A bicycle bell is a percussive signaling instrument mounted on a bicycle for warning pedestrians and other cyclists. The bell is a required piece of equipment in some jurisdictions. [1] [2] [3] [4] They are usually mounted on the handlebars and thumb activated.
The bicycle bell was invented by John Richard Dedicoat, [5] and patents for bicycle bells appear as early as 1877. [6]
The most common bells are actuated by a thumb-operated lever that is geared to rapidly rotate two loosely slung metal discs inside the bell housing. Said discs repeatedly rattle and strike the bell to produce a sound not unlike that of an electric bell. This type of bell [7] comes in left and right handed versions. Left handed versions are mounted on the left side of the handle bars and are used in countries that drive on the left hand side of the road. The right hand is then free to give traffic signals.
Simpler types also exist, with a spring-mounted external clapper that creates a "ding-ding" sound when the clapper is pulled with a finger and released. Some bells, particularly these "ping" types, work poorly in rainy conditions because water drops clinging to the bell damp the vibrations which produce sound.[ citation needed ]
Bicycle bells have also been used as musical instruments in such notable recordings as "You Still Believe in Me" on Pet Sounds by The Beach Boys [8] and "Bicycle Race" by Queen and more.
A pedestrian crossing is a place designated for pedestrians to cross a road, street or avenue. The term "pedestrian crossing" is also used in the Vienna and Geneva Conventions, both of which pertain to road signs and road traffic.
Traffic lights, traffic signals, or stoplights – also known as robots in South Africa – are signalling devices positioned at road intersections, pedestrian crossings, and other locations in order to control the flow of traffic.
A bicycle brake reduces the speed of a bicycle or prevents it from moving. The three main types are: rim brakes, disc brakes, and drum brakes.
A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another.
The Automatic Warning System (AWS) provides a train driver with an audible indication of whether the next signal they are approaching is clear or at caution. Depending on the upcoming signal state, the AWS will either produce a 'horn' sound, or a 'bell' sound. If the train driver fails to acknowledge a warning indication, an emergency brake application is initiated by the AWS. However if the driver correctly acknowledges the warning indication by pressing an acknowledgement button, then a visual 'sunflower' is displayed to the driver, as a reminder of the warning.
A train whistle or air whistle is an audible signaling device on a steam locomotive, used to warn that the train is approaching, and to communicate with rail workers. Modern diesel and electric locomotives primarily use a powerful air horn instead of a whistle as an audible warning device. However, the word whistle continues to be used by railroaders in referring to such signaling practices as "whistling off".
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. Electromechanical bells have been widely used at railroad crossings, in telephones, fire and burglar alarms, as school bells, doorbells, and alarms in industrial plants, since the late 1800s, but they are now being widely replaced with electronic sounders. An electric bell consists of one or more electromagnets, made of a coil of insulated wire around an iron bar, which attract an iron strip armature with a clapper.
A bicycle shifter or gear control or gear levers is a component used to control the gearing mechanisms and select the desired gear ratio. Typically, they operate either a derailleur mechanism or an internal hub gear mechanism. In either case, the control is operated by moving a cable that connects the shifter to the gear mechanism.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, which types of cycling environment or cycling infrastructure is safest for cyclists. The merits of obeying the traffic laws and using bicycle lighting at night are less controversial. Wearing a bicycle helmet may reduce the chance of head injury in the event of a crash.
A soap dispenser is a device that, when manipulated or triggered appropriately, dispenses soap. It can be manually operated using a handle or can be automatic. Soap dispensers are often found in public toilets.
The Big RuckusPS250 is a 250cc, CVT transmission-equipped two-seater scooter, manufactured by Honda; marketed in Japan for model years 2004-2007 and in North America for model years 2005-2006 — and noted for its minimal bodywork and expressed light-weight steel tubular frame, akin to the Honda Zoomer.
A train horn is an air horn used as an audible warning device on diesel and electric-powered trains. Its primary purpose is to alert persons and animals to an oncoming train, especially when approaching a level crossing. They are often extremely loud, allowing them to be heard from great distances. They are also used for acknowledging signals given by railroad employees, such as during switching operations. For steam locomotives, the equivalent device is a train whistle.
A bicycle handlebar is the steering control for bicycles. It is the equivalent of a tiller for vehicles and vessels, as it is most often directly mechanically linked to a pivoting front wheel via a stem which in turn attaches it to the fork. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for brake levers, shift levers, cyclocomputers, bells, etc.
In the United States, road signs are, for the most part, standardized by federal regulations, most notably in the Manual on Uniform Traffic Control Devices (MUTCD) and its companion volume the Standard Highway Signs (SHS).
Cycling in Illinois encompasses recreation, bikeways, laws and rules, and advocacy. The director of the Illinois Department of Natural Resources, Joel Brunsvold, explained Illinois cycling opportunities: “Bicycle riding is one of the most popular outdoor recreational activities in Illinois, enjoyed by young and old alike...Illinois has a variety of trails for the public to enjoy. The terrain includes flat prairie land to rolling hills, towering bluffs to the breathtaking river and lakefront views.” Many communities across the state are updating bicycle infrastructure in order to accommodate the increased number of cyclists on the roads.
A vehicle horn is a sound-making device installed on motor vehicles, trains, boats, and other types of vehicles. The horn is activated to warn others of the vehicle's presence or approach, or to call attention to some hazard. Motor vehicles, ships and trains are required by law in some countries to have horns. Trams, trollies, streetcars, and even bicycles are also legally required to have an audible warning device in many areas.
Cycling in Denmark is both a common and popular recreational and utilitarian activity. Bicycling infrastructure is a dominant feature of both city and countryside infrastructure with segregated dedicated bicycle paths and lanes in many places and the network of 11 Danish National Cycle Routes extends more than 12,000 kilometres (7,500 mi) nationwide. Often bicycling and bicycle culture in Denmark is compared to the Netherlands as a bicycle-nation.
The American Star Bicycle was invented in 1880 by G. W. Pressey and manufactured by the H. B. Smith Machine Company in Smithville, Burlington County, New Jersey. It was characterized by a small wheel in front to avoid the problem of tipping forward inherent in other high wheelers. A Star bicycle was photographed being ridden down the steps in front of the United States Capitol in 1885 to demonstrate its longitudinal stability, and Star bicycles were used for the sport of bicycle polo in the mid-1880s. Pressey sued Smith in 1887 for royalties. The name "Star" was attributed to the double star arrangement of the spokes.
A protected intersection or protected junction, also known as a Dutch-style junction, is a type of at-grade road junction in which cyclists and pedestrians are separated from cars. The primary aim of junction protection is to help pedestrians and cyclists be and feel safer at road junctions.
If you get a brand new bicycle from 1 May, make sure its got a brand new bell. Bells on new bikes were compulsory until 1983, but from this weekend they will once again be mandatory.
39:4-11 Audible Signal. A bicycle must be equipped with a bell or other audible device that can be heard at least 100 feet away, but not a siren or whistle.
HTA 75 (5) - Bell: a bike must have a bell or horn in good working order. Set fine: $85.00
Pedestrians have right-of-way on the State's shared path system and the onus is on cyclists to provide a clear warning of their presence, particularly when approaching another path user from behind. For that reason, a person riding a bicycle in WA must have a bell or similar warning device that is in good working order.
