Canadian artist draws pictures with his bike

A Canadian cyclist has turned doodling into a sport, by riding thousands of miles to make pictures on his GPS tracker.

Stephen Lund uses an app that tracks where he cycles, and draws the route onto a map.

He realised that he could use the app to make works of art when he celebrated the start of 2015 by cycling a route that spelled out 'HAPPY 2015!'

Since then, the cyclist's doodles have only got bigger and better.

Here are some of his best pieces:

Darth Vader

A mermaid

A rodeo rider

A dragon slayer
