What happens if you lose a BIXI?

Hello, I'm curious about what happens if I lose a BIXI bike while using the bike-sharing service. As someone who's new to this, I'm not entirely sure of the procedures and potential consequences. Could you please explain what steps I should take and what kind of fees or penalties I might face in such a situation? Understanding this will definitely help me use the service with more confidence. Thank you in advance for your help.
