One of the more interesting finalists in the 12th International Bicycle Design Competition was this amphibious bicycle. The Amphibian Bike concept is the work of Chinese designers Bin Yu and Jian Wang, and in our book, is probably the design with the greatest potential for humanity among the strong field. The big difference with this bike compared to all the other amphibious bicycle designs we have seen is that it can be used as an ordinary bicycle on land. When used on water using the inflatable wheels which fit inside the existing wheels are inflated. The Shuttle Bike is still the best amphibious bike we have seen, though the weight overhead when on land is significant.
