The Batpod motorcycle from Christopher Nolan's "The Dark Knight" and "The Dark Knight Rises" is currently at auction through Propstore's Entertainment Memorabilia Live Auction in London, with bidding closing December 4 at 10:00 a.m. EST.

The bike appeared in key scenes across both films, including Batman's escape from the Joker in the first movie and as a getaway vehicle for Catwoman in the sequel. Designed by director Christopher Nolan and production designer Nathan Crowley, the Batpod was built by special-effects supervisor Chris Corbould as an alternative to Batman's Tumbler.

The motorcycle features a custom-fabricated chassis with a Honda 750 engine, 31-inch Hoosier racing tires, and a distinctive prone riding position that requires steering with the arms and shoulders. The cannon barrels are made of plastic, resin, and fiberglass. A light-up laser-targeting unit above the right hand grip is included but does not function.

The sale includes a custom metal display stand and a Warner Brothers certificate of authenticity. As of publication, bids stand around $300,000, though Propstore estimates the final sale price between $600,000 and $1.2 million.

The Batpod is being sold in non-functional, "rolling only" condition with no fluids, battery, fuel tank, or throttle controls. It bears battle scars from its use in filming.
