Open to people of all ages, the event is an initiative to promote the use of bicycles as a regular means of transport and thereby ensure a healthier and more sustainable mobility that helps to improve the quality of our environment and reclaim public space for the city’s residents. Another of its main goals is to provide the public with information on the rules and regulations for cycling in the city, to promote a safe range traffic where various forms of transport can coexist in harmony.
