I hadn't heard of this until I saw an advert for one on Gumtree. It's a two wheeled all terrain vehicle designed for use on farms, estates etc and can be used for towing things (in the ad it's towing a glider) It comes with a 175cc petrol or 230cc diesel engine and has a high/low range gearbox with reverse. Made in Inverness in the Scottish Highlands the company seems to have gone bust in 2009. Yours for £825.
The bike is similar in concept to the Rokon from the USA
