Officials said 52-year-old Bruce Rosar was killed. Due to an ongoing investigation, officials are releasing few details about the crash.
According to Rosar's biography on his Web site, he had been bicycling in the Triangle area for over two decades.
"If I could have thought of anyone who might have been involved in an accident, he would have been the last person I would have thought of," said David Cole, a member of the NC Bicycle Club.
Rosar was known locally and nationally for his involvement in cycling. He was the director of the North Carolina Active Transportation Alliance and involved in many other bicyclists organizations.
"He was very active in the League of American Bicyclists, he was on their national board, he was one of their certified instructors so he taught classes in bicycle safety," Cole said. "So if there was anybody who played by the rules, it was Bruce."
Following the news of Rosar's death, the League of American Bicyclists Board Chair Amanda Eichstaedt released a statement that said in part, "I am terribly sad to announce the death of Bruce Rosar ... he will be missed terribly and our hearts go out to his family, friends and riding colleagues."
