In the UK cycling was very popular until the end of the 1950's but it really lost out to our love affair with the car. Regaining a culture where cycling is seen as an everyday part of life requires time and effort. Of course in some British towns it never really went away - just look at Oxford and Cambridge. In other places, where the car has been king for many decades, it takes more time.
Cycling is an activity which more and more young people are getting involved with, whether they are using their bikes to get to school or work, socially, or cycling as a sport. Cycling is cheap, it's quick, and it makes you look and feel great!
Cycling also offers a sense of independence, of being able to get up and go wherever and whenever you want. That's invaluable.
