CNC-machined frames
Hi, I am Simon.
Curiosity and the passion for technical challenges, together with my long-time experience in engineering, are my driving force behind innovative concepts. My high demand for relentless function and an aesthetic design, render my bikes with an exclusive character.
Since 2018, I design and manufacture ACTOFIVE bicycle frames, made in Germany.
