Apart from opening up either or both doors you can just slide those panels up on either or both sides to increase ventilation.
As well as that you can open the ends up so that air flows that way too,
In the previous version there was a mesh panel there that reduced air flow somewhat.
As it was the Moment worked very well for me and most people around my height (5'8") but for the taller ones, particularly when using thick mats, caused problems.
For folk above 6'2" or thereabout I would suggest the Scarp or the StratoSpire 1
