Every day, one-third of the people of Copenhagen ride their bikes to work or school. Collectively, they cycle more than 750,000 miles daily, enough to make it to the moon and back. And city officials want even more people to commute, and over longer distances.

So a network of 26 new bike routes, dubbed "the cycling superhighway," is being built to link the surrounding suburbs to Copenhagen.

 

Several innovations are being tested, like "green wave" technology, which times traffic lights to suit bikers. If you maintain a certain pace, you can ride all the way through into the city without stopping. There are also footrests with bars to lean on at traffic lights, and a bike pump every mile in case you have a flat.
