Which US city has the most cyclists?

As a keen observer of urban mobility trends, I'm curious to know which US city boasts the largest cycling community. With the rising popularity of cycling as a sustainable and healthy mode of transportation, it's fascinating to consider which metropolitan hub is leading the charge in terms of cyclist population. Is it a bustling metropolis like New York or San Francisco, renowned for their bike-friendly infrastructure? Or perhaps a more leisurely city like Portland or Minneapolis, known for their extensive cycling culture? The answer, I suspect, may reveal insights into the broader trends shaping urban planning and transportation policies across the US.
