I would like to express my opinion, the electric car of the ** motorcycle you are talking about should be a pedal electric vehicle.

1: What you said about the brand is good, is the advertising effect is good or the after-sales service is good, must be differentiated, make a comparison of some electric vehicles after the image endorsement of an advertising bombardment, ** than the general electric car is more expensive than hundreds of dollars, so my personal opinion is not that the brand is good, to choose a dealer with a good reputation to sell cars, even if the brand awareness of the car he will make you satisfied.

2: The battery of the electric scooter is generally at the foot and can be removed, but you are a lady who is very heavy, I see that you will charge the whole vehicle together, about the motor, you can rest assured that the current technical motor is generally not broken, the fuselage is the rear wheel, basically will not break. Regarding the problem of brushing, you can also rest assured that now the motor is generally brushless, the brushed motor consumes a lot of power, and it is troublesome to replace the carbon brush, and the production is also troublesome, so now the manufacturer basically does not use the brushed motor, the specific simplest difference, the motor has carbon brushes and no carbon brushes.

2: There is really no way to tell you about the price, you didn't choose that style, it's hard to say, the scooter is generally around 2000 to 2800. Let me recommend a model to you, Century Lingying, a more economical and good-looking model.

The 350W motor sold on the market is generally available.

Equipped with 48V10Ah-14Ah battery** generally around 1900-2100, the stroke is about 70 miles in summer and about 40 in winter.

Equipped with 48V17AH-22AH battery** generally around 2000-2300, the stroke is about 100 miles in summer and about 60 in winter.

This can only tell you a rough idea, each place is different, the choice of battery brand is different, and there is a difference.

4: You in Guangdong to avoid the low temperature in the north affects the normal charging and discharging of the battery, as long as the battery has good after-sales service, the battery should be fine, the power of the battery will be displayed on the meter when used.

Green is best. I've ridden a total of 4 green lights, all of them were stolen, and the location of the theft was: Internet café. How to be stolen: All of them were carried directly into the pickup truck and taken away, and the chain was not prying.

Yamaha – ——— for complementary issues

1: I don't want to say about the battery, you can't go wrong with buying a good brand, of course, ** should be higher, depending on your needs. This is the same as the Nanfu battery compared with ordinary batteries, not necessarily much stronger, but you have to pay more.

2: I went to the forum in Macao to find you information, take a look.

Brushless motors do not have an adjustable option to maximize performance as far as I have seen, and the entire motor has to be replaced with a new one, for example, due to a short circuit in the coil, foreign matter entering the motor, and the motor is overloaded and overheated, resulting in magnet demagnetization.

Therefore, do not use too long screws when installing the motor, the length of the screw deep into the front cover of the motor is 2 3mm is the best, the brushless motor for the car is generally fully sealed, and the gear ratio of the motor should be appropriate, so that the motor will not overheat, my personal experience is that the tooth ratio of the brushless motor for the car is between 1:5 12 and the motor will not overheat.

Torque and speed are not the same as brushed motors, you still have to take one of the torque and speed, one index is high, then the other must be discounted.

No matter what motor do not expect the speed to be infinitely high, the torque is infinite, the two must only take one of them, for the tram, it should be able to obtain the highest speed under enough torque, but the same level of brushless and brushed motor, under the same speed, the torque of brushless is slightly higher, under the same torque, the speed is slightly higher, in short, the product of brushless torque is higher than that of brushed, this is because its efficiency is higher than that of brushed.

It doesn't matter if you use a brushless motor battery, the performance of the battery has a greater impact on the performance of the car, because the brushless system requires higher voltage, greater current and ultra-low internal resistance, and at least you must have a high-quality battery.

The coil internal resistance of the brushless motor is much smaller than that of the ordinary brushed electric motor, and the torque is also large, so the maximum working current is much larger, the battery of the tram is only 6 pieces, if the internal resistance of the battery is relatively large, and even the voltage will be low so that the motor can not work normally, but it is manifested in the car is to accelerate extremely fast, and there is a feeling of acceleration of the oil car.

Hongdu's is good**You can go to the store to see the lowest price.

Relatively large companies in the electric vehicle industry (in no particular order) ——

Xinri, Yadea, Giant, Fuji-ta (Bond), Emma, Luyuan, Little Bird, Aucma, Incley, BYV, Hongdu and so on.

The brand of electric vehicles is not very important, and the quality of the cars bought by the surviving electric car dealers is not much different, not the same good, but the same bad. Any brand of electric vehicle will have problems of one kind or another, and the scale of operation and after-sales service of local dealers are more important.

Just find a big store that has been dry for a long time and buy it.

The battery is more important, your local dealer's battery may be equipped by the manufacturer, and it is more likely that the dealer will match it himself. Try to ask him to use more mainstream big brand batteries, Tianneng, Chaowei, Panasonic and so on.

Also, ask about the warranty or replacement time. In particular, how do you calculate the time? Calculated from the date of purchase? Or is it based on the date on the battery? If it's the latter, pay attention to the date on the battery case, and ask for a new one.

The elderly use, that is, to travel, take the market to buy a vegetable or something, should not need a long driving range, with a 48V12Ah battery.

In terms of style, don't choose a style that is too big, too many decorative plastic parts, you may look good and pull it when you just bought it, and the decorative plastic parts on the periphery are easy to break, and many additional functions are easy to break, which are not guaranteed.

The development of electric vehicles in today's society is getting more and more progressive, and it is constantly strong, before buying a car, I did a lot of model brands and cost-effective comparisons of vehicles on the Internet, and finally I chose to buy Changan New Energy Benben EV pure electric car for commuting, raising it is completely stress-free, I have used it for more than a year.

The electric vehicle industry is developing very rapidly, and many people will buy electric vehicles, which are not only energy-saving but also environmentally friendly

Now there are too many brands of electric vehicles on the market, it is impossible to list them all, and the well-known ones are Oppai, Yadea, Xinri, Luyuan, etc. As for which brand of electric vehicle***, I have been mixed in the electric vehicle industry for many years, and if I understand some of the situation in this industry, I will give you a quality ranking to see.

1st place Oppai electric vehicle.

2nd place Yadea electric car.

3rd place New Day Electric Vehicle.

Fourth place Luyuan electric vehicle.

5th place Emma electric car.

6th place Tailing electric car.

7th BYVIN electric car.

8th place in the Speed Paitch electric car.

No. 9 Xinlei electric car.

10th place Bird electric car.

Several brands of electric vehicles in Taizhou are fast and strong, ** also as high as a lion, Lima, Green Horse, Green Jia, luxury and beautiful from Wuxi, light and simple from Tianjin,,, buy a car to test and compare more,,, is a donkey is a horse to ride on the yo-yo.

I can only tell you which electric car is the worst, that is, the electric car produced by the Qidefu Bicycle Factory in Wujin District, Changzhou, Jiangsu, I worked in that factory for half a year, and they were all defrauding foreign dealers of money
