This complete Doppo Ronin bike offering is 1 of 1, as it was created as a feature bike to highlight our 'Ride Me to the Moon' Collection developed with GHOOOST of Japan for the 2025 MADE Bicycle Show in Portland, OR.

A tremendous effort went in to executing this amazing custom paint job, which is carried over to the Sim Loader bag offering as well. There's endless unique details to be found.

We've built this Ronin with a perfect mix of high end products from White Industries, Paul Components, Shimano, and a full range of some of SimWorks most trusted and versatile parts to piece together an endlessly capable all-rounder. Full specifications are indicated in the table below.

Doppo Ronin

Doppo Ronin is a bicycle frame that most completely embodies the spirit of the Doppo series of frame models from SimWorks. It was renamed to Ronin following a model update from the previous ATB and has continually evolved with each update to remain a practical tool, with subtle new feature in refinement. These new features include our original rear dropouts and a reshaping of the seat stays.

The name Ronin (浪人) signifies "wandering the world without being bound by anything." This ethos is reflected in its design, emphasizing versatility within the many standards and conventions of an ever evolving bicycle landscape. It accommodates a wide range of preferred configurations and tire sizes, offering greater flexibility. The bike that you select for 90% of the riding you do—this is the essence of Ronin as a tool.

If you’re searching for a great bike for everyday use, extended day rides on mixed surfaces, or multi-day tours, choose the Ronin. It's versatility and practicality will help reduce some of the stresses of your journey. Ronin is a bike that can easily adapt to your lifestyle, serving as a capable tool and reliable companion.

As a true mixed-terrain, modern adventure bike, Ronin can take you confidently to the destinations you’ve been charting in your mind. It’s a worthy selection to become a trusted companion for memorable adventures, and seeking contentment through a dynamic life lived via your cycling experiences
