens with 5 operating modes. It charges via a USB port and weighs just 12 grams. It takes only a few seconds to set up.

Battery life varies depending on the mode used, ranging from 2 to 40 hours. It is also splash-proof with an IP67 rating. It should be noted that this light is equipped with the latest generation of COB LEDs, which offer very high output with very low power consumption.

This bike light is ideal for me: It is very visible with fluctuating modes, sufficient autonomy, and great practicality for recharging! It can also be fixed on very aerodynamic tubes!! (Translated review)

This product is super practical to use, direct connection to USB port, varied and effective lighting mode. However, do not use it in the rain, it does not withstand (I have 'drowned' 2...) (Translated review)

The autonomy is more than correct compared to the size, several hours in flashing mode; at least two hours in fixed mode. The different modes are very useful. Very light, it weighs 17 g in total. I recharge easily via USB. We'll see how it holds up over time: I've just used it all winter to go to work and it has held up well. (Translated review)

Easy to hang, I appreciate the USB port recharge. For all orders, impeccable and fast deliveries, I prefer matériel-vélo for my purchases. (Translated review)

very powerful lighting that should allow to be seen even by the most inattentive drivers. Sufficient for a 3-hour ride. not tested beyond that. (Translated review)
