An auction due to take place on Saturday in North Palm Beach, Florida will feature the last motorcycle owned by Evel Knievel before his death in 2007, as well as a range of other motorcycles including a replica 'Batcycle' from the 1960s 'Batman' tv series.
The Knievel bike, a 2005 Harley-Davidson Screaming Eagle Custom V-Rod, is custom embroidered and painted with the daredevil's initials, as well as keeping his personalised Montana numberplate, 'EVEL2.' The estimate price is $40-60,000 (approx. £25-37,000).
Also featured is a 'Batcycle' used to film the 1967 'Batman' movie. The bike, based on a 750cc Yamaha, is being sold as a joint lot with the now-famous Batmobile, also used for movie and television filming in the cult classic show starring Adam West. The estimate price is $125-175,000 (£80-110,000).
A number of classic American motorcycles are also for sale, such as a 1947 Harley-Davison WL and a 1946 Indian Chief and sidecar.
The auction, ran by RM Auctions, is a liquidation of the Cars of Dream Museum in North Palm Beach, a collection of American automotive history amassed by owner John Staluppi over the past forty years.
The auction also has a collection of Americana valued at upwards of $1million, as well as a vertible history of American muscle cars, featuring everything from 1930s custom hod rods up to a 2011 NASCAR race car and Ford Mustang.
