Why is the speed the car has Electric Tricycle

Domestic market because consumers have not been able to appreciate the charm of the speed , so at this stage womens mountain bikes has not been widespread, but in Japan and Western countries shift is already very common ( 50% in the Japanese bikes are shifting car ) . Of course, the reason is that no maintenance . Recent new products as well as sensors and micro-motors Electric Bicycles through the computer to automatically shift the automatic transmission system .

What kind of bike best suited for you?

The first is to see what your bike is designed to generally work, school , shopping , then you can use the normal light trucks , preferably relatively large basket , you can put the bag or something. There can be bought if the conditions inside or outside the Electric Bicycles vehicle speed gear bike.
If you ride on the road or bridge slopes , you also feel the uphill on the bridge was tired a lot of trouble , then you should not choose a bicycle transmission .
If you ride on the road is not flat, paved roads , you should choose a wider tire and there is a bicycle transmission .
If you are one day long distance riding , you should choose a bike with narrow tires and transmission . If it is a short Folding bicycle distance , then you should choose light vehicles.
If you are in a place often rains , you should choose a bike with mudguards , more opportunities if riding at night , then you should choose a bike with lights and so on.
In the bike shop often has a variety of appearance, color bike , so before you go to a bike shop , it is best according to their actual situation , you will need your own bike to determine what kind of Yan , and then to the bike shop to buy

Assembly Electric Tricycle

Good parts if assembled properly, it Battery powered bikes will go through as neither attentive design architect , nor experienced craftsmen to build the house, make your nervous all day , for fear it would collapse. So , if you do not want to buy later regret , you should be Electric Tricycle aware of this knowledge .

I do not know now when Electric Bikes riding gear in the first few paragraphs ?

Has now shifting to the digital display , digital display can just look at the latest products as well as using a computer LCD 's FLIGHT DECK electronic display systems. The display system can also display 17 kinds of function time, average speed , total Folding electric bikes distance riding . Previous transmission system needs fine adjustment ( now also part of the variable speed drive needs fine-tuning ) , but with the SIS (SHIMANO INDEX SYSTEM) successful development function , making many of the bikes are fitted with sis system , as long as the press speed when shifting the to as "flap " sound and complete the shift , it has no need to worry about how to operate it. Many people mistakenly believe that the bicycle is equipped with a transmission speed in Battery powered bikes order to speed up riding , in fact, people can send a maximum power of only 0.4 horsepower. Transmission is designed to help people easily play these maximum horsepower out of the tool.

What is a Electric Bicycles

Mounted on the frame of a wide variety of parts has its own role , for example , is to make bicycle safety brake to stop ; pedal power is transmitted to the wheels , etc., specialized factory Folding electric bikes production and sale of these parts is called bicycle parts manufacturers, parts manufacturers are famous annual development of new products, which also provided to the major bike manufacturers, and then appeared on folding bicycle the market .

Battery formation process irreversible sulfation main reasons include

Frequent deep discharge and over-discharge, no timely charge or charge less; deficit in the long-term status of the battery power left unused that poor memory; battery pack Cargo trikes inconsistent battery performance, there are differences too much behind the battery; performance of a battery pack a battery's capacity is significantly lower than the other battery, causing the entire battery voltage drops, the first to be fully behind the battery because the remaining battery charge and the Folding electric bikes form still charging overcharge, discharge the battery behind because of the first to be vented to form over-discharge, resulting in further exacerbate sulfate, making more serious degree of backwardness, creating a vicious cycle; electrolyte density is too large; battery ambient temperature changes.

Bicycle design Delaisse 1817

In 1766 , a group of monks in the repair work of Leonardo da Vinci manuscript in 1490 , I found the earliest prototype bike , but did not actually manufacture it, stopping only in the imagination stage. Frenchman Siv Mubarak on a rainy day , the streets were splashing through the mud wagon , which splashed his whim : wagon so wide , it should be cut down half of the carriage , four wheels front and rear wheels ...... into two . So in 1791 , the first aircraft to travel by "Trojan Wheel" car was born. This car has around two wooden wheels attached to the middle of the beam , a bench above the safe , like a toy. Zheliang "Trojan Wheel " Although neither the drive chain , nor steering, but generally considered to be the earliest human bicycle . In 1818, Germany look林人德Royce also making a car wheelers , he added a steering wheel to control the direction of the front wheels , you can change Womens mountain bikes direction. But when you still have to spend two pedal cyclists , pushing the car to roll forward . In 1840, the Scottish blacksmith Macmillan , on the basis of a wooden -wheeled Delaisse invention on improvements. He installed on the crank axle of the rear wheel , and then link the pedal crank and connecting the front and rear wheel are used iron , front large and small rear wheels. Such real people 's feet finally leave the ground , stepped on the feet alternately moving vehicle driven wheels rolling forward . In 1842, Macmillan ride this car one day to walk 20 kilometers . In 1861 , France Michaud and his son , mounted on the front wheel can rotate the pedal board, saddle rack in the front of the car above . They put the car dubbed the "bicycle " of James, and exhibited at the 1867 Paris Exposition . Michaud from Siv Mubarak until his son , Electric Bicycles making their bikes and modern bikes vary greatly , this bike without a chain of transmission can only be improved in order to improve the speed of the front wheels diameter to achieve, thus causing the vehicle pole high , the diameter of the front wheels even more than the average person 's height , cycling becomes a very dangerous sport , when the rider fell to the ground , it tends to hurt. Cycling truly modern form was born in 1874. British Luosong ingenuity on the bike fitted with chains and sprockets, turning the rear wheels used to push the car forward . 1886 Britain's mechanical engineer John Starley , from the perspective of mechanics, kinematics design a new bike style , fitted with fork and brakes , front and rear wheels the same size , in order to maintain balance and control into steel diamond frame , the first time the use of rubber wheels. Starley not only improve the structure of the bike , but also the restructuring of many tools used in the production of bicycle components for mass production and promote the use of bicycles has opened up a wide road , so he was later known as the "Father of cycling ." He designed bike models like the bike and today has been basically in agreement. In 1888, the Irish veterinarian John Dunlop , get inspiration from bovine heal Stomach swelling in his garden for watering the rubber tube into a round stick and hit enough air mounted on the bike , this is the pneumatic tire beginning. The pneumatic tire is pioneering a landmark in the history of the bicycle , which not only changed the riding performance bikes fundamentally improve the bike and use function .

It is important to brake parts

The quality of the relationship between the brake to secure your safety and that of others, brake power and Folding electric bikes brake braking time is a major factor in the decision is good or bad brakes, so good braking performance, the operating power of light is very important to use. In the Japanese market, there is a more common roller brake, except in the rain can also get satisfactory results as usual, but there will be no noise Battery powered bikes when braking and do not repair.

How to choose a bike

Select the bike is not primarily a good look at the frame , the second look is not good parts, three assembly technology is good to see . After these three factors are combined scientifically to be a good bike.
First, the frame:
1 What is the frame ?
Frame equivalent to the Electric scooters human skeleton , with the frame to put on a variety of bicycle parts . A frame made ​​of iron , aluminum and other materials, according to the angle of the length of the pipe , etc. affect the characteristics of the overall configuration of the bicycle . For example , a good bike ride straight , easy to turn the bike , comfortable riding bicycles , many of these factors are decided from the frame.
2 How can I be a good frame ?
Light , fast , flexible frame and so is one of the objectives pursued , in order to achieve this goal, each frame depends on the manufacturer's process . If the frame is designed according to the characteristics of the material strength and design , welding technology is mature . These have a direct impact on the appearance of the frame , the strength and elasticity. There are more important is painting, painting a good frame electric trike evenly and 3-4 layers of spray paint . Do not underestimate the paint, make the bike easy to maintain good paint , rust . If the frame does not meet the above requirements to loading , then there may not be a straight line to produce a bike ride or difficult to turn , or will soon retire bike.
The frame is composed of what material ?
Most iron frame , but the frame is divided into iron in the iron added to the other extreme frame chrome molybdenum steel, high strength steel , ordinary steel , etc. , after adding the other ingredients , for example can be made thinner pipe, makes the frame lighter overall . Recently, on the basis of the intensity is not reduced , there has been used a frame material other than iron , such as aluminum. Bicycle race to have carbon fiber material using titanium frame .
Second, the component parts
1 What is bicycle parts
Mounted on the frame of a wide variety of parts has its own role , for example , is to make bicycle safety brake to stop ; pedal power is transmitted to the wheels , etc., specialized factory production and sale of these parts is called bicycle parts manufacturers, parts manufacturers are famous annual development of new products, which also provided to the major bike manufacturers, and then appeared on the market .
2 What is the best bicycle parts ?
Simply speaking is both light and strong , and the performance is better . With these conditions because it was easy bike ride , safe and convenient . But to achieve all of the above conditions , you need good material . So, bicycle parts is often a specific factor about bike prices. The best is to be able to participate in the Olympic race bike parts . Regardless of the strength properties of the weight or the best materials are used .
Third, assembly technology
1 assembly technology
Good parts if assembled properly, it will go through as neither attentive design architect , nor experienced craftsmen to build the house, make your nervous all day , for fear it would collapse. So , if you do not want to buy later regret , you should be aware of this knowledge .
2 . Comfort features bicycle
A. Transmission ?
Many people mistakenly believe that the bicycle is equipped with a transmission speed in order to speed up riding , in fact, people can send a maximum power of only 0.4 horsepower. Transmission is designed to help people easily play these maximum horsepower out of the tool.

Bicycle safety performance

Bicycle rider 's personal safety is an important issue , there are countries to develop appropriate standards . China promulgated safety standards include three aspects strength structural parts , brake brake performance and safety devices , including the strength of the former frame and fork assembly , the assembly of the handlebar firmly with fork , front and rear wheel strength .
① impact strength frame and fork assembly : There are two measurement methods. First, the drop weight impact test, the assembly is erected vertically , the top of the front fork 180mm 22.5kg Battery powered bikes disposal a hammer , a hammer impact on the permanent deformation of the assembly does not exceed 40mm, no naked eye crack ; Second, drop test , placing 70kg weights in the saddle at the component, its center of gravity moved to the vertical position of the rear axle , the free fall forward , repeat the test twice , without naked eye cracks. In addition, the frame and fork need for lateral load strength test , the load weight varies by model .
② handlebar assembly firmness and fork : The method is the handlebar mount fork, 25N · m of torque applied to the handlebars womens mountain bikes horizontal pipe ( usually test bars instead) , the handlebar can not rotate.
Before ③, the strength of the rear wheel : The method is to put the corrected wheel spokes and clamping flat , 178N force is applied laterally , one minute later , the permanent deformation of not more than 1.5mm.
④ brake brake performance: test method according to the vehicle 's transmission ratio is divided into two kinds. One is on the trip 5m 5m or more bikes , the specified test speed of 24km / h; another one is on the trip 5m below the car, the speed of 16km / h. There are two wet braking performance and analog dry rainy . In the test speed required before use , the brake , the braking distance is not greater than the dry 5.5m, wet braking distance shall not exceed 15m.
⑤ safety devices: a bicycle should be equipped with a bell or lights , but also a reflector ( commonly known as the back light ) . The reflector is by vehicle headlights or other external light source , the intensity of the reflected light enough to remind each other's attention to protect themselves. The reflector has a front , side and rear reflector 3 kinds . In front of the white, red rear , front lateral white or amber , rear lateral white or red , white or amber pedal .

Daily Electric Bikes

Even if your not a long continued line capacity requirements, you can use one charge 2-3 days, but it is recommended that you charge every day, so that the battery in the light cycle, the battery life will be extended. Some thought that the early use of mobile phone users to folding bicycle recharge the battery after basic use is best done, this view is wrong, lead-acid batteries and memory efficiency is not so strong. Life often is done and the impact on the battery power is relatively large. Most of the charger indicator lights indicate after fully charged, the battery charge into the charge may be 97% to 99%. Although only due to charge 1% to 3% of the electricity, the Folding electric bikes impact on the continued ability of the line is almost negligible, but also form due to charge accumulation, so the battery is fully charged after the lights change or continue to be floating charge as much as possible, but also to suppress cell cure good.

Protect the Battery powered bikes

General Instructions above all on the protection of the charger instructions. Many users do not read the instructions habits, often in addition to looking after the problem was reminded of the instructions to see, often too late, so it is necessary to look at the manual. To reduce costs, and now the Chargers are basically not doing high vibration cargo bike resistant design, this charger is generally not on the trunk of electric bicycles and cars basket. Under special circumstances, must be moved, but also make good charger with foam packaging to prevent vibration bumps. After a lot of vibration through the charger, its internal potentiometer drift, making the whole parameter drift, resulting in abnormal state of charge. The other is the need to pay attention when charging the charger to maintain ventilation, electric trike otherwise it will not only affect the life of the charger, charging status may also affect the thermal drift. This will damage the battery formation. Therefore, to protect the charger is also very important.

Widely used mountain bikes

Mountain bike wheels to roll the car much more than the postal brisk. Their superiority thanks to several Cargo bike factors: Lightweight wheel vehicles, high-quality leather and has a lightweight shaft, high pressure resistance and softness good tires. Introduced a variety of mountain bike parts and their relationship to each other beneath the wheels. Mountain bike wheel tire tire (tire), today there are four mountain bike tire size: 26x2.125, 26xl.75, 26 只 1.5 and the French system specifications 65oB. There are several standard widths after 1984 has been voted one of eight mass market, but it has suddenly appeared like it is rapidly disappearing as the 'variety of 26 "tires fit wheels mounted on the same specification vehicles while 65OB only applies to larger series round: Chen v) J of 26 x2] 25 tire on soft ground has excellent shock resistance and exceptionally strong traction, therefore, the electric trike mountains and sand, this tire is still the first choice, however, no matter how the name, you call it no i Lun mountain biking, off-road vehicle or all-terrain bicycles, bicycle or traveling in the vast majority of the asphalt road.

Specially constructed electric cars

According to different output speeds, respectively, and with different wheel diameter wheels to drive the vehicle traveling at speeds up to 20km / h. Although these electric car styling and installation location of the battery varies, but the drive and control the presence of Three wheel bikes common principles. Such electric bikes are electric vehicles mainstream. Specially constructed electric bike: a small electric vehicles using non-motor-driven wheel. These electric vehicles using side-mount or cylindrical motors, mid-mounted motor, tire friction motor. Generally use this motor-driven electric vehicles, which will be lower vehicle weight, the motor efficiency is Folding electric bikes lower than the hub-style efficiency. In the case of the same battery energy, the use of these motor vehicles are generally shorter than the 5% -10% - wheel vehicle continues the course.

Fashion motorcycle

Harley-known companies - such as Davidson and Indian. In 1907, Harley - Davidson produced the first V-twin engine, compared with the traditional single-cylinder engine that provides twice the power of a motorcycle. This style of engine in the United States 80 years of history in motorcycle Cargo bike manufacturing, occupy a dominant position. In the 1930s, Harley's sales topped the United States of the list; into the 1940s, Harley-Davidson motorcycles in the UK has been challenged because they are lighter, faster; early 1960s, small-displacement Japanese motorcycles influx of U.S. market; 1969,Electric Bikes  Harley-Davidson and American machinery and Foundry merger, capital and resources to strengthen the market; late 1980s, the overall revitalization of Harley-Davidson motorcycle, a motorcycle that is produced every quality assurance.

Cargo trikes

Electric Bicycle ( Figure 2 electric bicycle is the most important accessory motors, electric bike motor basically determines the car's performance and quality. Motors used in large electric bicycles are Cargo bike rare-earth permanent magnet motor , which is mainly divided into high-speed brush + gear motor, brush motor low speed and low-speed brushless motors are three high speed gear motor brush + the best performance , the price is expensive ; low brush motors to be cheaper , but the performance to be worse ; no due to the quality of the brush motor controller is extremely demanding, not many brands listed , the best selection of brand when consumers purchase. ( U.S. Enda lithium bikes ) offer us know , electric bicycles electric bicycle ( hereinafter referred to as electric vehicles ) is with batteries, lithium batteries and other energy as an auxiliary energy, with two wheels , to achieve human riding , electric or electric -assisted bicycles special features . motor is to convert electrical energy into mechanical energy battery , electric drive wheel rotating parts in electric vehicles motors used on its mechanical structure, speed range and there are many kinds of common form of electricity are : gear hub motor with brush , brush gearless hub motor , Folding electric bikes gearless hub motor , brushless geared hub motor , usage tips, high disk motors, motors and other side hung : good ventilation when charging to keep the charger during the charging process if the odor or smell the charger housing temperature is too high , stop charging , check processing .

Electric tricycle classification

Use is divided into household type , cargo type , factory -type models. Because the different uses of technology is not the same electric trike used for household electric tricycle , is mostly a side wheel motor , external frame ( frame on the outside of the wheel ) , the structure of the car is not big shaft of light load , generally around 200KG, motors typically 350-500W, battery 12V20AH battery , suitable for household and Three wheel bikes means of transport. There are also motor home with a large shaft ( shaft , also known as the bridge , back rest , is the connection between the axles rounds tricycle, tricycles important part ) good stability of this car , motor home while driving after two rounds , smooth start , but this is generally more expensive tricycle .

Folding bicycle

( 1 ) should be checked before riding the battery compartment is securely locked , the display panel of each light display is normal.
(2) When driving in rain puddles , water depth does not exceed Folding electric bikes driving under electric wheel hub cases, such as with surface water deeper than electric wheel hub , will likely make the electric wheel failure caused by water seepage .
( 3 ) the vehicle should be avoided on the air is humid , high temperature and corrosive gases , so as not to make the paint surface plating chemical corrosion of metal parts .
( 4 ) Avoid prolonged exposure to the sun and rain vehicle , so as not to damage the controller components , causing operation failure , accident .
( 5 ) electrical control structure is complex, the user should not unauthorized disassembly, repair. When the charging voltage Cargo bike such as local , easy to make charger fuse is recommended to use the AC voltage regulator.
( 6 ) when the bike feels heavier backwards and forwards will be implemented within the hub slight friction sound are normal .
( 7 ) should not be overloaded riding should not place too heavy with goods and people , in order to avoid damage to the battery and motor .
( 8 ) bicycle lubrication is an important part of bike maintenance , according to usage, deal with the front axle , rear axle , axis , flywheel , fork, shock absorbers and other parts pivot point once every six months to a year to scrub and lubrication ( recommend the use of molybdenum disulfide grease ) . The hub electric drive components have been coated with a special lubricant , users do not have to scrub their own lubrication . Found to have abnormal situation can be made to the Company's authorized service point maintenance .

Cargo bike Maintenance

1 battery can store power loss , loss of electricity means the battery charge status is not timely charge after use is likely to cause Folding electric bikes of sulfuric acid , lead sulfate crystals so attached to the battery plates , electric ion channel blockage will cause charge does not go charging , the battery capacity will decrease. Under state power loss longer idle time , the more serious battery damage. When idle battery , charge it once a month , which can extend the battery life.
2 electric tricycle battery during use to carry out regular inspection, if the electric bike to continue the mileage suddenly dropped a dozen kilometers in a short time , it is likely that there is at least one battery cell group appeared off the grid , plate softened electrode active material shedding short circuit. At this point , should go to a professional battery repair mechanism to check , repair, or with a group . .
3 Do current discharge electric bike at the start , manned , uphill , it is best to use pedal power to avoid large current discharge . Easily lead to a large -current discharge of lead sulfate crystals , to the detriment of the physical properties of the battery plates . . .
4 To control the charging time , under normal Cargo bike, the battery is charged at night , the average charging time is about 8 hours . If shallow discharge ( after charging mileage is very short ) , the battery will soon be filled , there will continue to charge overcharge phenomenon , leading to the battery dehydration , fever , reduce battery life. Therefore, in order to discharge the battery to recharge a battery optimum depth of 50 % -60 %, can be translated into practical use riding mileage, according to the actual situation of the charge necessary to avoid harmful charging. . .
5 To prevent heat exposure to electric vehicles, is prohibited in the sun exposure . High temperature environments will increase the internal pressure accumulator pressure limiting valve leaving the battery forced open automatically increase water loss is a direct consequence of the battery , and the battery will inevitably lead to excessive loss of water activity decreased battery accelerate the plate to soften the charging shell body heat, from the drum shell , deformation and other fatal injuries.

The use of electric tricycles

Electricity as an environmentally friendly, clean , energy conversion rate is important , widely used in the production and life , with the power to drive the vehicle for the application of the Folding electric bikes , promote the development of low-carbon transport sector , reduce transportation costs, energy savings , protect the environment, is an important research topic around the world , after decades of development, has been applied in electric city buses , factories electric transport vehicles , electric vehicles clean urban sanitation , engineering , tunnel, subway construction and other special vehicles many other fields. Its applicability electric tricycle , motor Cargo bike live , simple maintenance, easy maintenance and low cost advantages , flexibility to walk through the narrow road between . Electric tricycle with a reversing switch, you can easily achieve the inverted driving function, which in the narrow alley roads , lanes very useful , both with parking are very convenient. Widely used in household , urban and rural , individual lease , factory , mine , sanitation, community cleaning and other short-distance transport.

National Bicycle ownership

In recent years , China's rapid growth in car ownership in the medium-sized city to city roads run brought a lot of pressure , air pollution and other issues of urban road congestion and vehicle emissions caused by more serious. To solve these problems fundamentally , there must be a new transportation options appear. With the emergence and popularity of electric bicycles , but also the way people travel more than one option. Because electric bicycles convenient, labor-saving , easy to operate and affordable Cargo bike , it has gradually become one of the main transport urban office workers . Firstly, the development of electric vehicles in Zhengzhou introduced , and then the electric car travel for field survey and data analysis , and finally gives recommendations for the development of its problems . Electric bicycle market research surveys and Development of ownership of electric bicycles in 1998, when the Folding electric bikes annual production of about 56,000 , the production company 16 . Prior to 1998 , China's electric vehicle ownership society than 100,000 , but since then, the electric car industry is developing rapidly, with an average annual rate of 87% a big step forward. Currently about 450 million users of bicycles , bicycle ownership in the country is about 600 million . Experts predict that within the next decade , the national electric car ownership will increase to 40 million or more.

ingle wheel motorcycle

Indian company is a star there anymore, it used to be Three wheel bikes brilliant. In 1899, engineer Oscar Hyde built a motorcycle, began the history of Indian Motorcycle Manufacturing Company. Period of time, the Indian company to bright colors and excellent performance to conquer the buyer, after its owners, and some short-sighted investment behavior and frustration, in the 1950s, the end of its mission. Feature is different from BMW Harley Harley almost entirely of metal, it seems there is a electric trike feel. BMW and more like Japan is similar to the plastic housing. So you can see that many Americans from a young age until old age are driving a Harley.

Japanese Electric scooters manufacturing

Japan is undoubtedly representative of the Asian modern industry, in the motorcycle industry as well. Honda , Suzuki, Yamaha and Kawasaki of Japan 's four most famous motorcycle company . Where Honda and Yamaha started in the last century , when relying on imitation of Cargo bike of Italy , Germany, the United States started BMW and Harley . So far we are still able to see the size of many of these Honda models and even the details of the car are the same, enough real ones. The only difference is that now Yamaha has begun to look at self- creation or modification on someone else's creation, while Honda has also committed to imitate someone else's case. Began manufacturing motorcycles in Japan can be traced back early nineteenth century , but the real scale was after World War II . Since the disaster of the war, the Japanese financial fell into chaos, no order at all public transport , market need cheap and convenient Three wheel bikes transportation . In this context, a number of companies have emerged , such as Honda . Honda 1959 has started exporting to overseas motorcycle , Suzuki, Yamaha and Kawasaki followed. At that time , the Japanese domestic market competition four companies , which in turn prompted the companies in the design and manufacture of new models and do a lot of marketing , and quickly occupied the world market. And then the world's most successful British producer , but in the same position . By 1961 , Honda has become the world's largest motorcycle manufacturing company . Japanese motorcycle is characterized by appearance, driving comfort , for some details of the deal are very meticulous , thoughtful, such as lights , transmission, electric starter and overhead cam engines, motorcycles in Japan , are all standard equipment, even 125ml displacement in the car , which makes the buyer pleasantly surprised.
By 1969 , the company with a Honda CB750, broke the British manufacturers have insisted that large motorcycle market , marking the arrival of the era of Japanese motorcycles , while providing a suitable configuration for the first tranche of the motorcycle market . Japanese motorcycle in the marketing strategy is also very hard, and always will be to produce motorcycles accordance with the policies of certain countries . For example, when China 's standard 125cc or more to not on the card, Yamaha, Honda and Suzuki will actively cooperate with , and always opinionated Kawasaki always like making big row , the results also caused people think "made big row is a good car , a good car is buy Kawasaki misunderstanding " of .

Development motorcycle has Electric scooters 100 years of vicissitudes

Original motorcycle, existing in the real shape of science and technology museum in Munich, Germany, is a German Cargo bike on August 29, 1885 the world's first patented invention, a motorcycle. Limited to 100 years ago, when the gasoline engine is still in the lower childish situation, when the vehicle is still for the carriage technology manufacturing stage, the Three wheel bikes motorcycles and modern motorcycles are very different in appearance, structure and performance. Original motorcycle frame is made of wood. From the point of view wood, carpenter processed, the wheels are also made ​​of wood, covered with a metal outer wheel, the bottom is the number of frames in a square wooden frame, placed it on the engine, both sides have a wooden frame small support wheel, whose role is to prevent the dumping stationary. Therefore, this car is actually four ground.

New Cargo trikes Motorcycle

In 1953, the annual motorcycle license Folding electric bikes breakthrough 1000 . The advent of Jinggangshan brand motorcycles , marking the Chinese motorcycle industry has opened up a new era. The past 10 years , Chinese motorcycle industry develop faster. In terms of product yield, with an annual output of 49,000 from 1980 to 1990 the development of 970,000 , until today, more than a thousand million, China became the largest country in the world motorcycle production motorcycle has become a pillar industry of China's national economy - an important part of the automotive industry . Chinese motorcycle industry sales increased significantly in 2006 , a new record high . Three wheel bikes total production of motorcycles 21,443,500 , an increase over the previous year 17,767,200 3,676,300 , an increase of 20.69% ; cumulative sales of 21,266,700 , an increase over the previous year 17,745,100 3,521,700 , an increase of 19.85% . Economic efficiency index improved significantly , driven by strong sales of the rapid economic growth. In 2006, the 105 motorcycle production enterprises realized main business income of 81.629 billion yuan , an increase of 15.59% over the previous year , an increase of the amount of 11.008 billion yuan ; cumulative total profit of 2.475 billion yuan ; increase of 49.81% over the previous year , an increase of the amount of 823 million yuan . Chinese motorcycle industry after half a century of vicissitudes , forming a more perfect production, development, marketing system , a considerable part of the independent intellectual property rights , there are a number of brand-name products covered market . Especially since the reform and opening up , the rapid rise of motorcycle industry . After starting , development, integration, restructuring, trials and hardships , ups and downs of the difficult course through the Motorcycle Industry front of hard work, China has been among the world's largest producer of motorcycles .

The history of the bicycle

In 1861, France michaud of father and son, originally profession is 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) Three wheel bikes 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 electric trike difference is bigger. Truly modern form of bicycle was born in 1874. British solution during the year, a knack in bicycle on the chain and sprocket, the rotation of the rear wheel to drive the car forward. But is still a front wheel, rear wheel small, look not harmonious, unstable. In 1886, the British star, is a mechanical engineer, from mechanics, design a new style of bicycle kinematic point of view, for the bicycle mount the front fork and brakes, front and rear wheels of the same size, in order to keep balance, made the diamond frame, and steel tube also use rubber wheels for the first time. Stelios not only improved the structure of the bicycle, also changed a lot in the production of bicycle parts in machine tools, to a large number of production and application of bicycle has opened up broad prospects, so he was called the "father" of the bike. She designed the bike models and bike looks almost the same today.

Lubrication of bicycle

Bike is enormous quantity wide human machinery, electric trike structure with sliding friction and rolling friction, a little friction and line friction, fluid lubrication and boundary lubrication, oil lubrication and grease lubrication. The key to the bike movement friction is axis parts and front and rear axle, all is the use of ball bearings, with 2 calcium base grease lubrication. Every maintenance to ball and bead tank and cover with clean, to the bead with 2 calcium base grease groove, around the shaft surface smooth rounded and complete with uniform particles, special size consistent ball (beads), and then a good cover, do not make the impurities mixed with dust. Then every quarter or half a year to the lubrication oil hole () or shaft end 2-5 drops bicycle lubricating oil, or 40 ℃, the Cargo bike of 7 to 15 was/s low viscosity lubricating oil. But must be cleared before refueling refueling hole or shaft end near the dust dirt, lest cause wear and tear. When general grease lubrication can't mix oil, oil and fat in general do not mix. But on the bike is a special case, to simplify the equipment without nipple, only adding lubricating oil, to improve the lubrication. Second chain and lubrication of gear plate, here is a mixture of sliding friction and rolling friction friction, and most in boundary lubrication condition, so the friction condition is strict, must use good adhesion and lubrication oil lubrication, especially most are open, in the case of dust is more, the chain and gear plate wear serious, therefore according to the situation at any time (a quarter or half year) clean, switch to the new oil, the most to use bigger oil viscosity (10-20 was 40 ℃ viscosity/s), but in general, use and to the three axis of the same lubricating oil, it is more convenient.

Use normal riding

Use normal riding is not in need of any Folding electric bikes, but it is in the maintenance of the bicycle, one of the most important and the most basic, before riding the bike to check the cars, it is very important, also is often forgotten, so in front of the bike, remember to do the following check:
Check the riding position size: if you are not to belong to own of cycling, remember in front of the bike seat cushion will be dispatched to the appropriate level.
Check each part screw tightness: check whether the front and back and seat cushion pole quick release locking, check whether handlebar had been fixed, if other screws are loose.
Check tire: check whether the tire pressure is Three wheel bikes, enough to play to the appropriate pressure, check tire wall cracks, whether cut tire has been shallow, it must be replaced if necessary tyre.
Check the brakes: try before and after the brake, check whether the brake brake can indeed.
Before check limber wrist: stop brake, moved to the front and rear, if you have felt the shaking of clearance, said limber wrist must be readjusted.
Check transmission: try to respectively after the start variable speed before and after shifting, whether can smoothly to the gear speed, whether there will be a strange voice.

Bicycle - the first bicycle

Bicycle, Latin for Bicyoletta, is the Cargo bike of "fast" and "walk", Chinese translation "bike". In 1815, the world's first bicycle appeared in France, it has no central axis and the pedal, cyclists, like walking, reaction with the help of a pedal, the wheel rolling forward. In 1869, the French king in front on the pedal, ride up and saves energy, speed is accelerated. By 1890, a British doctor changed the solid tyre to pneumatic tyre reduced the friction with the ground, again raise the speed. With the development of science and technology, after several major reforms to evolved into the Three wheel bikes style of bicycle. In terms of the modern bicycle, there have been several major innovations, one is the added variable speed device, a multistage speed, up to 10 to 21 gear, can adjust at will, adapt to different terrain and climate conditions, to tourism has brought great convenience and competition; Second, the improvement of material, to develop in the direction of qualitative light, solid, improved the speed; Three is the improvement structure, increase the bicycle number, category, popular now have a pedal bicycle, folding bike, elliptical teeth plate of bicycle and many people travel bicycle, etc.; Four is the improvement of power, countries with low frequency has been the whole bicycle, electric control hydraulic drive bike, so that the modern means of transport. The world's advanced racing bike, only 6-9 kg each. In order to further improve the speed of racing bike, such as performance, made in Japan "aerodynamic car", in 1981 the national bicycle competition held in France, winners JiXiJie, is to use the car. The aerodynamic car has attracted worldwide attention.

Short-term regular maintenance

Short-term maintenance is often, if the Cargo bike use of the bicycle, at this stage of maintenance, is fairly simple, and the maintenance to keep your car in good condition, so must not neglect. Cleaning the car, in addition to keeping your car when new car dazzling, rust cleaning the car at the same time avoid the frame, and if you are in a heavy rain, or in the muddy riding, riding should cleaning the work as soon as possible, after washing when should pay attention to the following: if the car body of the Folding electric bikes is not much, or is more dust, can use the cloth to wipe clean, or with heavy hair brush to brush clean. Do not use water cannons to remove sludge of car body, although this method is very effective, but will likely be sewage into bearing, so will cause the damage of the bearing. Sludge of many cases in car body, the brush and soap water should be used after sludge wash, rush clean with clear water, then wipe with a cloth. After a clean car, remember to check whether there is the lacquer that bake spalling, steel frame will start to rust after peeling off of the lacquer that bake, aluminium alloy or carbon fiber and titanium frame will not rust, will only affect beautiful. In use after washing the car, remember to dry the chain, and oil. Check the brake skin: will try to keep clear of the debris on the brake, to ensure its brake force, if the wear is very serious, shall be updated. Will line pipe to oil: if the brake or speed movement, bad may be outside threats of friction is too large, will be part of the perimeter by check pipe, the paint coated butter, put back in again, if such action is still bad, consider replacement pipe outside threats. Chain: chain oil: put on oil, after about ten minutes later, will clean the oil the chain of the lateral chain as long as the part of the internal movement of oil is enough, external surplus oil will stick dust, increase clean trouble, so it's best to wipe clean. In addition, if you use the spray tank of lube oil, remember after in the oil, wipe off the drip to other parts of the oil.

Pay close attention to the important target manufacturing technology field

To boost productivity has been using the method of improve the processing speed is very concerned about manufacturing technology field and an important goal of unremitting struggle. As a Folding electric bikes one of the four advanced manufacturing technology of high speed machining technology, it has high cutting speed, feed speed and high machining accuracy, not only can increase productivity, and can significantly improve the machining accuracy and surface quality of the parts, is developed in recent years a set of high efficiency, high quality and low consumption in one of the advanced manufacturing technology. High speed machine tool is the material base, to realize high Cargo bike machining and high speed electric spindle unit is the "core" of high-speed machine tool parts, is the key to affect the processing performance. Based on the production process of motorized spindle in the actual cutting force under the action of deformation is too large, or producing self-excited vibration and the cutting machine can't meet the production requirements analysis, design of machine tool spindle component, the main focus is stiffness rather than strength. The influence of motorized spindle static characteristic parameters of the electric spindle design the main parameters of span and bearing preloaded force. Among them, changing the length of the front axle shoulder can change the spindle static characteristic; Bearing pre-tightening force is also effect on the characteristic of the spindle static. Span the distance between the front and rear bearing point called span, span different directly affect the stiffness of motorized spindle, at the same time it also affects the size of the dynamic characteristics of motorized spindle, such as natural frequency.
