Bicycle sales up 350% in the UK last year, total usage in London up 91% over the last decade

Here's an article in Spanish I noticed on Meneame today about a huge increase in bicycle sales in London in 2009, the year when the economy was particularly bad. According to the article the bicycle market in 2010 increased to 698 million pounds, or 834 million euros / $1.1 billion (here's an English article on that).

In 2009 there was a 350% in growth of sales, apparently helped by the government's Cycle to Work program which gives tax benefits to those that are employed and rent a bicycle. Apparently the program works by taking a small cut in salary, and then after it's over the bicycle returns to the market at a reduced price.

Three more numbers: cycling in London has increased by 91% over the past decade, and for each new cyclist there is 423 euros (yearly?) in savings due to improvements in health, pollution and congestion. Also, for each euro spent on bicycles the UK receives 4 euros in benefits.
