The way I get to university

Everymorning I walk from my home to the subway's station called "Lo Vial". It takes me around 5 minutes to get there. After that, I travel on the subway until the station "Puente Cal y Canto" around 15 minutes and I take the bus that takes me to the university. It takes me around 10 minutes.
It takes me around 35 minutes get to university, wich is very fast because I have classmate that it takes more than 1 hour!
The problem is that the subway is full of people in the morning. So sometimes I have to wait another train, and when I get take it, I go the all trip very cramped, wich is so annoying. And that's the reason that everybody on the train are stressed, and you can see people fighting everyday!
That's why I'd love get to university on bicycle. I'd travel alone, it would be healthy and very fun. The problem is that I dont have a bicycle, and maybe it would be dangerous.
