The bicycle briefcase. The medium-sized rear bag Bayreuth M, designed in a briefcase format, is made from robust, 100% recycled polyester material with a textile look, is waterproof welded, and completely PVC-free. A 13" laptop fits well protected in the padded compartment alongside other A4 documents that find space 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 adjustable Plug and Ride mounting rail allows the bag to be easily attached and removed from the bicycle rack (up to 16 mm diameter) using the QMR hooks. 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 conveniently carried by hand or with a well-padded shoulder strap. Reflective elements on the front and sides enhance visibility. The bicycle 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 standards. 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.
