Copenhagen has set a goal to have half its daily commuters use bicycles to get around by 2015, according to a press release.
The effort is expected to help play a role in the city reducing its emissions by 80,000. The city already has 350 kilometers of bike trails and another 70 are under development, including biking lanes on roads.
American cities such as Portland, Ore., are trying to learn from Copenhagen's example.
Copenhagen's "bike culture ambassador" is speaking alongside Portland Mayor Sam Adams Oct. 29 at a forum about marketing bikes to the masses, according to bikeportland.org.
