Forms of Alternative Transportation to Work?

puargsss asks: "For many people a bicycle is not a viable form of transportation to work due to lack of storage space. Are there any products out there suitable for transportation to a working environment (the ability to store them inside is essential), or a detachable/retractable set of wheels similar to heelys that are built for a working environment? I normally rollerblade for sport/exercise, but it is fairly unprofessional to show up in my workplace with the rather large and clunky traditional equipment. Any ideas?"
