|Dudley Dursley's racing bike|
- "Exactly why Dudley wanted a racing bike was a mystery to Harry, as Dudley was very fat and hated exercise — unless of course it involved punching somebody."
- —Harry Potter's impression of Dudley Dursley's birthday presents.[src]
There was a racing bike Dudley Dursley received as a birthday gift in 29 June, 1991. His cousin, Harry Potter wondered how Dudley would use it, since he was fat and hated exercise. In the summer holidays, the same year, while being first time out on his bike, he knocked down Arabella Figg as she crossed Privet Drive on her crutches.
