Several blogs have published shots of Argentina-based Marcos Madia's Bikoff concept, a shortlisted finalist in the Seoul Cycle Design competition as shown on Design Boom. However, there seems to be some confusion, as some other blogs are mistakenly claiming the bicycle is intended to fold into the briefcase itself. That's neither accurate nor is it the point of the bike. As Madia explains [italics ours],
'Bikoff' is a small foldeable bike which features a briefcase incorporated into the frame. there is an intimate relationship between the briefcase and the frame. the briefcase completes the frame, giving it great structure.
...This project was aimed at those who do not use bicycles, those who drive their cars every morning to the office. 'Bikoff' was born to convince these people to leave their cars and to ride every morning to their offices.
