If you have this, you have everything – because the environmentally friendly, PVC-free Mineo Transformer Backpack 20 can be clipped onto the bike rack as a bicycle bag. It also serves as a comfortable business backpack and additionally features a trolley attachment function for your travel times. The bike backpack is mounted and removed from the bike rack via the adjustable Plug and Ride attachment rail, which is quick and easy to handle. The rail then simply disappears into the quick storage compartment when the bike backpack is put on. The spacious main compartment includes a sleeve for a 15.6" laptop as well as holders for pens and water bottles. An additional front pocket and a security pocket on the back keep your phone, documents, and papers easily accessible in the bike backpack. A super practical key holder elastic band on the padded shoulder strap makes locking the door a pleasure, and the dirt-repellent material is resistant to the everyday urban jungle.
