We make icons in an iconic bike city.

We don’t build them by the thousands in a factory on the other side of the world. We build them one at a time, by hand, in Portland, Oregon, just for you. Our quick-custom build process can get your bike done is as little as 4 weeks. 

Different with a Purpose

At CIRCA, we started with a simple question: How do we build great bikes using the resources of the local manufacturing ecosystem of Portland, Oregon? We broke some rules, created some new ones and ended up with a refined balance of form, function, process and of course, some really amazing bicycles.



Anodized Aluminum with Laser Graphic Options

We build our frames using durable, lightweight, high-performance aluminum alloys sourced from American mills, and coat them in beautiful, weatherproof, sapphire-tough anodizing. If you’re into graphics, we can get fancy and laser-etch all sorts of sassy graphics into the anodizing.

Hand-Built in Portland, Oregon.
