A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the diamond frame. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes.

A cruiser bicycle, also known as a beach cruiser or (formerly) motobike, is a bicycle that usually combines balloon tires, an upright seating posture, a single-speed drivetrain, and straightforward steel construction with expressive styling. Cruisers are popular among casual bicyclists and vacationers because they are very stable and easy to ride, but their heavy weight and balloon tires tend to make them rather slow. Another common feature is their ability to be customized with accessories including fenders, lights and saddle bags. They are designed for use primarily on paved roads, moderate speeds/distances, and are included in the non-racing/non-touring class and heavyweight or middleweight styles of the road bicycle type.

LeMond Racing Cycles is a bicycle manufacturer founded by Greg LeMond, an American winner of the Tour de France. LeMond offered a geometry based on the racing frames he used in competition, which had a longer top tube and wheelbase in an otherwise traditional lightweight steel frame. This was to stretch out the rider on the bicycle, with the intent of both lowering the frontal area presented to the wind, and optimizing power and stability. From 1995 until February 2010 Trek licensed LeMond's name for use on a line of its bicycles, believing that the cachet of the name, a diversifying brand portfolio, plus having models offering a longer top tube than Trek's frame geometries helped to expand the bicycle-sales opportunities for the Trek corporation. In September 2013, LeMond partnered with Time Sports to produce a limited run of 300 frames to commemorate his three Tour victories in 1986, 1989, and 1990. In August 2014, Greg LeMond launched the Washoe, a Reynolds 853 steel bike manufactured in the United States.
