Maddox Jolie-Pitt is ready to motor!

The eldest child of Angelina Jolie and Brad Pitt turned 11 on Sunday Aug. 5, and he received a doozy of a gift: His very first motorbike, ordered by Pitt, 48, at HGB Motorcycles in Ruislip, Germany.

The big brother to Pax, 8, Zahara, 7, Shiloh, 6, and 4-year-old twins Vivienne and Knox now has his very own Suzuki DRZ-125 motorbike -- which can reach a top speed of 50 miles per hour -- a rep confirmed to E! News.

A source tells Us Weekly that Pitt first visited the shop back in June, but hesitated on the splurge. "He wasn't sure of the safety and wanted to think about it," the source explains. After a chat with fiancee Jolie, 37, "an order came through for the Suzuki. It's a great bike for a kid to have as his first -- it's a junior dirt bike, so very safe, low powered but still very fun."

E! News reports that Pitt "wants the boys to be able to ride [bikes] on private land . . . He has a real passion for bikes which he's like to pass on."

Maddox (whom Jolie adopted in Cambodia before her romance with Pitt began) certainly shares his mom and dad's daredevil tendencies. Last September, he accompanied Jolie during her flying lesson in Hampshire, England.
