A friend of mine forwarded me this link to the ebay auction. Something seems very off about all of this.
The studio that is selling these replicas got a pretty angry note from WB a while back about producing and selling an unlicensed batpod from The Dark Knight.
In this auction, they're asking for the $35k up front, with no images of their product except for studio released stills. Forget process pics, a shot of a frame or maybe the body mold - they aren't even showing a blueprint or anything they've personally built except for the batpod.
Also, they're saying it will come with your choice of electric or gasoline power, which makes me double suspicious considering the extensive frame modifications that would be needed in order to completely change the powerplant of a motorcycle like that.
I'm not saying this is a scam, but there's an awful lot of weird loose ends if you start researching these things extensively.
