Electric-assist bicycle displays typically require a series of tests to ensure their performance, reliability, and safety. Here are some common tests:

1. Functional Testing: Verify that all functions of the display are working as expected, including speed display, battery level, mileage, assist level indication, etc.

2. Environmental Testing: Ensure that the display operates normally under various environmental conditions such as high temperature, low temperature, humidity, vibration, etc.

3. Durability Testing: Simulate long-term usage conditions to check the durability of the display and the stability of its performance over time.

4. Electromagnetic Compatibility Testing (EMC): Ensure that the display does not suffer performance degradation due to electromagnetic interference and does not produce interference that affects other devices.

5. Water and Dust Resistance Testing: Considering that electric-assist bicycles may be used in various weather conditions, the display needs to meet certain standards for water and dust resistance.

6. Safety Testing: Check the electrical safety of the display, such as insulation strength, touch current, and battery safety.

7. Compliance Testing: Ensure that the display complies with relevant national and international standards, such as CE marking, RoHS directive, FCC regulations, etc.

8. User Interface Testing: Assess whether the display's user interface is intuitive and easy to use, whether the information display is clear, and whether the operations are convenient.

9. Software Testing: If the display includes programmable components or software, software verification and update mechanism tests need to be conducted.

10. Compatibility Testing: Ensure that the display is compatible with different brands and models of electric-assist bicycle systems.
