Ortlieb Twin-city Urban 9L

"The Twin-City Urban 9L from Ortlieb is the perfect companion for all those who want to master everyday urban life both on foot and on the bike. This innovative bag combines the functionality of a bike bag with the style of a shoulder bag. It is made from robust and waterproof Cordura fabric, which is not only hard-wearing but also pleasantly soft to the touch. With a volume of 9 liters, it offers enough space for an A4organizer, wallet, smartphone, notebook and a water bottle, while remaining small enough to get through the day easily and carefree."
"Thanks to the intelligent QL2.1 hook system, the bag can be securely attached to the luggage carrier of your bike, with the shoulder strap stowed in a special compartment. After the ride, the bag can be transformed into a stylish pannier in one easy step by folding down the folding lid and concealing the bike hooks. This keeps the bag elegant and functional at the same time, without anyone immediately recognizing its dual function."
"Safety aspects are the top priority with the Twin-City Urban 9L. It is recommended to tighten the carrying straps before each trip or stow them in the product to avoid the risk of injury. In addition, the maximum load of 9 kg should not be exceeded in order to prevent material breakage. Regular checks of the screws after certain mileage are also important to minimize the risk of components loosening due to vibrations. The IP53 protection class guarantees additional protection against dust and splash water."
