Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Brompton Waterproof Roll Top Large Frame in Copper

The Brompton Waterproof Rolltop Bag Large is a compact, waterproof solution designed to function as both a front bag and a backpack. It features magnetic shoulder straps that tuck away while riding and pull free in seconds, allowing for a seamless transition from bike to shoulder. The bag is designed around the way a Brompton is ridden, folded, and carried, ensuring every detail serves a purpose. Brompton's luggage system places the weight on the frame instead of the handlebars, ensuring the ride remains stable when carrying loads.

The rolltop opening adjusts to suit the load, while an air release valve allows for a precise closure.
