I want to buy a navigator I m a battery car! ）

You can try to use the navigation function of the mobile phone, Google Maps or maps are not bad, depending on the mobile phone operating system, there are many other navigation software, the advantage of this is that you do not need to spend extra money, because you want to use the mobile phone anyway, the disadvantage is that it may consume some data, and the mobile phone investment is higher, but it will not produce waste.

I don't think many couriers use navigators, right? It is not to run the whole country, no matter how big cities are, such as Shanghai, as long as you run every day, you will know the road there in less than half a year, the navigator is not necessarily very practical, there are still some errors, the road is on the mouth, and it is better to ask more than a dead map. If you have to buy it, buy a good one, car GPS, maybe you can use it by driving yourself in the future.

This is still based on individual needs. Portable and vehicle-mounted models each have their own advantages. Portable is easy to carry, ** cheap, but generally adsorbed on the money windshield with a bracket, it needs to be charged frequently, and the function is relatively simple, and the screen size is generally about 5 inches.

The vehicle-mounted type is now basically a special car type, which will not change the appearance of the center console, and can be integrated with the vehicle without changing the line, generally containing ***, GPS navigation, Bluetooth hands-free ** and other functions, directly powered by the original car, and the screen size is about 7 inches. Navigation maps generally contain fixed-point cameras and speed limit signs, but they are all realized through positioning, and do not have the function of mobile speed measurement. There are some portable models that can be equipped with hardware dongle detectors.

You can go to the windmill shadow network and search for it, this kind of stuff is quite comprehensive there.

It is recommended that you sell electric vehicles that are both petrol and electricity.

If the voltage is high, you should run faster, the strength should be greater, and if the number A is larger, you should run farther.

In fact, the quality of the three brands of cars you said is good, if you want to run far, or choose a car equipped with a 48V20AH battery, which is more practical! But in these three brands of cars, it is estimated that there is absolutely no within 2,000 yuan, and at least about 2,600 yuan! If you choose a simple model, it is best to choose a 48v12ah battery configuration, but don't buy the "load king" car, it is easy to break the strip.

The front brakes don't work well yet!

In fact, there are not many electric cars, there are 45 volts, it is 3 batteries, 60 volts of 4 batteries, the general express delivery with 60 volts, can run 40 kilometers, the new ones do not need 2000 yuan, too good is not necessary, and it is too easy for thieves to see, hehe, the general battery life is 1 year, if you want to save a little, just buy a 2-hand frame, 2-hand frame 700 is very good, buy a new battery, 60 volts, 4 is 400 is enough.

Assembling 2000 by yourself is enough for the motor 800W, 5 24A batteries, to use a 60V charger, the speed is definitely between 40 and 50, for the sake of safety, the common choice of batteries is natural, super for waiting to buy an electric car, just 1 on the line. I will come to change the motor by myself, and I won't ask someone to help because the speed of the car I bought is limited, and this is the only way.

Giant is good, it is produced in Jining, and now the normal price of electric vehicles is a little more than 1600, and we use Shengyang electric vehicles, which are produced in Jiangsu.

If you buy that kind of large battery car, you can put two sets of batteries.

Electric bicycles are an energy-saving and environmentally friendly means of transportation, and they are now very common in use. In terms of its specific management, listing management has been implemented in some cities, but most areas do not require listing, which depends on whether your area requires listing management. For details, please consult the local public security traffic police department.

Even if it's a card, it will be very cheap, and it's a big deal to pay dozens of yuan a year. Because the current car registration is only more than 100 yuan. If your area requires listing management, and you do not register as required, then of course the traffic police will be in charge.

I don't know, ask the traffic police, it's safer.

Electric cars, electric cars are convenient and cheap.
