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:

  • 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.
  • Bikes are NOT allowed inside buses that have bike racks, even if the rack is full. One exception to this rule is on Route 40/40X. Cyclists commuting across the Richmond-San Rafael Bridge may store a maximum of two bicycles inside the bus (in the wheelchair securement area) only when the exterior rack is full. Wheelchair users have priority over cyclists at all times. Load your bike through the rear door, lift the flip-up seat to the up position, and use your own straps to secure the bike without blocking the aisle.
  • 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.
