All Bromptons are designed and built in their factory in West London, England. Brompton is one of only two major frame manufacturers still based in the UK, and they have been in full production since 1988. The company has come a long way since its initial production facility in a railway arch, and the current site occupies 22,000 sqf.
A key feature of the Brompton is the compactness and practicality of its fold. With a little practice, this is achieved without any difficulty in 10 - 20 seconds. The dimensions of the folded bike are: 585mm high x 545mm long x 270mm wide (23" x 21.5" x 10.6").
When folded, a Brompton stays locked together, making an extremely compact package little larger than its wheels. The folded package may be picked up without any risk that the bike will unfold - reassuring when running for a train or handing it to a cloakroom attendant!
There are no projections or loose parts with the folded package and, using the frame or saddle as a handle, it carries like a small suitcase, lightweight and easy to manage. The fold is designed to keep vulnerable parts, like lights and cable-runs, out of harm's way and, by folding them in, to keep the greasy chain and gears away from clothing and luggage. Small rollers allow the bike to be pushed into inaccessible corners.
