Heavy use of bicycling works best if the topography of the land is relatively flat. That’s why bicycling for commuting is very popular in the Netherlands and Denmark, given the majority of the population of these countries live in flat, low-lying areas.

My sister spent two months in England last year, and said bicycling is common, even among older people, who sometimes drive three-wheelers. But, as you said, it's relatively flat. She was there during a fairly pleasant autumn, and the cycling probably drops off during the winter.
