The sociable or buddy bike [1] or side by side bicycle is a bicycle that supports two riders who sit next to one another, in contrast to a tandem bicycle, where the riders sit fore and aft. The name "sociable" alludes to the relative ease with which the two cyclists can speak with each other, unlike on the tandem.
Bicycling through Time by Paul and Charlie Farren has a picture of a sociable with a frame under each rider and two wheels between them from 1897. The Ford Museum in Detroit has a similar sociable on display. More modern single framed sociables may have started with Australian cyclist Hubert Opperman, [2] although in its basic form the design has been around for longer, since the end of the 19th century. It was originally marketed by the Punnett Cycle Company. Historically it has been used as a courting bike; gentlemen would be able to spend time with ladies in an activity that allowed proximity. [3]
For several years the Taiwanese "Buddy Bike" sociable was available on Ebay. There are currently[ when? ] no commercially available sociable two-wheelers, although there are plans in circulation by which a person with welding and metal fabrication skills could make one. There are some sociable three- and four-wheeled machines (quadracycles) on the market, however.
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.
A tandem bicycle or twin is a form of bicycle designed to be ridden by more than one person. The term tandem refers to the seating arrangement, not the number of riders. Patents related to tandem bicycles date from the mid 1880s. Tandems can reach higher speeds than the same riders on single bicycles, and tandem bicycle racing exists. As with bicycles for single riders, there are many variations that have been developed over the years.
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography, application and a frame with a suspension mechanism for the rear wheel. Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height.
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Some recumbent riders may choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by back and buttocks. On a traditional upright bicycle, the body weight rests entirely on a small portion of the sitting bones, the feet, and the hands.
A bicycle brake reduces the speed of a bicycle or prevents the wheels from moving. The two main types are: rim brakes and disc brakes. Drum brakes are less common on bicycles.
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.
Pashley Cycles is a British bicycle, tricycle and workbike manufacturer based in Stratford-upon-Avon in Warwickshire, England. The company was started in 1926 and still manufactures bikes in the UK.
The crankset or chainset is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called chainrings or chainwheels attached to the cranks, arms, or crankarms to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain.
A touring bicycle is a bicycle designed or modified to handle bicycle touring. To make the bikes sufficiently robust, comfortable and capable of carrying heavy loads, special features may include a long wheelbase, frame materials that favor flexibility over rigidity, heavy duty wheels, and multiple mounting points.
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.
Sir Hubert Ferdinand Opperman, OBE, referred to as Oppy by Australian and French crowds, was an Australian cyclist and politician, whose endurance cycling feats in the 1920s and 1930s earned him international acclaim.
This is a glossary of terms and jargon used in cycling, mountain biking, and cycle sport.
A bicycle trailer is a motorless wheeled frame with a hitch system for transporting cargo by bicycle. It can greatly increase a bike's cargo capacity, allowing point-to-point haulage of objects up to 3 cubic metres in volume that weigh as much as 500 kg. However, very heavily loaded trailers may pose a danger to the cyclist and others, and the voluntary European standard EN 15918 therefore suggests a maximum load of 60 kg on trailers without brakes.
A trailer bike is a one-wheeled, or sometimes two-wheeled, bicycle trailer designed to carry one or more children in positions that closely resemble that of a bicycle rider. It can be described as the, "back half of a bicycle." The rider of a trailer bike usually has a saddle, handlebars, and pedals. Some fold for more compact storage.
Malvern Star is a manufacturer of bicycles based in Melbourne, Australia. The company was established in 1902, and went on to become a known brand in Australia.
A quadracycle is a four-wheeled human-powered land vehicle. It is also referred to as a quadricycle, quadcycle, pedal car or four-wheeled bicycle amongst other terms.
The following outline is provided as an overview of and topical guide to bicycles:
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios.
All the disadvantages of a tandem and none of the advantages!
In Australia an odd "two-seater" bicycle has been invented by Hubert Opperman, famous distance cyclist.
