Gaëtan always cycled to get around, in his youth in the countryside, until his exclusive means of transport to go to work. Passionate about science from a young age, he was a microelectronics engineer for many years. He discovered more advanced bicycle mechanics during his cycling trips around the world, and created with courier friends in 2013, a free self-repair bicycle workshop in Neuchâtel called “the Black Office”.
