Hollywood’s favourite dad, Brad Pitt, knows how to give his kids a birthday present to remember.

“Brad took him into the garage and there the bike was with a bow on it. Maddox was over the moon and couldn’t wait to try it out. He was riding it around all day at the house, tearing up the lawn,” a source told British newspaper The Sun

It seems that the famous motorbike enthusiast has passed on his love for the sport to his son. Pitt has reportedly been looking for the perfect bike for Maddox since June before deciding on the Suzuki DRZ-125 motocross he purchased late last month.

But no motocross present would be complete without your very own backyard trail, or ‘grounds’ if you are the Jolie-Pitts. Pitt reportedly had a personal motocross trail built amongst the private woods at their Chateau Miraval in France.

“He was down at the house the other week and got the builders to dig him a muddy trail all through the woods and around the lake,” says the source, “Brad was just as excited as Maddox about it, though — he’s put in little jumps and puddles so they’ll get really muddy.”
