The concept of bike sharing is perfect for densely-populated cities and has been successful and extremely popular in international cities such as Amsterdam, Paris, Barcelona, Stockholm and Melbourne.

In the states, Washington, D.C. and Boston have a system on place. Another major city is slated to begin having free spinning classes in their streets, as low cost use of bikes become a reality in New York City next summer.

Anyone who wants some wheels will be able to pick up one of 10,000 bikes at one of 600 (solar powered!) stations during any day or time. The bike can then be left off at a drop-off station near a personal destination. The low cost option of traveling around a city is not only environmentally sound but will save on the cost of a gym membership.

In the 2009, “The Proposal”, Sandra Bullock made an impression on her exercise bike. In fact, she devotes much time for daily riding on a bike to stay in shape, especially when she is not filming. Her latest cinema venture will be released in January with co-star Tom Hanks, titled “Extremely Loud and Incredibly Close.”

Sandra Bullock happens to adore the Michael Kors Silicone Chronograph watch when cycling. It has been seen many times adorning on her wrist.
