Bike Racks on Buses

All Golden Gate Transit buses are equipped with bike racks—front-mounted racks that can accommodate up to 3 bikes and underbelly racks that can accommodate up to 2 bikes. Front-mounted racks are on all 40-foot buses and 60-foot articulated buses; underbelly racks are on all 45-foot buses.

Bike Rack Rules

Bike access on Golden Gate Transit buses is a privilege, not a right. It is the cyclist's responsibility to read and comply with the following safety rules:

  • Bikes are NOT allowed inside Golden Gate Transit buses.
  • Customers use bike racks at their own risk. Golden Gate Transit assumes no responsibility for bikes that are lost, stolen, damaged, or left on racks.
  • Racks are available during all hours of operation on a first-come, first-served basis.
  • No additional fees or permits are needed.
  • Cyclists MUST load and unload their bikes themselves. For safety reasons, bus operators may NOT leave the bus to assist cyclists.
  • All loose items, such as accessories, water bottles, air pumps, luggage, flags, bags, etc., MUST be removed before loading.

Bike Rack Limitations

  • ONLY single-rider, two-wheel bikes with a wheel size of 20" or larger—including road bikes, hybrid bikes, mountain bikes, and junior/pre-teen bikes—can fit on the bike racks.
  • Bikes with front fenders or tires wider than 3" will NOT fit on exterior bike racks.
  • Recumbent, tandem, motorized, three-wheeled, muddy, dirty, or greasy bikes are NOT permitted on racks or inside buses.
  • Bike handlebars cannot extend more than 42" from the front of the bus.
  • Bikes with rear-mounted baskets or child seats can fit on the exterior bike racks, but NOT on the under belly racks. Bikes with front-mounted baskets or horizontal racks will NOT fit on either front-mounted or under belly bike racks.

Bike racks are also available at over 40 Golden Gate Transit bus stops, with a capacity of up to 6 bicycles. For bike rack locations, visit our Bike Rack Locations page or see the Golden Gate Transit Guide.
