Cycling in Mexico City is dangerous. But over the last two decades it has become less so. New cycleways, a large public bicycle-sharing scheme, various government cycling promotion projects and an abundance of official signalling demanding respect for cyclists have made bicycles visible as worthy vehicles on city streets. For cycloactivists, however, such improvements are not enough. Cyclists are frequently harassed, attacked or run over by motorists. Cycloactivists thus demand more and better cycleways as well as increased measures to address injustices in mobility issues across the city. They do so through protests, information campaigns, public performances and academic debates, and crucially, by cycling through city streets. This means that they use their bodies as symbols, to highlight their vulnerability. Along the way, they often break existing traffic rules to highlight how unfair they are and to draw attention to other demands. I refer to their efforts as experiential cycloactivism, which highlights cyclists making themselves vulnerable as a means of denouncing illegitimate rules and policies that need to be changed. I conclude the analysis by suggesting that their style of rule-breaking is a type of ritual with which they seek to improve the city, not burn it down.
