Unfortunately I could not keep this bag, because of my e-bike handlebar was no place for mounting (E-Bike with Bosch Intuvia display). In the first case delivered lacked the brackets that are mounted on the handlebars. After a complaint was then a complete shipment (many thanks to the great Amazon live chat). The bag made a very stable and good impression on me. Man opens this so that you can daily directly from the saddle and not one would have to fold the lid first widely over the handlebars. The Case for a map can be attached by Velcro. The strap was long enough. The content volume was 7 liters very spacious. Have this bag reluctantly returned because unfortunately they took care not to my 2.Rad because the handlebar was too thin and I found no adapter or Ausfüllteile) If the bag is fitted to one of my wheels, it would certainly become 4-5 stars.
