Transportation Alternatives is a non-profit organization in New York City which works to change New York City's transportation priorities to encourage and increase non-polluting, quiet, city-friendly travel and decrease automobile use. TransAlt seeks a transportation system based on a "Green Transportation Hierarchy" giving preference to modes of travel based on their relative benefits and costs to society. To achieve these goals, T.A. works in five areas: Cycling, Walking and Traffic Calming, Car-Free Parks, Safe Streets and Sustainable Transportation. Promotional activities include large group bicycle rides.

Cycling in New York City is associated with mixed cycling conditions that include dense urban proximities, relatively flat terrain, congested roadways with stop-and-go traffic, and streets with heavy pedestrian activity. The city's large cycling population includes utility cyclists, such as delivery and messenger services; cycling clubs for recreational cyclists; and increasingly commuters. Cycling is increasingly popular in New York City; in 2018 there were approximately 510,000 daily bike trips, compared with 170,000 daily bike trips in 2005.
