The battery is the most important, then the motor, and the one without brush is the best. The price of bicycle styles is generally around 1800. The cheapest motorcycle model costs more than two thousand yuan. Different manufacturers have different prices. If you want to buy it, buy a famous brand. Well-known manufacturers have guaranteed quality and good after-sales service. Don't feel bad about that few hundred dollars when you buy it. If you buy an electric car from a famous brand or a small manufacturer, the batteries and motors they use are definitely not good and their service life is short, then you spend more money. Think carefully before buying, read more books and ask more questions, and don't make decisions easily. I wish you can buy a desirable electric car.

Style selection

1. There are three main driving modes for electric bicycles: one is wheel drive, the other is center drive and the other is suspension drive. The electric bicycles in the market are mainly driven by wheel hub, which is better than rear wheel drive, but the front wheel drive performance is relatively poor. 2. Considering the balance of the whole vehicle and the convenience of getting on and off, it is best to put the battery in the inclined tube or vertical tube of the frame, and the configured batteries are basically economical lead-acid batteries. At present, most electric bicycles use 36V 12AH lead-acid batteries; Because the battery with 24V 12AH has a short continuous mileage, consumers have fewer choices.

Functional style selection

1, standard type: the motor power of this kind of electric vehicle is generally 150W, which is characterized by simple and smooth appearance, continuous driving mileage of 40km~50km, simple operation, moderate price, and the price is about 2,000 ~ 2,600 yuan, which is more suitable for users with long commuting distance and certain mobility in work and life. 2. Multifunctional type: This type of electric vehicle is generally equipped with front fork shock absorber, saddle shock absorber, headlight, electric horn, etc. On the basis of standard types. It is characterized by more functions, more comfortable riding and more convenient use at night. The price is generally around 2500 ~3000 yuan. 3. Luxury: This kind of electric car is characterized by novel and luxurious modeling and more complete functions. Usually, an instrument panel is added to the handlebar to display the speed, mileage, voltage and power, and some of them are also equipped with turn signals, language prompts, rearview mirrors, toolboxes and safety nets. The price is generally around 3000 ~3400 yuan.

Specification selection

The general number of electric bicycles is 6 10 mm. At present, manufacturers have designed and manufactured 660mm or 560mm electric bicycles to meet the needs of consumers at different levels.

Brand selection

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. Consumers can pay attention to the "reputation mark" issued by China Bicycle Association on electric bicycles.

1, according to my actual needs and preferences, choose the appropriate specifications, styles and colors.

2. First, choose the appearance quality of the vehicle, mainly to see whether the trademarks and decals are in good condition, and whether the surface quality of paint parts, electroplated parts, plastic parts and aluminum alloy parts is satisfactory. 3. Check the quality of vehicle assembly, which should be as follows: a. All kinds of screws are fastened in place without looseness. B handlebars, wheels, chains, cranks and pedals should be flexible to operate, and the rim should have a circumferential speed and a small amount of circumferential runout. C handlebars, car seats, clay tablets, clothes hangers and brackets shall be installed vertically or symmetrically without obvious deviation. D moving parts (such as chains, cranks, wheels, etc.). ) and fixing parts (such as chain cover, clay board, etc.). ) Do not rub.

3. Try the switch key and battery lock, which should be safe, reliable and easy to use. It is most convenient to use a key for electric door locks, battery locks and toolbox locks.

4, turn on the switch, turn the speed change handle, check the stepless speed change and braking (braking) power failure and braking effect, check whether the motor runs smoothly and the sound is normal.
