The Brompton Cline High Folding Bike is a Classic All-Steel Foldable Bike. The 6 speed do-it-all workhorse – geared up to go further. Covers all contours, at home or further afield.Invented by our founder, Andrew Richie, in 1975, expertly engineered to transform the bike into a small, locked package a little larger than its wheels - all in under 20-seconds. Nothing folds like a Brompton folds.Bromptons are made different. We engineer an efficient solution for moving around the city and beyond. Ours is a bike that does more than the obvious, it answers problems owners say they didn't know they had. ‘You don’t get Brompton until you get a Brompton.’Brompton Cline High Folding Bike HighlightsMain Frame Precision drawn heat-treated steel tubing with hand brazing and selected auto-brazed jointsRear Frame Hand brazed cold-formed micro-alloy steel tubingFork Steel brazed fork
