Folding size would justify the price. The 200€ one won't help you if you need to fly it. Even for road trips, for 2 adults in a city car, the size constraints could be enough to not bring two biggish 200€ along. Basically, the choice comes to a 200€ bike you never bring along, or 800/1600€ bikes you can bring anywhere.
