Sungkuk Park of Busan, South Korea as created a concept bike that might actually work as a bicycle! His minivelo bicycle design uses conventional components, but he was inspired to design a frame reminiscent of human bones, which he believes results in a strong yet lightweight structure.

Bike designers have been removing material from frames by creating butted tubes for about a hundred years now because they realize extraneous material — like those bulbous, bony joints in Park’s frame — add unneeded weight, preferring to add weight for strength where it’s needed near the joins with other tubes.

Still, it’s a fun idea, and Yanko Design suggests this might be the right bicycle for Halloween night.
