electric folding bikes inspection methods

A visual inspection: the appearance of deformation, breakage, leakage, contamination and other tests.
Two voltage measurements: total voltage measured first, and then measuring the single cell voltage, and one by one to check whether the Folding electric bikes connection is intact normal.
3 Battery check valve Ministry: Take the lid open above to see if the safety valve is surrounded acid and other Electric folding bikes, with hands open safety valve, check for adhesions, loose or damaged and so on.
4 Battery internal checks: Check the main items: (1) Electrolyte: visual humidity inside the battery electrolyte, strips of wood and other heuristics should be moist feeling. (2) Check the battery voltage of a single cell determination "short" and "circuit breakers" Fault: single cell voltage measuring method is to measure the contact with the battery wire bus bar.
5 Battery tightness tests: Pressure test device modified sphygmomanometer, inflatable battery, the pressure in the 30-40Kpa, observe the pressure gauge is stable, can also be placed in the water to check the battery.
6 Capacity Check (by JB/T10262-2001 standard): The battery connection is fully inflated discharge, the discharge current 5A.

folding electric tricycle whether on the subway ?

"Why another city subway can carry folding electric bikes, Xi'an Metro does not allow ? "Recently, there are people on the microblogging asks . In this regard , Xi'an Metro said that if put into bags in the folding bike (can not use plastic wrap ) , are allowed to bring cars.
This is the name of the people on the microblogging said he had to call the customer service telephone consultation Xi'an Metro , the platform still ask , have been allowed to bring folding electric tricycle reply subway , which makes him very puzzled , " Europe , the United States , bicycles You can enter rail transportation . domestic Nanjing, Guangzhou , folding bikes can also be brought into the subway, why not allow Xi'an happens . " Some people think that some of the metro station take bus is not convenient , there are also individual public bicycle subway station , if we carry on a portable bike subway, can effectively solve the " last mile" access needs. In this regard, Xi'an subway operator Branch staff said , clearly states that " Xi'an urban rail traffic regulations " prohibit the carrying bicycles and other modes of transport stop, ride . " Prior to its enactment , the experts there was intense discussion , they think themselves sharp Electric Folding Bikes parts are more relatively more passengers on the subway , the subway if you let the bike , do not disturb other car that is also easy to scratch ," which The staff member said . "If the folding bikes are allowed on the bags in the car ," Metro staff reminded , if only wrapped with plastic bags are not allowed to take the subway.

Folding electric trikes tire must be noted that the local

folding electric bikes tire has a characteristic , if one did not succeed, then this tire useless. There are two reasons for the failure :
1 tire sealant that is dry , apply patch . Gum solvent volatilization process, while discouraging between the tire and the tire pieces forming gas channel . If you are too impatient , apply patch Patch Kit can be found on the tire slide , this is basically a tire on the death penalty .
2 slices between tire and tire has not expelled air. Similarly discouraged between tire and tire pieces forming gas channel .
To draw attention to the following points when the bicycle tire :
1 Carefully break point to find . In only about as wild as the first post link , listen with our ears . The best preparation for a crayon , marked the first break point and then started working .
2 Carefully break point play rough around . In particular, if the break point in the tube near the parting line together , but be careful of the tube mold lines polished .
3 glue must break point as the center , a radius of about 15mm, first draw a circle with glue , and then go on break point average on glue. Reason: In terms of the first break point of the plastic, then gradually out of the glue , because the glue is not easy to see a visual break point , it is likely to cause the tire , tire breaking point is not the middle piece , representing the probability of tire failure high .
4 must wait after applying the glue to dry on the surface , appears to be gray instead of shiny shiny , in order to apply patch .
5 After the tire chip , hard to find a flat place, spread on top of the tire , tools and gradually tapped out by the broken hole to determine the expelled air.
6 Carefully check the tire , be sure to find the culprit Sapporo tires . If necessary, bring along a needle-nose pliers to pull the nail prepare .
7 Replace the tube to smooth , to avoid tire inner tubes and wheels rolling has been broken .

Routine maintenance folding bike tires

Looking at the current all types of folding electric bikes, inflatable tires are normally used as an inflatable tires and elastic rubber tires, which not only has a strong and flexible, and can ease the process of moving part of the absorption due to the uneven bumpy road the shock and vibration, so that the car can effectively running smoothly.
First, we should always check the tire pressure is normal, if found pressure is too low, then there might have been a partial outer casing scratches, stabbed problems to be detected promptly repaired.
For the tire wear to be extra attention because of poor road conditions when traveling, the wear on the tires is very large, especially outside of the tread wear lines, between the lines remain embedded in the sand, hard, can cause direct damage to the tire rubber surface.

Folding bicycle freewheel

Within fixed flywheel screwing right rear axle , and the chain to maintain the same plane and connected by a chain and sprocket drive system constituting the electric folding bicycles . From the structure can be divided into single-stage and multi -stage flywheel flywheel two categories. Flywheel also known as single-stage single- piece freewheel sprocket , mainly by the coat, flat block and core , extremely heavy , extremely heavy springs , washers, wire block a few balls and other parts.
Its single stage freewheel works: When moving a step forward foot is chain driven flywheel rotates forward , then the flywheel teeth and extremely heavy phase containing flywheel rotation force transmitted through extremely heavy slug , slug driven rear axle and rear wheel bicycle on forward . When you stop pedaling action pedals , chain and coat do not rotate , but the rear-wheel drive is still under the effect of inertia and extremely heavy slug forward rotation , then the flywheel relative sliding in the tooth , thus compressing the core to the core the sub- notch , extremely heavy and extremely heavy compressed spring . When extremely heavy gear tooth tip slid inside the top of the flywheel , the most extremely heavy spring is compressed , and then slide forward a little bit , extremely heavy shells to be extremely heavy spring tooth root , the issue " blah" sound. Core rotating faster, jin soon slide the flywheel teeth in each issue "blah " sound. To components. Multi-level flywheel is at the flywheel when the single-stage reverse foot pedal action , jackets reverse rotation , slide will accelerate extremely heavy , so "blah" sound more rapid. A multi-stage flywheel weight based on the bicycle speed change device , a few slices of sprockets increase , combined with the sprocket shaft, the composition of the various transmission ratio, thereby changing the speed of the bicycle .

Folding bike pedal parts

Pedal components: left pedal crank member mounted on the axis member, the translational force is a rotational force into the device, when riding a Electric Folding Bikes, the pedal force is transmitted to the first pedal member, and is rotated by the pedal shaft crank axis, the chain flywheel, rotate the rear wheel, so that the bicycle forward. Therefore, the structure and size of the pedal part is appropriate, will directly affect the rider's position is appropriate to put the foot, bicycle drive can proceed smoothly.
Foot: can be divided into integral and modular foot pedal. No matter what style of foot pedal surface must have to be safe and reliable, has a non-slip performance, you can use a rubber, plastic or metal materials. Pedal must be flexible rotation.

Folding bicycle fork parts

Bicycle fork member is in the front portion of the structure, with its upper end part connected to the steering wheel, the front frame member and the tube, with the lower end of the axle member, a guide system consisting of a bicycle. Turn the handlebar and fork, you can change the direction of the front wheels, has played a guiding role of the folding bikes electric. In addition, you can also play the role of controlling a bicycle traveling. The forces of the front fork member is cantilever nature of the fork member must have sufficient strength and other properties.

Wheel sizes to choose from folding bike

folding electric bikes mainstream products are mainly 16-inch and 20-inch (There are other 12 inch, 14 inch, 18 inch), of course, if you have special needs also have 26-inch products. Generally, 16-inch and smaller products folded smaller collections in favor of transport, more suitable for short-distance riding. If you often have to ride long way, we must consider 20-inch products, not only ride comfort, better than the 16-inch and frame strength will be higher, faster. Of course, the best selection of products with a long-distance riding transmission.

Points to buy electric vehicles

1 Check the appearance, watching paint, plating surface is intact.
2 actual operation according to the instructions again, check the working condition of the vehicle. Speed ​​the transition should be smooth, without the impact of the initial sense of rotation of the folding electric bikes wheel should be the spirit
Live, no sense Zhizhong, wheels turning soft voice, no noise, brakes should be moderately elastic, reliable braking.
3 Also check that the car should have auxiliary functions (such as battery indicator, speed, mileage display, etc.) is in a normal state.
4 Truck of matching accessories, chargers, certificate, manual, warranty card is complete.

Folding bicycles must buy knowledge

Height, under normal circumstances, the height at 160mm or less, choose 12-16 inch models; 170mm or more select 18-inch models; any car can be between 160-170mm.
Weight, weighing 70 kg or less can choose any car, but weighing 70 kg or more, try not to choose 12 and 14-inch models.
Typically one-way ride distance, one-way ride within a distance of five kilometers, any car can be;, but not more than 5 km for single-speed vehicles; over 10 kilometers, try to choose a transmission speed of the vehicle.
Residence or unit where the floor, if the daily need Palou span the four floors above the electric folding bicycles, it is recommended to select relatively light weight of the car.
How often need to bring the car to take public transport, often with a car if you need to take public transport, then try to select 16-inch or less, lighter models.
Cycling habits, if like 15km / h above the speed, the proposed purchase of more than 16 inches of fast, models with variable speed, 10km / h or so slow ride, single-speed models more than enough.

electric folding bikes operating points

To ride this Folding electric bikes, you first need to sit up, put his hand on the helm side of the trunk, finger accelerator and brake, and just feet firmly on the footrest. Bicycle seat designs and specifications are humane, without the rider pedaling hard, save a lot of energy. Front looks like a rider sitting on a bar stool in Gao, a speed of 17 km of the speed, the legs do not move like a man floating by, an eye-opener.

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.

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.

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.

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.

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 .
