Plenty of people have tried to reinvent the bicycle, but I've always thought that what we currently have—two wheels, a standard frame, and some handlebars—is pretty much perfect. And then I saw the horsecycle.
An entry in the Seoul Cycle Design Competition 2010, "Horsey," is a simple kit that allows anyone to turn their roll into a gallop. The designer, Eungi Kim, explains:
horsey' is an attachable bicycle ornament/accessory which makes one's bicycle look horsey! the 'horsey' package includes wooden ornaments (horsey shape body), metal parts, and screws. the manual is very simple so that anyone can easily arrange it according to one's needs. through this 'horsey' project. I wanted to give a special look to bicycles so that people would care about cycling not only as transportation but also as a lovely pet.
I just hope my horse doesn't get bored being a single-speed. [designboom]
