He was not seriously injured, St John staff said.
Duty manager Trudy Taylor said the ambulance attended but the man was left at home with his family as he did not need to be taken to hospital.
Police blocked off the section of the road while the cyclist lay in the street awaiting an ambulance. Bystanders comforted him following the accident.
The cyclist was not wearing a helmet when the 11am accident happened and Mr Patching said he was "lucky" his injuries weren't more serious.
"It's very, very lucky he didn't come out with more serious injuries."
It didn't take "much of a bang on the head" to do more damage.
Police wanted to remind cyclists to always be wearing helmets.
