What is the number one bike city in the US?

Could you elaborate on what criteria are being used to determine the "number one bike city" in the United States? Is it based on the number of bike lanes, the percentage of residents who commute by bike, the amount of cycling-related infrastructure, or perhaps a combination of these factors? It would be helpful to understand the methodology behind the designation so that we can have a clearer picture of what makes a city stand out in terms of biking.
