Backpack or bike bag? Both. The Cycle 28 is the ideal companion for commuters who want a secure fit for their bag on the bike during the ride, but also wish to carry it as a backpack on the train, bus, or at university. The bag is attached to the luggage rack using QMR hooks that can be locked, and can be quickly transformed into a backpack. To do this, the two vertical zippers are opened, and the entire attachment system is stored in a compartment that closes with Velcro. The conversion function is explained in a few steps on a sewn-in, easily removable label. However, this clever backpack-bike bag combination offers even more. Compared to its smaller sibling, the Cycle 20, it has a significantly larger main compartment that can accommodate A4 documents, a water bottle, snacks, and even a change of clothes. A separate, zippered, padded compartment fits laptops up to 15.6". A diagonal-opening compartment that spans the entire front features a mesh organizer for a phone, keys, and wallet. Additionally, there is a flat mesh pocket on this compartment for quickly storing magazines or wet clothes. Two side compression straps, a helmet holder, and attractively integrated reflective elements complete the comfort features.
