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.

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 .

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 .

( 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.

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.

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.

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.

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.

Four national standards for electric bicycle is the most main

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.

Cycling (cycling) is a bike for tool match speed cycling sports

Cycling (cycling) is a bike for tool match speed cycling sports. The first Olympic Games in 1896 is listed as official event. International cycling union was founded in 1900, since then have been for a world championship, held once a year), the world peace cycling (around Berlin, Warsaw, Prague, 1 week, more than 2000 km long), tour (around 1 week in France 3966 km of days). Before and Cargo bike cycling in China in 1913 by pass in Europe. When the bike is mainly used as transportation. Pan Deming riding a bicycle to travel around the world in 1930, the Vietnam, Cambodia, Thailand, Australia, Indonesia, Singapore and Three wheel bikes, Cuba, the United States, Canada, Sweden and so on more than 40 countries and regions, more than seven years to return to China. 1940 years later, China held a different in track and field in the form of small and medium-sized bicycle race. Held in Shanghai in 1947 China national exhibition games for the first time. After the establishment of the People's Republic of China, the cycling got comprehensive and rapid development. In 2002, China's first held tour DE qinghai lake, 2007 have held six sessions.

The bicycle is used by a lot of in the city

In the city is widely used, not only in the surrounding area also has a broad market space for development. 1 the villages and towns with the main characteristic of electric bicycles 1.1 requirements characteristics compared with cities, villages and Three wheel bikes with electric bicycle main show the following characteristics: (1) rural environment relatively sparsely populated, charging inconvenience, of vehicle travel demand is high; (2), bumpy road traffic sex difference; (3) not only travel tools, often have cargo needs; (4) maintenance inconvenience, higher requirements for durability; (5) the user to the price factor is more sensitive for the Cargo bike residents. 1.2 improvement direction by the above characteristics and differences in rural environment related security policy it is not hard to see, electric bicycle function requirements for rural areas closer to the motorcycle, so the improvement should be considered as the following aspects: (1) expand the battery capacity, to increase the range and response charging and maintenance inconvenience; (2) increase the wheel diameter and improve the axis, in response to complex road conditions; (3) reduce weight to increase the load capacity; (4) on the premise of cost allows provide shock absorption function; (5) simple structure is easy to repair. 1.3 design scheme selection at present mainstream electric car exterior design thought was based on a motorcycle and bicycle.
