Xtracycle is the name of a company [1] and the name commonly used for the variety of load-carrying bicycle that results from use of the company's products: the FreeRadical kit. [2] Web forums and blogs often use the shorthand Xtrabike, Xtra, or simply X to refer to either the FreeRadical extension or the entire extended bicycle.
The FreeRadical was conceived by Ross Evans at Stanford University and developed during his work in the mid-1990s managing a "Bikes Not Bombs" project in Nicaragua, where having a bicycle enhances a person's employment opportunities. In 1998 Evans and his friend Kipchoge Spencer created Xtracycle Inc to manufacture and market the invention, as well as a nonprofit organization, Worldbike, devoted to encourage a bicycle-centric lifestyle and culture. [3]
Despite the fact that the FreeRadical qualifies as an aftermarket bike accessory, its growing acceptance has sparked an Xtracycle aftermarket not formally connected with Xtracycle Inc: varieties of specialized kickstands, electric-assist motors, and even bike-mounted blenders have come to market, even though each requires the prior purchase of a FreeRadical or other Xtracycle-compatible frame to function properly.
Xtracycle Inc has worked with various bicycle manufacturers to build purpose-built extended bicycles compatible with their accessories. The first to actually produce and market an integrated Xtracycle frameset was Surly Bikes with the Big Dummy. [4] XInc continues to form similar covenants with manufacturers in all price ranges, with the goal of making the Xtracycle less of a niche product and more mainstream. XInc is also working on FreeRadical attachments sized for children's and youths' bicycles.
Other applications for the FreeRadical have included linking two Xtracycles to support a mobile stage for use in parades and street fairs, and a computerized chalkpowder-printer device mounted on an Xtracycle that leaves a dot-matrix trail of messages on the street. [5]
In 2008, Xtracycle put their longtail bike frame specifications online [6] as part of their project to open source their longtail frame design. They’ve created a Longtail Standard and logoing to allow vendors to design their products to fit in the Xtracycle FreeRadical ecosystem. The "Longtail Technology" logo can be used on bikes, accessories or packaging. The open sourcing of the patented technology was meant to stimulate the cargo bike movement, while developing a standard for "longtail" frames and accessories. Several frame and accessory makers have adopted the standards, while others have developed competing and incompatible long-frame cargo bike designs. However, the documents are no longer freely available, and now require an agreement with Xtracycle first. [7]
The FreeRadical is an extender for a bicycle.
In 2009 the Radish was launched by Xtracycle. It is a production long-tail bicycle with a low-standover height frame and matching FreeRadical.
In 2013 the EdgeRunner is a second generation cargo bicycle with a 20-inch rear wheel. The EdgeRunner has been called the "Best longtail ever. No contest." [8]
In 2013 the CargoJoe is a folding cargo bike developed in a partnership between Xtracycle and Tern.
In 2011 Xtracycle created a sidecar for cargo transport that can carry up to 250 pounds. [9]
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 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 bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels.
The Cannondale Bicycle Corporation is an American division of Dutch conglomerate Pon Holdings that supplies bicycles. Its headquarters are in Wilton, Connecticut, with engineering offices in Freiburg, Germany. Frames are manufactured in Taiwan.

Trek Bicycle Corporation is a bicycle and cycling product manufacturer and distributor under brand names Trek, Electra Bicycle Company, Bontrager, and Diamant Bikes.

With its headquarters in Waterloo, Wisconsin, Trek bicycles are marketed through 1,700 independently owned bicycle shops across North America, subsidiaries in Europe, Asia, South Africa, as well as distributors in 90 countries worldwide. Nearly all Trek bicycles are manufactured outside the United States, in countries including the Netherlands, Germany, Taiwan, and China.
There have been many human powered vehicles designed and constructed specifically for transporting loads since their earliest appearance in the 20th century. They are referred to variously depending on the number of wheels — typically two, three, or four — and by their specific use. Adjectives used to describe the tasks to which the bicycles, dicycles, tricycles, or quadracycles are put include cargo cycles, freight cycles, box cycles, carrier cycles, and so on. Sometimes they are also called cycletrucks, which uses a sense of the word 'truck' predating the automobile.
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.
The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle to which the crankset attaches, and the bearings that allow the spindle and crankset to rotate. The chainrings and pedals attach to the cranks. Bottom bracket bearings fit inside the bottom bracket shell, which connects the seat tube, down tube and chain stays as part of the bicycle frame.
29ers or two-niners are mountain bikes and hybrid bikes that are built to use 700c or 622 mm ISO wheels, commonly called 29″ wheels. Most mountain bikes once used ISO 559 mm wheels, commonly called 26″ wheels. The ISO 622 mm wheel is typically also used for road-racing, trekking, cyclo-cross, touring and hybrid bicycles. In some countries, mainly in Continental Europe, ISO 622 mm wheels are commonly called 28″ wheels or "28 Incher".
Kogswell Cycles, Inc. was a small bicycle frame company with its headquarters in El Dorado Hills, California. Kogswell frames were designed in the United States and manufactured in Taiwan. Kogswell frames often ran counter to mainstream bicycle industry trends. According to Biking.com, Kogswell "focuses on creating bicycle frames that lean more towards utilitarian design rather than speed and rough roading."

Surly Bikes, or Surly, is a bicycle brand based in Bloomington, Minnesota, United States, that was founded in 1998. It is a division of Quality Bicycle Products, a manufacturer and distributor of bicycles and bicycle parts. Despite sharing a similar name and being headquartered in the U.S. state of Minnesota, Surly Bikes and Surly Brewing Company are separate enterprises, with an agreement between the two companies allowing the bicycle company to display the single word "Surly" on its products. Surly Brewing’s Omar Ansari reached out to Surly Bikes before launching the brewery to make sure there would be no conflict.

A fatbike is an off-road bicycle built to accommodate oversized tyres, typically 3.8 in (97 mm) or larger and rims 2.16 in (55 mm) or wider, designed for low ground pressure to allow riding on soft, unstable terrain, such as snow, sand, bogs and mud. Fatbikes are built around frames with wide forks and stays to accommodate the space required to fit these wide rims and tires. The wide tires can be used with inflation pressures as low as 34 kPa; 0.34 bar (5 psi) to allow for a smooth ride over rough obstacles. A rating of 55–69 kPa; 0.55–0.69 bar (8–10 psi) is suitable for most riders. Fatbikes were developed for use in snow or sand, but are capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails.
