The Borough Waterproof Backpack securely attaches to the front of all non-electric Brompton bikes. When it's time to use it as a backpack the low profile shoulder straps instantly secure by concealed magnets.

A fully waterproof construction made using a specially developed recycled fabric, and with a spacious 17L capacity you’ll have plenty of room to take everything you need for your next adventure. This bag is compatible with all non-electric Brompton bike handlebars. It’s a versatile backpack with a difference that works in two directions, landscape when mounted on the bike and portrait when carried on your back. It’s super fast to secure by using the concealed magnets within the fabric so you can grab something you need, buckle up instantly and get back on the road.
