Bogotá has one of the world's most extensive bike-route networks, with more than 375km of separated, clearly marked bike paths called CicloRuta. Free Bogotá maps from PIT information centers show the CicloRuta paths.
In addition, about 121km of city roads are closed to traffic from 7am to 2pm on Sunday and holidays for the citywide Ciclovía, a well-run event to get Bogotá out on two wheels. You can rent a bike at Bogotá Bike Tours. Ciclovía runs along Carrera 7 all the way from La Candelaria to Usaquén – it's worth witnessing even on foot.
