Detailed Review

Well, it's that time of year. The temperatures start to cool off (finally) and the number of daylight hours slowly dwindles. Some of you have already crawled back into the cave and submitted to trainer rides, as most of us will eventually do, as our climates force us to (unless you are fortunate to travel and follow summer). However, there are still quite a few of us that have late season races, who are trying to squeeze in as many outdoor rides as possible. In order to do this, many of us are forced to start or finish (or both) in the dark. We all know riding a bike anywhere is risky enough all by itself, but when you are in the dark, it is imperative to be seen.

We have found that the Knog GEKKO is an excellent solution for the back of your bike. We are in no way suggesting this is the only light you use on your setup, but simply that it is a great choice for a seat post light.

Knog is a "hip" company that has been around for a while. They are well known for their lights whose cases double as a strap to secure it to your bike, helmet, bag, or whatever you choose.

The GEKKO features 3 super bright (45,000 millicandelas - that's a LOT) LED lights that you can get in red or white. Red is usually the standard for rear lights. You can choose from 7 colors so that it flows with your color scheme.

The GEKKO is powered by 2 AAA batteries which are included with your purchase. The estimated burn time is 30 hours constant and 220 hours using the flashing pattern. You can see the light below removed from the enclosure.

If you choose the Red LEDs, you will have a choice of 5 flashing patterns as well as 1 solid pattern. The White LEDs come with 2 flashing patterns and 1 solid pattern.

The feature that sets the Knog lights apart is the ease of mounting. The GEKKO follows that same pattern. However, we did run into a problem when attaching it to an aero seatpost. This was easily solved with a little bit of o-ring magic. Almost all cycling computer mounts come with a bag of o-rings to secure them to your bars. So, more than likely you have one laying around and if not, they should be easy to snag at any hardware store. You can see the GEKKO on the aero post below with the o-ring attached.

Price Range
Very cheap compared to some options out there.

TriBomb Bottom Line
We will be rolling with the GEKKO. A superior choice for a rear light on your bike.
