The Backpack Bicycle transformer is the ultimate combination of health and eco-technology.  The folding bicycle, designed and developed by Chang Ting Jen, does not appear to be available in stores yet, although the concept is irrefutably good. 

With the prototype weighing only 5.5 kg (much less than a traditional bicycle), and also doubling up as a hand cart, this is the perfect travel accessory.  This weight is also expected to be reduced when lighter materials are used in the future.
