inspired by the dutch bicycle culture. the bag goes from bike to shoulder bag by simply lifting it off the bike. instead of lugging your things on your back the bike does the work for you. if you run out of space the inner liner can be pulled out, doubling it's capacity. there is also a removable inner bag of adjustable size. it can be attached to the top of the bag while it is on the bike tripling the volume. As a shoulder bag there are no signs of its relationship to the bicycle, no hard plastic hooks or connectors.
