Oh see you've got your mini already! I was going to share pics but looks like you're all set. Will post for the sake of others searching for dimensions through the forum
Sorry the first one is blurry for vertical, was in a rush and camera was having a hard time focusing but that would be 2ft 4 in roughly when the rack is not fully extended like mine is currently.
These measurements were for when it is resting on the ground in folded position:
Height = about 2ft 4in
Length = about 3ft 4.5in
Width (pedals folded in) = about 2ft
