This robust, sustainable and resource-saving bag model is a loyal and extremely versatile everyday cycling companion — whether for a trip to the office, a trip to the gym or as a pannier bag for a tour. All-in-one: pannier bag and backpack in one As with all practical hybrid models from Spleen Berlin, Bob can also be converted from a backpack to a bicycle bag securely attached to the luggage rack of the bicycle in just a few simple steps. With the bicycle backpack as a spacious luggage bag, you can cycle around the city flexibly and unburdened — after parking the bike, Bob simply hikes onto your back as a comfortable, well-fitting backpack, so that you still have your hands free. Particularly practical for trips and tours, when you want to stop your bike during a hike.
