What's the best way to move around in München?

Hello fellow Müncheners, I just moved to Munich for a 6 month Internship and was wondering what the quickest and cheapest way is to get from one place to another. I thought of U-Bahn, my own bicycle, renting bicycles, E-Scooters maybe? I live pretty close to work and to the City Center so the distances i travel on a daily basis are not that far.

I am a Student so i do have access to Potential Student discounts. Would love to hear from your experience on mobility here in Munich 🙂
