This carrier bag with backpack function has a laptop compartment, is waterproof and can be removed from the carrier. Finally no more annoying elements on the back, as the bike suspension, unlike most 2 in 1 bike bags, is on the front of the backpack. The bicycle bag backpack combination has high quality zippers (YKK), 3 inside pockets, 2 outside pockets, a robust material and is 100% handmade and waterproof. The front of the bag is provided with a 28x40 cm reflector and creates perfect visibility for drivers. The shoulder straps of this bicycle bag can be stowed away in a large side compartment, lined with reflective material. It stands robustly on the floor because it has plastic feet. The inner floor is stable and foldable, so that a flat surface is created on the floor.
