Built up around our open rear triangle frame geometry – just like our Erik Urban, fitted with Gevenalle cyclocross gear and hydraulic double action brakes, Mattis offers a solid ride for the urban adventurer gone afield.

The frame
Rock solid & lightweight
Made from our own StoneWeave material, Mattis’ frame is as stiff and durable as can be. The innovative mix of lightweight carbon and tough basalt gives you a reliable ride all day
StoneWeave
Enjoy a responsive and comfortable ride, thanks to Mattis’ StoneWeave frame. The benefits of StoneWeave are numerous. Based on carbon, Mattis is light and stiff, while the volcanic basalt laminate absorbs shocks from the road. Best of all, StoneWeave is recyclable.
Low-maintenance
Due to the asymmetrical geometry of Mattis’ frame, you save time on maintenance. No spot is unreachable, making your day as simple and clean as your bike.
Gevenalle friction shifters
Made for
durability
Mattis features shifters from renowned American brand Gevenalle that were originally developed for the hardship of CycloCross enduring mud and hard crashes.
Instant tactile feedback
These friction shifters are trusted for their reliability, robustness and ease of use. They differ from standard shifters in that they offer a more traditional and intuitive feel. Gevenalle’s levers provide instant tactile feedback with a satisfying click, making them a perfect match for Mattis. Whether you’re racing competitively or just taking a leisurely ride, Gevenalle’s friction shifters are designed to help you get the most out of your ride.
Durability
Designed for cyclocross, these incredible shifters endure even the toughest terrains. They are more than capable for the urban environment and occasional trip out in nature.
Dual-Action Hybrid Disc Brakes
Powerful, precise
& reliable
Suited for gravel road adventures through the woods Mattis is kitted with Juin Tech’s R1 dual action hydraulic disc brakes, which are super responsive and lets you brake in an instant when needed.
Precision
Stop instantly. Enjoy a reliable braking system that obeys your command. This is especially important, on fast-paced rides, whether you need to avoid an impact, slow down in a quick turn or just want to stop and enjoy a beautiful scenery.
Weather resistant
Disc brakes handle wet and dirty weather way better than traditional rim brakes. This is because the braking system is located in the center of the wheel rather at the edge right next to the tyre.

A sustainable eco system
Coh&Co is on a mission to raise the bar on how we experience riding, maintaining, and owning our bicycles. We have developed an ecosystem to keep bikes rolling and by your side for many years to come.
It starts at the design process where we push the limits of longevity with our sustainable material technology StoneWeave – and we close the circle with a transferable lifetime buy-back guarantee. We refurbish or recycle every registered bicycle returned to us when it has reached the final crossroads in its lifecycle.
650B wheels
Speed,
acceleration
& control
650b wheels on commuter bikes are an ideal choice for cyclists seeking an improved ride experience. These wheels offer increased speed, stability, and control, as well as an improved weight, aerodynamics, and overall durability.
Acceleration
Despite the illusion, smaller wheels are in some ways faster than larger ones and a lot easier to accelerate. 650B wheels make Mattis a snappy and easy to handle ride while emphasizing his sporty feel.

Frame sizes
The size 54 is usually suitable for heights between 160-175 cm, and size 57 is good for heights between 175-195 cm.
However, it depends on whether you have long legs and a short torso or vice versa. We measure the size based on the length of the top tube, so the reach is important when deciding on a size.
We recommend trying the bike at a dealer before purchasing, or feel free to ask us for help.
