Car rentals are available in Medellin and can be found around El Poblado as well as at the airport.  Car rentals start at about 100,000 Colombian Pesos a day and increase depending upon your various upgrades. Make sure to understand exactly what you’re paying for as a handful of reviews of various car rental companies are particularly scathing. Always take photos and videos of the car prior to leaving the car rental agency. 

The government has an ever expanding bicycle renting program called Encicla. Currently they have 50 stations around key parts of the city that allow access to 1,500 bicycles, however the plan is to increase this to 370 stations. You can find a map of the stations here. Unfortunately there are not many stations in Poblado at this time. The closest is perhaps Cuidad del Rio alongside the Modern Arte Museum. The area is pretty flat around there so is great for cycling.

As a tourist you can apply for the Encicla scheme, which requires completing an online form and submitting photos and copies of your passport scanned at 150% normal size. We believe that you need to activate your Civica card (the same card that you use for the Metro) at their main office in Belen.  If you're in Medellin for a period of time this could be a great option, however perhaps not ideal for those in town for only a few days.

However, there are two other options you may choose from to get your biking fix as well. The first is the Ciclovia. On sundays, the local government shuts down major streets (such as avenida Poblado) to allow pedestrians the option to run, skate, or bike. You can rent bicycles near the Santa Fe Plaza on Avenida Poblado. (Read more information on the section entitled “Ciclovia”).

Lastly, there are biking tours of Medellin that have received high praise (see the Outdoor Activities section).
