Since we don't get this bike in N.A. anymore I hadn't paid any attention, but it looks like Giant has developed an update on the Halfway concept. The new bike looks to have a different frame/latch, a stiffer handlepost and utilizes a Z-fold.
I've always thought the Halfway was one of those bikes whose detail execution didn't live up to the brilliance of the concept. Giant, as a bicycle company rather than a folding bicycle company, doesn't provide any folded pictures or dimensions, so I don't know if the Mk II answers the deficiencies of the original (large-ish folded size, non-standard components for little if any benefit).
