Brad Pitt Motorcycle Touring Iceland, Pax's Accident Fresh in His Mind

Brad Pitt‘s getting back on the horse, or in this case, a hog — taking a motorcycle adventure just weeks after an e-bike accident landed his son Pax in the hospital.

TMZ got video and pics of Brad in Iceland, prepping for his ride and covering his face with a black ski mask for warmth — it’s summer on the Nordic island, but far from balmy — then slipping on his helmet and mounting up.

Check out the video — he pulls out of the parking lot and throttles up his speed, rolling out through the city.

BP leaves the lot accompanied by a couple other bikers … unclear where exactly they’re going, but they don’t exactly seem like a fearsome motorcycle gang.

Pitt’s motorcycle trip comes just a few weeks after Pax’s nasty accident while riding an electric bike in Los Angeles. TMZ broke the story … Brad and Angelina Jolie‘s son slammed full force into a stopped car in rush hour traffic.

Pax wasn’t wearing a helmet at the time, and was briefly hospitalized with a minor brain bleed before doctors released him.

Sources with direct knowledge told us Brad was very worried about his estranged son … and, while they didn’t have any direct contact, people around Pax gave Brad consistent updates.

Of course, there’s a big difference between father and son’s ride locations and equipment — but Pax’s ordeal has to be on Brad’s mind.
