When you properly dock a bike, you'll see a green light on the dock.  If you did not see a green light, then that means your trip may still be open, and we will continue to charge you for your journey. 

If you’re having trouble docking a bike, first try a different dock. If you're still not able to dock your bike, please contact Citi Bike customer service or call 1-855-245-3311, now supported by Lyft. It's a good idea to enable push notifications on the Citi Bike mobile app, so you'll get a confirmation every time you've successfully docked your bike.

If you prefer to receive an email confirmation, you can sign up through your Citi Bike account online – log into your account through the website, scroll down to "Membership status," click on "Manage notifications," check the box next to "Yes, send me an email notification each time I return a bike" and click the "Change" button.
