San Francisco-based product and graphic design firm Shape Field Office is run by the husband-and-wife team of Karson and Mary Shadley. Shape Field contracted Nicholas Riddle, a colleague of Karson’s at California College of the Arts, to design and build the Shape Field Bike.

Riddle built this lightweight porteur-style bike with a Columbus SL frame and based the geometry on the 1978 Cinelli Supercorsa, which is Karson’s favorite. Being a porteur bicycle, it has a removable front rack with quarter details that can hold up to 80lbs. The bicycle features a laser-etched signage panel, a custom head badge, as well as Honjo fenders and Paul Component’s brake calipers around which the frame was designed.
