The unique Brompton folding bike was designed and built in London in 1975 by Andrew Ritchie in his flat in South Kensington opposite the Brompton Oratory. Still made in London today, Brompton is making over 45,000 bikes per year and is the UK’s largest bike manufacturer. British folding bike company Brompton Bikes has recently expanded its operations, moving into a larger factory in west London. Around 80% of the 45,000 bikes it sells each year go overseas and over 1,200 parts go into the making of each bike.
