Foldable, it fits well in any grade even tram and can be stowed in the top rack of the track in dry weather with no problems.
For me, the rear bolt went off 2 weeks ago at a standstill and I've only noticed when I was getting out of the train and wanted to continue. New Hinterradachs bolt came within 2 days of Hudora with me. For safety's sake I now all screws tightened again and slightly loose with screws glue, which I usually just take my motorcycle.
