The 39-year-old 'Dark Knight' star took the decision to give up on his risky "obsession" of bike racing following concerns from wife Sibi Blazic and eight-year-old daughter Emaline who seemed worked up post the death of 'The Fast and the Furious' star Paul Walker in a car accident last November, reported Contactmusic.
"Since Paul's death, she's totally freaked out. Sibi doesn't want Christian racing at all and that's going to be a real struggle for him," a source said.
"Christian is obsessed with racing foreign bikes, but he adores Sibi and hates seeing her so worked up over what happened to Paul.
Since the birth of his daughter, the actor had limited his bike riding only to race tracks and that also under controlled supervision.
"Sibi has always had a problem with Christian's love of fast bikes. She stopped him from riding them in the streets shortly after the birth of Emmaline eight years ago.
"Since then, he has limited his riding to the race track under very controlled conditions," the source added.
