Black Brompton Ortlieb O Bag

The Brompton Ortlieb bag, known as the O bag was initially introduced in 2010. It was the first collaboration between Brompton and German company Ortlieb - the most respected name in waterproof cycle luggage - just the job for the wet British weather.

The O Bag is designed with an integral fitting for fixing to the Brompton front carrier block. This allows you to quickly mount / remove the bag onto / off of your bike

This is the latest (redesigned in) 2016 model bag (with a more refined Brompton logo)

Note: The front carrier block is sold separately here.

Ortlieb has created this bag specifically to work with the Brompton front luggage system - so it's not really compatible with other bikes

The Brompton O bag comes with the finish and functionality you would expect from Ortlieb and is offered in a choice of colours:

Brompton O bag colour range:

Black / White
Black / Orange
Black / Lagoon Blue

New for 2017:

Black reflective

Brompton O-bag features:

On the outside:-

The O-bag is feature packed, starting with the carry handle mounted at the top of the bag - it's comfortable and has reflective braiding (which you only see at night) for greater low light visibility

The Brompton O bag comes supplied with a detachable shoulder strap (this should be removed when riding so that it doesn't catch on something causing rider injury)

Unlike other Brompton luggage, no rainproof cover is supplied - as it is not necessary due to the inherent waterproofness of the Ortleib design

There are two removable roll top bags (rolling the top makes them almost 100% waterproof) large enough for iPhone / keys etc which attach to the back of the bag

One of the roll top bags has the ability to clip on the shoulder strap (the same strap used for carrying the complete bag) - turning it into a neat waterproof purse / man bag - ideal for evening use when away travelling

The fixing for connecting to the front carrier block is an integral part of the bag (rather than using a detachable frame like other Brompton bags)

On the inside:-

The O-bag has a laptop sleeve at the rear of the bag for maximum protection - this is capable of taking a 15 inch laptop

A handy key clip allows you to use the bag as a key safe too - the key clip attaches with a fastener, so you can use it as a key ring

Zip up and velcro pockets allow for you to store items securely and in different pockets to keep your daily life organised


Capacity: 20 litres (approx)

Dimensions: 500 mm (w) x 300 mm (h) x 150 mm (d)

Brompton front luggage options are based on the Brompton 'Front Carrier System'. Luggage is attached via a frame that latches securely onto a tapered block. It takes a second to attach or release your bag and the load is attached directly to the main frame - with little effect on steering.

Brompton Ortlieb O-bag Compatibility: 

Brompton O bag handlebar compatibility - all types

The O Bag is compatible with all handlebar types - though when used on the S-type or straight / sports handlebar equipped Brompton you should not over-fill as this could interfere with the steering.
