More suited to commuting around Croydon than cutting across the Cotswolds, Brompton's Metro Waterproof bag is inspired by a messenger bag.

Our take on the Brompton Metro Waterproof Bag - Large.

We ship accessories Monday - Friday and aim to dispatch all orders within 2 days of receiving them. Free shipping orders are sent with Royal Mail and for bulky items, we may use DPD (at no extra cost).

Bikes delivery

In stock bikes are usually shipped within 14 days of you ordering as they undergo a Pre Delivery Inspection before dispatch. Bikes are delivered by DPD who provide a delivery window via text message on the day. Delivery of electric cargo bikes costs £40. This service is available to all mainland UK postcodes. Click and collect for electric cargo bikes is free.

Click & Collect

We can arrange for all items to be collected from store. For items other than bikes this usually takes 2 - 4 working days. Bikes can take up to 14 working days to be available. We’ll let you know when items are ready for collection. Please bring a form of ID and a bank card with you when you pick up your order.


We accept returns on orders up to 14 days after the items arrive with you. All accessory returns should be in saleable condition and be sent to our Hackney address with a note which has your name and order number on it. Refunds are processed within five working days.

Product Description

At 20 litres this bag should be enough to carry the essentials (plus a bit extra) to work and back. And because it is waterproof it'll happily repel water mile after a winter mile. Away from your bike an integrated shoulder strap has you covered.
