     More and more people like bicycling and it is no surprise. It is fun, healthy and good for the

worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

around you. Stopping and getting off a bike is easier than stopping and getting out  of your car.

You don't even have to ride all the way.
