Largely on account of safety concerns, women are riding far less than men according to data from New York’s Citi Bike program. In fact, between July through December 2013, men took 76.3% of all trips, and women 23.7%.
From NYU Rudin Center for Transportation:
Women typically attribute reduced cycling numbers to safety among car traffic, and considering Citi Bike’s distribution across some of the most congested parts of Manhattan and Brooklyn, lower female participation makes sense. Further analysis of the gender divide by bike share station shows that bike stations in Manhattan are predominantly used by men, while Brooklyn stations are more proportionately popular among women. Of the top ten stations for each gender, women preferred the Brooklyn residential neighborhoods of Fort Greene and Clinton Hill, while men were overwhelmingly represented in bustling midtown Manhattan. Women also chose stations in areas with fewer lanes of traffic, more limited truck traffic, fewer collision-based cyclist injuries in recent memory, and in some cases, fast access to bridge entrances; men most often chose stations with more traffic, some truck traffic, some collision-based cyclist injuries, and, typically, connectivity to major transit hubs.
