Using bamboo as a sustainable alternative to carbon or metal makes a bit of sense because all you have to worry about are terminates and fire. When you dip into cardboard and begin to check the radar for storms before pedaling to the grocery store, then you’re wasting everyone’s time. They estimate that it’ll cost about $30 to build the cardboard bike, so one day we might be rolling around on disposables you can buy in five packs.
