Muni welcomes and encourages bicycle riders to use the exterior bike racks provided on our bus routes. All Muni buses in regular service have front-loading bike racks able to hold two bikes each. Historic streetcars, cable cars, and Muni Metro light rail vehicles do not have bike racks; full-size bicycles are not permitted on those vehicles.
Placing your bike on a rack takes three steps and less than 20 seconds. It is the responsibility of the cyclist to read and comply with the safety rules and instructions listed below for the safe and responsible use of Muni bike racks.
Bikes in Buses
Only folding bicycles are allowed inside all Muni vehicles (with the exception of cable cars).
- must be folded and kept with their owner.
- cannot be placed on or block seats.
- cannot not interfere with customer movement.
- cannot block wheelchair access and movement.
Bike Rack Rules
Customers may use Muni bike racks at their own risk.
- Muni assumes no responsibility for bikes that are stolen, damaged, lost, or left on racks.
- The cyclist assumes full responsibility for loading and unloading his or her bike. Operators will not provide assistance.
- Bike racks are available during all hours of operation, on a first come, first served basis, with a limit of two bikes per rack. No service charge or permit is needed.
- Before loading a bike, a cyclist must make eye contact with the bus operator, in order to make sure that the cyclist is seen and all safety precautions are taken.
- All exterior items that are loose or may impede rack use, such as air pumps, saddlebags, luggage, front mounted horizontal racks or baskets, must be removed from the bicycle. Rear-mounted racks, baskets, and child seats are permitted.
- Bike racks cannot accommodate handlebars that exceed 42 inches, tires wider than 3 inches, tricycles, or motorized bikes.
- All two-wheeled bikes, single rider bikes (road bikes, mountain bikes, pre-teen, and junior bikes) must have a wheel size of 20 inches or larger, no exceptions.
- Non-folding bikes are not allowed inside any Muni bus, streetcar, or other transit vehicle at any time. However, as of May 24, 2011, folding bicycles are allowed inside all Muni vehicles except cable cars.
- Please remember that all seats marked for seniors or persons with disabilities must be surrendered when needed.
- Customers may not lock a bike to the Muni bike rack.
