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.
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 legs, and comfort, because the large wheel provided greater shock absorption.
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.
Trek Bicycle Corporation is a bicycle and cycling product manufacturer and distributor under brand names Trek, Electra Bicycle Company, Bontrager, and Diamant Bikes. The company has previously manufactured bikes under the Gary Fisher, LeMond Racing Cycles, Klein, and Villiger Bikes brand names. 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.
Motorenwerke Zschopau GmbH is a German motorcycle manufacturer located in Zschopau, Saxony. The acronym MZ since 1956 stands for Motorenwerke Zschopau GmbH. From 1992 to 1999 the company was called MuZ, an acronym for Motorrad und Zweiradwerk.
KTM AG is an Austrian motorcycle, bicycle and sports car manufacturer owned by Pierer Mobility AG and the Indian manufacturer Bajaj Auto. It was formed in 1992 but traces its foundation to as early as 1934. Today, KTM AG is the parent company of the KTM Group, consisting of a number of motorcycle brands.
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.
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.
ZF Sachs AG, also known as Fichtel & Sachs, was founded in Schweinfurt in 1895 and was a well-known German family business. At its last point as an independent company, the company name was Fichtel & Sachs AG.
Reichshof is a North Rhine-Westphalian municipality in the Oberbergischer Kreis in Germany, about 40 km east of Cologne. It is a health resort, known for its good climate. The municipality consists of 106 villages and hamlets. The most important villages are Denklingen, Eckenhagen (1900), Brüchermühle (1700) and Wildbergerhütte (1600).
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".
ISO 5775 is an international standard for labeling the size of bicycle tires and rims. The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO). It is designed to make tire sizing consistent and clear. It replaces overlapping informal systems that ambiguously distinguished between sizes. For example, at least 6 different "26 inch" sizes exist, and "27 inch" wheels have a larger diameter than American "28 inch" wheels. The Japanese Industrial Standards Committee also cooperates with ISO 5775. The corresponding Japanese standards are JIS D 9112 for tires and JIS D 9421 for rims.
SR Suntour is a Taiwanese manufacturer of bicycle components, formed in 1988 when Osaka based SunTour (Maeda) went bankrupt and was purchased by Sakae Ringyo Company, a major Japanese maker of aluminum parts, particularly cranks and seat posts. SunTour's sales and commercial success peaked from the late 1970s to the mid-1980s.
Miyata is a Japanese manufacturer of bicycles, unicycles and fire extinguishers. The company has been in operation since 1890. Miyata was also one of the first producers of motorcycles in Japan under the name Asahi. The Asahi AA was the first mass-produced motorcycle in Japan.
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically the second largest source, after wind resistance, of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle.
A wheelie bike, also called a dragster, muscle bike, high-riser, spyder bike or banana bike, is a type of stylized children's bicycle designed in the 1960s to resemble a chopper motorcycle and characterized by ape hanger handlebars, a banana seat with sissy bar, and small wheels. Notable examples include the Schwinn Sting-Ray and Krate lines and the Raleigh Chopper line. Other notable manufacturers and retailers that offered models include AMF, CCM, Columbia, Huffy, Iverson, J. C. Penney, Malvern Star, Monark, Murray, Ross, Sears, and Vindec.
27.5 mountain bikes are mountain bikes which use a large volume tire that is approximately 27.5 inches in diameter, 56 mm wide on an ISO 584 mm rim. 27.5 mountain bikes are also called tweeners, since it "fits between" the traditional 26-inch wheels and the newer 29ers".
