Can I put my bike in the Metro?

Excuse me, I was wondering if I could clarify something about the transportation rules for the Metro. Specifically, I'm curious if it's permissible to bring my bicycle onto the train. I understand that space can be limited and safety is a priority, so I just wanted to double-check if there are any regulations or guidelines in place regarding bicycles on the Metro. Thank you for your time and assistance in clarifying this matter.
