Bicycles and transit are very compatible. In Santa Clara County, CA, USA, all transit vehicles (trains, light rail, and buses) allow bicycles at all times, and it is recognized that bicycles increase transit use and vice-versa.
Note: For bicycle advocacy organizations see California Bicycle Coalition, League of American Bicyclists or California Association of Bicycle Organizations. There are numerous local groups that they can refer you to.
