A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
Critical Mass is a form of direct action in which people travel as a group on bicycles at a set location and time. The idea is for people to group together to make it safe for each other to ride bicycles through their streets, based on the old adage: there's safety in numbers.
The penny-farthing, also known as a high wheel, high wheeler or ordinary, is an early type of bicycle. It was popular in the 1870s and 1880s, with its large front wheel providing high speeds, owing to it travelling a large distance for every rotation of the wheel. These bicycles had solid rubber tires and as a consequence the only shock absorption was in the saddle.
Marshall Walter "Major" Taylor was an American professional cyclist. Even by modern cycling standards, Taylor could be considered the greatest American sprinter of all time.
Hybrid bicycles blend characteristics from more specialized road bikes, touring bikes and mountain bikes. The resulting "hybrid" is a general-purpose bike that can tolerate a wide range of riding conditions and applications. Their stability, comfort and ease of use make them popular with novice cyclists, casual riders, commuters, and children.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism such that the pedals always will spin together with the rear wheel. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.

Joe Breeze is an American bicycle framebuilder, designer and advocate from Marin County, California. An early participant in the sport of mountain biking, Breeze, along with other pioneers including Gary Fisher, Charlie Kelly, and Tom Ritchey, is known for his central role in developing the mountain bike. Breeze is credited with designing and building the first all-new mountain bikes, which riders colloquially called Breezers. He built the prototype, known as Breezer #1, in 1977 and completed nine more Series I Breezers by early 1978. Breezer #1 is now in the collection of the Smithsonian Institution’s National Museum of American History.
Arthur Preston Aylesworth was an American stage and film actor.
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, low speeds/distances, and are included in the non-racing/non-touring class and heavyweight or middleweight styles of the road bicycle type.
Lottie Williams was an American character actress whose career spanned both the silent and sound film eras.
The Bicycle Coalition of Greater Philadelphia (BCGP) is a nonprofit advocacy group that has been working to improve conditions for bicyclists in the Greater Philadelphia region through advocacy and education since its founding in 1972.
Maxine Doyle was an American film actress who appeared in almost 40 films between 1933 and 1946. Today's audiences may know Maxine Doyle from her appearance in the Leon Errol musical short Service with a Smile (1934), one of the first films in full Technicolor, which was restored and revived by Warner Bros.
The following outline is provided as an overview of and topical guide to bicycles:
Detroit is a popular city for cycling. It is flat with an extensive road network with a number of recreational and competitive opportunities and is, according to cycling advocate David Byrne, one of the top eight biking cities in the world. The city has invested in greenways and bike lanes and other bicycle-friendly infrastructure. Bike rental is available from the riverfront and tours of the city's architecture can be booked.
Cycling in San Francisco has grown in popularity in recent years, aided by improving cycling infrastructure and community support. San Francisco's compact urban form and mild climate enable cyclists to reach work, shopping, and recreational destinations quickly and comfortably. Though San Francisco's famed steep hills can make cycling difficult, many parts of the city are relatively flat, including some of the most densely populated. However, heavy automobile traffic, the lack of bike lanes on many streets, and difficulty in crossing major streets deter most residents from cycling frequently in San Francisco.
The predecessor of USACycling, the Amateur Bicycle League of America (ABLA) was founded in 1921 and held National Championships starting that year. From 1921 to 1964, these championships were two-, three-, or four-event omniums of track-style events, rather than a road race. USACycling souvenir programs list no results for events in 1931-1934, 1938, and 1942-1944. The 1939 program summarizes the 1937 National Champions. The 1938 results are from a national championship with similar events and format that the Amateur Athletic Union promoted.
The Idaho stop is the common name for laws that allow bicyclists to treat a stop sign as a yield sign, and a red light as a stop sign. It first became law in Idaho in 1982, but was not adopted elsewhere until Delaware adopted a limited stop-as-yield law, the "Delaware Yield", in 2017. Arkansas was the second US state to legalize both stop-as-yield and red-light-as-stop in April 2019. Studies in Delaware and Idaho have shown significant decreases in crashes at stop-controlled intersections. In France and Belgium, some intersections use red-light-as-yield signs.
