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!!!

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

'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.
