Silicon Valley Bicycle Coalition
This organization encourages bicycle and motorist awareness and teachs bicyclists safe traffic riding skills. They advocate for more bicycle friendly roads and connecting the trails across the region. They also take old bicycles and rebuild them to make them safe enough to give to those who cannot afford them. There are many volunteer opportunites in Santa Clara and San Mateo counties such as helping to rebuild old bikes, providing information about biking routes, reporters and photographers to contribute to their newsletter, support outreach programs and others.
Depends on which position you volunteer. Please call for more information.
