I've always been amazed by, but the Wallpaper limited-edition bikes really take the cake.
The "International" bike, designed by Kinfolk and Coat, is a racing model that can be broken down and stored in a leather bag created by Nivaldo de Lima. The "City" two-wheeler by Level goes for the Japanese-salaryman look and fits into a Brooks briefcase.
Though these amazing bicycles were originally intended as works of art, you can actually buy them via e-mail. The "International" version starts at 2,450 pounds ($3,815.65), while the "City" model goes for 1,255 pounds ($1,954.55).
