Sunday's free event drew the type of traffic Angelenos aren't used to seeing. Bicycles - thousands of them - traveled more than 15 miles from downtown Los Angeles to Venice Beach.
Since it began in 2010, CicLAvia has quickly become Los Angeles County's most popular public event. An estimated 100,000 participants took part in the fun this time. Some were on scooters, others low rider bicycles and tricycles. Many walked the route.
Still some participants couldn't help but think about of the Boston Marathon bombing.
"Our prayers and thoughts are with the people in Boston, so I thought this would be a monumental event today to kind of show our support," said cyclist Michael Kadmiri.
Extra law enforcement and bomb-sniffing dogs made certain the bike path was safe.
"I had second thoughts about coming today because of the incident in Boston, but it's my first time and I thought, you know what? I can't let something like that keep me from having fun," said cyclist Sandra Cevellos.
The event kicked off with a short statement from Los Angeles Mayor Antonio Villaraigosa.
"We've got to start sharing the road," he said. "The road isn't just for cars. It's for bikes, it's for pedestrians, it's for everybody."
No registration was needed and there was no true starting point either.
The next CicLAvia will be held June 23.
