CIRCA's custom city bike packages are fantastic for your urban adventures. Your custom city bike starts with our durable, all-weather, hand-built frames and typically feature flat bars for a more upright position, wider tires to handle the abuses of city streets, and any drivetrain type you'd like, whether it's a belt-driven single-speed, fixie, internal hub, or a derailleur. Our proprietary construction system also lets you express yourself with a wide range of durable anodized color options or even laser graphics packages. Custom means custom: if you want it, we’ll make it happen. Heck, we can even put a bell on it.


Laser Graphics and Custom Storytelling. This custom city build for the Union Wine Company features a low-maintenance Gates Belt Drive, internal gearing and our client's company logo, laser-etched into the top tube. Have a story you’d like to tell? Want to add custom laser-etched graphics to get inspired, make your mark or celebrate your brand? Drop us a note if you want to discuss your own hand-built, laser-etched CIRCA with custom storytelling. You can also see additional samples of our custom graphics work in our Gallery.


Clean Town Runner Build. Weatherproof CIRCA Gray+Orange frame with super-clean, easy-maintenance Gates belt drive.


Screamin' Gold. This deluxe build uses color, texture and materials to create a super-outgoing city bike.


This XS City Build with Gates Carbon Drive is perfect for petite riders (5'0" to 5'4" height).


Our distinctive anodized finishes are more durable than paint, and can handle any type of climate.


Fixie in the City. This belt-drive fixie features our Icon PDX laser graphics package.


The Indigo city bike is the first of our Collaboration Series projects, styled by MOORE Custom Goods.


In a CIRCA design session, you can pick from a palette of durable anodized finishes and get creative with how colors are applied to different parts of the frame to create a bike that's distinctly yours.


Please refer to this guide for sizing assistance. If you're in-between sizes, don't fit the current size range, or require something different, please contact us about custom geometry options.

Custom City Bikes

Built for Men’s and Women’s Bodies. We use a sloped top-tube design on our frames, which reduces the standover height and tends to be more comfortable for many women. Although it’s not a full step-through, it’s a great compromise for rider comfort and structural strength.

Out of Town? If you can’t make it to Portland for a design session but would love to have your own CIRCA, just contact us using the “Get Started!” tool on the right edge of the page to get the conversation started.
