There IS a modern-day amphibious bike!
We have never been so fricking excited to be wrong. Guys. GUYS. There is a modern-day amphibious bike! It is named the C.H.U.N.K. 666 Aquacycle — which is a great name! Tell it to do the Truffle Shuffle! — and it floats.
Here’s the unofficial-official account of a test run a few years back by a guy with the improbable name of Megulon-5:
Megulon began pedalling, and the bike … sorta bobbed around and floated upriver as the wind pushed it. Later analysis would deduce that the fan was too deep in the water (about two-thirds submerged when it should have been half). Still, it was pretty cool to see a bike float around.
C.H.U.N.K. 666 has been described as as “a mutant bicycle club and civic society which has been building, riding, destroying and rebuilding human-powered choppers, tallbikes and battle wagons for 20 years” and “a postapocalyptic chopper bicycle club in Portland, Oregon.” They’ve improved on the initial Aquacycle design, too. For more on their work and the compromises you need to make to cycle on land and on water, check out this video:
