The World’s Smallest Motorcycle

upendra singh rathore — Fri, 21 May 2010 15:36:48 +0000

In 2003, Tom Wiberg from Sweden built a motorcycle with a front wheel diameter of 16 mm (0.62 inches) and a rear wheel diameter of 22 mm (0.86 inches). He rode it for more than 10 m (32.8 feet) in Hökerum, Sweden. The motorcycle has a wheelbase of 80 mm (3.14 inches), a seat height of 65 mm (2.55 inches), weighs 1.1 kg (2.4 lbs). It powered to a top speed of 2 km/h (1.24 mph) by its 0.22 kW (0.3 hp) engine. In my opinion, this was built by the designer just to obtain the Guinness World Record for the World’s Smallest Motorcycle.

History of bmx bicycle

upendra singh rathore — Sat, 17 Apr 2010 15:11:53 +0000

BMX started in the early 1970s when children began racing their bicycles on dirt tracks in southern California, drawing inspiration from the motocross superstars of the time. The size and availability of the Schwinn Sting-Ray made it the natural bike of choice, since they were easily customized for better handling and performance. BMX racing was a phenomenon by the mid-1970s. Children were racing standard road bikes off-road, around purpose-built tracks in [California]. The 1972 motorcycle racing documentary On Any Sunday is generally credited with inspiring the movement nationally in the US; its opening scene shows kids riding their Schwinn Stingrays off-road. By the middle of that decade the sport achieved critical mass, and manufacturers began creating bicycles designed especially for the sport.BMX Freestyle is now one of the staple events at the annual Summer X Games Extreme Sports competition and the ETNIES backyard jam, held largely on both coasts of the United States. The popularity of the sport has increased due to its relative ease and availability of plg, China. At the games, Latvian Māris Štrombergs and Anne-Caroline Chausson of France were crowned the first Olympic champions in Mens and Women’s BMX Racing, respectively.
Many great BMX riders go on to other cycling sports like downhill such as Australian Olympian Jared Graves, former “golden child” Eric Carter, and youth BMX racer Aaron Gwin. Conversely, Mountain Bike racers sometimes cross over to BMX Racing, such as 2008 Olympic Bronze Medalist conor of the USA.

The technology and design of the bike is focused on providing maximum performance at the circuit.Other important technical features making a significant contribution to the performance of both the road and race bikes are the crank and pistons. These are two more areas where the racers must remain absolutely standard. But there’s much more to the YZF-R6 than its engine.The massive air induction system is another M1-derived feature, going straight through the machine’s headstock and using the inside of the frame as the air cleaner box.

Mountain bike racing (MTB)

upendra singh rathore — Mon, 30 Nov 2009 14:17:35 +0000

The first mountain biking world cup series took place in 1991. Its nine-race circuit covered two continents—Europe and North America—and was sponsored by Grundig.In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA.

There are many types of mountain bike racing-

Freeride - Freeride (FR) competitions are not so much a race as they are a competition of skill.

Downhill- Downhill (DH) racing is a time trial event. Riders start at intervals that can vary from 30 seconds to three minutes-depending on the stage of the competition – and the rider with the lowest time wins.

Cross-country -Cross-country (XCO) racing is held on a varied terrain circuit, it is normally around 6-8 kilometers (km) and is always a massed-start race. In this type of race elite, U23, and Junior Expert riders at UCI sanctioned races, are allowed technical assistance.riders in the same team can help each other at any point in the race.

Super D – Super D (SD) is a blend of cross-country and downhill. Most of the race is downhill, on trails similar to the downhill segment of a cross-country race. There are also short (100–500 m) uphill sections which make the use of downhill bicycles difficult, as a result, most riders use cross-country or ‘trail bikes’.

Dual Slalom/Dual – Dual Slalom (DS) is a ski-inspired event which pits two riders against each other on two identical man-made tracks side-by-side with the same jumps and berms, with a rider on each track, and the first across the line wins.

Four cross -4X also replaced Dual in the UCI World Cup series in 2002. Inspired by the dual format and by BMX racing, this event pits four riders on the same course from starting gates to finish. There can only be one winner per event, so the races can quickly eliminate riders making the progression faster for a day’s events.

Enduro – Enduro (ND) is a relatively new development that has its roots in Marathon mountain biking.Only one member of the team can be on the course at any one time, and it is a competition not to finish first, but to complete the greatest number of laps before the end of the event.

Bike trials - Slow negotiation of man-made and natural obstacles where setting a foot down constitutes a penalty.

Dirt jumping – Dirt jumping (DJ), similar to freeride, it is a competition of skill, differing that it involves the rider to jump off mounds of dirt to perform the best tricks with the best style.

Stage Races – Stage Races consist of several races – ’stages’ – ridden consecutively, usually over a period of several days.

Mountain bike(MTB)

upendra singh rathore — Thu, 19 Nov 2009 16:53:35 +0000

A mountain bike which is also called as MTB or ATB ( or all terrain bicycle) is a bicycle created and made for off-road cycling, including jumps, and traversing of rocks and , and steep declines, on dirt trails, logging roads, usually called mountain biking.

mountain bikes usually have only a small amount of front and rear suspension and are relatively light, which is achieved via the use of lightweight materials and construction in both frame and components. As a consequence, XC bikes are often less durable than other types of mountain bikes when used outside of their intended purpose.

The gear ratio chosen depends on the terrain being ridden, the strength and skill of the rider, and the size of the bike . Often single-speeds are fully rigid, steel-framed bikes. These are typically ridden by very fit individuals on mild to moderate cross country terrain.

Enduro/all-mountain (AM) bikes bridge the gap between cross-country and freeride bikes, typically weighing between 14 to 16 kg.
