Initially, we had limited knowledge about how to address the challenges of our bicycle manufacturing processes. But our lack of preconceived notions turned out to be our greatest advantage. We are consulting with various experts, we repeatedly encountered responses like, "This is how it's always been done" or "That's the established method." Fueled by our passion and spirit, we chose to trust our own intuition and break the tradition. In our workshop, we embarked on a journey of experimentation and innovation.

Our belief extends to various initiatives aimed at strengthening the very foundation of sustainability. From collaborating with leading institutions and suppliers to create shared standards for a sustainable supply chain, adopting biodegradable and eco-friendly resources, and nurturing our local communities. Our journey toward a greener horizon is propelled by our collective determination to make a positive impact on the planet we all call home.
