Brompton Business Backpack 28L – Multi-Compartment Travel Bag with Front Carrier Frame (A/C/G/P/T Line)

The minimalist business backpack that slides onto your Brompton's front carrier — and lifts off as a full-size travel bag the moment you park. The frame stays on the bike, you walk away with the bag. Built for riders who want one backpack that handles the morning commute, the office, and the weekend trip.
