Brompton Borough Roll Top Bag

No, the front carrier block is sold separately. You will need to have the block installed on your Brompton bike to attach this bag.

The bag includes a dedicated padded sleeve designed to hold most standard laptops. It is best suited for devices up to 13 inches, though slim 14-inch models may fit depending on their dimensions.

The bag is constructed from highly water-resistant fabric and features a roll-top closure, which provides excellent protection against road spray and typical city rain. While it is very weather-hardy, it is not fully submersible or waterproof.

Yes, this bag is fully compatible with Brompton Electric models. It mounts to the front carrier block just like it does on the standard folding bikes.

The detachable shoulder strap is designed for short-to-medium commutes and transitions. While it is functional for walking between the bike rack and your office, it is not padded, so it is best for lighter loads if you plan on carrying it for extended periods.

The extra load strap system on the exterior allows you to secure bulkier items—like a jacket, a yoga mat, or a helmet—that might not fit inside the 14-liter main compartment. It is a practical way to expand your carrying capacity without needing a larger bag.
