Winter bike / Snow bike thread

The wheels on the Fatback look like they'd crumple if you hit them with a snowball.

The whole bike was a special build. Looks like a customa UMA-90 rim, twice the cut out size, and 28 spokes per wheel.
If all you do is ride soft snow. The tyres will protect the rim.

But at ~7 PSI. It would'nt take much to bash the rim, on harder terrain.
