Knog Blinder R70 Rear Lights Set

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 creating 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.

  • 4 Powerful LEDs with a maximum brightness of 70 lumens that makes you highly visible on all occasions.
  • 100% Waterproof USB-male Plug for charging. There are no rubber seals to cover the charging ports.
  • Compatible with all types of seatposts. You can use it on round (22-32mm) and aero seatposts.
  • Single button operation used toggle between modes and to turn on/off.


  • Sleek design. Not the typical rear light design you’ll commonly see.
  • Free replacement straps. You can order them directly from Knog’s website.


  • The rubber strap is prone to breaking. This is mostly reported on aero seatposts.


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 lasts 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 has done a 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.
