The T-Frame Backpack is a small bag that can be connected to a bicycle frame or worn as a backpack. This allows the user to travel without having to wear the backpack on his/her back while riding a bicycle. The bag provides room for bicycle locks, keys, phones, glasses, a water bottle, snacks, and small riding gear. The bag is made of water resistant heavy weight nylon cordura, reflective 3m material, and nylon straps.
