I've used Citibike from the beginning and I can no longer recommend the service or the app. I try to use Citibike to commute to work - the service is extremely unreliable - broken bikes, uncharged pedal-assist bikes, and broken docks plague the system so much so that over half of my rides have some sort of issue that makes me late for work. The app is also fraught with problems. I get error notices that my bike is not docked correctly when it is. Not worth the high prices for membership.
