A better way to produce aluminium Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
