DoNews March 15 news (Zhang Jia) In recent years, traffic safety accidents caused by the speed of electric bicycles have occurred frequently.
According to the mandatory national standards of the "Electric Bicycle Safety Technical Specification", the speed of electric bicycles does not exceed 25 km / h. However, some electric bicycles with new national standard license plates are still speeding on the road.
Some e-bike stores in the city say they can adjust the speed, and they almost all admit that they can increase the speed to 35-40 kilometers per hour by decoding. Sales staff said that although the national standard has a clear limit on the speed of electric bicycles, they can use technical means to lift the speed limit of electric bicycles after the license is licensed. This technique is called "decoding".
Hello electric bicycle store salesman: We have a decoder, after solving the code, it will lift the restriction, the original it is the national standard, can only ride 25 km / h, after the solution it can ride faster.
Luyuan electric bicycle store salesperson: We have a decoder, just get the code.
Xinri electric bicycle specialty store Salesperson: Uncoded, about 35 km / h. Decoding is convenient, very fast, just a matter of minutes.
Golden Arrow Electric Bicycle Specialty Store Salesperson: This is an open secret, every place if not decoded, no one will buy.
Tailing electric bicycle store sales staff: the instrument always shows 25 km / h, even if the traffic police caught it is fine, a twist or 25 km / h.
Hello electric bicycle specialty store Salesperson: The table only shows 25 km / h, but it runs faster than 25 km / h.
New Day electric bicycle store salesperson: The display shows 25 km / h, but the speed is indeed 35 km / h, we adjusted it ourselves, this display can not be 35 km / h. If the police see 35 km / h, it must be exceeded.
Paragraph 3 of Article 4 of the "Electric Bicycle Safety Technical Specification" clearly requires that the software and hardware of the electric bicycles shipped by the manufacturer should have an anti-tampering design to prevent unauthorized modification or modification of the maximum speed.
With such regulations, why can these dealers easily lift the speed limit of electric bicycles? Golden Arrow electric bicycle store sales staff said: This is the manufacturer with. In the warehouse of andda, the staff took out the decoder they had equipped for the store to lift the speed limit, and with a simple press of the remote control, the speed limit was lifted.
Through the picture can be seen, the speed after the lifting of the speed limit is obviously much faster than before, according to the manufacturer's staff, the speed after the lifting of the speed limit can basically reach about 35-40 kilometers per hour. Unlike The Anda, the decoder of the Wuxi Hama Carriage Industry is a device installed near the power supply, and the speed limit is lifted after the power is turned on. The reporter tried to ride the decoded electric bicycle, and it was easy to speed.
The "Electric Bicycle Safety Technical Specification" clearly stipulates that when the driving speed reaches 15km/h, the prompt tone is continuously issued, but this prompt tone used to warn safety is eliminated by the manufacturer's decoder. Jiangsu Lanjun Technology Co., Ltd. is a manufacturer specializing in the production of electric bicycles in Wuxi, and they also prepare a decoding device for dealers to lift the speed limit. Jiangsu Lanjun Technology Co., Ltd. Manager Xie said: Lifted about 40 km / h.
Subsequently, the reporter visited a number of electric bicycle manufacturers such as Oupai, knife, and green energy, and found that they all prepared decoding devices for dealers, so that electric bicycles that should have a speed of no more than 25 kilometers per hour could easily speed. Oupai electric bicycle manufacturer Staff: If you decode it, you are pulling it to the end, and it can be automatically decoded in a few seconds. Small knife electric bicycle manufacturer Regional Manager: Decoding is definitely not allowed when leaving the factory, but in our customer's place, we have decoders.
In order to ensure traffic safety, the relevant technical specifications clearly require manufacturers to have a design to prevent tampering with the maximum speed, but in fact, the manufacturer not only reserves the back door behind the manufacturer, but even provides a device for the dealer to lift the speed limit.
