Cowboy Cookie

Our first full-suspension platform, made right here in Saxony by Sour Bicycles.

Go big, ride home.

Got a big adventure in mind? Or maybe you’re keen to go hunt some PRs on your local trail? The Cowboy Cookie is down.

We built this bike in Saxony, by hand, to be a short-travel ripper, a quiver-killer, a bike for life. The steel frame stays true to Sour’s roots, and the aluminum rear end makes the Cowboy Cookie a speed demon ready to ride up, down, left, right… all of it.

This bike is for all-day rides, short rips, or heading out beyond the horizon. The steel frame, aluminum stays, and external cabling put durability forward, all while looking really, really good.

With 120-130mm travel up front and 120mm as standard rear travel, this bike follows the “less is more” ethos, producing a fast-on-its-feet platform ready to be an only child, or complementary to a wider stable of bikes.

All of this, handmade in Germany!

Efficient and Forgiving

The CC is the perfect bike for long rides, short rips, and everything in between. What started as a full-suspension sibling to our Pasta Party XC hardtail slowly morphed into its own category altogether. We wanted the geometry to be progressive, without sacrificing the all-day nature of a more conservative geometry like the Pasta Party. We love big days out, pedaling up, down, left, and right, and the CC is down for all of it.

We worked together with Actofive in Dresden to co-develop an efficient platform, a steel frame with aluminum stays, that’s efficient enough to set PRs, but capable enough to be a quiver-killer bike for big mountain trails as well.

Take all the gear, or leave it at home.

Sour Racing Development (SRD) is the birthplace of the Cowboy Cookie, and central to that is one of our Sour Athletes, Quinda Verheul. Quinda is an ultra-distance cyclist who has tackled some of the world’s hardest races, including the Atlas Mountain Race and Highland Trail 550, on her prototype Cowboy Cookie.

Using feedback from the field, we developed the Cowboy Cookie into the wide-reaching platform it is today.

Chris is the designer of the CC and the owner of Sour. Chris often has specific characteristics in mind when designing a bike, and this bike was no different. By having Chris on one prototype and Quinda on another, as well as a few friends in between, we were able to mesh the design feedback on the Cowboy Cookie and determine exactly how we wanted the bike to behave.

Horst-Link for all the efficiency, none of the chatter.

The Cowboy Cookie uses a Horst-link (four-bar) suspension design, known for its efficient pedaling and ability to handle technical, chattery trails. This design allowed us to fine-tune the anti-rise and anti-squat characteristics, creating a bike that just wants to ‘go’! Combined with the smoothing characteristics of steel and the stiffness of an aluminum rear end, this bike just gets up and goes when you push on the pedals.

Every aspect of the Cowboy Cookie has been built to enhance performance and rider experience. The geometry strikes a perfect balance between stability and agility, ensuring confidence on descents and nimbleness in tight corners. With robust components and thoughtful design, this bike is built to withstand the rigors of aggressive riding. Whether you’re climbing steep trails or descending rocky paths, the Cowboy Cookie delivers a ride that is both responsive and smooth.
