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 excercises. 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.
