Blinder 900 Front Bike Light

Great visibility with this light. I ride dark roads with little to no lighting before sunrise, and this light allowed me to see any holes, bumps, turns, crossing animals with enough time to slow down or avoid. Would highly recommend!

Bright light

Doubles as a awareness to others flashing light to a bright light in darkness. Long battery life is suitable for longer rides.

Really Happy

The order was simple and easy to make. The item was shipped in good time, with tracking. Well packaged, presented well. I have used the light a couple of times and it does charge quickly. I find the quality of lit up area to good. I would recommend if you’re considering a front headlight.

'a powerful, road specific front light that mounts exactly where you want it.'

‘Our top choice for front lights, the fantastic Knog Blinder 900 (Best Bike Lights of 2025)’

An Impressive Feature Set

Which makes Blinder 900 the best front bike light in its class.

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.
