Long tours are especially comfortable on some of the long wheel based recumbents. You can ride all day and not have any sore spots. Also, as you sit in a more natural posture, your neck does not get sore. And you see more of your surroundings. Stress Injuries Recumbents are often a way whereby people with repetitive stress injuries to the wrist, neck, or back can continue to ride bikes. Quite often such injuries make it impossible to bear any weight on ones hands, as is necessary when leaning on the handlebars. Injuries to the back or neck can also keep people off a regular bike, but seldom present a problem for recumbent bikes. Cycling is still possible with many such injuries if the position on the bike is changed.

But first I would like to mention the fact that often people choose a recumbent after they have many years of using other bikes, and after they have reached an age where they are no longer socially insecure. In prior years, recumbent riders were overwhelmingly middle aged. Lately you are starting to see more young riders, but still virtually no teenage riders. This may well change, as recumbents become more common, not to mention cheaper. Comfort, one of the most frequently cited reasons for riding a recumbent bike is the comfortable seat. Many people find the having weight on their arms or wrists is unbearable for longer periods with advancing age. Others just never seem to get used to a typical bike seat and find the lawn chair like seats of recumbents more comfortable. Make no mistake about it recumbents are very comfortable. However, many recumbent enthusiasts go way eva overboard in denigrating the typical bike seat, claiming they would never go back to that "horrible" seat. However, the upright's seat would not seem so uncomfortable if the rider rode more frequently.
you can also climb very steep hills because Trikes have incredible gearing (some as many as 72 gears and also because you do not have to maintain enough speed to balance as you would on a two wheel vehicle. . you can set the brake, and stop to rest anywhere without getting off the bike. Most commercial recumbent trike designs are of the "tadpole" design with two front wheels and one rear wheel. The trike pictured here. Greenspeed, touring Trike manufactured in Australia but sold the world over, available either as completed bikes or kits to build your own. Reasons for Recumbents, there are several good reasons to ride a recumbent bicycle. I will cover these below in greater detail.
Uss is quite comfortable once you are use. There is nothing in front of you. Some riders find this arrangement makes it easier to get on and off, due to not having to duck under the bars. Not Just Bicycles, not all recumbents are bicycles. . Trikes have a special appeal to the touring crowd as you are never at a loss for a place to rest, and the carrying capacity is great. Plus, your full loaded bike does not try to fall over the minute you turn your back. . Trikes also appeal to those users with balance problems, salvaging an otherwise lost essay love of cycling. There is no learning curve, you can ride one instantly. .essay
Steering Arrangements, within the three above general categories of bike geometry, there are two common arrangements of the steering mechanism. These varieties each have their own strong points and near fanatical adherents. Both work, both are easy to learn to use. Above seat steering (ASS) recumbent have handlebars above the seat, usually about chest high. This arrangement is often said to be more comfortable for the beginner than is under seat steering. Above seat handlebars also lead to a more aerodynamic configuration on the bike as your arms are in front of you and therefore do not present an additional wind target. Under seat Steering, under seat Steering (USS) has the steering assembly under the riders seat and handlebars protruding out from under either side of the seat. This usually entails some sort of linkage to the front wheel, except in the case of short wheel based machines, which have the front wheel very close to the rider.

Recumbent Variety, there are a lot of different recumbent shapes and sizes. Once you review break the "rules" and deviate from the diamond frame design there is little to hold you back from trying new designs and new shapes. The two most common classifications of recumbents are based on where the front wheel is in summary relation to the rest of the bike. . These are short wheelbase and Long wheelbase. . There is arguably a third category called compact long wheelbase, but the difference between this and the other categories is blurred and indistinct.
Short, short, or short wheel based bikes usually have the front wheel about at the riders knees, while the cranks are way out in front. These tend to be speedy bikes. Sometimes this yields a harsher ride as you are sitting almost on top of the front wheel. Long, long Wheel Based bikes have the front wheel out in front of the cranks like a conventional bike. Such bikes have larger turning radiuses, and some of the smoothest rides of any bike. These bikes also tend to be the lowest bikes, often having the seat less than a foot above the pavement.
What are these things, recumbent (meaning seated) bikes have been around for quite a while, but have never garnered a significant share of the market. The last I heard, they had just slightly more sales than Tandems, and you know how rare those are. Yet lately you are starting to see them in increasing numbers. Recumbents or "Bents" as they are often called in the us and Canada (but seldom in Britain due to another connotation of the word) started out as a tinkers project. Often they were, and some still are, assembled in garages out of pieces and parts of cannibalized bikes by guys with a welding torch in their hand and a gleam in their eye.
Today, there are a couple dozen manufactures of quality production recumbents in the us, europe, australia, and the Orient. Out of this environment came a few bikes with very nice handling characteristics, a fair bit of speed, and a great deal of comfort. Comfort seems always to be measured against the alleged horrors of the regular bike seat, usually with dramatic exaggeration thrown in for good measure. Make no mistake about it, the garage mechanics bike and the production recumbents which descended from them are comfortable. And yes, they are easy to ride, although in your first five minutes on one you may think me daft for saying. They ride differently, they steer differently, starting and stopping is different, and climbing hills requires a different approach. By and large they are quite fun to ride. The "Recumbent Grin" is the most noticeable attribute of a new bent pilot. (That term "pilot" comes up often among recumbent riders because the feeling of banking into turns as you swoop around corners has much in common with feelings you get while flying in small planes).

Hand Cycle, by, john Andersen, youve probably seen them, those odd shaped bicycles having more in common with lawn furniture than typical bicycles. Perhaps youre wondering what they are all about and why are there starting to be more of them around. You probably would like to try riding one some time, and wonder if they are easy to ride. Or perhaps you just decided to see if this article would explain just what kind of madness would make a healthy looking bicyclist climb aboard a pedal driven lawn chair. Im referring to recumbent Bicycles of course, those sit-down bikes, which are pedaled with the cyclists feet out for in front, while the rider is seemingly relaxing in a mesh seat looking for all the world like it is no work at all. In this article Im going to attempt to answer your questions in a balanced way, because there is a lot of hyperbole both Pro and Con. Let me start right off by saying i use a recumbent and three diamond-frame (regular) bikes as well as a tandem. I like them all, and have spent enough time on each of the types to know the faults and well as the strong points.
damage indicators. Tetsuya theodore fujita,. Tetsuya theodore (Ted) Fujita (Oct. 23, 1920 - nov. 19, 1998) was a pioneering meteorologist who revolutionized the study of severe storms. Fujita was the first person to realize that there are multiple vortex tornadoes, downbursts and microbursts. Fujita developed the scale used for measuring wind speed, linking damage to estimated wind speed. This scale is called the fujita-scale or the f-scale.
Theodore fujita developed a method for categorizing tornadoes by looking at how much damage they cause and using this to estimate the wind speed. This system is called the f-scale or Fujita Scale; it classifies tornadoes by their estimated wind speed, which is determined by looking at how strong the wind must have been to cause the resulting damage. Tornadoes are classified into five categories, f-0 through F-5. F-0 tornadoes are the mildest. F-5 tornadoes are the most dangerous (and the rarest). F-0 40-72 eksempel mph, light damage, chimney damage, tree branches broken. F mph, moderate damage, mobile homes pushed off foundation or flipped over. F mph, considerable damage, mobile homes demolished, trees uprooted. F mph, severe damage, roofs and walls torn down, trains overturned, cars thrown around.

Tornado Classification, the f-scale: Wind Speed and Damage. It is not easy to measure wind speed in a tornado. This is because a tornado usually destroys local measuring equipment, and also because tornadoes only essay exist for a short time at random places and they are gone before meteorologists can study them. Wind speed is usually measured by a device called an anemometer, which has cups that spin around a vertical axis in the wind (the beaufort wind scale rates, on a scale of 1 to 12, how strong the wind is). Severe tornadoes, however, can destroy these relatively fragile devices. There are other methods of measuring wind speed (including Doppler radar but measuring the wind during a tornado is not easily done because tornadoes exist for such a short time. Meteorologists (weather scientists) may not even know about a tornado until after it has dissipated, since tornadoes usually only last for a few minutes and travel for a relatively short distance. Before 1971, tornadoes were not ranked at all.
