Though this bag does not stay attached to the bike, it offers more protection and fuller coverage (as well as a shoulder strap!) relative to the Quick Transit bag. Get this one if you have a small or medium bike and have straight handlebars. Get the other larger one if you either have a large frame or larger bars, such as h-bars.
This bag slightly longer overall than the large tikit bag, but lower in height.
Bike is quick folded and front wheel is left on. Bag is double sewn with 400 denier coated pack fabric. Shoulder strap and handles are made with polypropylene webbing. Handles are blue webbing. Zipper pulls are blue cord with zip cord clamps. Medium size Tikits with drop bars may need Large/ Large Bars bag.
Wt: 549 grams. Rolls up to: 4 1/2" diameter, 9" long
