Bicycle wheel

Countersteering is the name given to the "counter-intuitive" technique used by cyclists to turn corners. Countersteering - A Technical Description. The spinning front wheel of a bicycle or a motorcycle responds to steering inputs exactly like the spinning flywheel of a gyroscope. Both the high-speed and the low-speed steering response are described by the laws of physics, namely the conservation of angular momentum. A detailed description and proof for both speed regimes will be included in this section.

Charles Stewart Mott (b. June 2, 1875 d.1973) was a US industrialist and philanthopist who was born in Newark, New Jersey. His parents were John Coon Mott and Isabella Turmball Stewart. He began a bicycle wheel making business (Weston-Mott Co.), which he moved to Flint, Michigan in 1905 in a merger with Buick. The company was later bought by General Motors in exchange for GM stock. Mott served on the GM Board of Directors until his death in 1973. He was mayor of Flint in 1912, 1913, and i ...

The high bicycle was logical extention of the boneshaker design, the front wheel enlarging (limited by the inside leg measurement of the rider), the rear wheel shrinking and the frame being made lighter. The Frenchman Eugene Meyer is now regarded as the father of the High Bicycle by the ICHC in place of James Starley. Meyer invented the wire-spoke tension wheel in 1869 and produced a beautiful High Bicycle design until the 1880s. James Starley in Coventry added the tangent spokes and the mounting step to his famous bicycle named "Arie ...

The wheelset greatly affects the performance of a racing bike. The wheels rotate at high speeds; consequently their moment of inertia matters a lot. The rim of the wheel can be shaped for greater aerodynamic efficiency making a triangular cross-section to form a teardrop with the tire. For hillclimbs, however, effects from weight overcome those from aerodynamics, and the traditional box-sectioned rim is often used. For aerodynamics and rotating weight, it is generally better to reduce the number of spokes in the wheel. For high-end wheelsets, the spokes can be shaped to have ...

The ICHC no longer distinguishes between a "first true" bicycle with pedals and any precursors. It traces the origins of the bicycle to the two-wheeler principle which requires balancing and is the basis of cycling (and motorcycling). When pedal velocipedes arose there was already a 50-year history of such two-wheeled vehicles. There are several early but unreliable claims for the invention of bicycle-like machines. The Comte de Sivrac is said to have developed a two-wheeler, called a celerifere in 1791, demononstrating it at t ...

Aside from the obvious safety problems, the high-wheeler suffered from front wheel drive (which dirtied the rider's pants) and limited the top speed. Accordingly, inventors tried a rear wheel chain drive. Although a Henry Lawson invented a rear-chain-drive bicycle in 1879, it still had a huge front wheel and a small rear wheel. Detractors called it "The Crocodile," and it failed in the market. John Kemp Starley, James' nephew, produced the first successful safety bicycle, the "Rover," in 1885 (which he never patented). It featured equally si ...

The velocipede had a renaissance in Paris during the late 1860s. A French metalworker attached pedals to the front wheel; at present, the earliest year bicycle historians agree on is 1864. The specific identity of the person who attached cranks is still an open question at International Cycling History Conferences (ICHC). The claims of Ernest Michaux and of Pierre Lallement, and the lesser claims of rear-pedaling Alexandr ...

The wheel is regarded as one of the oldest and most important inventions, which is, according to most authorities, originated in ancient Mesopotamia in the 5th millennium BC, originally in the function of potter's wheels. The wheel reached India with the Indus Valley Civilization in the 3rd millennium. In China, the wheel is certainly present with the adoption of the chariot in ca. 1200 BC, and Barbieri-Low (2000) argues for earlier Ch ...

Wheels are used in conjunction with an axle, either the wheel turns on the axle or the wheel is rigidly attached to the axle which then turns in bearings in the body of the vehicle. The mechanics are the same in either case. The low density of friction (compared to dragging) is explained as follows: the sliding distance is reduced, because the sliding takes place between the wheels and the axles or between the axles and the bearings the coefficient of kinetic friction μ for ...

A chain lock is a lockable chain. It often has a key or a combination lock attached to it. A long enough chain can pass through both wheels, the frame and attach the bicycle to an immovable object. Chains vary widely in their security level. If the chain itself is simply purchased from a hardware store, it can easily be cut with a relatively inexpensive pair of bolt cutters. Chains specifically designed for use in locking bicycles are also available. These chains are made of a much harder metal and the links are often shaped ...

Cable locks are in many ways similar to chain locks. Cable locks often come with the locking mechanism already permanently integrated. Otherwise, a length of cable with loops on both ends can also be used. The main advantage of cable locks over chains is the ease of transporting them. Many cable locks are made of spring cable that automatically coils itself when released. Even a straight cable can be coiled by the user into a more managable shape than a chain. Cable locks, however, are not secure. They are only sufficient for use in low-risk areas since even the largest diameter ...

Race bike components (excluding frameset, fork, wheelset, bars, stem, pedals, saddle and seatpost) is collectively referred to as the groupset. The quality of the groupset determines how refined the bike feels, how much maintenance it requires, and contributes to the performance of the bike. The two major groupset manufacturers of complete groupsets for racing bicycles are Shimano and Campagnolo. The companies have different design philosophies, and some cyclists have great brand loyalty for one or the other. Other companies that produce ind ...

For recreational cycling, the racing bicycle is less popular than the mountain bike. Mountain bikes, through mass production and popularity, are less expensive. A new entry-level mountain bike starts around half the price of an entry-level racing bike. Racing bikes are less durable and less strong than mountain bikes. But unless a rider intends riding on rough tracks a racing bike is more efficient for everyday use. Cyclo-cross bikes, which are ridden off-road, are closer to racing bikes than to mountain bikes. They have wider, treaded tires and cantilever brakes instead of caliper brakes but are still less eff ...

There are many different types of bicycle. See also Category:Cycle types. Mountain bicycles are designed for off-road cycling, and include other sub-types of off-road bicycles such as Cross Country (i.e."XC"), Downhill , and to a lesser extent Freeride bicycles. All mountain bicycles feature sturdy, highly durable frames and wheels, wide-gauge treaded tires, and cross-wise handlebars to help the rider resist sudden jolts. Some mountain bicycles feature various types of suspension systems (e.g. coiled spring, air o ...

Bicycles and their predecessors were directly driven by the feet. The penny-farthing used a large driven front wheel to increase the top speed. The safety bicycle introduced driving the rear wheel via a chain. An early multi-speed bicycle used a double-sided rear wheel, with different-sized sprockets on each side. To change gears, the rider would stop and dismount, remove the rear wheel and reinstall it in the reverse direction. One example of this type of bicycle is in the Science Museum (London, UK). Derailleur systems were first developed in the late 1800s, but the modern cable-operated parallel ...
