'powerful lights, exact beam angles, long runtimes and multiple mounting options. Perfect for road riding.'

An Impressive Feature Set

Making this light combo one of the best choices for road cyclists.

Rock-Solid Mounting Options

Blinder 900 comes with two seperate mounts. A tough and flexible rubber handlebar mount that fits diameters from 22.2mm to 35mm, and a Go-Pro compatible mount that can position the light below your computer.

Industry Leading Battery Technology

Blinder 900 is powered by a 21700 3.7V lithium ion battery. This technology provides best-in-class power-to-weight ratio, meaning you get to enjoy a more compact design with longer runtimes than most other lights in this category.

Road Optimised Beam Optics

An innovative and considered design combines two wide beam optics with two narrow beam optics to provide high quality illumination for up to 100 m. At the optimum angle of 22 degrees, you get more light where you want it.

Intelligent Silicone Button

An LED light around Blinder's soft touch silicone button allows you to quickly see remaining charge and the charging status. A quick press of the button when it's off shows you remaining charge, with green being 100-50% charge remaining, yellow 50-25%, and red under 25%. When charging, a yellow flash indicates the light is being charged, which turns green when full.

Easy On / Easy Off

Blinder comes with a tool-less removable silicone strap for seat posts 22 – 32mm in diameter. Mounting is incredibly simple and using silicone straps means there’ll be no chance of damaging your bike.

Integrated USB Connector

No charging cable is required. Blinder's integrated USB-A connector plugs directly into USB ports, and charges in just 4 hours.

Product is great but could be better!

My honest review is that the light set works magnificently! I think the battery life is a bit low and would be great if that can be improved. I also think the rear light strap is harder than it needs to be. It’s bothersome to have to attach
piece to the strap. It would be great if it was just a one piece. I’d buy the product all over again but maybe consider one with extended battery life! Other than that, it’s great!!!

Blinder 900 & Blinder Square Rear Bike Light Set

Just recently bought Blinder 900 & Blinder Square Rear Bike Light Set. I had my doubts if the 900 version would suffice on my early morning or night rides. Well, I was wrong. The blinder is very bright even at the 2nd setting so I can conserve battery. The Square rear bike light is very helpful and awesome. It has good size and keeps me visible to traffic. I feel safer with these lights on my rides.

Good quality, poor value.

Overall good quality, but the 900 is heavy for what it is. I am surprised by the poor battery life on the Square Rear and how fiddly the seatpost attachment is. Also - USB A charging at this point is very behind the times. Again, good quality kit, but not good value, expensive and there are cheaper and better alternatives out there.

Party in the front, annoying in the back.

The front light is just fabulous.
The rear light needs an upgrade to be dimmable and also usb c as charging port.

two lights for my bike front and rear, but then off the bike: while walking through forest or on deserted roads those lights lighten my path and warn traffic from behind that I walk there - safety first

Lights are great for being seen after in the during and after twilights. Blinder 900 could have a bit more light bundling in the center that shows the trail further ahead.

Brilliant combo and great quality

These lights arrived sooner than expected, and work brilliantly! ( ba-da-bish! ). Elegantly low profile design, quality finishes, and charges quickly. Happy customer I am! :)

Bright & sturdy

Used on country roads & off road trails- particularly useful where visibility is important on low light conditions or where you find yourself in high speed limit traffic conditions.

Great quality and superb light beam

I 'bought these lights, after using, since years, the Knog Blinder Arc 640 (still working well). My son needed good lights for evening trainings and, after my good experience with the brand, I went directly to Knog, we are very happy with them.

Well made, high quality lights.

These are solidly built lights. The Blinder 900 is rock solid on a GoPro mount. It just goes and goes on the day strobe setting. The modes on the Blinder square are good fun. Even on the Eco mode, it's very bright. I usually use it on Speed-up flash mode, but mess around a bit, too. Highly recommended lights.

Knog fan for more than 6 years... and even more now.

I’ve always liked Knogg products, they are worth the investment. I’ve had the Blinder Road 400 and the blinder Rear 100, for more than 6 years and they still work as new. Now I wanted more power for trail/street riding and got the Blinder 900 and the Blinder Square 100 set. They are powerful, very well built and easy to handle.

After buying them I compared them to some Magic Shine lamps that are supposed to have better battery life, but for normal everyday use, I don’t really need more. I used to have one Magic Shine front light, 1000 lumens and it was alright but bulkier… I’m still a Knog fan.

I use it basically for long rides (the back light) always on, for 8 hours and it lasts all the way on eco mode, which is enough even for daylight. And the front light, maybe for 2 hours in the morning or 2 hours at night. I just love them.
