Brompton C Line

The Brompton C Line is the classic model of the British folding bicycle maker Brompton, which describes it as the original icon and the original folding bike. It is a steel-framed bicycle on 16-inch wheels with Schwalbe Marathon Racer tyres, offered with four or twelve gears, a low, mid or high handlebar, mudguards, a folding pedal and a front luggage block. The maker says it folds in under 20 seconds, and the listed weight starts at 11.35 kilograms. It is priced from 1,449 pounds. It carries the hinged frame and compact fold that English Wikipedia says has stayed fundamentally unchanged since Andrew Ritchie's patent of 1979.
