Guangzhou's new regulations on the registration of electric bicycles will be implemented soon, and electric bicycles that meet the relevant conditions will be registered and managed. To be licensed, the first thing must be a new national standard electric bicycle. However, in the past few days, Nandu reporters have secretly visited the chaos of electric vehicle modification and found that many electric vehicle stores provide electric vehicle modification services, saying that they can "solve the soft solution" and "hard solution" to the new national standard electric vehicle. In the face of the new regulations for electric bicycles in Guangzhou, some offline electric vehicle stores simply suggested "first on the card and then modified", saying that after the card is completed, you can go to the store to "regulate speed".

Guangzhou is about to implement the license for electric bicycles. In this regard, Nandu reporter interviewed a number of takeaway riders, who believe that they have used or are using modified electric bicycles. Most of them still have a fluke mentality, "the registration and control of electric bicycles will not be difficult for special travel groups such as takeaways." But some riders told reporters that they have just purchased and completed the modification of electric vehicles, and they are not sure whether they can be licensed in the future, "it cost more than five thousand yuan to buy a car and modify, to be honest, they are also worried about whether they can be licensed."

However, in order to attract customers, some merchants give advice - "first put on the card and then modify". In mid-September, Nandu reporters secretly visited an electric car store on Guangxin Road in Guangzhou's Huangpu District. The instructions for the use of various electric bicycles sold by the store all read "speed limit 25km/h", but the clerk told reporters, "You can adjust, then the mobile phone will change it for you, and then you will be transferred back when you are on the card." You can also tune it yourself, it's very simple, just a code. ”

In early October, the reporter went to the area around Dongpu Avenue in Tianhe District for a secret visit. In an electric vehicle store, the reporter mentioned that the electric bicycle that meets the new national standard will generally issue an alarm sound when it reaches a certain speed, and the store told the reporter that to remove the alarm sound, it is necessary to unlock the preset speed first. For the implementation of the new regulations on electric bicycles in Guangzhou, although the store emphasizes that the modified electric vehicles may be seized by the traffic police, but at the end of the day, it is suggested that "when the time comes, it is also possible to unlock the card."

The electric car store suggested that the reporter wait until the time comes to get on the card before unlocking.

When Nandu secretly visited, an electric bicycle shop owner told reporters that there was a "soft solution" and a "hard solution" to the speed limit of electric vehicles. "Soft solution" is generally not obvious to speed up and increase endurance, if you can not meet the requirements of the modification, you must "hard solution".

So, what is the "soft solution" and "hard solution"? Nandu reporter investigation found that the so-called "soft solution" is the use of "decoder" or a series of "dark codes" to modify the speed limit program of the chip with the car to achieve the purpose of modification.

The reporter further investigated and found that different electric vehicles have different "decoding" steps, and some electric bicycle manufacturers will preset the "backdoor" program, as long as the "dark code" set on the upper can unlock the speed limit. After "decoding", a new national standard electric bicycle with a speed limit of 25km/h can be increased to more than 40km/h.

Nandu reporter noted that as early as June 2016, when the Guangdong Provincial Public Security Department, the Guangdong Provincial Administration for Industry and Commerce, and the Guangdong Provincial Bureau of Quality and Technical Supervision jointly issued the "Notice on Strengthening the Management of Electric Bicycle Controllers", it was found that some electric bicycle models used controllers equipped with speed limiting devices, and preset cheating methods including plug-in insertion, cutting lines and even unlocking through a combination of brakes and rotary handles, so that the speed limiting device failed to improve speed. This preset cheating method is that the electric bicycle manufacturer leaves the "back door" for the purpose of "soft solution".

The "hard solution" mainly includes changing the battery, changing the circuit ("controller"), changing the motor, etc., which can generally be more obviously accelerated or increased the endurance, but the price of the "hard solution" is more expensive than the "soft solution".

The staff of the Guangdong Bicycle and Electric Vehicle Industry Association told Nandu reporter that the so-called "soft solution" speed change is more debugged on the controller, and the upper limit of the speed increase will be different according to the motor power and battery parameters. The so-called "hard solution" often occurs in the maintenance point of second-hand cars, and the speed increase is most related to the motor power and battery capacity.

Nandu reporter inquired about the new national standard of electric bicycles and found that the new national standard requires that the software and hardware of electric bicycles must have anti-tampering design, to prevent unauthorized modification or modification of the maximum speed, power, voltage, pedal riding ability, and there must be a battery tamper-proof setting. The relevant personnel of the Guangdong Bicycle and Electric Vehicle Industry Association said that the production design level can indeed have measures to prevent unauthorized changes in speed and other functions, and strengthening supervision at the production enterprise level and increasing sampling products can reduce some illegal practices.

Relevant people in the Guangdong Bicycle and Electric Vehicle Industry Association believe that changing the power system of electric bicycles may change the design balance of the whole vehicle, and excessive speed may also increase the risk factor during driving. After the modification of the electric bicycle, if the battery is changed the charge and discharge mode, it may cause a variety of problems, including battery explosion. It is estimated that about 70% of lithium batteries and 30% of lead-acid batteries are currently used in electric vehicles in Guangdong. The two kinds of power batteries have their own advantages and disadvantages, lithium batteries have a longer service life, but the assembly of battery cells is uneven, and unsafe products may appear.

The above-mentioned person suggested that on the one hand, the relevant competent departments continue to strictly investigate electric bicycle products that do not meet the new national standard, on the other hand, as a consumer, they should also buy electric bicycles with CCC certification, do not modify them privately, and cannot use non-original charger to charge.

Nandu reporter inquired that in March 2019, the State Administration of Market Regulation, the Ministry of Industry and Information Technology, and the Ministry of Public Security jointly issued opinions on strengthening the implementation of national standards for electric bicycles, which requires that after the implementation of the new standards, local market supervision departments should strengthen the supervision and inspection of the sales of electric bicycles, strictly investigate and punish the illegal sale of electric bicycles that do not meet the new standards and have not obtained CCC certification, as well as illegal modification, assembly, and tampering with electric bicycles.

The reporter noted that from March 15 to April 15 this year, the Guangzhou Municipal Market Supervision Department launched a special action to crack down on the production and sale of illegally modified electric bicycles throughout the city. The relevant person in charge of the Guangzhou Municipal Bureau of Market Supervision said in an interview with the media that the current electric bicycle modification mainly has the following situations: tampering with the speed of the vehicle, so that the speed exceeds 25 km / h; modifying the type and capacity of the battery, by modifying the body structure to install the number of batteries; tampering with the motor and other power devices. The Municipal Market Supervision Bureau said that if the general public finds suspected production and sale of electric bicycles without CCC certification marks, assembly, illegal installation, modification and other illegal acts, they can call the 12315 and 12345 hotlines to complain and report, and the market supervision department will investigate and deal with it according to law and implement the reward system for reporting.

Nandu reporter also noted that in July this year, the Guangzhou traffic police said at its press conference that it will cooperate with the municipal market supervision department to strictly investigate the illegal modification of electric bicycles, and continue to carry out inventory and rectification for the situation that electric bicycles are reserved for "modification functions", "battery installation locations" and "one-click switching speed settings" when they are produced.
