If you want to live out a green lifestyle, getting around on public transport as well as a bicycle is a good place to start. Unfortunately, toting around your bike through subways and buses can get quite tiring if you rely on your hands alone, which is why the Folding Bike Bag comes in pretty handy. It sounds rather heavy at 9.5kg, but boasts a folding mechanism that keeps it small and handy as you tote it on your back. It takes all but two minutes to open it and turn it into a bike, allowing you to get around in a faster and more fashionable manner.
