This batcycle is known as Batblade and was ridden by Batgirl played by Alicia Silverstone and by Robin played by Chris O'Donnell in the 1997 movie "Batman and Robin" which also starred George Clooney, Arnold Schwarzeneggar, Uma Thruman, Elle Macpherson, etc. Considering the cute image Alicia Silvertone has, it seems appropriate that Warner Bros would park Batgirl's Batblade beside the cute, feminine Tweety Bird VW Beetle.
