Upgrade the lithium battery for ultra-long battery life?
Change to a high-power motor to get super horsepower?
Extra seats for hassle-free transport?
......
Some sales and maintenance stores
With "can be modified"
"Upgrading the 'little electric donkey'" is the selling point
to attract consumers
These behaviors seem to be convenient for themselves
But
Gotta pay attention
Feel free to replace the parts of your e-bike
Unauthorized and unsecured features
In the case of testing and certification
Accessories are added to the e-bike
All of them belong to illegal assembly and modification!
Why can't you build an electric bike?
Because of a lot of e-bike accidents
It is caused by illegal assembly
so
Common e-bikes
What are the situations of assembly and modification?
What are the dangers of illegal assembly?
How to identify illegal assembly?
Ah Xiao, let's give you a science popularization
Common cases of illegal assembly and modification
■ Tamper with the speed limit, the maximum speed limit of the new national standard electric bicycle is 25km/h, and the maximum speed can reach 60km/h after modification;
■ Remove the speed limiting device and remove the pedal riding equipment;
■ Reserve the extended battery interface, set up the battery bracket for peripherals, and install or replace the batteries that do not meet the regulations of the original car;
■ Installing external facilities such as umbrella frames and canopies will affect the handling and stability of electric vehicles;
■ Spraying or installing signs, patterns, sirens, etc. similar to special vehicles without authorization, causing confusion and misunderstanding;
■ Illegal modification of accessories, such as lengthening cushions, installing armrests, etc.
Illegally assembling and modifying electric bicycles
What's the harm?
■ Small modifications, the danger is difficult to control
Modifying an electric bike will cause the weight of the car to change, and the handling and braking will become less sensitive, especially when the speed limit is lifted, and the car is very easy to lose control when speeding, which is really very dangerous.
■ Change the wiring and be careful of spontaneous combustion
Many modifications will change the circuit, if the small wire is subjected to a large current, the circuit will be unstable, prone to short circuit, which will cause spontaneous combustion.
■ Modified batteries are equivalent to "buried mines"
After the battery is modified, the terminal and wire may be damaged, and if the wire is randomly snapped and ignited, it is easy to ignite the hydrogen gas that collects inside the battery during charging and cause an explosion.
■ The canopy shades the sun and also covers the view
Adding a canopy or parasol to the electric car will block the view and increase the wind resistance of the car, and the car will easily lose its balance in windy weather, and it may cause an accident if you are not careful.
How to identify an e-bike
Has it been illegally assembled?
Master 4 tips
Let you become a "little expert" who chooses and sees cars
↓↓↓
■ The "secret" on the certificate of conformity
Each e-bike has a unique all-digital vehicle code, which is the vehicle's "ID card". Check whether the vehicle code on the "Electric Bicycle Product Certificate" is consistent with the code marked on the vehicle.
In addition, there is other information on the certificate, before purchasing, you should check whether the outline diagram on the certificate is consistent with the actual shape of the vehicle, and whether the type of battery marked on the certificate is consistent with the type of battery actually carried.
■ "Great wisdom" in size
The height, width, and center distance between the front and rear wheels of the electric bicycle have a clear numerical range (as shown in the figure below). Before purchasing, carefully check whether the actual value meets the regulations.
■ "Little Secret" in the Socket
Different types of batteries use different socket forms. If you notice that your e-bike's socket and battery don't match, be careful: it's likely a sign of an illegal modification!
■ Check the vehicle configuration
According to the common assembly and modification situations listed above, check whether there is any installation or modification behavior.
