Mosaic Bikes

Born in the US cycling hotbed of Boulder, Colorado, Mosaic bikes represent the pinnacle of American handbuilt steel and titanium. The brand's range of custom, purpose-built racing machines are both incredibly finished and attainable, a testament to the sustainability of domestic frame building. Founded by former Dean head welder Aaron Barchek, Mosaic strives for excellence in everything it creates.


From the road-going RT-1 to the gravel-grinding GT-1, Mosaic bikes are quintessentially titanium, quintessentially American, and quintessential workhorses of the cycling world. Designed to conquer the rugged Colorado Front Range, their minimalist styling belies the racing soul that powers every Mosaic. Built with immaculate welds, both the RT-1 and GT-1 Mosaic bikes are custom-butted for the rider. And whether it's the local criterium, gravel romp, or Dirty Kanza, Mosaic's flagship titanium bikes are up to the task for a lifetime.

With Mosaic's staff testing its creations on the pavement, trails, and fire roads of the Rockies, Mosaic backs up its mindset with miles at every turn.
