At least twice as many men cycle compared to women in the US. In contrast, 55 percent of cyclists in the Netherlands are women, 49 percent in Germany. Infrastructure plays a key role….
… A survey conducted by the Association of Pedestrian and Bicycling Professionals in the spring of 2010 found that women often shy away from cycling because of safety concerns, such as distracted drivers and a lack of cycling infrastructure. The Women’s Cycling Survey report, published in September of this year, notes that “women from large cities were most receptive to the addition of bike lanes as a means to start/ increase their cycling.” In other words, the better the infrastructure, the more likely it is that women in urban environments will bike.
