If you've already signed up to become a Bike Angel, you'll first need to turn on the Bike Angels station points in the Citi Bike app or on the Citi BIke website by following these directions:
The directions are the same for both Android and iOS: download the newest version of the Citi Bike App, log into your account, go to Map Settings, and turn on Bike Angels.
You can also view the Bike Angels station scores in your browser at the Citi Bike website. Log into your account online, then click the layers icon and activate the Bike Angels station scores.
Now that you can see which stations are offering points for taking a bike away (black oval with an upward arrow) and which stations are offering points for returning a bike (white oval with a downward arrow), you can earn points depending on the pair of stations involved in your Citi Bike trips. See our Bike Angels microsite for ways to earn points.
