In parts of Europe, there were declines in the use of bicycles after World War 2.
With the notable exception in the Netherlands, most countries began to focus their transport spending on building roads or rail throughout the second half of the 20th century. In the Netherlands, in the 1960s it was evident cycling did begin to decline. By 1970, the car was displacing the bicycle in most Dutch cities. However, it was evident that motor deaths began to become a leading cause of death for young people, which led to a reemergence of the importance of the bicycle in the Netherlands as a means for transport. Major campaigns began pressure politicians to develop specific infrastructure that segregated cyclists from motor traffic. This led to one of the first nation-wide master plans for cycling that focused on developing nation-wide bike routes and protected areas. The led to also dedicated bicycle garages, changing facilities, and parking areas throughout the country.
In the 1980s, what began as mainly an upper class interest in health and fitness in the United States, began to renew interest in cycling. While overall, the number of adult cyclists were low in the United States, weekend, recreational use began to make a comeback among some adults. In the 1990s, renewed interests in bicycle racing also helped Americans once again take more interest in cycling. During the first decade of the 2000s, it was high oil prices that made urban cycling become more popular in US cities. Dedicated bicycle lanes began to reappear. The rise of oil prices, high traffic, coupled with increased interests in health, with obesity becoming a major problem, has now led to cycling being of high interest in many countries in Europe, the United States, and East Asia. The biggest recent trends have been urban communities introducing docking stations and dock-less bicycles as part of their urban transport plans.
