Bike Score Is Here

Bike Score Map of Seattle

Just in time for Bike to Work Week, we are thrilled to launch Bike Score and our first ranking of the most bikeable U.S. cities.

See how your city ranks and vote for your city to be next to get Bike Score.

We’ll add Bike Score for the top 10 cities receiving votes between now and the end of National Bike Month on May 31, 2012.

How Bike Score Works

Bike Score provides a 0-100 rating of the bikeability of a location based on the availability of bike infrastructure (lanes and trails), the hilliness of the area, destinations and road connectivity, and the number of bike commuters.

The Bike Score for a city is then calculated by applying the Bike Score algorithm block-by-block throughout the city and weighting the scores by population density. Read the methodology details.

We collected thousands of votes for over one hundred ideas from our community on how to calculate Bike Score. Thank you!

The Bike Score methodology was developed in collaboration with Professor Meghan Winters at Simon Fraser University and Professors Michael Brauer and Kay Teschke at the University of British Columbia under a grant from the Canadian Institutes of Health Research.

Bicycling by the Numbers

• Americans made 4 billion trips by bicycle in 2009, more than twice as many as in 2001.
• Bike commuting increased 43% between 2000 and 2010.
• 71% of Americans say they would like to bicycle more than they do now.

Bike Score: Built by bikers, for bikers!


  1. Cliff

    Nice job! Awesome new tool.

  2. You’ve got the maps – is the Street Smart calculation too intensive to permit address-level searches? Yet another city ranking is fine, but to me the magic of Walk Score is the location data. Is this on the way?

  3. Josh Herst

    It’s on the roadmap!

  4. The findings generally jibe with what I’ve observed on the ground in numerous cities, although the methodology does tend to mark parks (particularly hilly ones!) and CBDs as unnecessarily bike-unfriendly.

    On another note, may I ask that your future maps not use red and green as opposing colors? Those are particularly difficult hues for us colorblind people (~4% of the population) to discern. You can find colorblind-friendly map palettes at the ColorBrewer website.

    Bike score needs to consider annual weather conditions. I’d rather bike in a hilly city than a city with frequent rain or regular snow or extreme heat.

  6. Josh Herst

    Weather affects biking less than you may think:

  7. How do we vote for an area to be scored without Twitter?

  8. Josh Herst

    No Twitter? Vote here (add a comment) to get Bike Score in your city!

  9. Larry

    Charlotte, NC

  10. Lee Kessler

    Given the high rankings for Boulder & Minneapolis, it is evident that no one considered weather in the equation. For obvious reasons, I don’t really enjoy bike commuting when I am knee-deep in snow.

    Cities with little or no snowfall – even northern cities like Portland, Oregon & Seattle should rank higher simply becuase you can cycle commute nearly every day.

    I live 30 miles north of Seattle, and I bike commuted just under 200 days last year – and I walked all of the remainder less six (?) when I had appointments that required a car to attend during my work day.

  11. Kevin Bolling

    New York,NY is in the top ten and Austin, Texas is not! Great year round weather, lot’s of bike lanes, a vibrant bicycling community and support from local business’s/local government for Bike To Work Programs prove that Austin is one of the most aware biking centers in the country.

  12. Ramon

    Irvine, California

  13. Denny

    Naples FL is the top biking city in the USA! Hundreds of Miles of paved paths, generally friendly traffic/drivers, fabulous weather, and few hills all make Naples great for biking!

  14. Shelley

    Requesting Albuquerque, NM. We have over 500 miles of bike paths and trails. We were voted the best bike city in 2005 and 2006. We have great weather too.

  15. Michael

    You should add Fairhope, AL. They have just widened all of their bike lanes and are part of the Eastern Shore Bikeway that runs for miles down the east side of the Mobile Bay.

  16. Matt

    Requesting Irvine, California! We have lot’s of Class I and Class II bike lanes.

  17. Steve

    Philly, perfect scale for biking with great trails!

  18. Nicole

    Requesting Reston, Va, Sterling, VA….environs of Washington DC. Thanks!

  19. Tim S.

    Bravo/Brava! (just bike)
