The Raphson RF01
Steel, drawn outside the lines.
A handcrafted frame built around sharp square profiles, visible structure, and the freedom to finish it your way.
Signature form
Square by design.
The RF01 turns the familiar steel bicycle silhouette into something more architectural. Its square-section tubes create a stance that is direct, rigid, and unmistakably Raphson.
Made, not moulded
Honest material. Visible craft.
Each RF01 is aligned and welded as a steel structure. The joints, edges, and construction stay legible—the process is part of the finished frame.
S235JR steel
Your finish
Bare or bold.
Choose the direct, industrial character of uncoated steel or protect the frame with a professional powdercoat in a color that makes it yours.
Built to be ridden
A frame with presence.
Square steel profiles bring confidence and stiffness to a platform ready for a personal component build.
