Der Zeisel. It means 'the ground squirrel' in German, apparently, and it's the name given to this monster of a wheelchair which will tear through any terrain (short of lava).
Snow, sand, mud, stones – you name it, Der Zeisel can handle it, thanks two its twin tank treads and two 21 horsepower electric disc motors which churn out 31 pound-feet of torque, reaching speeds of 22mph.
Tearing through powder
You can kit it out with headlights too if you like, and it's even got a roll bar in case things get a little too hectic.
It's been used to plough fields and haul gear around in the snow, and its battery lasts around five hours per charge.
It'll set you back a pretty penny if you want one for yourself though - prices start at US$30,000, with upgrades like headlights costing extra.
