Built for riders who value reliability, refinement, and timeless design, the Mariposa City is a modern urban bicycle crafted with the same care and precision that defines every Mariposa frame.

It is a handbuilt frame constructed from Columbus steel tubing, delivering the unmistakable ride quality steel is known for—supple, responsive, and exceptionally durable. Whether navigating city streets or heading out for a longer weekend ride, the Mariposa City offers comfort without compromise.

Paired with a Ritchey Adventure Carbon fork, the bike blends classic steel feel with modern performance. The fork features internal dynamo routing, creating a clean, fully integrated lighting system powered by the front hub—no charging, no hassle, always ready.
