The Brompton City Folder is a spacious and refined 25L Brompton front bag, designed for everyday commuting, urban riding, and travel. Compatible with Brompton folding bikes, including the Brompton G Line, it provides generous storage for a laptop, documents, and daily essentials without compromising the bike’s clean aesthetic.

Made from durable waxed cotton duck, this Brompton bag delivers reliable water resistance, while the stormproof drawcord closure helps protect contents in unpredictable weather. Internal organiser pockets keep valuables secure, while twin rear external pockets provide quick-access storage when riding. Off the bike, the removable and adjustable shoulder strap allows the City Folder to be carried comfortably as a satchel.

A practical, durable and stylish Brompton commuter bag, built for daily use.

Brompton City Folder is designed to fit the Brompton standard-size front carrier frame. This frame is required to mount the bag, is not included, and must already be fitted to your Brompton.
