Model

Most Brompton front bags are small. Great for quick trips, not so great when you actually need to carry things.

This roll-top bag gives you 27.5 litres of space, a dedicated laptop compartment, side pockets for quick access, and a rain cover — all on the front of your Brompton. Off the bike, it works as a shoulder bag or backpack. It's the bag for people who ride to work, not just around the block.


How it works

The bag clips onto your Brompton front carrier block — the standard mounting system used on all Brompton lines. If you already have a carrier block, choose Set 1. If you don't have one yet, choose Set 2 which includes a compatible block.

Important: this bag requires a front carrier block. If your bike doesn't have one and you order Set 1, you won't be able to attach the bag. Not sure if your bike has a carrier block? Check the front of your frame just below the handlebar stem — if there's a black plastic block with two holes, you're good to go.


Key features

  • 27.5L capacity — main compartment (22.2L) + front pocket (1.7L) + back pockets (3.6L)
  • Laptop compartment — fits laptops up to 16 inches
  • Roll-top closure — expands as needed, seals out dust and light rain
  • Side pockets — quick access for your water bottle, phone or tools
  • Retractable hook — pull-out steel cable hook (up to 60cm) for hanging your helmet or keys
  • Rain cover included — hi-vis yellow with reflective strip, fits over the whole bag
  • 4 carry modes — on the bike, by hand, shoulder bag, or backpack
  • Replaceable UK flag patch — velcro-mounted, swap it for your own if you prefer

Honest note on backpack mode: it works, but it's not comfortable for long walks. This bag is at its best on the bike or as a shoulder bag.


Available variants

  • Set 1 — bag + frame + straps + rain cover + hook + UK flag patch. Choose this if you already have a front carrier block on your Brompton.
  • Set 2 — everything in Set 1, plus a compatible 2-hole carrier block. Choose this if your bike doesn't have a carrier block yet.
