In San Francisco, the San Francisco Bike Coalition will have a theme of "Bikes Count," coalition spokeswoman Kristin Smith said.
The theme is a celebration of the Market Street Bike Counter, which is scheduled to be unveiled in the morning, Smith said.
The counter, which has been installed on Market Street between Ninth and Tenth streets, aims to encourage commuters and others to ride bicycles by keeping track of ridership and displaying the number of riders who pass by.
It is the first barometer of its kind in the city's history.
Mayor Ed Lee and a number of San Francisco supervisors are scheduled to be some of the first people to have their bikes roll past the counter, she said.
Smith said the coalition also has several planned community convoy bike rides throughout the city.
Each district supervisor is scheduled to lead a community group to City Hall, where a news conference will be held at about 8:30 a.m. to celebrate the day.
There will also be a commuter convoy with about 500 people that will leave around 6:30 a.m. from the 24th Street BART station and finish at Google in Mountain View, Smith said.
Energizer stations will be set up throughout the city to cheer on bikers as they ride by, Smith said. The stations will have coalition members handing out information about biking, gear, food, coffee and more, she said.
Stations will be scheduled between 7:30 and 9:30 a.m., and 5 and 7 p.m., she said.
Elsewhere in San Francisco, riders who bike to work and commute on the San Francisco Bay Ferry will ride the ferry for free, according to ferry officials.
Meanwhile, in the South Bay, employees at the company Lockheed Martin, a global security, aerospace and information technology company, will celebrate Bike to Work Day by riding from the Santa Clara Convention Center to the Space Systems Company in Sunnyvale, company spokeswoman Dana Carroll said.
Joining them for the ride will be Sunnyvale Mayor Anthony Spitaleri, Carroll said.
In the East Bay, the East Bay Bike Coalition has a number of events scheduled, including riding with Berkeley Mayor Tom Bates and elected officials, coalition officials said.
The city of Berkeley is scheduled to start updating its bicycle plan for the first time in more than a decade. An announcement is planned at a news conference after the bike ride, coalition officials said.
