I'm more lost now then when I started researching this.....

Here's my question --- these are just examples.

#1
* I want to start my bike ride at the Zoo (Zurich Zoo)
* I live in Zurich
* I will take the tram to the zoo and do my ride, and ride home.
-- How do I purchase a bike ticket
-- What type of bike ticket do I purchase

#2
* I want to start my bike ride in Zug
* I live in Zurich
* I will take the train to Zug and ride my bike back home (in Zurich)
-- How do I purchase a bike ticket
-- What type of bike ticket do I purchase

A- where do I purchase the bike ticket
B- What bike ticket do I purchase
C- I have a Half price card, AND, I use the SBB mobile app on my phone
-- I only see an option to purchase a full day bike ticket
D- HOW do I purchase a 2nd, 2nd class train ticket on my phone - if that's what I do.
