It looks like a neglected bike long since consigned to the shed, but this two-wheeled contraption is worth a small fortune. The ancient bicycle is a 1906 Indian Camelback, one of the first ever two-wheeled motorised machines and one which is hugely desirable to collectors.
Just 1,698 of the rare cycles were produced 105 years ago, with its 'unrestored' state meaning the relic could fetch as much as $75,000 at auction.
It was owned by the du Pont family, which bought the Indian Motorcycle Manufacturing Company that built it, and this cycle, which packs a puny 2.25 horse, has a single cylinder and top speed of 30mph, was last ridden in the Seventies.
One was featured in the 2005 film The World's Fastest Indian which starred Anthony Hopkins as New Zelander Burt Munro who spent years building a 1920 Indian motorcycle -- a bike which helped him set the land-speed world record at Utah's Bonneville Salt Flats in 1967.
The Indian cycles were the great rivals of Harley-Davidson, but the company eventually went bankrupt in 1953. The motorcycle is going under the hammer at Bonhams in Las Vegas, on January 12. Ben Walker from Bonhams said: 'This motorcycle is in such demand because of its condition and to restore it would actually take value off."
