Personally I see all my travels as an opportunity to source bike gear usually unavailable to me.
This being the case I'd buy a bike bag and a big suitcase.
Put a toothbrush in the bike bag, a pair of clean undies in the suitcase, and bring the cases back full of goodies ;)
Seriously though, if your bringing a bike, I vote MTN bike.
