What is winter expedition cycling on Siberian ice roads and frozen rivers like? โ€” answered 12 November 2026

The Berlin geographer. He takes winter expedition cycling to another level entirely: fatbiking across frozen rivers like the Lena and the Kolyma zimniks, dragging a pulka sled behind his bike at -40ยฐC to -50ยฐC.

His trip reports are gold because he doesn't just do the standard highway: he actually rides the seasonal ice roads (avtozimnik) that only exist for a few months when the permafrost and river ice freeze solid enough to carry heavy trucks. Absolutely insane logistics, but methodically planned down to the last dry-lubed bearing.
