It is possible to modify the speed, but it must not exceed 60 mph. Exceeding 60 mph would not comply with the new national standard for low-speed new energy electric vehicles. Below are some precautions for using electric vehicles: Regular charging: Generally, the battery starts discharging after leaving the factory. If left unused for one or two months, the battery will be completely drained. Over time, this will reduce battery performance and range. Therefore, even if not in use, the battery should be charged every half month to one month. Precautions: Many owners often forget to charge after use, leading to the necessity of using fast charging in emergencies. While one fast charge may not have a significant impact, frequent use can cause the battery to develop a bad memory effect, making it impossible to fully charge in the future, which affects travel and battery lifespan. Simply put, a regular battery can run 30 kilometers when fully charged, but fast charging may reduce this to just over 10 kilometers. Frequent use of fast charging can impact battery performance and shorten its lifespan.

I've talked to many e-bike users about this issue. New national standard e-bikes come with locked controllers from the factory, limiting speed to 25km/h at most. To go faster, you can flash the ECU or install a higher-power motor to bypass the speed limit. But I strongly advise against it! First, it clearly violates traffic laws—getting caught by traffic police could mean a fine of at least 500 yuan, and in serious cases, your vehicle might be impounded with penalty points. Second, safety is a major concern—the original braking system is designed for the speed limit, and modifying it increases braking distance, making sharp turns in the city or riding in the rain more prone to loss of control and crashes. In case of an accident, insurance companies may deny claims. If you really need higher speed, it's better to spend some money to switch to a compliant e-motorcycle or lightweight motorcycle—safer and worry-free.

As a commuter riding a new national standard e-bike, I've also thought about tweaking it for a bit more speed. Adjusting the controller or swapping in a more powerful battery can push it over 30km/h, which sounds tempting, but the reality brings endless headaches. The battery life plummets, tires wear out faster; once during rush hour, I nearly rear-ended a car, scaring me half to death. Cops are strict—I got fined 100 yuan for modifications, a total loss. For daily commutes, 25km/h is perfectly adequate. Modifying just adds risks and costs more. Honestly, if you want hassle-free rides, just stick to stock settings—it's not worth the trouble.

Is it safe to drive with the sunroof open on the highway?

It is not safe to drive with the sunroof open on the highway. Driving with windows open on the highway poses significant safety risks. Here are the reasons why it is not recommended to open windows while driving on the highway: 1. Increased fuel consumption: At high speeds, the car's streamlined design effectively reduces wind resistance. However, opening the windows disrupts the airtightness, leading to increased air resistance and consequently higher fuel consumption. 2. Increased noise: Opening the windows at high speeds significantly increases wind noise, reducing comfort. 3. Interior gets dirty: Driving with windows open on the highway naturally makes the interior/roof lining more susceptible to dust accumulation. 4. Increased risk of accidents: The typical speed on highways is around 120 km/h, and many drivers store luggage or tools in the trunk. Strong winds from open windows can cause imbalance, leading to traffic accidents.

Do Sedans Have a Radiator and Need Water Refill?

Sedans do have a radiator and require water refill. Generally, when a car is low on coolant, water is added as a temporary solution. Precautions for adding water to a new car are as follows: 1. Do not use ordinary water as a substitute for coolant; 2. Avoid mixing coolants of different colors and specifications; 3. When using coolants from different brands, try to drain the original coolant from the cooling system thoroughly; 4. Regardless of high or low temperatures, coolant should be used for the efficiency and longevity of the cooling system; 5. Tap water contains many substances that can easily cause rust and scale buildup. Coolant, on the other hand, can lower temperatures, regulate heat, and is less prone to deterioration and chemical reactions.

How to Repair Scratched Rearview Mirrors?

The methods to repair scratched rearview mirrors include using specialized repair agents or applying wax. Additional information on repairing scratched car rearview mirrors is as follows: 1. Before repairing, it is necessary to clean the scratches on the rearview mirror. You can first use coarse wax and then fine wax for the repair. 2. If the car is new and the first maintenance has not been completed, the scratches can be addressed by the maintenance personnel at the 4S store during the first maintenance. 3. If only the surface is scratched without exposing the black part, it indicates that the car's primer is not damaged, making the touch-up simpler. Due to different car brands using different paints, especially white paints which include pearl white, ivory white, matte white, etc., it is recommended that the owner go to a 4S store for repair in such cases.

Why is the temperature gauge normal when the thermostat is broken?

Thermostat damage temperature gauge normal reason is thermostat protection water temperature does not drop: The following is the relevant content introduction: 1. The working principle of the thermostat: The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, changes the circulation range of the water, and adjusts the heat dissipation capacity of the cooler to ensure that the engine works within a suitable temperature range. The thermostat must maintain good technical condition, otherwise it will seriously affect the normal operation of the engine. 2. The role of the thermostat: to prevent the engine from being too cold. After the engine is working normally, when driving at high speed in winter, if there is no thermostat, the engine temperature may be too low. The engine needs to temporarily terminate the water circulation to ensure that the engine temperature is not too low.

Is the Jetour X70 equipped with a dry dual-clutch transmission?

Jetour X70 is equipped with a dry dual-clutch transmission. Working principle of dry dual-clutch transmission: It uses two clutches to work alternately. The difference between dry and wet dual-clutch transmissions lies in the medium connecting the driving plate and the driven plate. Wet dual-clutch transmissions mainly rely on oil, while dry dual-clutch transmissions primarily depend on air. Basic structure of dry dual-clutch transmission: The friction plates of dry dual-clutch transmissions do not have sealed oil grooves and require air cooling for heat dissipation. Advantages and disadvantages of dry dual-clutch transmission: The advantage of dry dual-clutch transmission is fast gear shifting, while the disadvantage is its relatively low torque capacity.
