Hello Alert,
the mentioned movement of the cranks is a normal feature of the freewheel,
there’s no way to “switch off” this characteristic.
You should only push, but not pull “her” 
But you might try the following:
Fold your LT not fully (B),
I mean hold the bottom tube in the position like shown below - A - (more here How much play in Strida 5 belt? ):
Now try again to rotate the cranks, depending on your seat height (and therefore the height of the carrier’s edge), it might work…
If the cranks are free you can order this part,
it is usually supplied on all EVOs and should be available at your local dealer.
