Hi, you can put bikes in the boot/trunk of the larger inter city buses.
You can but... You may have to remove wheels, pedals and turn the handle bars to store them. You cannot take them into the bus.
"Can I board the bus with a bicycle?
Bicycles are not allowed on board unless the bus has an underfloor luggage compartment (never inside the bus itself) where they can be placed folded/covered to avoid damage to themselves to other packages. Preference is given to suitcases other packages."
