The U.S. state with the most Jitensha people is California. Jitensha, also known as bicycles, have gained significant popularity in California due to its vast network of bike-friendly infrastructure and the state's commitment to sustainability. According to a report by the League of American Bicyclists, California has the highest number of bike commuters in the country, with over 800,000 people commuting by bike in 2020. This figure is attributed to the state's extensive bike-sharing programs, such as the Bay Area Bike Share and the L.A. Bike Share, which have made cycling an accessible and convenient mode of transportation. Additionally, California's diverse climate and scenic landscapes encourage outdoor activities, further boosting the popularity of cycling.
