Detailed Product Description:

QBag Tank Bag Magnet/Strap Backpack ST18 Waterproof

With FIDLOCK fasteners, it can be removed from the base plate in seconds and used off the motorcycle as a fully functional waterproof backpack.

Details:

  • Easy to load through the roll closure and absolutely waterproof
  • Large main compartment with viewing window and two slip pockets inside - one with access from outside through the waterproof zipper
  • Suitable for almost all tank shapes regardless of tank material (steel, aluminum, plastic)
  • Flexible base plate with 4 strong magnets and additional strap attachment
  • On a pure steel tank, the 4 strong magnets ensure secure hold - the rear removable straps are not needed, the front steering head strap can be used for "peace of mind"
  • On an aluminum or plastic tank, the pure three-point strap attachment is used (front steering head strap, 2x clickable loop straps at the back)
  • On models where only part of the tank is magnetic (e.g., rear steel tank, front plastic cover), the function of the magnets and the strap attachment can be combined for secure hold
  • On many sports models, for example, the attachment is done at the front with the steering head strap and at the back with the magnets - making handling, especially when refueling, much easier than with a pure strap tank bag
  • Can also be used as a tail bag with the straps
  • Can be quickly and easily removed from the base plate and reattached with 4 FIDLOCK fasteners
  • Depending on space conditions or preferences, the tank bag can be attached to the base plate with the roll closure facing forward or toward the rider
  • Can be used as a backpack without the base plate
  • Padded back with ergonomic shoulder straps
  • Side mesh slip pockets (e.g., for water bottles)
  • Other parts can be attached to the sides using the compression straps
  • Material: 75% polyester, 25% TPU

Review with rating of 3 out of 5 stars

Auch als Rucksack zu gebrauchen

Habe vor zwei Tagen das Teil bei Polo in Berlin gekauft. Grund: er ist eben auch auch als Rucksack zu tragen. Das ist für mich der Vorteil gegenüber anderen Tankrucksäcken. Ob tatsächlich 20 Liter Raum geboten wird ist zu bezweifeln. Das Befestigungssystem ist gut aber bei Befüllung nicht ganz einfach zu handhaben. Die vorderen Magnete könnten zumindest auf meinem Tank stärker sein, reichen aber aus, man kann eben auch die manuellen Schlaufen nutzen. Das Material könnte etwas wertiger sein.

Einfach auf den Tank legen fertig. Hält überaschenderweise echt gut.

Review with rating of 5 out of 5 stars

War sehr gut für den Urlaub

Ich habe den Rucksack als Hecktasche benutzt. War super. Einmal richtig befestigt, da verrutscht nichts. An den Raststätten schnell abgeclipt und als Rucksack verwendet. Super! Wasserdicht, alles trocken. Viel besser geht es kaum.

Sehr großer Tankrucksack für Reisen

Ist natürlich ein sehr großer Tankrucksack (siehe Bild), der aber durch die doppelte Funktionalität eines Rucksackes sehr gut für Reisen geeignet ist. Vor allem das magnetische Befestigungssystem ist sehr geschickt und macht es einfach aus dem Tankrucksack einen normalen Rucksack zu erhalten.
