There are three levels of protection for your Brompton:

Cover & Saddle Bag: The lightweight option, stored in a pouch which hangs from the back of the saddle - a thin cover which drops over the bike, with a drawcord at the bottom.

B-Bag: A padded bag with a solid base, castors and a shoulder strap - rolls up for storage.

Hard Case: The ultimate protection, with foam padding, castor wheels, locking catches and a pulling handle.
