bike-in-a-bag.com offers a precision built, easy and fun to ride, folding bike, with a special dual purpose bag. The bag has a dual purpose. Firstly to carry the bike, using a handle and shoulder strap. Then when you are ready to ride, the bag coverts into a backpack to carry your stuff. So instead of struggling to balance a briefcase or shopping bag on your handlebars, or fitting a rack and panniers, you can carry it on your back using a highly visible rucksack.
