1. choose the right rear trunk

Moderate weight: Avoid choosing too heavy a rear trunk. Excessive boxes will increase the burden on the rear of the battery car and affect stability. You can choose a lighter but strong plastic or aluminum alloy tail box.

Appropriate size: Choose the rear trunk with matching size according to the size and model of the battery car. A too large tailbox may increase wind resistance and affect handling; a too small tailbox may not meet storage needs and may not be stable enough after installation.

Reliable quality: Choose a rear tail box with good quality and fine workmanship to ensure that the box and connectors are durable and not easy to damage.

2. the correct installation tools and accessories

Tools: usually need a wrench, screwdriver and other tools to install the tail box. Ensure that the tools are complete and suitable for a smooth installation.

Accessories: generally include mounting brackets, screws, nuts, etc. These accessories should be matched with the rear trunk and battery car to ensure firm installation.

3. correct installation of rear trunk bracket

Determine the installation position: usually the rear trunk bracket is installed on the rear shelf of the battery car. Choose a flat and stable position to ensure that the bracket can be firmly fixed on the shelf.

Install the bracket: Use screws and nuts to fix the bracket on the shelf. Make sure that the screws are tightened and there is no gap between the bracket and the shelf. When tightening the screws, you can use a wrench to increase the force appropriately, but do not use excessive force to avoid damage to the screws or shelves.

Check the stability of the bracket: After installing the bracket, gently shake the bracket to check whether it is firm. If the bracket is loose or shaken, recheck the installation steps to ensure that the screws are tightened.

4. installation rear trunk body

Place the trunk on the mounting bracket, making sure the trunk is aligned with the bracket.

Use screws or other connectors to fix the box to the bracket. Depending on the design of the rear trunk, different connection methods may need to be used, such as screw fixing, snap connection, etc. Ensure that the connectors are firmly installed and the box will not loosen or fall off during driving.

Check the stability of the box: After installing the box, check the stability of the rear box again. Shake the box gently to check for looseness or shaking. If the box is unstable, you can adjust the position of the connector or tighten the screws to ensure that the box is firmly fixed on the bracket.

5. adjust the position of the rear trunk

Horizontal adjustment: Ensure that the rear trunk is installed in a horizontal position and will not tilt to one side. If the rear trunk is not installed horizontally, it may affect the stability of the battery car, and may cause the box to shake or fall during driving.

Height adjustment: according to personal needs and riding habits, adjust the height of the rear trunk. Generally speaking, the height of the rear trunk should not be too high, so as not to affect the riding line of sight; it should not be too low, so as not to encounter the ground or other obstacles during driving.

Front and rear adjustment: Ensure that the rear trunk keeps a certain distance from the rear wheels of the battery car to avoid friction with the rear wheels during driving. At the same time, it is also necessary to ensure that the rear trunk is not too forward, affecting the balance and control of riding.

6. for testing and adjustment

Test ride: After installing the rear trunk, perform a test ride to feel the stability and handling of the battery car. Observe whether the rear trunk is loose, shaking or abnormal noise during driving.

Adjustment: If stability problems are found in the rear trunk during the test ride, it can be adjusted according to the specific situation. For example, you can adjust the position of the bracket, tighten screws, replace connectors, etc. If the problem still cannot be solved, you can consider consulting a professional or replacing the rear trunk.
