We could all do with a few more bike riders and a few less car drivers here in the US.
Biking helps you exercise (great), save money (great), and frees up the roads for car drivers like us who make others ride bikes to lessen traffic (awesome).
To help cities deal with the increase in bikers, the Cyclepod allows 8 bikes to be store vertically in a small 2 meter diameter. A lot full of these could accommodate almost an order of magnitude more people than with autos. The Cyclepod also lets you lock both the frame and the front wheel to prevent theft, something bike riders are always worried about.
