It’s no secret that Washingtonians love their bikes. Now, thanks in part to the sheer number of cyclists on D.C. streets, the nation’s capital is receiving props as one of the most bikeable cities in the U.S.

According to a new ranking by Bike Score, the District is the nation’s sixth most bikeable large city with 500,000 or more residents. Arlington was named among the most bikeable smaller cities.

Cities were scored based on infrastructure and accessibility (bike lanes and trails) as well as hilliness, road connectivity, and the number of cyclists on city streets.

D.C. received a score of 65 out of 100, which makes it simply “bikeable,” according to Bike Score. To be considered a “biker’s paradise,” cities would need to score between 90 and 100. Even the top-ranked large cities — Portland, Ore., and San Francisco — didn’t earn that title.

But Cambridge, Mass., “crushed it” among smaller cities, Bike Score said in a news release. With a score of 92, Cambridge is the only “biker’s paradise” nationwide.

Bike Score said it released the list this week in honor of National Bike Month and Bike to Work Week. Bike to Work Day is this Friday.
