While still covering only the central part of Mexico City, ECOBICI is the fourth-largest public bike-sharing system in the world, after Hangzhou, London and Paris (Government of Mexico City, 2015).15 While installing bike stations, the Ministry of Environment of the Federal District has significantly expanded road infrastructure dedicated to bike use.16 It must be noted though that a large percentage of ECOBICI trips are made on roads that do not have bicycle infrastructure. In addition, better connections between bicycle lanes will be needed if this type of infrastructure is to develop into a useful network for bicycle users (Figure 3.2, right-hand panel). There are a growing number of bicycle parking facilities throughout the city, including in underground, Metrobus and trolley bus (zero-emission corridor) stations.
