In urban life, driving is too congested, subways are too crowded, public transportation is too slow, motorcycles are not allowed, shared bicycles are not available, and it is very difficult to ride. Electric bicycles can meet the daily commuting needs of most people. To this end, we start fromEndurance, performance, comfortThree dimensions to help you choose a reliable and easy-to-use electric scooter.
Before choosing a car this time, I will give you two tips for choosing a car.
First, only chooseMeet the new national standardRequirement, a vehicle that can be registered normally. Each major city has its own catalog of electric vehicles, and only the models in the catalog can be driven on the road.
At the end of the film, we have also prepared how to obtain the catalogs in various regions. If your area has not clearly restricted non-compliant electric bicycles, we also recommend that you directly choose the new national standard models to ensure higher safety and longer service life.
Second, in addition to prioritizing lead-acid batteries for 1,000 yuan models, models equipped with lithium batteries will be prioritized starting at 2,000 yuan; lithium batteries have a long cycle life and higher energy density. Under the same range of 40 kilometers, lithium batteries are generally only available. It weighs more than ten kilograms, and the lead-acid battery is at least thirty or forty kilograms.
This time we choose the 2,000 yuan gear (1499~2499) with the largest sales in the market. In this price range, you can see models with simple structures, as well as products that stand on the threshold of intelligence and bring some convenient functions. .
Model introduction
This time we bought 5 cars with relatively basic functions, including Yadi, which has the largest market share in China, and Mavericks, which are loved by young people. Some smart functions can be realized, one is the most expensive No. 9, and the other is relatively cheap Hello. But the most special thing is that it has to be Sitino, with a large 24ah battery, a battery life of 90 kilometers, and an ultra-low price of 1499 yuan.
Endurance: reverse and reverse again
In order to restore the true endurance of the five vehicles as much as possible, we recruited five “riders” to ride at the fastest speed on a fixed loop of 8 kilometers under the premise of safety, and exchange drivers every half circle. Possibly control variables.
As a result, the Mavericks barely ran 40.2 kilometers, Haro’s performance was relatively reasonable, and the final score was 47.2 kilometers. At this time, No. 9 still had room to reach 50 kilometers, and Yadi scored 58.4 kilometers, which is not a small one. Surprise.
And the most effective program is to fight for the superb bike. The morning test easily ran 48 kilometers, and it was still fully charged. In the afternoon, we prepared an exclusive test for it, and a copy of the third ring road was opened. The first grid is extremely powerful, and the last three grids are smashed. In the end, Yadi, which is half the battery, ran 5.4 kilometers less, with a total score of 53 kilometers.
Considering that the difference between 53 kilometers and the nominal is too large, we asked a colleague who weighed a little bit to conduct a retest, and this time it didn’t even reach 50 kilometers. We asked the customer service and learned that the 90 and 95 kilometers are the manufacturer’s test data, which include pedal-assisted endurance tests.
A battery with twice the capacity and light weight to a rudimentary electric car can only run out of a range that is not much different from the competition. To say that it is too inefficient, we think it’s better to be simpler, it may beFalse mark the battery. Then we emptied the batteries of all five cars and performed a charging test on them.
Charging test: unexpected
The test method is very simple. Use two smart sockets to record the power consumption of the charger. The 12ah battery should be at least 0.58 kWh when the battery is fully charged, and the 24ah battery should not be less than 1.16 kWh.
As a result, the four mediocre models all exceeded 0.65 kilowatt-hours of electricity, which met or exceeded their own nominal capacity. The god car only uses 1.1 kWh of electricity, even if the loss during the charging process is not considered, it does not reach the nominal capacity of 1.16 kWh. Converted, the true capacity of the Shenche battery is around 20ah.
The sacred car has a false standard, but the battery is still larger than the other four cars. The larger battery has not been replaced with the advantage of the range, not to mention whether the quality of the brand-name battery itself is not problematic. The motor, main control, and Tires may have hidden dangers in all aspects.
Performance: Dangerous action, please do not imitate
In terms of motors, the Mavericks and No. 9 are equipped with 400w motors, and the remaining three models, including the god car, are all 350w.
As the new national standard requires electric vehicles to be no faster than 25km/h, there is not much difference in the speed of everyone. The measured four vehicles can basically only run to 23, 24Km/h. Only the sacred car, without any software cracking, can run to a speed of 33km per hour.
But this does not mean that the performance of the sacred car is good. In our 20-meter acceleration test, it is the slowest of the five cars. What’s more terrible is that when the sacred car was first sentNo brakes at all, If it was on the road for a test drive at that time, the consequences would be very dangerous.
How about the final braking performance of the Shenche after I have tuned it several times with a master at my own expense? Drive at full speed 33km/h, stop at 11.7 meters; control the speed at 23km/h, stop at 8 meters. Compared with it, the Yadi with 3.3-meter stop is considered to be a good result, and the best-performing No. 9 is 1.9-meter stop.
To briefly summarize the performance part, Yadi is the fastest to accelerate and No. 9 is the best brake. Hello and Mavericks are relatively balanced. As for the sacred car, it does not matter.
Comfortable: sitting, riding, using, stopping, all have to be comfortable
What kind of electric car is comfortable? In order to answer this question, except for the magic car without brakes, we rode the remaining four models for a week and the accumulated mileage exceeded 500 kilometers. In the end, we are more willing to ride, it is the Mavericks and the 9th.
Yadee’s point of deduction is that the direction is too flexible, and the process of going straightControlling the direction is more laborious; The shock absorption is hard, and the consistency of the front and rear shock absorption is not good.
Hello is too flexible in the same direction, and the hardness of the front and rear shock absorbers is also significantly different. The difference is that its seat is not very comfortable, and the sides cannot effectively wrap the pubic bone.
And as a so-called smart electric car, itselfOnly 2g network, Resulting in its function is very simple. Record driving trajectory needs helpcell phone, When you lend your car to someone to ride, there will be no track of the car on your phone. More deadly, itYes and only mobile appThis kind of unlocking method, if the phone cannot be unlocked when there is no internet, it will not be unlocked.
Because the Mavericks we bought are the lowest equipped, there are no smart features. Its advantage is that the seat is soft and spacious, and the shock absorption is more comfortable for filtering small bumps. The disadvantage is that the consistency of front and rear shock absorption is slightly different. When faced with big bumps such as speed bumps, the rebound of the rear shock is not fast enough. What bothers us is a small problem, its battery compartment cover always does not rebound, every time you have to pull it by hand.
The number 9 is relativelySuitable for riding alone, Shock absorption is crisp and neat, steering is stable and comfortable, vehicle trajectory is recorded in real time, people and vehicles are separated for three seconds, and the vehicle is automatically locked. The intelligent functions are comprehensive and non-feeling. But it is not perfect. Firstly, it is 500 expensive. Secondly, its mobile phone key has failed once. Fortunately, it provides three unlocking methods, which is much better than Hello.
What’s really annoying is that in addition to the speakers, itOnly one button, All functions must be realized with this one button, which looks simple and symmetrical, but in fact the comfortable surface brings more discomfort.
Summarize
Among the 5 models reviewed this time, the No. 9 a35 is our most recommended. Its overall performance is the most balanced, and its smart functions can also be the icing on the cake. The overall battery life is 10 kilometers faster than the Mavericks. For the kilometer distance, the advantage of No. 9 is not that it can barely be charged once every two days, but in the winter of Beijing, it can be more confident to be charged once a day.
The second recommendation is Yadi Xiaojinguo. Its battery life is nearly half longer than that of the Mavericks, almost reaching the nominal level of many 3,000 yuan models. At least there are no major errors in other aspects, and it is most suitable for users who pursue cost-effectiveness.
As for the miscellaneous brand products such as Shenche, no matter how beautiful or luxurious a certain parameter of it is, it is at most a “Faraxiali”. We were riding this bike on the third day, because its seat screws were not tightened, and we were almost taken away by a wave.
What we don’t understand most is that businesses have the energy to break the speed limit, but they don’t want to spend even a little time considering the most basic braking performance. They don’t care about the safety of consumers at all, let alone talk about after-sales and warranty. Kind of service.
Compared with big brands, small factories with different brands often cost much more to make the same products due to their differences in scale. However, the current situation is that they are generally cheaper. Where does the profit come from? The motor, the frame, the main control system, and even the battery itself.
We have communicated several times with engineers from some electric vehicle companies. They said that for the safety of lithium batteries, major brands have prepared more than a dozen safety measures in all aspects of batteries, batteries, motors, wiring harnesses, bms systems, etc., except for experiments. In extreme experiments in the laboratory, deflagration and other problems rarely occur in daily life.
However, in real life, there are several news about fires caused by battery charging almost every month, and there are even cases of sudden fires during riding. Just a few months ago in Hangzhou, a pair of women’s batteries caught fire when they were riding bicycles. Ignoring that he was on fire, the father rushed to use a fire extinguisher to put his daughter out. In the end, more than 90% of the father’s body was burned, and his daughter was given a critical illness notice three times. For this little girl, her future and her entire life have changed because of this.
We hereby advise everyone not to buy this kind of electric car, nor to buy a brand-name lithium battery. It’s safer to choose a model with a large-brand lead-acid battery for a car with a price of around 1,000 yuan.
