Aero Bike
Aero bike also known as "Aerodynamic bike" is a type of road bike that uses aerodynamics principles in its operation. The bike's geometrical makeup allows the hands and body position of the rider to change given the terrain, rider's preference, and race situation. The term is also used for aerodynamic motorcycles. History The first construction of aero bike started out as a styling project that featured an extended aerodynamic front with spoilers and advance guard bodywork in early 1985. In the same year, the first aero bike named "Aero-D-Zero" was constructed around a steel trellis frame and bevel drive Ducati motor of Mike Brosnan. The bike was first used in March 1987 BEARS speed trial. It later won the 1988 and 1990 speed trials with speeds of 242.72 km/h and 247.80 km/h respectively. Meanwhile, increased use of aero bikes was seen 1989 when US road riders started showing great concern with aerodynamics in bicycle riding games. That was when Greg LeMond won the ...

Road Bicycle
The term road bicycle is used to describe bicycles built for traveling at speed on paved roads. Some sources use the term to mean racing bicycle. Other sources specifically exclude racing bicycles from the definition, using the term to mean a bicycle of a similar style but built more for endurance and less the fast bursts of speed desired in a racing bicycle; as such, they usually have more gear combinations and fewer hi-tech racing features. Certain of these bicycles have been referred to as 'sportive' bicycles to distinguish them from racing bicycles. Compared to other styles of bicycle, road bicycles share common features: * The tires are narrow, high-pressure ( or higher), and smooth to decrease rolling resistance * The handlebars are bent ("dropped") to allow the rider position to be leaned forward and downward, which reduces the forward vertical cross sectional area and thus highly reduces the air resistance * They usually use derailleur gears; however, single-speed ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier than air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simu ...

Greg LeMond
Gregory James LeMond (born June 26, 1961) is an American former professional road racing cyclist, entrepreneur, and anti-doping advocate. A two-time winner of the Road Race World Championship (1983 and 1989) and a three-time winner of the Tour de France (1986, 1989, and 1990). LeMond is the only American male to win the Tour de France and is considered by many to be the greatest American cyclist of all time, one of the great all-round cyclists of the modern era, and an icon of the sport's globalisation. LeMond began his professional cycling career in 1981. In 1983, he became the first American male cyclist to win the Road World Championship. LeMond won the Tour de France in 1986; he is the first non-European professional cyclist to win the men's Tour. He was accidentally shot with pellets and seriously injured while hunting in 1987. Following the shooting, he underwent two surgeries and missed the next two Tours. At the 1989 Tour, he completed an improbable comeback to win in ...

Tour De France
The Tour de France () is an annual men's multiple-stage bicycle race primarily held in France, while also occasionally passing through nearby countries. Like the other Grand Tours (the Giro d'Italia and the Vuelta a España), it consists of 21 stages, each a day long, over the course of 23 days, coinciding with the Bastille Day holiday. It is the oldest of the Grand Tours and generally considered the most prestigious. The race was first organized in 1903 to increase sales for the newspaper '' L'Auto'' and is currently run by the Amaury Sport Organisation. The race has been held annually since its first edition in 1903 except when it was stopped for the two World Wars. As the Tour gained prominence and popularity, the race was lengthened and its reach began to extend around the globe. Participation expanded from a primarily French field as more riders from all over the world began to participate in the race each year. The Tour is a UCI World Tour event, which means that th ...

Laurent Fignon
Laurent Patrick Fignon (; 12 August 1960 – 31 August 2010) was a French professional road bicycle racer who won the Tour de France in 1983 and 1984 and the Giro d'Italia in 1989. He is former FICP World No. 1 in 1989. He nearly captured the Tour de France for a third time in 1989 before being edged by Greg LeMond by 8 seconds, the closest margin ever to decide the Tour. Fignon won many classic races, including taking Milan–San Remo back-to-back in 1988 and 1989. He died from cancer in 2010. Early life and amateur career Fignon was born in Montmartre, Paris. His family moved to Tournan-en-Brie in 1963, where he lived until he left for Paris at age 23. His first sport was football and he got as far as playing for his ' or area. Friends encouraged him into cycling and he rode his first official race in 1976, which he won. Fignon's parents did not want him to race, and he raced without them knowing. He won four more races in his first year, but only one in his second year. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fixed-gear Bicycle
A fixed-gear bicycle (or fixed-wheel bicycle, commonly known in some places as a fixie) is a bicycle that has a drivetrain with no freewheel mechanism. 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. Most bicycle hubs incorporate a freewheel to allow the pedals to remain stationary while the bicycle is in motion, so that the rider can coast, i.e., ride without pedalling using forward momentum. A fixed-gear drivetrain has the drive sprocket (or cog) threaded or bolted directly to the hub of the back wheel, so that the pedals are directly coupled to the wheel. During acceleration, the pedal crank drives the wheel, but in other situations, the rear wheel can drive the pedal cranks. This direct coupling allows a cyclist to ...

Hybrid Bicycle
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. Hybrids typically borrow the flat, straight handlebars and upright seating posture of a mountain bike, which many bicyclists find comfortable and intuitive. Hybrids also employ the lighter weight, thinner wheels and smooth tires of road bikes, allowing for greater speed and less exertion when riding on the road. Hybrid bikes often have places to mount racks and bags for transporting belongings, much like a touring bike. Hybrid bikes have spawned numerous sub-categories satisfying diverse ridership. They are classified by their design priorities, such as those optimized for comfort or fitness — and those offered as city, cross or commu ...

Racing Bicycle
A racing bicycle, also known as a road bike is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI). Racing bicycles are designed for maximum performance while remaining legal under the UCI rules. They are designed to minimise aerodynamic drag, rolling resistance, and weight, and balance the desire for stiffness for pedaling effiency with the need for some flexibility for comfort. Racing bicycles sacrifice comfort for speed compared to non-racing bicycles. The drop handlebars are positioned lower than the saddle in order to put the rider in a more aerodynamic posture. The front and back wheels are close together so the bicycle has quick handling, which is preferred by experienced racing cyclists. The derailleur gear ratios are closely spaced so that the rider can pedal at their optimum cadence. However, racing bicycles must retain the ability to maneuver safely within a tightly-packed pe ...

Time Trial Bicycle
A time trial bicycle is a racing bicycle designed for use in an individual race against the clock. Compared to a road bike, a time trial bike is more aerodynamic, has a shorter wheelbase, and puts the rider closer to the front of the bicycle. It may have either solid disc or spoked wheels. Since the cyclist in a time trial is not permitted to draft (ride in the slipstream) behind other cyclists, reducing drag of the bicycle and rider is critical. Time trial bicycles are similar to triathlon bicycles. Triathlon bicycles have a steeper seat tube angle, which pushes the hips forward and saves the hamstrings for the run. TT bicycles have to follow International Cycling Union (UCI) rules. UCI requires that the saddle nose of the TT bicycle must be 5 cm from the centre of the bottom bracket.

Velomobile
A velomobile (); velomobiel, velo, or bicycle car is a human-powered vehicle (HPV) enclosed for aerodynamic advantage and/or protection from weather and collisions. Velomobiles are similar to recumbent bicycles, pedal go-karts and tricycles, but with a full fairing (aerodynamic or weather protective shell) and are not to be confused with purpose-built mobiles for racing or speed records fully faired vehicles with two wheels, generally called streamliners. Streamliners have set many speed and distance records. Though fast in their own right, velomobiles are considered much more suitable for the street than two-wheeled streamliners. Using three or more wheels can have advantages for everyday use, including the ability to stop and start unaided, better stability, cross-wind handling, etc., though there are arguments made that the multiple track machines (three or more wheels) have aerodynamic disadvantages due to the drag of the extra wheels and the surface contact points.
