In the Seattle suburb where I grew up, the main transportation choice most residents face is what kind of car to buy. I moved to the city after college and, inspired by the “car-lite” lifestyles of several friends, decided to give cycling a try.

I fell in love with it. Urban cycling freed me from slow buses, parking meters, and mind-numbing elliptical machines. I arrived at work with more energy. I lost weight. I discovered charming neighborhood restaurants. I could smell fresh laundry and dinners in the oven while I pedaled home through residential streets. Getting from A to B on my bike became the best part of my day.

Recently, I won a fellowship and got to spend six months living life on two wheels in the world’s most bike-friendly cities. I brought home 10 lessons for us here in the States:

1. It’s the infrastructure, stupid!

Amazing infrastructure makes cycling normal and safe in bike meccas. For example, parked cars to the left of the bike lane not only provide a barrier between motorized traffic and cyclists, they also minimize a cyclist’s chance of getting “doored.” Most cars only have one occupant, the driver, and drivers get out on the left.

Bikes move at different speeds than cars or pedestrians, so intersections are safer for cyclists if they have their own traffic signal rhythm. Cyclists in Copenhagen generally get a slight head start over cars so that they’ll be more visible as they cross the intersection.

2. Bike share!

Bike-share programs are sweeping the world, and they are very successful at boosting bike numbers. About 130,000 trips are made each day in Paris on public bikes thanks to the pioneering Vélib bike-share program.

In Barcelona, people used to point and stare if you were pedaling a bike, but in just a few years, a bike-share program called Bicing has changed that. Bicing started in 2007 and quickly tripled cycling trips in the city, according to Miquel Ruscalleda, who directs Barcelona’s cycling efforts. Currently 46 percent of the people you see on bikes in Barcelona are on bright red Bicing bikes.

Ruscalleda also reports that the “safety in numbers” phenomenon is working in his city. Cyclists had a .008 percent chance of being in a traffic accident in 2005, and the rate has dropped to around .005 percent presently.

3. It’s safer than a sofa.

Sedentary living doubles the risk of cardiovascular diseases, diabetes, and obesity. Combating diseases of sedentary living requires 30 minutes of moderate exercise every day — a minimum many people around the world are unable to meet. But almost 40 percent of Copenhagen residents meet their minimum exercise requirements by cycling to work or school.

Copenhagen’s Public Health Department calculates that even when accident costs are factored in, every mile of cycling translates to net health benefits worth $1.30. A recent public health campaign in Copenhagen reminded residents, “You’re safer on your bike than on the sofa!”

4. Say “thank you.”

Cyclists also save city governments money by reducing traffic congestion, stormwater run-off, air pollution, and road maintenance expenditures. Many cities are doing little things to show their gratitude.

Barcelona recently installed a counter on a main route displaying the time, temperature, bike count for the day, and progress toward the official annual ridership goal for that route.

Copenhagen has begun putting in footrests at intersections. They say, “Hi, cyclist! Rest your foot here … and thank you for cycling in the city!”

5. Turn streets into backyards.

Dutch road engineer Hans Monderman hated traffic signs in cities and towns. His reasoning was simple: Most drivers don’t look at signs. Speed bumps and stop signs also don’t do much because drivers are notorious for accelerating to “make up time” after each interruption.

Monderman redesigned Dutch towns so that drivers felt like they were passing through someone’s backyard. Monderman’s “backyard” plans called for street furniture — benches, picnic tables, sand boxes, pea patches, trees, flowerpots, and ping pong tables. Drivers either saw or sensed the presence of people and children, and basic social laws kicked in: It isn’t polite to speed through someone’s backyard.

Many residential streets throughout Europe now embody Monderman’s principles.

6. Let prices tell the truth.

Driving — and parking — is much more expensive in other parts of the world. Filling up a tank of gas in Japan will cost you about $7.25 per gallon, and gas prices in most European countries are also much higher than in the U.S.

Donald Shoup, an economist and the author of The High Cost of Free Parking says, “People who want to store their car shouldn’t store it on the most valuable land on the planet, for free.” Street parking is typically $4.50 per hour in European cities.

7. You don’t need “bike clothes.”

Most of the women and men I saw on bicycles throughout Europe and Japan didn’t wear special clothes. People just wore their usual outfits, heels and all.

Women from London to Tokyo looked beautiful, stylish, and feminine while they were cycling. Men frequently pedaled in suits. “Style over speed,” says Mikael Colville-Anderson, who started the Cycle Chic movement.

8. Electrify it.

A cargo bike with two kids and groceries can be hard to get up hills. That’s why many parents in hilly Zurich, Switzerland, use electric-assist bikes. They can also help people who are battling obesity or recovering from a heart attack. A bike shop owner I interviewed in Zurich makes custom electric-assist bicycles for disabled customers who would otherwise be dependent on public transportation.

9. Admit it: It’s emotional.

Smell and touch are the senses most linked to our emotions. In Europe and Japan, I spoke with dozens of urban cyclists who talked about the curious happiness derived from activating your senses and connecting with your city on a bicycle. One Amsterdam father’s voice actually cracked with emotion as he reflected on his morning and afternoon rides with his son. His toddler sat in a front-mounted childseat. The father talked about how nice it was to smell his son’s head during the commute to day care.

10. It’s a virtuous cycle.

“Cycling isn’t just a part of the Dutch DNA,” Marc van Woudenberg told me in Amsterdam, where 47 percent of residents make at least one trip per day on a bicycle.

The Dutch have the highest rates of utility cycling in the world because citizens have made it clear to politicians that cycling infrastructure is a priority. Better infrastructure recruits more people onto bikes, which creates more advocates for better infrastructure, which recruits more people onto bikes, and so on. Today, the Dutch continue to advocate for infrastructure that will facilitate cycling.

After six months on my bicycling wanderjahr, I’m inspired by all the creative ways cities are transforming themselves to meet the needs of the 21st century: low on carbon, high on physical activity, low on noise and danger, high on fun and style. Here in the U.S., we have exciting opportunities to join the world’s great bike cities and redefine urban transportation on two wheels.
