Shaft drive - constant-velocity joints on either end of the shaft so that the steering can turn, and the shaft is splined telescopic (like a car's propshaft) to allow steering/suspension movement. It also reduces unsprung weight (which is good for suspension) because the cranks/riders legs are independent of the steering/suspension. Also it'd be pretty uncomfortable to ride if your legs bumped up and down with the suspension!
From that picture though it looks as though if you turn the wheel to the right it bangs into the shaft.
and the shaft has a kink in it, so surely can't rotate?
