Andrew Ritchie as an engineering graduate from Cambridge University used his knowledge to build the first Brompton folding bike in his bedroom – from which he could see the Brompton Oratory (hence the name). Ritchie persuaded 10 friends to invest £100 each so that he could build a prototype which was completed one year later. Brompton Bicycles was founded in 1976. Andrew Ritchie 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. Brompton has now produced well over 100,000 bicycles and in 2008 achieved 25,000 units for export to markets such as the Netherlands, America, Germany, Japan, and Scandinavia.
