How to Build Your Own Race Lap Counter

3 August 2017 10:02:58 am AEST

Ever thought about building your own race lap counter? Well, now you can. Knog teamed up with the guys behind the legendary Mission Crit race in San Francisco to develop and build a Knog lap counter made entirely out of Blinder Mob bike lights for the race. You can check out Mission Crit's step by step guide to building a lap counter below. Enjoy.


Mission Crit was stoked to hear back from KNOG about teaming up for the spring 2017 edition of the race, and we were even more interested when KNOG presented the challenge of coming up with a cool way to showcase their bike lights. we’d been working out how to source a lap counter for the race, so the idea of making one out of KNOG bike lights was a pretty logical connection to make. with some help from the innovative team at AKQA San Francisco, we’re pretty happy with what we put together.



Step 1: investigation - breaking stuff is always the best way to start a project, right? We busted open a few of the lights to figure out how we could hack their on/off function. we soon realized that we didn’t actually need break the lights open; we could hack the lights just by stripping away the rubber casing on the on/off button with an x-acto knife and soldering wires to the button leads so that we could short the lights with the program we’d write.

Step 2: soldering & laser cutting - at the local tech shop, we cut the rubber casing away from the on/off buttons on each light, soldered wires on each side of the button leads, and etched the KNOG logo into an acrylic panel with a laser.

Step 3: programming - using Node.js, we wrote a program targeting the lights in such a way that they would form digit patterns and using a presentation clicker let us count down on button press from whatever number we set.

Step 4: frame construction - we opted to make the lap counter frame out of pvc piping so we could use the bike light’s straps to easily mount them. once assembled, we drilled holes in the back of the frame for the wires at the spots where the bike lights would sit, and then spray painted the whole frame black.

Step 5: hooking up - we connected the light wires to the relays, which were then connected to the raspberry pi that would parse the presentation clicker clicks to run the program we’d written to count the laps down.

Step 6: Assembly - this was super labor intensive; we determined what the light placement would be and trimmed wires accordingly, then threaded them through the corresponding holes and out the back of the frame. The KNOG logo was mounted in the frame using zip ties, and the relays were placed in a cardboard box in an attempt to contain the guts of the device a little.

Step 7: Action - the lap counter set up on the race course, blinding everyone from across the street. having digits burned into your retina is a small price to pay to be able to keep track of a kick ass race though, right?



Special thanks to Nate Waddington and Nick Mitrousis of AKQA San Francisco, and to RP Cuenco for their enthusiasm and technical expertise. We could totally R&D this baby and get it on the back of a pace bike in subsequent races. just sayin’.

what is a crit race?

14 July 2017 12:34:36 pm AEST

This year marks the 10th anniversary of the Red Hook Crit series, the world’s leading track bike criterium race. What started as one-off race organised by David Trimble to celebrate his 26th birthday has morphed into a global annual race series with crits in Brooklyn, London, Barcelona and Milan, bringing together the best riders in the world.

It’s a race series Knog are proud to have been a part of for many years, supporting great teams such as 2015 Champions Team Cinelli Chrome, Cykeln and F.A.S.T Amsterdam. This year we’re sponsoring new fixed gear crit team Revo Racing, who you can catch at the London Red Hook Crit on July 22nd.

 That’s all great and everything, but what the hell is a criterium?

A criterium is an action packed and somewhat frenetic bike race that is commonly raced on a closed road circuit loop for a duration close to an hour. Road bike or fixed gear, the pace is intense and is generally faster than that of your typical bike race.  It can also be a hell of a lot of fun.

Crit races are a great spectator sport. Unlike the tour or other road races where you might catch a glimpse of the riders once in the race as they ping past in a blur, crit racing tends to be held on smaller urban courses, where spectators can pick a spot and watch the action unfold lap by lap.

I want to race, not spectate.

One of the beauts of crit racing is that it is probably the most accessible form of bike racing to get into as an amateur racer. However, that doesn’t mean they’re easy. Criteriums are one of the hardest and most technically skillful forms of bike racing to compete in. Riders on average will be pushing 50km/h for the duration of the race, navigating tight corners, short straights all while trying to stay in contention at the finish.

WHAT ARE primes?

Primes are basically sprint sections of a race, signaled by the ringing of the lap bell, where racers have the opportunity to win additional money or prizes by crossing the line first at the end of that lap. These occur regularly throughout a race and are super entertaining for spectators.

The final countdown

Unlike road racing where you know when the finish will be, in crit racing, you often don’t find out until a few minutes before the end of the race. Race officials will be monitoring the lap times and will try to end the race as close to the set time as possible.  About 5 minutes or so before the end of the race the officials will ring the bell and display the lap counter to show how many laps there are to go. This is when the race intensity really kicks on a gear as riders jostle to position themselves for a sprint to the finish.

Check out some of the great highlights from this year's Cycle Messenger World Championships in Montreal.  Photos and words by Cedric Bonel.

"Here we are... The Cycle Messenger World Championships MMXVII is on (@CMWC2017)". 


Amazing day at the CMWC2017 for the qualifications with an alternate weather shared between sun/thunderstorm. The twelve check points was scattered all over the Olympique Stadium esplanade for a minus 30mns crazy ride. Let go for another alley cat now... #Poutine2017 #CMWC2017


Fresh after #KNOG party with a mini bikes foot-down session... in a pool.




Can you fell the presha.... Start line of the #CMWC2017 #Poutine2017

The main race was a blast... And very intense. The hot weather was there and transformed the esplanade into BBQ. Nothing better to have the feeling be in hell ✨🤘✨ #CMWC2017 #Poutine2017


JF the Canadian rep was there to introduce the new KNOG products to the crowd. Stay tune for a big announcement really soon about the #KnogPWR#CMWC2017 #Poutine2017

Knog Oi x Kosuke Masuda

1 June 2017 2:51:00 pm AEST

We've been a longtime admirer of Kosuke Masuda  (or, ko)- a Japanese artist and Buddhist priest from Yokohama, Japan. His work has featured regularly on such sites as the Radavist and recently he did a mindblowing collaboration with MASH

We decided to get in touch with ko to see if he would be interested in creating a series of unique Oi engravings for the Knog display at Eurobike and Interbike shows. Ko agreed, and what he then sent back was incredible...

Below are a few photographs of Kosuke Masuda's incredible work & some words from the great man himself.  Enjoy.

I remember when I got the Oi in my hands. I thought these bells were so beautiful and I was excited to start working on them. The smooth black surface and the beautiful shape, I was wondering what kind of tone they have.

The process of my work is called meditation and samādhi (state of being totally aware from present moment).  It's not just sitting or yoga in general trend. It could be any time and any style. Have you ever imagined how this meditation is going to be? Or “ Let’s do the same meditation I did before”?  It’s like when you ride the same road with your bicycle every day, you see a different view and have different feelings each time. You can’t do the same meditation or ride you have done before. My art is not about the result. I am more approaching process side as meditation.

So what is it about? It’s like an ongoing drawing of a line. A line consists of dots. The line as the harmony and the dots as the phenomenon. You might see mountains, trees, waves, stars and space in my works but it’s consisted of dots. These are the harmony of the phenomenon. A dot could be a star or just dot, it depends on how you looking at or how you imagine it over the dots and lines. The truth is not in the artworks or even in nature. The truth is in your soul or heart, in Japanese we call it “Kokoro”. So my process of work is that a dot brings another dots and a line brings another line. Then the concentration of dots and lines expand the truth of our Kokoro. There is no beginning and ending. It’s all about phenomenon and harmony.
