Designed for cyclists who need a large-capacity, multi-mode carrying solution for commuting, touring, and mountain biking, our Waterproof Bicycle Pannier Trunk Bag mounts securely to your rear bike rack tail seat and converts instantly to a shoulder bag or hand-carry bag — giving you three carry modes in a single bag.

Includes a detachable shoulder strap with clip fasteners. Sold as a single piece. Black. 0.74kg. $29.00.

Waterproof Oxford Cloth; 3-in-1 Rear Rack Tail Seat, Shoulder, and Hand Carry; Expandable Side Panniers; Reflective Safety Strip; Multi-Compartment Organization

Waterproof Oxford Cloth — Keeps Your Gear Dry Through Any Ride: The bag is constructed from waterproof Oxford cloth that repels rain and moisture from the outer surface — protecting your belongings during wet commutes, trail rides, and touring in variable weather. Oxford cloth is a durable, tightly woven fabric that resists abrasion and maintains its waterproof performance through regular daily use, making it a more durable and reliable choice than coated nylon alternatives for long-term cycling bag use.

3-in-1 Carry Modes — Rear Rack Tail Seat Mount, Detachable Shoulder Strap, and Top Handle: The bag mounts directly to your rear bike rack tail seat for on-bike carry, then detaches and converts to an off-bike shoulder bag using the included detachable shoulder strap with clip fasteners — or carries as a hand bag using the padded top handle. This 3-in-1 carry system means you never need to transfer your belongings to a separate bag when you arrive at your destination: the pannier trunk bag itself becomes your carry bag for the rest of the day.

Expandable Side Panniers — Significantly Increase Capacity When You Need It: Two side pannier panels fold out from the main body of the bag to dramatically expand the total carrying capacity when you need to carry more gear — for touring, grocery runs, or multi-day trips. When not needed, the panniers fold flat and zip closed against the main body, keeping the bag compact and aerodynamic for everyday commuting and lighter loads. The pannier design also improves stability on the rack by distributing weight symmetrically on both sides of the bike.

Multi-Compartment Organization — Main Compartment, Front Pocket, and Side Pockets: The main compartment features an expandable top section with dual-pull zippers for wide, easy access to your primary gear. A front zipped pocket provides quick-access storage for items you need frequently during the ride — phone, keys, snacks, wallet. Side pockets on both sides add additional organized storage for smaller items. The compartment layout keeps your gear sorted and accessible without unpacking the entire bag to find what you need.

Reflective Safety Strip — Visibility in Low Light and Night Riding: A reflective strip runs across the front face of the bag, catching headlights and ambient light to make your rear end more visible to following traffic during evening commutes, pre-dawn rides, and low-visibility weather conditions. Rear visibility is a critical safety factor for cyclists riding on roads and shared paths — the integrated reflective strip adds passive safety without requiring batteries or maintenance.

Padded Top Handle and Detachable Shoulder Strap — Comfortable Off-Bike Carry: The padded top handle provides a comfortable grip for hand-carry between bike and destination. The included detachable shoulder strap clips securely to both sides of the bag and adjusts to your preferred length for cross-body or single-shoulder carry. Sold as a single piece. Black. 0.74kg. Suitable for road bikes, mountain bikes, commuter bikes, and any bicycle fitted with a standard rear carrier rack.

Frequently Asked Questions about the Bicycle Pannier Trunk Bag

Q: Does it fit all rear bike racks?

A: The bag is designed to mount on standard rear bicycle carrier rack tail seats. Compatibility depends on the width and rail spacing of your specific rack — most standard commuter, touring, and mountain bike racks are compatible. Check your rack dimensions against the bag’s base before purchasing if you have a non-standard rack.

Q: Is the shoulder strap included?

A: Yes. A detachable shoulder strap with clip fasteners is included in the package. It attaches to both sides of the bag and is fully adjustable for length.

Q: Can I use it in the rain?

A: Yes. The waterproof Oxford cloth outer construction repels rain and surface moisture effectively for typical cycling conditions. For extended heavy rain exposure, consider using a rain cover over the bag for maximum protection of the contents.

Q: How do the side panniers work?

A: The side panniers are zipped panels attached to both sides of the main bag body. Unzip them to fold them outward and expand the carrying capacity significantly. Zip them back flat against the main body when you want a more compact profile for lighter loads and everyday commuting.

Q: What is the weight of the bag?

A: The bag weighs 0.74kg empty — lightweight enough to carry off the bike as a shoulder bag or hand bag without adding significant weight to your daily carry.
