I’m an avid cyclist, traveler, food-lover, and owner of Eat Bike Travel. A Pair of Plastic Jelly Flats: I don’t pack these every time, but they’re always with me on tropical trips. I love to travel with my bike but the whole bike bag/box thing is an issue — they’re really cumbersome and HUGE. I wish there was a bike bag/box for travel that would fold down small enough to fit in a backpack when not in use. Once, at a Travel Massive meetup, I met a guy who was trying to develop a vest that could replace a carry on.
