What is the extra time fee for Citi Bike?
Excuse me, I'm curious about the Citi Bike rental service and I'm wondering about the specifics of their fees. Could you please clarify for me what the extra time fee is? Is it charged after a certain period of time has elapsed, and if so, how much is it per hour or per day? I'd like to ensure I have a clear understanding of the costs before using the service. Thank you in advance for your assistance.
