People seem to be fascinated by multimodal vehicles. Amphibious cars and planes, flying cars, flying submarines, and submarine aircraft carriers are all dreams of a retro future. Add the amphibious bicycle to the list. The fact is, it’s just a whole lot simpler for cars to be cars, boats to be boats, and planes to be planes. Sure, an amphibious bike sounds cool on paper, but are you going to be using it mostly for biking, or boating? If you’re boating that much, why not just use a boat? Find a circumstance where having an amphibious bike is more useful.
