The unicycle succumbed to the heat wave. An innocent victim of climate change.

Space-Worthiness

For the unicycle to be used on Mars, the Li-Ion batteries require thermal protection and the electronics need to be encased for radiative cooling. The tire must be replaced for low temperature rubber and reduced atmospheric pressure.

With almost no atmosphere and a gravitational attraction of only 3.71m/s^2 the unicycle can carry about 300kg and travel up to 50km on Mars.
