New York city boasts one of the greatest public transportation systems in the nation. They may soon also be able to claim the largest bike share program. Following models based in Paris, London and Washington D.C., riders with a ticket can rent a bike at one station, ride it for as long as they wish and return it to another station--on the other side of town. In just a few months, New York City plans to roll out a 24-hour system including about 10,000 bikes. They’re seeking a private company to start up the program with wireless technology, GPS tracking devices and solar-powered bike stations, but the city plans to share in the profits. How will a bike-share change New Yorkers' transportation networks? And, proponents of the plan say New York's flat landscape and high density make it a perfect candidate, but could something like this ever work in Los Angeles?
