NileGuide Expert tip:
Sunday mornings Reforma avenue is closed to traffic and the street is filled with families riding their bikes or walking. Because there are no cars to watch out for, this is a perfect day for this activity.
The Mexico City government now offers free use of bikes for public use in certain neighborhoods (Condesa, Cuauhtemoc, Roma). The system has been used successfully in other cities and it's fairly simple to use. In the designated neighborhoods, racks are located on the street and you pick one of the red and white bikes, ride around and return it to any of the other racks. There is a time limit and you must register to use it but if you don't mind following all the rules, it's a good way to see some of the most attractive Mexico City neighborhoods. As you can imagine, bikes should not be left unattended and you must be very careful when riding on the street.
