Over the past decade, bicycle self-repair workshops have been growing throughout France. These collectives, which are still a recent phenomenon, have so far been hardly studied, despite being places of socialization to mobility, in a context where people are pressured to change behaviors (especially in terms of mobility) to cope with environmental issues. Beyond enabling people to be more independent by teaching them how to repair their own bicycle, do these workshops bring about a more global change in their participants’ lifestyles and views of society? Are they an opportunity to transition to more sustainable lifestyles?
