Green types that like to ride their bike to buy groceries rather than having to drive to the store, but worry that their bike will get stolen will get a kick out of the Urban Folding Bicycle concept. The concept was designed by Hyuk-Jae Chang and won a bronze prize at the IDEA Design Awards 2010.
The basic concept is a normalish looking bike that you can ride around town with a chain and disc brakes. Once you get to the store rather than chain your bike to a post or bike rack, you simply fold it down into your own shopping card.
The cart has a push handle and a pair of baskets for your purchases. Once back outside you unfold the bike again and ride away. The only downside I see is that the baskets are a bit small. You won’t be buying many groceries at once.
