The 10 Most Bike-Friendly Cities in America

Editor's Note: This story originally appeared on SmartAsset.com.

Biking is an eco-friendly, cheap, fun and healthy way to commute in the city.

But not all cities are equally accessible for riders — some cities have designated bike lanes, while others simply lack the infrastructure. Nor are all cities the most affordable for the more savings-savvy cyclist.

Keeping this in mind, SmartAsset identified and ranked the most bike-friendly cities in America for 2021.

We compared the 100 largest U.S. cities across seven metrics, including bike score, percentage of bicyclist commuters, bicyclist fatalities, miles of protected bike lanes, income after housing costs, average number of days with precipitation and average number of days with extreme temperatures.

For details on our data sources and how we put all the information together to create our final rankings, check out the data and methodology section at the end.

Here are the best cities for biking in America.

Data and Methodology

SmartAsset analyzed 100 of the largest U.S. cities across the following seven metrics to find the best biking cities in America:

• Bike score. This is a measure of how suitable a city is for biking on a scale of 0 to 100. Data comes from walkscore.com and was pulled in May 2021.
• Percentage of commuters who bike to work. Data comes from the Census Bureau’s 2019 1-year American Community Survey.
• Bicyclist fatalities per 100,000 residents. Data comes from the National Highway Traffic Safety Administration (NHTSA) Motor Vehicle Crash Data Querying and Reporting and is for the five-year period from 2014 through 2018. This figure is measured at the county level.
• Miles of protected bike lanes. Data comes from PeopleForBikes.org
• Income after housing costs. This is the median household income minus median annual housing costs. Data comes from the Census Bureau’s 2019 1-Year American Community Survey.
• Average number of days with precipitation. Data comes from the National Oceanic and Atmospheric Association and represents 20-year averages from 2000-2020.
• Average number of days with extreme temperatures. This is the average number of days in one year with temperatures colder than 30 degrees Fahrenheit and warmer than 80 degrees Fahrenheit. Data comes from the National Oceanic and Atmospheric Association and represents 20-year averages from 2000-2020.

First, we ranked each city in each metric. We then found the average ranking for each city, with all but two metrics receiving an equal weight. Bike score and five-year bicyclist fatalities per 100,000 residents each received a double weight. We then used this average ranking to create our final score. The city with the best average ranking received a score of 100 and the city with the worst average ranking received a score of 0.
