I suspect that Beijing has more than 9 million bikes within the city limits.
I have often challenged that this cannot be “a fact – a thing you cannot change.” Surely a theft of one bicycle would make it 8,999,999 bicycles. Katie Melua didn’t respond to my query and has not done so in intervening years.
I doubt that within Beijing the net change in bicycles is in the order of 1. I also doubted that a bicycle census was even possible or that a reconciliation would be practical.
Therefore I contended and still contend that Katie had no idea of the number of bicycles in Beijing or how it could change. I also doubt she defined what a bicycle would consist of a complete machine or whether a complete set of components – sufficient to make a bicycle would be counted.
Therefore, I doubt the accuracy of her statement and her ability to make an accurate assessment.
