Steven Vance, editor of StreetsBlog Chicago and frequent contributor to AN, dug through Walk Score’s breakdown of the most bikeable neighborhoods in Chicago.

The rankings are based on several factors, including the prevalence of bike lanes, connectivity, commuting mode share and hills. It also considers the number of neighborhood destinations and, as Vance points out, may consider a shared lane marking as a bike lane. That led to the Illinois Medical District’s surprising fourth place ranking, tailing East Ukrainian Village, Ukrainian Village and Wicker Park.
