Key features

Gates Belt Drive

Clean and maintenance free, the Gates belt drive never needs oil and won’t rust like a traditional chain.

Durable Weatherproof finishes

Our sapphire-hard anodized finishes are lighter and tougher than paint and impervious to the harshest weather.

8-Speed Internal Hub

Got hills? The 8-speed rear hub should handle most of your rolling terrain.

Precision CNC Machining

Like details and accuracy? There’s lots to marvel at on our proprietary precision-cut lugs. 

Oregon built and sourced

We’re deeply committed to local production. Our frames are built by hand  in Portland, Oregon using locally sourced materials and processes.

what our customers are saying

I'd been riding ill-fitting, mass-produced bikes until my CIRCA. I knew a bike built for me would be an improvement, but I’ve been blown away at how much better it rides. The belt drive runs perfectly smooth. The design process was great and Rich was always quick to answer questions and help build the bike I needed. And it turns heads: I’ve been getting compliments since I first rode it away from CIRCA's shop.

Just go in and let them make you the best and most beautiful piece of bicycling art you’ve ever owned. I love my CIRCA!
