Travelling with your Brompton is made easy by its small folded dimensions. This means it fits into many car boots, and even counts as hand luggage on some airlines (please note: check this with your airline before travelling).
We produce the Brompton bag (B Bag) for transporting the bike on occasions when it is desirable to be able to pack down the luggage in which the bike travelled and pedal away. The B bag is a soft bag made of tough Cordura, it has a shoulder strap, handles and a steel plate in the bottom with castors so that the bag and bike can be rolled around. We regularly transport bikes around the world in B bags, without issue. For more information on this please see the Accessories Explorer section of our website.
We do not produce a hard plastic case and we would not recommend stowing a Brompton in a hard suitcase that has not been specifically designed for the purpose; if it is not suitably cushioned, doing so can potentially damage the bicycle. We recognise that there remains consumer demand for a more rigid case but we believe that the B Bag provides a measure of padded protection suitable for Bromptons in aircraft holds and on other long-haul journeys.
