What is the least bike-friendly city in the US?

Could you please elaborate on what factors contribute to a city being deemed the least bike-friendly in the US? Is it the lack of bike lanes, steep hills, high crime rates, or poor road conditions? How does this city compare to others in terms of promoting cycling as a mode of transportation? Are there any initiatives or policies in place to improve the cycling infrastructure in this city? I'm interested in understanding why this city is considered the least bike-friendly and what can be done to change that.
