I just watched this video by Drew Feustel showing him having trouble walking upright after 197 days on ISS:


They say once you have learned how to ride a bicycle you can never unlearn this skill (crossed hands excused)

It made me wonder: would people returning from space have to learn how to ride a bicycle the same way they have to learn how to walk again? What about hoverboards or Segways?


The overwhelming majority of physical issues stemming from prolonged spaceflight are due to loss of muscle and bone mass. Astronauts typically make a full recovery shortly (few months) after their return to Earth's gravity well. Provided they have the physical strength to push the pedals and keep the bike upright, a returning astronaut shouldn't have any trouble riding a bike.
