This is my first posting, bear with me...just wanted to add my 2 cents on the Giant Halfway (couldn't find the "hitchikers guide). I think it is a great bike, for one with small wheels. It folds & unfolds VERY quickly, which is one of the main reasons for my purchase, along with lighter weight of aluminum & dual foldiing pedals.
Folding: probably under 30 seconds. One screw-down clamp at the handlebars, one-click mechanism for the frame, raise the seat with quick-release clamp, and I especially liked that both pedals would fold up, push in & fold up. The front fork is cantilevered...fork only on one side, so it folds up pretty flat & isn't too heavy to pick up, but I wouldn't want to carry it very far.
Shifting & speed: Mine has 7 gear twist shift and is pretty comfortable to ride at a leisurely pace, if you want speed, I think you'll have to have bigger wheels. The rack and fenders look nice, but are quite rattly on my rough pavement neighborhood. The steering I'm finding is quite sensitive.
I bought this bike to use as short distance transportation when flying small airplanes (piper cub cruiser, cessna 172) It fits in the back seat of the cub perfectly, the carrying bag is useful, but not padded, which I think would be nice for the carryee when trying to carry it.
anyway I hope this helps anyone considering the purchase.
