When you ride a bike, you see all sorts of things – crazy drivers, crazy pedestrians, crazy cyclists giving you a bad name and crazy potholes to name just a few.

But when Victorian cyclist Ben Vezina took to two wheels for a leisurely park ride recently, he probably wasn’t counting on seeing this somewhat unnerving sight.

(Language warning)

The clip was filmed at Hawkstone Park, about 20km north-east of the Melbourne's city centre, and while Ben was clearly nervous about riding through the pack of eastern grey kangaroos, he did so safely and without incident.

“Kangaroos are nice animals who don't gather like hordes and attack people,” he wrote under the clip posted to YouTube.

“They coexist with people and never attack them. This video is proof. More cyclists and pedestrians should come alone to Hawkstowe Park.”

Of course cyclists have been less lucky with the hopping beasts in the past, as former Australia cricketer Bronwyn Calver found out to her cost earlier this year.

Calver was riding close to the Capital Circle in Canberra at dusk when a kangaroos jumped out of nowhere and sent her flying.

Calver escaped serious injury, but did require eight stitches to a gash on her knee.

"I've never seen a kangaroo in that spot. You certainly see kangaroos further along that route when you get closer to the bush behind the suburbs," she told Fairfax media at the time.

"They sit there, watch you and you slow down just in case they decide they are going to move at once but I've never ever had a close call at all."
