Finely-engineered and elegant, the Brompton has a full-sized frame, made mainly of steel for strength and stiffness. It is designed to be practical and light enough to be genuinely portable; actual weight depends on model and configuration, but ranges from 9 – 12½ kg (20 – 28lbs). Brompton weights are true weights; unlike most bike manufacturers, they include the weight of mudguards, pedals, etc. in the figures – if it’s on the bike, they weigh it. The combination of a rigid frame and accurate alignment makes for efficient transmission of your energy and a lively, first-rate ride; countless owners use them on long journeys and for touring and many prefer the ride of a Brompton to that of conventional bikes.
