What are the maintenance methods and skills of electric bicycles?

Nowadays, many people have an electric bicycle. Because it is convenient to ride, it may be used frequently. So how to repair it if it is broken during use? The following is the method I sorted out for you to repair the electric bicycle, hoping to help you.

Maintenance method of electric bicycle 1. Chain: Check the tightness of the chain before using the electric bicycle. When the chain is too tight, it is laborious to ride, and when it is too loose, it is easy to shake and rub other parts. The chain sag is 1-2mm, which can be adjusted properly when riding without pedals.

2. Tire: Insufficient tire pressure of electric bicycle will increase the friction between tire and road surface, thus shortening continuous driving mileage; It will also reduce the flexibility of handlebar rotation and affect the comfort and safety of riding. When the air pressure is insufficient, the air pressure should be replenished in time.

3. Handle bar: When the handle bar turns inflexible, stuck, stiff or too tight, it should be lubricated or adjusted in time. Butter, calcium-based or lithium-based grease is generally used for lubrication; When adjusting, first loosen the lock nut of the front fork, turn the gear on the front fork, and lock the lock nut of the front fork when the rotation flexibility of the handlebar meets the requirements.

4. Lighting: Check lighting, speakers, etc. Before using electric bicycles, especially when traveling at night. Headlights should be on, and the light beam generally falls within 5- 10 meters in front of the front of the car; The flashing frequency of the lamp is 75-80 times/minute; The instrument display should be normal.

5. Battery capacity: Check the battery capacity of the electric vehicle before going out, and judge whether the battery capacity is sufficient according to the mileage. If the power is insufficient, it should be supplemented by human riding to avoid battery undervoltage.

6. Motor: Check the working condition of the motor before going out. Start the motor and adjust its speed to observe and listen to the operation of the motor. If there is any abnormality, it should be repaired in time.

Electric bicycle 1 daily maintenance points. Before using the electric bicycle, you should pay attention to check whether it is in good condition, such as whether the tire pressure is sufficient, whether the front and rear brakes are sensitive, whether the whole vehicle has abnormal sound, whether the screws are loose and whether the battery is fully charged.

2. When the vehicle is just starting, it should be accelerated slowly to avoid sudden acceleration and damage to parts. In order to prolong the service life of the battery and motor, the vehicle should use pedal power or push hard when starting and climbing.

3. On the premise of ensuring safety, try to reduce frequent braking and starting during driving to save electricity. When braking while driving, you should loosen the speed control handle to avoid damaging the motor and other parts (new cars now generally have automatic power-off devices, but it is better to pay attention). Turn off the power supply when you get off the bus to prevent the car from starting suddenly when you turn the speed control handle unintentionally and causing an accident.

4. Pay attention when charging, and don't use other brands of chargers. Each brand of charger matches the performance of the battery. Only a special charger can achieve the best charging effect.

5. The charger contains high voltage lines. Please do not disassemble it without authorization. When charging, the charger should not be covered with anything, but should be placed in a ventilated place. At the same time, pay attention to prevent liquid and metal particles from entering the charger to prevent them from falling and hitting, so as to avoid damage.

6, electric bicycle parts appear loose screws, etc. , to adjust the fastening in time. If you find something abnormal during riding and you can't repair it yourself, you should find a repair shop to repair it in time.

7. When charging the battery, you should use a matching charger or a charger designated by the manufacturer, and don't mix them; When charging, the battery and charger should be placed in a ventilated and cool place, firmly away from flammable and explosive materials, and avoid high temperature, humidity and water shower. It is forbidden to cover it with articles to prevent infants from touching it. After charging, disconnect the power grid first, and then disconnect the charger from the battery. Lead-acid batteries usually take 6-8 hours to charge.

8. When the battery reaches the undervoltage state, stop using it and charge it as soon as possible. It is forbidden to use the rebound voltage of the battery, and it is forbidden to deeply discharge and overdischarge the battery. It is best to use it while filling it, so that it is always in a rich state. It is recommended to charge at least once a day.

9. The battery should be placed in a cool place with moderate air humidity, and the battery should be placed upright; Long-term storage should be fully charged and charged regularly, usually once a month. Lead-acid batteries can be stored for a long time. Adding a few drops of distilled water can offset the evaporation of water and reduce the vulcanization of the plates.

Teach you how to buy an electric bike. 1. Choose brand and after-sales service reputation.

Brand is a symbol of quality, and the quality level of different brands is uneven. Consumers must choose brands with reliable quality, low repair rate, good after-sales service and high reputation that have been tested by authoritative departments.

Second, the choice of electric vehicle style and configuration

Optional configuration: The four components of an electric vehicle are: motor, battery, controller and charger.

1, the driving mode should be considered comprehensively, and the mode with low loss, low energy consumption and high efficiency should be selected; There are three main types of motors: brushed high-speed motors, brushed low-speed motors and brushless motors. High-speed motor has high efficiency, high power and strong climbing ability, which is suitable for long-distance driving. Brushed low-speed motor has low efficiency, large power consumption and short driving range. This motor is suitable for consumers with flat roads, light riding and climbing. Brushless motor needs current commutation, the controller is easy to burn out, and the reliability is transferred from the inside of the motor to the controller. The price of high-speed motor is nearly double that of low-speed motor.

2. Batteries are divided into 36V, 48V and 64V according to voltage and 10Ah, 12Ah, 14Ah and 20Ah according to capacity. According to types: lead acid, nickel hydrogen, lithium battery. A battery is a combination of voltage and capacity. Some cars are equipped with 36V 12Ah, some cars are equipped with 48V 12Ah or 20Ah, and some cars are equipped with 64v20Ah. There are great differences in capacity, mileage and price between the two. The purpose of buying an electric bicycle must be clear: as a means of transportation to and from work, don't be too demanding.

3. Chargers and controllers are also quite different in internal quality, price and performance. The charger is not original. It must be good. Pay attention when buying.

Third, the choice of functional style.

At present, electric bicycles are generally divided into three types: standard type, multifunctional type and luxury type, which can be selected according to actual needs and economic conditions.

Fourth, the main points of choosing at the car purchase site

1, according to my needs and preferences, buy the appropriate specifications, styles and colors;

2. Set the parking bracket, check the appearance to see whether the paint is peeling off, whether the electroplating is bright, and whether the seat cushion, double-clip, tread, steel ring, handle and basket are in good condition;

3, under the guidance of the seller, according to the instructions of the actual operation again. Try the on-off key and battery lock, which are safe, reliable and easy to use. If the battery button is tight, gently press the battery with the other hand when switching. Turn on the switch, turn the speed change handle, check the stepless speed change effect and braking effect, and check whether the motor running sound is stable and normal. The wheel rotation should be flexible, without hysteresis, the electric quantity display of the controller is normal, the speed change transition is smooth, there is no impact when starting, the wheel rotation sound is soft and there is no abnormal impact sound;

4. For multifunctional and luxurious electric vehicles, check whether the functions are in good condition;

5. The purchased accessories, invoices, chargers, certificates, manuals, three-guarantee cards, etc. Attached to the vehicle shall be collected and properly kept. Some manufacturers have established user file systems. Please file according to the instructions in order to enjoy after-sales service.

Fifth, after-sales service should not be sloppy.
