Mosaic Bikes

World-class handcrafted titanium bikes

Est. 2009Boulder, ColoradoRoadGravelMountain

Boulder-based Mosaic has been hand-building titanium works of art since 2009. With a range that deftly turns from the road to the trail and even towards the steep drops of the singletrack, a Mosaic stands for impeccable craftsmanship, generous customization and supreme finishing. For those and many more reasons, Mosaic's small, passionate team has earned a deserved reputation as the leading light in American small-batch bike manufacturing.

About Mosaic

Titanium Title-Winners

There’s a fresh, unassuming quality to Boulder’s Mosaic Bikes and the people who work there that gives you the strong impression that they must welcome riders who knock on their door with a big pat on the back, a good coffee in a solid mug and a fireside chat about bikes, rides and what they can do for you. But don’t let the down-home vibes put you off: Mosaic makes high-performance, highly desirable handcrafted titanium bikes that hold their own against any workshop the world over. Unpretentious and absolutely serious about its craft, Mosaic mines a deep vein of European artisanal spirit-meets-time-honored American manufacturing, and the results are spectacular.

From the fast lines of the R-Series, Mosaic’s road/all-road line, to the US Gravel Nationals-winning credentials of the G-Series and its flagship GT-1, Mosaic’s bicycles cover the full width of the road and trail. Whether the rubber sticks slim or wide, when it’s a 1-Series, Mosaic includes a custom geometry at no extra cost and a custom frame fabrication tailored to your every measurement, weight, riding profile and goals. Then there’s the paint, which runs deep, with automotive-quality stock coloring frames in fades, geometric patterns, full-bleeds, fully custom detailing and more.

For a confessed “team of grubby makers making bikes that are handcrafted to be used and abused, not merely coveted,” taking this year’s top gravel racing prize with their sponsored rider, Brennan Wertz, was a validation of sorts, global recognition that metal bikes can win on the world’s fastest races and that a small-batch builder can shake the foundations of a bike industry that too often dismisses makers that aren’t selling shipping container-loads of frames. But that’s not the Mosaic way and never will be. They wouldn’t have enough mugs for a start.
