The briefcase for bicycles. The medium-sized rear bag Bayreuth M, designed in a briefcase format, is made from robust, 100% recycled polyester material with a textile look. It is waterproof, fully welded, and completely PVC-free. A 13" laptop fits securely in the padded compartment, alongside other A4 documents in the main compartment. The bright interior material ensures good visibility: a key holder, a padded phone pocket, pen holders, and a loop for inserting a water bottle complete the interior features. The bag is mounted and removed from the bicycle rack (up to 16 mm in diameter) using the adjustable Plug and Ride attachment rail with QMR hooks, making it quick and easy to handle. A small padlock can be used to secure the bike bag directly to the QMR hook. The small feet on the bottom provide stability, and the bag can be comfortably carried by hand or with a well-padded shoulder strap. Reflective elements on the front and sides enhance visibility. The bike bag is produced in a climate-neutral manner at the VAUDE headquarters in southern Germany using high-frequency technology, featuring a clear design and high-quality Made in Germany craftsmanship. Emissions from materials, manufacturing processes, and shipping have been comprehensively assessed and systematically reduced. Currently unavoidable emissions have been fully offset through the independent non-profit organization myclimate. The VAUDE Green Shape label stands for an environmentally friendly, functional product made from sustainable and bluesign® certified materials.
