Pedal and Park

The Massachusetts Bay Transportation Authority operates subway, bus, commuter rail, and ferry service in the Greater Boston region. Boston has some of the highest rates of non-motorized commuting in the United States, including high bicycle usage. The MBTA offers certain provisions for riders wishing to make part of their trips by bicycle. The agency allows bicycles to be carried on all fixed-route services except the Green Line and the Ashmont-Mattapan High Speed Line light rail lines, although they are restricted on the commuter rail and heavy rail subway services at peak hours. Bicycle storage areas are offered at many stations, with "Pedal and Park" locking bicycle cages at certain high-usage stations.

Standard non-folding bicycles are permitted on most MBTA service, though they may be restricted at peak hours:

Folding bicycles are allowed on all MBTA vehicles at all times provided they are fully folded before going through faregates or entering vehicles.

Bicycles are not allowed to be transported through the transfer stations at Park Street, Downtown Crossing, and Government Center at any times due to crowding in narrow corridors in the old stations. Motorized vehicles and bicycle trailers are not permitted. The MBTA states that "[b]icycles may also be prohibited during holidays..., special events, service disruptions, and other periods when crowding or special conditions exist."

Most (over 95%) MBTA stations have bicycle racks available. A number of commuter rail and subway stations, as well as the bus stations at Arlington Heights and Watertown Square, have covered bicycle parking areas. A small number, including South Acton, have individual bicycle lockers.

A small number of MBTA stations have "Pedal and Park" cages, which allow for more secure bicycle storage than normal open racks. Each cage includes racks for 50 to 150 bicycles, six security cameras, lighting, and a police intercom system, with the intent of deterring bicycle thefts. As of July 2015^[update], there are sixteen cages at fourteen stations:
