It was a difficult time to be a cyclist in the city and feel safe while on the road everyday in 2012.

By December, Boston had mourned five people killed in bike-related accidents that involved cars and other vehicles.

The fatal crashes were enough to get officials from departments and organizations all over Boston to come together and discuss ways to ensure rider safety for those traveling on two wheels.

In 2013, leaders have promised to continue to ramp up safety efforts to improve city streets and make Boston a top city for cyclists.

For starters, they have brought back famed “Bike Czar” Nicole Freedman, who officials say was partly responsible for transforming the Hub from one of the worst cycling cities in the country to a nationally-recognized biking location.

“In 2007, we set out to make Boston a world-class bicycling city, and Nicole was the clear choice for a leader who both shared that vision and had the passion to make it a reality,” Mayor Tom Menino said. “Since her departure, Boston Bikes has continued to thrive and improve access for all cyclists, and we’re thrilled Nicole has joined us again to keep that momentum going.”

Freedman, a former Olympic cyclist, held the title as director of the Boston Bike program from 2007, until she left in April 2012.

Now, upon her return, she will resume that roll.

“I’m so excited to be back in Boston, and grateful for the vision of the Mayor, and the work of Kris Carter and the team of people who have continued to lead Boston Bikes on a successful path,” said Freedman.

During her previous tenure, Freedman oversaw the launch of the New Balance Hubway bike share system, worked to install 50 miles of new bike lane and 850 new bicycle racks, and helped bring the first professional bicycle race to Boston in nearly 20 years.

“Over the past five years, the program has made tremendous strides, but there’s always more work to do. We’re looking forward to another successful year of cycling in Boston,” she said.

With Freedman back, hopefully she will team up with the residents in and around Boston that have been championing bike safety efforts by building better two-wheeled modes of transportation.
