Topeak TrunkBag Rear Rack Bicycle Trunk Bag with Strap Mount

Product description

Semi-rigid construction and weather resistance: The bag pairs dual molded side panels with flexible 600 denier fabric to create a supportive, weather‑resistant shell that retains its shape even when fully packed for daily commutes or multi‑day rides.

Organized interior and exterior storage: Inside is a divided main compartment for separating tools and clothing, plus mesh side pockets and a dedicated rear pocket designed to hold a water bottle so essentials remain accessible while riding.

Tool-free, strap mounting system: Attachment uses integrated hook‑and‑loop fasteners that secure the bag to most rear racks. The system is designed for a secure, wobble‑free fit without tools or permanent mounting hardware.

Visibility and safety details: A reflective 3M strip and a built‑in light clip increase visibility in low light, while the bright yellow interior lining helps you locate items after dark or in dim conditions.

Carry options included: The kit ships with a padded shoulder strap and a sturdy carry handle, allowing comfortable off‑bike transport for errands, commuting, or tour stops.

Cons

Mounting is quick via integrated hook‑and‑loop straps and the bag stays stable on m

Reviews

  1. Z Z Ma 5/5

    Great pack!

    Spacious and well arranged. The adjustable divider and rear bottle pocket are my favorite features.

  2. Mary Grace Ross 5/5

    Rear bicycle bag.

    My husband really likes it and it carries everything he needs on his rides.

  3. Mateo 3/5

    Underwhelming value

    It straps securely to a rack but the main compartment is modest and the zipper feels thin. An expandable option would add useful capacity.

  4. Roy McKenzie 5/5

    Excellent quality bag

    Well made and the size is just right for my needs.

  5. Kensale77 5/5

    Solid trunk bag for light loads

    I own several bags from this maker. It mounts easily with the hook‑and‑loop straps and is ideal for snacks, a jacket and a smaller bottle. Very heavy locks or large bottles can make the straps slip, and frequent removal is a bit fiddly. If you want a quick‑release clip system, look for the clip‑in variant and compatible rack adapters.

  6. Michael Nelson 4/5

    Top quality—except the bottle ejection

    Excellent materials and build; fits my e‑bike rack perfectly. Lost a bottle on the very first trip, so I docked one star.
