Anti-gravity motorbike
From Tardis Wiki, the free Doctor Who reference
The anti-gravity motorbike was a vehicle used in the Anti-Grav Olympics by the Doctor. After using it, he put it in his TARDIS' garage. The Eleventh Doctor hacked into a Spoonhead, which used the motorbike to fly up the side of the Shard in London. (TV: The Bells of Saint John)
