I spoke to Lars Strömgren, Stockholm’s Vice Mayor for Transport and Urban Environment, about the city’s journey from car-centricity to a cycling-friendly capital.

We talked about his childhood on the back of his grandmother’s bike, the cultural shifts that made cycling mainstream and the urban planning philosophy that underpins Stockholm’s transformation - including how storytelling, kid-focused design and even building with wood all fit into a sustainable transport vision.

13 years ago, Simon Munk decided to take local councillors on a bike ride to show just how dangerous roads were for cyclists.

Without knowing it, he'd started a revolution. He tells his fascinating story as this week’s guest.
