Well for the last 3 years about 300 million bicycles were produced Worldwide (Bicycle Statistics: Usage, Production, Sales, Import, Export). So to approximate, I would say that there are probably...

( this is not exactly accurate but as of this year) In china there are 540 millions and the U.S. about 103 millions

Three wildly different answers have been given: 1,421,000,001 512,145,754,102 Probably about 150,000,000 or 100,000,000 exactly infinity more are being this very second

1.1 billion
