A Russian company has come out with a fold-up motorcycle that can go just about anywhere. It's two-wheel drive, meaning that both the front and back wheels are powered. It's low-cost, too: according to the manufacturer's Web site, it comes in at well under $2,000. It's only available in Russia at present, but they plan to make it available in the USA too. If they can do so at that sort of price, I predict they'll sell a shipload of them.
Here's the original, development model - read more about it here.
And here's the current, upgraded version (described here), with uprated tires and frame.
If they bring that here at a halfway decent price, I'll be a customer for sure. It can fold up into the trunk of a car, making it a great recreation vehicle - not to mention emergency transport under difficult circumstances.
