Looking for info on getting from Budapest to Belgrade with bike this August. I have emailed the Hungarian railway network and was told that bikes are not allowed. This phase of my journey will take place after riding from Berlin to Budapest before continuing from Belgrade to Istanbul. I have heard that you can get your bike onto a bus but will need to take it apart and put it in a box first. If this is true, it will be a big hassle taking place right in the middle of my trip.
Any info appreciated.
