A Nelson trailbike rider has become an internet sensation after posting a video showing him being attacked by an angry ram.
Marty Todd's YouTube video, in which the surly ram known as Rambro prevents him from riding up a dirt track, has gone viral after being featured on CNN and Britain's Daily Mail website.
"I was riding my trailbike up a hill when I came across this grumpy old ram with huge horns," Mr Todd said. "It charged my bike then started attacking me, [he's a] surprisingly powerful animal."
Mr Todd said he couldn't turn his trailbike around as he was on a steep hill and if he did the ram would have charged him side-on, which could have broken his leg.
"This guy is known for his aggression and attacks for no reason, he's even attacked a group of pig-hunting dogs. In the end I had to pick up a branch and wave it in front of him, he didn't like the noise and backed off enough for me to make my escape."Mr Todd said Rambro was an Arapawa breed and an old pet that its previous owner couldn't control.
He let him loose on his large scrub and pine plantation a few years ago with his "missus and a son" and didn't come across him very often.
"But when he appears, I'm always on guard," Mr Todd said.
"He has severely bruised my leg when he headbutted me from the side on the bike and he has also charged me from behind when I turned my back on him once or twice."
While Rambro was a bit of a menace, he was also a "character and he is better than any guard dog".
