Pulse charging freight cargo trikes vehicle batteries
Pulse charging freight electric car battery is not continuous, square-wave fixed voltage to the battery, the charging current is large. Since the initial charge and negative plates are in a state of lead Folding electric bikes, a greater ability to accept, but also because of the discontinuity of the square wave, the waveform between each intermittent stopped there, to the electrode active material in a sufficient reaction, Electric Bikes, balanced opportunities both inside and outside the material, so the initial charge faster. With the reduction of the plate material continuously, rising voltage, the charging speed continues to slow down, the reaction rate decreases the active substance, gradually accumulate a large number of plates around the charged ions, surround the plate, so that the plates are isolated to prevent subsequent charged ions reach the active substance. Brand electric tricycle when the limit is reached when the plate potential (close charge termination voltage), galvanic effect almost cease. The polarization point, turn on the water to decompose around the plate, showing a lot of bubbling and water evaporation, cathode surface adsorption of large amounts of oxygen, a lot of negative surface adsorption of hydrogen, when the voltage is called "gas point."

Italy Electric scooters market
Italy 's heavy industry , light industry , tourism is highly developed , of course, a motorcycle is Folding electric bikes well developed. However, due to educational level and taste of our people has been in a low state, so many European brands are not perceived American people . The other is the multi- Italy by SMEs , to plant for small manufacturers to determine the brand of people who , to their knowledge is certainly very small. 1946 film " Roman Holiday" swept the world in which romantic love story infect everyone, spread so far. Hepburn scooter bike while driving is Piaggio VESPA from Italy , also known as the only士帕or wasp , the car does not like the Japanese motorcycle pedal plastic shell , but the whole steel frame repression , so durable high degree . 1940s , VESPA 50 years can be seen. Currently has 50 million worldwide sales . India 3 million , Vietnam 1 million , while China is less than 10 . And the country is currently Piaggio Zongshen cooperation. Now Cargo bike has acquired most of the European motorcycle manufacturers , namely Apulia, Spain Derby, Ji Leila , AIDS and so many ancient brands . Most of the French flag motorcycle parts are almost always Piaggio . Ducati motorcycles in luxury, but not a bad opening Ducati said. Malaguti , both heavy locomotives, quality and quality can Agusta below par . MV Agusta , nicknamed motorcycle Lamborghini, two Ferraris , current and Lifan cooperation. Bombardier , the car did not see Spider-Man , that is Bombardier . Italian riding the Czech Republic, and produced full plate as Piaggio scooters . Another is the production of helicopters Agusta , Piaggio and Bombardier is the production of private aircraft. Italian motorcycle brand still many, and Japanese motorcycle is different, the Italian motorcycle is better, durable, not easily broken , perfect design , as opposed to just imitate , assembled ( little Japanese motorcycle design , assembly of many ) marketing Japanese motorcycle , the Italian motorcycle if people want to know , just step up publicity efforts to gain a foothold . Of course , the Italian motorcycle is the most threatening of the Japanese motorcycle trader .

Part of the bicycle
In 1888, Ireland's veterinary Dunlop, get inspiration from healing cow stomach gas expansion, he spent in home garden Folding electric bikes rubber and glued into round, play enough gas, mounted on bicycle wheels, to ride a bike race, incredibly, aroused people's great interest. Pneumatic tire is a landmark in the development history of the bicycle in the world, it increases the flexibility of the bicycle, won't because the road is rough and vibration; Greatly increased the speed at the Three wheel bikes time, reduced the wheels and road surface friction. So, it is fundamentally changing the bike ride performance, perfect the use function of the bicycle. Therefore, since the end of the 18th century, until the beginning of the 20th century, the invention of the bicycle and improvement, through about 200 years, there are many to strive for, to evolve into the style of this ride freely now.
Of a bicycle
(1) body parts: including frame, front fork, handlebar, saddle and front fork fitting and so on, is the main part of the bicycle.
(2) transmission parts: including the pedal, crank, sprocket, chain, axial and flywheel, etc., by human pedaled pedal, drive a drive wheel rotation, through the above drive forward.
(3) action part: front and rear wheels, including front axle parts, spokes and rim (circle), tires, etc.
(4) safety device: including brake (brake), car lights, bell, reflectors, etc.

(3) action part: front and rear wheels, including front axle parts, spokes and rim (circle), tires, etc.
(4) safety device: including brake (brake), car lights, bell, reflectors, etc.
The origin of the word
the first time in the word, and is still in use. In 1790, a French name, with his mind he loved so much. One day, he walked on a street in Paris, because the day rained, Folding electric bikes a lot of rain, on the road is very bad. All of a sudden, a carriage jumped from behind, and the road is narrow, the carriage is very wide, the schiff, hide to hide but not knocked down by a car, or was spattered mud and rain. Others saw it, sorry for him, but also gas straight scold, want to shout the cart stopped, reasonable representations. The schiff, but murmured: "don't cry, don't shout, let them go." The carriage walked away, he was standing on the side of the road. He was thinking: the road is so narrow, pedestrians and so much, bike why can't the carriage structure changed? Should the carriage along the cut off half, before and after the four wheels to two wheels... He thought, so home will begin to carry on the design. After repeated experiments, in 1791 the first Three wheel bikes "Trojan horse" of the car made out. Before and after the car has two wooden car wheels, intermediate connecting beam, Ann on a bench, like a toy. Because the car hasn't drive chain, by cyclists foot pedal, the car can move forward slowly, but also no steering device, the car can go straight, don't turn, go out to ride soon tired covered in sweat. Just a new things is not so perfect. The schiff, don't lose heart, he continued to think of some way to improve it. Unfortunately, he died soon. In Germany in 1816, has a look man named Lin dera ismail, he from CunDong this forest, every day go to the village west of the other trees, so every year. He thought, if people sit in the car, stop-go, follow one's inclinations, not very natural and unrestrained? DE les starts to make wooden wheel car, with the schiff, made almost. However, on the front wheel and a control direction of traverse to the child, to change the way forward. But when the cycle is still want to use two feet, hit the stamped on the ground, rolling forward to push the car. When the DE les to ride a bike to go out, test, was laughed at by many people along the way. In spite of this, he is very like your writing the "cute little pony". A DE les when cycled around driving a carriage, the driver laughed at he said his car slowly, so he and the driver said: "your letter not letter I car faster than your carriage" and they two made a bet. Distance from CunDong to village west of a back and forth, results DE les is faster than the driver for more than an hour. In 1840, England's blacksmith McMillan, got a battered "cute little pony". He put the crank in the rear axle and then use join the pedal in front of the crank and connecting rod, and the front and back with iron, the front wheel, rear wheel small. When the cyclist pedaled pedal, the car will be on their own motion, ran forward. In this way, really make the cyclist's feet off the ground, with alternating feet trample move into the wheel rolling, greatly improved the driving speed. In 1842, the macmillan ride this kind of car, ran 20 km a day, due to accidentally hit the car too fast, hit a little girl on the road, which was caught by the police, and impose a fine. The charges are "wild ride". Bicycle in 1861, France michaud of father and son, originally profession is the carriage repairman, they installed in the front wheel can turn the pedal board; Top of the saddle seat frame of the car in front so that unless technology special superb ride a bike, or grasp the handlebars, will fall down from the car. They put the two rounds of car box (ossuary) dubbed the "bicycle" James, and exhibited in Paris in 1867, fair, let the audience an eye-opener. In 1869, Britain's Renault after watching the French bicycle, feel the car is too heavy, start thinking about how to put the bike done some light. He USES the steel wire spokes to tighten circle as the wheel; At the same time, the use of thin steel bar to make the frame, the front wheel of the car is bigger, the rear wheels. To reduce the weight of the bike itself. Since the schiff, has been to Renault, it made the five types of bicycles and modern bicycles difference is bigger.

A top speed of bicycles
Bicycle top speed of 268.831 kilometers, is on October 3, 1995 by the Dutch Fred roma's bell by bonner, salt flats in Utah in the United States. This Folding electric bikeswas in large part thanks to his leading vehicle produced by low pressure air pockets. And people's normal walking bike is 15 km per hour. Chrome molybdenum steel frame: 90 s, bicycle frame with chrome molybdenum steel system for the mainstream. Its distortion performance and good Three wheel bikes properties, high temperature will not affect the material, when welding the price is cheap. But the weight is heavy, easy to oxidation. Appeared to overcome its shortcomings, give play to the advantages of the new material, chrome molybdenum steel frame again. Carbon fiber frame: light and absorb the impact of the ground, quick material of backwash force, etc., is the ideal bike frame material. Carbon fiber grade, tonnage high elasticity are also higher and higher, the price is expensive. There are several kinds of methods, such as with adhesive on the mould, overlapping carbon fiber, heat treatment, solidification, molding, etc. The proportion of titanium frame, titanium is 55% lighter than steel, it is not easy to oxidation. In order to improve the tensile strength, has mixed aluminum, vanadium and titanium alloy. Such as welding needs to be done in a vacuum processing complex, frame price expensive. Aluminum frame, aluminum alloy frame of light and strong rigidity. After special processing a frame of only 1 kg in weight. Aluminum pipe tends to large diameter, to alleviate the too strong rigidity, small cars fork pipe and adopt absorb the impact of carbon fiber and other popular attention.
