Designer Gosha Galitsky has created a prototype for a foldable bike. Now I know that there have been other collapsable bikes, but this one is different. When fully collapsed, the Briefcase Bike is almost entirely self contained. That way there aren't any loose wires, wheels, or gears to attack you or anyone you happen to walk by when carrying the bike. This makes it much easier to transport around both walking and on the bus.
The bike's currently stuck in the prototype phase, but hopefully a nice investor will help fund this so that Gosha can redesign it to look a little more like that Cannondale Jackknife. That way I won't be entirely embarased to ride it in public. Make the jump to see someone actually riding the Briefcase Bike as well as some of the concept drawings.
