Here's a pic of it folded to get an idea. The seat post will go down more and just FYI the front wheel is removed to fold.

NB; the disc is vulnerable to being bent, in transit, but, the use of a centerlock hub makes disc removal ,
and reinstallation when rebuild cones, a simpler task, and the disc can be packed separately to not be so exposed.
