Hello Pavol
You can always check directly on the SBB- timetable, in which trains you are allowed to bring your bike with. For that you just have to specify the option “carriage of byciles required” under “advanced search”.
By travelling with a InterCity you may also need a previous reservation for your bike. For more Information, please take a look on this link: Carriage of bikes on the train | SBB
Kind regards, EllenvS
