Gutten tag,

I'm gonna stay in Zurich for a year, begining from September. I'm wondering to know how these transportation systems work for me: bus, rent a bike and tram.
1. I had a look at the ZVV website on tickets, but there are some questions: it seems monthly is appropriate for me(at least for the frist month!) but I'm not sure if there is a limitation on how many times you use it. Please possibly let me know which kind of ticket is good for me.

2. I have no idea about the renting bike system?! is it free? where can we ride? everywhere? how long is the rent?

1. A monthly pass has unlimited usage but a multi-ride day ticket has to be stamped before each travel session. If it's a daily ticket and not just an "hour" ticket, you can still ride around the city for unlimited trips on that particular day.

2. There is a system called Zuri Rollt which is a free bike rental service. I think you have to leave a deposit and maybe your ID but it might not be the optimal solution for a daily commute.
