Unboxing the Blackburn Under-Seat Bag
The Blackburn under-seat bag is a compact solution for carrying essential bicycle repair tools and accessories. It features a secure, Velcro strap system for attaching to the bicycle seat and frame. The bag itself is designed to be easily accessible, opening via a zipper for quick access to its contents.

Upon opening the bag, I found it well-organized with a dedicated space for tools and other items. The construction appears durable and water-resistant, which is vital for protecting contents from the elements.

Multi-Tool and Accessories Included
The Blackburn bag comes with a comprehensive multi-tool, including Phillips and flat-head screwdrivers, Allen wrenches (various sizes), and a star wrench. These are essential for on-the-go repairs. All tools conveniently fold neatly into the multi-tool itself for space saving.
Beyond the multi-tool, this kit includes two plastic tire levers to aid in tire changes, and a small, hand-powered pump for inflating tires. These are invaluable additions to any cyclist's emergency kit.
Additional Tool Kit and Considerations
I also demonstrated a separate, compact folding multi-tool which would be useful in addition to the Blackburn's included tool. It has additional tools like scissors and a bottle opener, making it more versatile than what was included in the bag itself.
One downside is the lack of storage space in the Blackburn bag; it's not large enough for additional supplies like extra tubes or a larger pump. I would therefore suggest using this bag in conjunction with another, larger storage option on your bike.
Final Thoughts and Conclusion
The Blackburn under-seat bag is a convenient and well-designed solution for carrying essential bike repair tools. The included multi-tool and pump are high quality and useful. However, the bag's small size limits its storage capacity.
It's best suited for carrying a minimal emergency repair kit, which means it’s more of a supplemental bag instead of a primary carry all. Consider using it in conjunction with a larger bag for extended rides or if you prefer to carry more supplies. For its size and included multi-tool, the Blackburn bag is a reasonable buy for its purpose.
