Carrying everyday essentials in a backpack can make commuting hot and uncomfortable. The RideMate waterproof bike rear rack bag provides lightweight, expandable storage for work items, clothing, shopping and daily cycling gear without adding weight to your back.
Its roll-top design expands to 16L, while the welded 600D polyester and TPU-laminated construction helps protect your belongings during wet rides. Adjustable hook-and-loop straps allow quick, tool-free installation, and the included shoulder strap makes the bag easy to carry when you leave the bike.
The adjustable roll-top design expands to a practical 16L capacity, providing space for commuting essentials, clothing, shopping and touring gear. Additional pockets help keep smaller items organised and easy to reach.
