Increase the portability of the Strida Folding Bike with the durable Strida Bag. Able to be slung across a shoulder with its adjustable strap, the Bag is made from ripstop nylon. Used in hot air balloons and kites, ripstop is a lightweight, water-repellant nylon. Woven with an extra thread in a crosshatch pattern, ripstop nylon is supremely resistant to tears.
