Ambulance officers have treated 14 cyclists over the past 24 hours after separate bike accidents across Melbourne.
Cyclists were left with broken arms and collarbones after the accidents, seven of which occurred during the morning peak hour.
The spate of bike accidents follows another three last night, which left three children hospitalised.
Intensive care paramedics Rohan Miniken said the most serious crash occurred about 8.30am when a 48-year-old man fell from his bike onto tram tracks in Commercial Road at Prahran.
"He struck his head on the road but thankfully was wearing a helmet," he said.
"The helmet had significant damage, and if he wasn't wearing that he probably would have fractured his skull.
"The man has bruising and swelling to his side and may have fractured some ribs and has a collapsed lung."
The cyclist was given pain relief and fitted with a neck brace before being taken to The Alfred hospital in a stable condition.
In a separate accident, a 34-year-old man fractured his arm when he tried to avoid a collision and his tyre became lodged in tram tracks.Read More, 14 Cyclists Injured in Spate of Accidents
