The Folding Bike
Bikes are great. Great exercise, no fuel costs, very maneuverable, and no emissions. The biggest drawback to using a bike is its size. Most bikes are too big to take inside, Watch how easy it is to fold up.
This convenience is not cheap. The bike will retail for about $1400. At that rate, I hope you love bicycling, because you won't have money for anything else! There are a total of five models of foldable bike from STRiDA for different size riders and different purposes. Available in spring 2009.
