Knog Blinder R70 Rear Lights Set

Overview of the Knog Blinder Road R70

The Knog Blinder Road R70 is perhaps one of the most reliable bike rear lights on the market today that I’ve had the opportunity to use.

It’s designed by Melbourne based, Knog who is well-known for designing high quality cycling accessories.

If you are looking for a rear light with a sleek design that will grab the attention of drivers behind you, look no further than this one.




At 70 lumens, the Knog Blinder Road R70 holds the credential of delivering an exceptionally bright and visible light.

The Collimated optics lens design allows the light to maintain constant brightness for you to be seen by other drivers from a distance.

And it comes with 5 different light modes that you can choose from.

I find myself using the Eco Flash mode 90% of the time for a simple reason.

With this mode, there are 3 flashes on the 3 smaller LEDs followed by a single large flash on the large LED at the bottom.

I find this type of flash beam attracts the most attention and it also last the longest. 20 hours!

Ease of Use

Knog Blinder Road R70 Back Side

As with most rear lights today, you can operate the Knog Blinder Road R70 with just a single button situated at the back of the unit.

Beside the button, you’ll find a battery level indicator light. There are only 2 levels of indication; low battery and fully charged. I find this itself is more than enough for my needs.

It also comes with an in-built memory where the light remembers the last light mode you were on. However, this gets cleared off each time you charge it.

Mounting Options

Knog have done good job by offering you 3 easy-to-attach rubber straps (long and short) that you can use on seatposts of various sizes from 22 to 32mm in diameter.

And yes, it’s also compatible with aero seatposts. You can easily swap the rubber straps without much hassle.

Having used and stretched the straps many times over my aero seatposts, I find that they’re prone to breaking.

The good news is, you can order them for FREE directly from their website.

Buy This If...

You’re after a bike tail light that does well in all departments; from brightness to battery life, built, mounting and most importantly design.

The down side?

It comes with a price tag that is higher than most of its competitors.

So, if you’ve the budget for it and want a rear light that blends in perfectly with your seatpost, then I strongly recommend the Knog Blinder Road R70.

Looking for Other Alternatives?

The Cateye Rapid X3 is an upgrade to the Knog Blinder Road R70 in terms of brightness.

There are 6 light modes available for you to play around. With 100 lumens at its maximum, you can be assured that it’s really really bright.

But with only 1 mode at 100 lumens and the remaining 5 ranging between 20 to 50 lumens, this is where the Knog Blinder Road R70 wins over. At 100 lumens, the battery only last an hour, which is a little disappointing really.

The light can be mounted on both round and aero seatposts as well as the seat stays. It comes with 2 rubber bands in the box, long and short for this.
