Frequently Asked Questions about Electric Bicycle Parts FAQ

With the popularity of electric bicycles (e-bikes), more and more users have begun to pay attention to their parts' performance, maintenance, and replacement. From battery life to brake adjustment, common questions are endless. To help you better understand and use electric bicycles, we have compiled FAQs related to parts, hoping to escort your riding experience.

1. Battery-related questions

Q1: Why is my battery life shorter?

Cause analysis:

• Long-term overcharge and discharge of the battery leads to a decrease in capacity.
• The ambient temperature is too high or too low during use.
• Battery aging or abnormal battery management system (BMS).

Solution:

• Avoid frequent complete discharge of the battery. It is recommended to keep the battery in the range of 20%-80%.
• Store the battery indoors to avoid extreme temperatures.
• Check the battery regularly to see if it needs to be replaced. Usually, the life of a lithium battery is 500-1000 charging cycles.

Q2: How to charge correctly to extend the battery life?

• Use the original charger to ensure battery charging stability.
• Avoid charging when the battery is empty; it is recommended to charge when the battery is less than 20%.
• When not in use for a long time, recharge the battery to 50%-60% every 2-3 months.

2. Motor-related issues

Q1: Why does my motor make abnormal noise?

Possible causes:

• Dust accumulation or poor lubrication inside the motor.
• Aging or wear of the motor bearings.
• An abnormal motor controller signal causes unstable motor operation.

Solution:

• Clean the outside of the motor regularly to avoid accumulation of mud and sand.
• Check whether the motor needs lubrication and contact professional maintenance personnel to check the internal components.
• If a controller problem is found, replace or repair it in time.

Q2: How to detect whether the motor power is normal?

• Can it provide smooth and sufficient power during riding?
• Observe whether the power display data on the control panel fluctuates abnormally.
• If in doubt, use professional instruments to detect the motor output power or consult after-sales service.

3. Brake system problems

Q1: The brakes become insensitive, what should I do?

Possible causes:

• The brake pads are severely worn.
• The brake line is loose or broken.
• Insufficient hydraulic brake fluid.

Solution:

• Check the wear of brake pads regularly and replace them in time.
• Make sure the brake line is tight and replace it if necessary.
• If it is a hydraulic brake, check if the fluid is leaking and add special brake fluid.

Q2: How to adjust the sensitivity of the brake?

• Use the brake adjustment screw to fine-tune the distance between the brake pad and the brake disc.
• Hydraulic brakes need to vent bubbles and ensure that the system pressure is stable.

4. Controller and display problems

Q1: Why does the controller suddenly stop working?

Possible reasons:

• Battery power is low or wiring is loose.
• The internal circuit of the controller is short-circuited or damaged.

Solution:

• Make sure the battery has enough power and check whether the connection cable is firm.
• If the problem persists, replace the controller and select a model that matches the motor.

Q2: Why does the display screen show abnormal data?

Possible reasons:

• Poor contact of the display screen.
• Sensor or controller signal transmission error.

Solution:

• Check whether the display screen connection cable is loose.
• Restart the system or upgrade the firmware of the controller.

5. Tire and frame issues

Q1: How often do electric bicycle tires need to be replaced?

• Recommended replacement cycle: Replace tires every 3,000-5,000 kilometers according to riding frequency and road conditions.
• Judgment method:

1. Are there obvious cracks or wear on the tire surface?
2. Is the depth of the anti-skid texture lower than the safety standard?

Q2: How to choose the right type of tire?

• Road riding: Choose low rolling resistance and lightweight tires.
• Mountain riding: Choose wide tires, high grip, and wear-resistant tires.
• Mixed road: Choose all-terrain tires that are both comfortable and durable.

Q3: The frame is slightly damaged. Do I need to replace it?

• If it is only a surface scratch, the frame metal can be protected by repainting.
• If there are cracks at the welding point or key stress point, it is recommended to replace the frame immediately to ensure safety.

6. Other common questions

Q1: Is my electric bicycle safe on rainy days?

• Answer: Most electric bicycle motors and controllers have basic waterproof functions, but they should be avoided from prolonged exposure to heavy rain. Wipe dry and check the circuit after riding.

Q2: How to ensure compatibility when purchasing spare parts?

• Check the official recommended spare parts of the electric bicycle brand.
• Choose products that are compatible with original spare parts according to the model and technical specifications.
