City cycling has changed a lot since Brompton first started cobbling folding bikes in London. Not only is there more traffic than ever but train rules are stricter, plus e-bikes have gone from novelty to normal.
The catch has always been weight. Most electrics are a pleasure to ride but a pain to carry, especially up some stairs or onto a packed carriage. Brompton’s answer has always been to make the whole thing lighter and smarter, without losing that fold-and-go routine it's known for.
