It is pretty easy to
It is pretty easy to disassemble the Vendetta to ship it in a smaller box.
Wheels off, seat off, boom and chainstay off and probably separated, handlebars off, might leave the fork on but it is easy to remove too and at this point everything is pretty flat. You don't need a real big box, especially if you are not shipping wheels. I'd be inclined to ship the wheels separately myself.
You could potentially leave the front triangle together and just unbolt the handlebars and carefully rotate them to be parallel to the slider and boom - minding the cables. with no pedals this but would then be relatively flat.
