Say at the beginning
In response to the topic of the new national standard, there are many controversies on the Internet, especially the three characteristics of voltage not exceeding 48V, 25 yards speed limit, and 15 yards beeping, which will "keep away" many old cars. But this industry is indeed a bit chaotic, coupled with many accidents in China, compliance is only a matter of time.
As a representative of the new first-tier cities, and the Asian Games will be ushered in this year, Hangzhou, where the author is located, has fully and strictly implemented controls on public transportation road safety. The "temporary white card" is a license plate that does not meet the standards of the national "Electric Bicycle Safety Technical Specification" and is temporarily over-used for vehicles that exceed the standard, and the original use period is until the end of last year. In the last month, according to the relevant provisions of the "Zhejiang Electric Bicycle Management Regulations", the humanized automatic extension is one year (no need to change the license plate, it can still be used until December 31, 2022), which shows that the law enforcement temperature has been achieved when the policy is landed.
After nearly three years of implementation, the new national standard has become a climate, consumers new car purchase or manufacturers to promote the old, will put the standard in the first place. The lack of a driver's license, flexible licensing, and relatively low prices have naturally become the first choice for consumers to commute in the city.
Even the main intelligent representative of the Calf, No. 9, etc. have gradually updated the new national standard version of the same model, of course, the high price is not suitable for most people. Among them, the APP is dispensable for most people, and the price is the most important, so three thousand yuan has become a very obvious watershed for placing orders.
As urban office workers, there is no need to bring people, they have become the primary consideration for fashion and appearance, and brand and lightness have become the second factors that need to be considered. Electric bicycles are moving towards the development of regularized and personalized roads, among which there are special people who are closer to the bicycle form, foldable, and long endurance, and I believe it should become another preferred choice for urban people to choose high-end cars.
Hello, ZD1
As mentioned in the preface, the author's reason for starting the Yadi ZD1 is very sufficient, and the report to the family leader was passed at once. Anyway, it is the new national standard, folding electric bicycles have high value, ultra-lightweight characteristics and traditional electric vehicles to open up obvious differences, in addition to lightweight in high-density batteries can achieve stronger endurance performance at the same price. Taking ZD1 as an example, the 48V20Ah lithium battery can achieve an endurance of about 70 kilometers, which is almost several times the price in the traditional car.
As a first-line brand, Yadi is very active in the follow-up of the new national standard, and recently the folding car has obviously exerted its strength and launched a series of new cars. It is very easy to start With Yadi, there are many offline stores, the warranty is convenient for the brand, I am too lazy to run directly online shopping, anyway, ZD1 is an integrated package, SF will directly elevator to the door.
The price of Yadi F7 (48V26Ah) with a range of more than 100 kilometers has exceeded 3,000, and I calculated that the daily use frequency is not too high for the endurance requirements, and I chose this ZD1 one by one. The ZD1 is currently available in black and white, 12Ah and 20Ah dual batteries, as well as a lighter, home version (with rear seat) ZD3 optional. The same type of folding electric bicycle for the frame material, battery capacity, safety configuration of the difference, there is a slight price difference, but the basic price range of each major factory is 2k-3k as the main battlefield.
Since the spontaneous combustion accident of the Hangzhou electric car, coupled with the Asian Games to be held, the normalization of safety and strict is imperative. In December last year, Zhejiang new car license plate must already bring the body Zhejiang product code + battery Zhejiang product code, these two codes are provided by the manufacturer or store, before the card need to provide traffic police scan code registration can enter the license process. There are also people who do not know how to get on the card, I will say more: in addition to the double code, a good ID card, invoice, certificate of conformity, in the zfb mini program: Hangzhou traffic police - vehicle management office reservation - electric bicycle on the license owner application, choose a good date and time to go, like winter can basically be booked on the same day to complete, the total process is almost 15 minutes enough. (If you do not know whether the model meets the new national standard, the online model catalog library is not updated in time, and it is not recommended to view.) The recommended method is to use the frame number query function at the bottom of the reservation page, and the detailed list after confirmation is the new national standard, and vice versa)
ZD1 is accompanied by a portable tool kit, two physical keys, and a charger. The output power of the charger is 54.6V/3A, and the actual charging performance is decent because it does not support fast charging.
The battery uses BAK brand batteries, and the quality and safety are guaranteed. The battery cell built-in 18650 lithium battery capacity of 48V20Ah, as for some people questioning the size is so small, the battery capacity is not up to standard, that is, the density factor is not considered, so this battery is far heavier than it looks. Lithium batteries are better than other batteries, especially cycles and attenuation, so the cost of the battery will be the big head, but compared with the retail batteries of other high-end smart electric bicycles, the ZD1 vehicle is estimated to be unable to change to a battery.
ZD1 comes pre-set with rear cushions, no need to buy separately, emergency use is no problem. I also watched another ZD3, that upgraded the 6061 aluminum alloy body, the motor power was reduced from 300 watts to 250 watts, the parameters are more lightweight and safety considerations, no wonder it will give ZD3 a home version. ZD1 \ ZD3 \ ZD3 home version, the difference between the three is one hundred yuan, considering that I am a personal use, so choose the cheapest ZD1 on it.
Four layers of welding, delicate paint, Logo paint, and then attached to the final coating, Yadi products in the workmanship details of the material has no choice.
Feature Highlights
Collect the pedals, fold the body, close the handle, the three-step folding method easily stores the whole car, the whole car is more compact, but the weight is still not light, and the female user wants to put a car with a smaller opening in the trunk. If the force is small and you really have to operate it alone, then remove the battery and try it again.
As a folding design, it is not just for the use of the whole vehicle into the home and the battery home to charge. I think the most meaningful thing is to do what all ordinary bicycles and electric vehicles look up to: after staying in a hotel, walk the streets and alleys to experience the life of the local people. I think this is the existence of folding cars more fragrant, and it is also the reason why I lobbied the leaders of the family to approve the speed.
Also an electric bicycle with a removable battery, the ZD1 can really be ridden alone, and entering the elevator or on the road as an ordinary bicycle can reduce a lot of unnecessary trouble. Since the battery occupies a large part of the weight of the vehicle, the weight loss can be clearly felt by riding directly after removal, so the speed-up experience is basically similar to that of bicycles with the same size of tires. It is not clear what the uncle of the traffic police will think of such a bicycle that has been on an electric vehicle license plate.
ZD1 battery lock is more common, take the design of opening and locking, the use of battery anti-theft in the city is basically enough. However, what needs to be complained about is that although there is an independent key at the ZD1 handle, it still needs to be battery powered on first. I commute to and from work short distances, don't charge the battery much, and rarely take the battery out. As a long-endurance model, it is indeed a little inconvenient to frequently insert the key to power up.
Regarding the choice of ZD1 battery dual versions (12Ah and 20Ah), the difference in battery life between the two is 30km, the weight difference is 2kg, and the price difference is 300 yuan. I think there is no need to dwell on it, large capacity not only brings long battery life, but also allows users to reduce the number of charging and reduce battery cycles, which is really meaningful. Then what should be more entangled is whether ZD1 should be upgraded to the lighter ZD3.
The highest standard of the new national standard is 400 watts, and the ZD1 is so small that it can really use a 300-watt motor. The measured electric door does not rush, it is relatively linear, but you can still feel the kind of thrust that is brisk and fierce, and you need to adapt to it from the ordinary battery car. Extreme speed measured up to about 25km/s, the author's 78kg weight in the face of the basic bridge climbing ability bar, then steep should not be insufficient power, (body light) and to consider the grip is not enough.
This car has only been on the market for less than a month, and the weather is too cold, so I have not done long endurance measurements. After the first time the battery was fully charged, it ran about less than 5km a day on weekdays, and ran away with the courier on the weekend, and the power dropped by two blocks. The power indicator is four blocks, this interval calibration is not accurate, my own gross estimate is now running 40-50km in winter, running 50-60km in summer. Referring to the official nominal endurance of 70km, there are more stringent standards (such as standard weight, flat road, low wind resistance, infrequent start and stop, etc.), and the comprehensive measurement of 20% off is already a good result. Follow-up battery performance, I will communicate with you in the comment area.
If it is said that the electric car that starts at four or five thousand is called comfort, then the comfort configuration of the ZD1 is not ambiguous at all. The height adjustment of the handle and stool can always find the best sitting posture in various height states, which is the advantage brought by the folding attribute.
The ZD1 doesn't support boosted ride mode, so there's no need to arrange narrow stools designed for long-term riding. In terms of appearance, the wide cushion (on the Pro Max size comparison chart) is indeed slightly inferior to the narrow stool, but the wrapping, shock absorption effect and sedentary characteristics of the ZD1 stool are definitely much better than the latter. It is no exaggeration to say that the ZD1 cushion is softer and more comfortable than most electric vehicles.
The fork is equipped with reflective patches on both sides, and the shock absorber travel is long enough to cushion the slope and bad road of the daily level with different impact forces. I observed that every body movement junction of the ZD1 (shock absorbers, seat cushions, faucets) was pre-lubricated to reduce wear and noise from the mechanical structure.
The tires are 14 inches and the model is a 14x2.125 anti-slip tire of the Chaoyang brand. From the picture, it can be seen that the tire pattern is smooth in the middle and the sides are very deep, which is a balance between increasing grip and drainage on rainy days. But as we all know, long endurance and grip can not be complete, Chaoyang such a design of the tire pattern, coupled with rubber materials, or more for safety considerations. If it is a thin water film, such a texture advantage is not obvious, dry or watery environment should be the advantage of this tire.
The front and rear lights are standard and turn on at the same time as the rear lights. Both front and rear are LED lighting, which is both bright and does not have to worry about power consumption.
The headlights support manual angle adjustment, the measured lighting range is moderate (about five or six meters), not the limit of the dark environment is enough to use, of course, I think riding in the city is more important after the light. In addition, when I rode at night, I found that there was an aperture behind the headlights, which enhanced the prompt from the side and could see the on of the headlights directly from the driver's seat.
Compared with the comfort configuration, seeing that the ZD1 is equipped with a huge disc brake disc front and rear, it can be seen that it has more considerations for safety. Generally, vehicles use front discs and rear drums, and changing to ZD1 has such a clean and neat braking effect, which gives me a lot of confidence. The battery plus the rear motor, basically there will be no terrible brakes with the rear wheel lifted. Measured on rainy days, the braking force is still stronger than the friction, the point brake braking process is very safe and linear, do not brake full at once.
Closing rating
Electric folding bicycles are not a new product, more expensive than ordinary bicycles, but also much cheaper than long-endurance intelligent electric vehicles, the price range can be attacked and defended. I think that choosing such a model is directly related to whether you need a unique personality, especially the need for folding storage.
At the same time, the choice of ZD1 should also make a good trade-off, not to mention that the power mode and App intelligence are not just needed for most people, but ZD1 can bring good battery life performance at the same price. Obviously, it is clear that self-needs will make the folding models represented by ZD1 more existential and selected. The old man who can't ride a bulky battery car, the mother who usually picks up the baby, and the needs of commuting and self-driving travel like me, ZD1 pokes the pain point very well.
Finally, I would like to remind you that ZD1 is still a little difficult for female users to fold and carry. If you need to be lightweight, it is better to give priority to the model of the aluminum alloy body. If you are a male user or a small number of self-driving trips within a year, you can choose the same as I chose.
