A man shown in a video "dooring" a cyclist on a city street has come forward to police.

Victoria Police confirmed a 65-year-old Brighton man has spoken to officers after a video showing him leaving a taxi through the passenger-side rear door in Collins Street, Melbourne, on Monday.

The cyclist, who had cameras attached to both her helmet and handlebar, captured the accident and the passenger's reaction.

The cyclist is seen asking the taxi passenger for his details after the collision, but both he and his travelling companions refused to give them.
