Bicycle and car production since 1950

FAT-BUSTING but not wallet-busting, the humble bicycle is an increasingly popular choice of transport. Around 130m bikes rolled off production lines in 2007 and even more are set to be made this year. Bicycle and car production grew pretty much in tandem in the two decades beginning in 1950. But since 1970 bike production has nearly quadrupled while car production has roughly doubled. Much of the recent growth has been driven by electric bikes; production has doubled since 2004, to 21m.
