In the past we brought you a bicycle that could accommodate laptop or briefcase, now we bring you a bike that IS a briefcase… at least partially. ThisÂ concept Bikoff design from Argentina-based Marcos Madia includes a briefcase as an integral part of the foldable bike’s structure, keeping the bike open during use and serving as reinforcement. Apparently the bike will include a “carbon-fiber body, disk-brakes with the cables running inside the tubes, rear suspension and a rather neat-looking seat/seatpost combo”. However, contrary to popular belief, the bike doesn’t store inside the case when not in use. Check out some additional images after the break.
