Cycling in space

This image of ESA astronaut Alexander Gerst training onboard the International Space Station, was shared on Alexander's social media channels on 24 November 2018.

Alexander said "Almost like an evening mountain bike ride in the forest. Oh well. What we do to develop new textiles and instruments that will help keep both astronauts and earthlings healthy."
