The festival, which runs from Oct. 22 to 26, is made up of more than 100 films and videos focused on the environment.

Hahn, director of Tales of a Yellow Bike, decided to focus her film on the importance of bicycles as the main mode of transportation after learning about Toronto's BikeShare program, which ran from 2000 to 2006.

The bicycle lending program, in which hundreds of members could rent yellow bikes at 16 hubs in the city, shut down due to insufficient funding.

"I wanted to do a film about bike sharing programs across the world," Hahn said. "Our first days of shooting happened when BikeShare shut down in November 2006."

Tales of a Yellow Bike tells the story of bike share programs in Europe, North America, Columbia and China and the perception of bicycles in various countries.

"In Amsterdam they have so many bikes they don't know what to do with them all," Hahn said. "In China they have 470 million bicycles. In China, bikes used to be the only mode of transportation. In Bogota, Columbia there are hundreds of kilometers of bike lanes."

So why is Toronto so slow at jumping on the bicycle wagon?

"The one key problem is the geography of living in north Toronto," Hahn said. "A bike share program can only work in the downtown core. And a lot of automobile drivers don't respect cyclists in Toronto. If we got more bikes on the street it would be safer for cyclists because there would be traffic changes, people would be slowing down more. I want people to consider bicycles as transportation, not just recreation."

Hahn, the founder of Symmetree Media, has directed and produced programming for Book Television, Bravo!, Canadian Learning Television, CTV, Discovery Health Channel Canada, Documentary Channel Canada, Knowledge Network, SCN and TVOntario. She has also edited more than 40 independent films.

Tales of a Yellow Bike will be shown at Innis Town Hall, 2 Sussex Ave., near Avenue Road and Bloor Avenue, at 11 a.m.
