Bike Racks on Buses

All Golden Gate Transit buses are equipped with bike racks—front-mounted racks that can accommodate up to 3 bikes or interior underbelly racks that can accommodate up to 2 bikes. 

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.
  • Electric bikes (e-bikes) are only allowed on buses with front-mounted bike racks. E-bike batteries must remain on the bike and cannot be brought on board the bus. E-bikes cannot weigh more than 55 lbs. GGT cannot guarantee that front-mounted bike racks will be available to transport e-bikes. To find out if a bus with a front-mounted bike rack will serve your stop, please contact Customer Service at 415.455.2000. You can also try pantographapp to determine which bus is serving your route and stop. The information on Pantograph is generally reliable but we can't guarantee it. 

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.
  • Gas-powered bikes are NOT accepted on GGT.

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.
