Gravel Bikes

A sedimentary rock made of sharp fragments embedded in fine-grained material.

Some gravel rides are exclusively along dirt roads. Others throw in a bit extra, like mud, snow, water, paved roads, singletrack, and killer climbs.

Lightweight but durable, our Breccia gravel bike can get through anything riders and ride organizers can throw at it. And if the terrain gets tough, it’s easy to pick up and carry across, because as our friend likes to say “in every biker is a built-in hiker.”

The frame can accommodate all the gear you want/need including fenders, fat tires, frame bags (for snacks, don’t forget to bring plenty of snacks) and hydration.

And, like all Ruckus frames, we stuck with a design that is easily built and serviced – no proprietary parts to keep you off the roads, trails or whatever.

Where does inspiration come from? For us, selecting the colors for our bicycles starts in nature with the minerals below our wheels.

Clinochlore purple

While many think of “clinochlore” for its distinct green color (No? Is that just us?), the mineral consisting of magnesium aluminum silicate can also be found in deep shades of purple and yellow.


Blue kyanite

Like the blue sky on a beautiful day, this frame calls you to skip your chores and head out for a ride. The name, and color, are inspired by the aluminosilicate mineral found in aluminum-rich metamorphic pegmatites and sedimentary rock.
