An expandable bicycle trunk bag keeps cycling essentials together on your rear rack and adds side storage when a trip calls for more room. The ROCKBROS design conceals fold-out side panniers behind zippers, so you can expand the storage without carrying separate bags.
A cushioned interior and adjustable dividers help organize tools, clothing or camera equipment. A hand strap and shoulder strap make the bag easier to take with you after parking the bicycle. The outer bottle pocket uses a tightening cord, and a rear attachment point accepts a separate taillight.
