There are several questions that need to be addressed by designed Iohanna Pani before the "Cycle" bicycle-seat-into-backpack concept could be put into production. What materials would be comfortable but still allow for a light, crush-proof bag? Would the fixture for the seat post rub into the wearer's back? Is my ass really that big?
But size it down a little and make it capable of holding a phone and a few trinkets and there might just be a winner here. Nothing is more annoying than hauling around a useless bike seat with you all day.
