2.- Every Sunday I ride a bike.
Perfect activity to share with the family and if you don't have a bike, the Mexican government will rent you a bike on Avenida Reforma by presenting an ID.Highly recommended to get to know the city and one of the main iconic avenues of Mexico City known as Av. Reforma that runs places like Basilica de Guadalupe passing through the Historic Center and towards the Lomas de Chapultepec (near Polanco).
A good option for a relaxed and fun Sunday.
