C3 - 1. Footrest Installation & Removal

Q: How do I fix screws that are too tight, stripped, or cannot be installed?

Solution:

1. Use a heat gun to warm the screw.
2. Note: Do not touch the heated screw directly with your hands.
3. Attempt to remove it while warm.
4. If it still cannot be removed, we recommend taking it to a local auto repair shop for professional assistance.

C3 - 2. Power & Starting Issues

Q: What should I do if the vehicle won't start or won't charge?

Steps:

1. Check the throttle cable connections.
2. Ensure the brake lever returns to its original position (not stuck).
3. Check the motor wiring for loose connections.
4. The Pedal Test: Turn the pedal 2 full revolutions.If the chain drives the motor without electric assist, the throttle is faulty.If there is no assist at all, the controller is faulty.

C3 - 3. Tire Maintenance

Q: What if the tire is punctured, leaking, or bulging?

Solution: Check the outer tire for punctures first. If there are no visible punctures, the inner tube may be losing air—try reinflating it. Replace the inner tube if inflation does not solve the issue.

C3 - 4. Lighting Issues

Q: What if the front or rear lights are not working or always on?

Solution: If your brake light worked initially but doesn't now, remove the battery case and check if the tail light cable is loose. If the connection is secure but it still doesn't work, the parts may need replacement.

C3 - 5. Range & Speed

Q: Why is the range short or the speed lower than advertised?

Solution: Battery range is affected by load weight, road conditions, and low temperatures. Please fully charge the battery and record the actual range for feedback to us.

Note: Speed limit removal is available, but please note this will reduce the battery's service life.

C3 - 6. Error Code Reference

CodeMeaningRecommended Actions

W2A/W2B - 1. Battery & Performance

Q: Why is the battery life short or draining rapidly? Solution: Battery range can be affected by multiple factors: load weight, road conditions, and low temperatures. Please fully charge the battery and record the actual range to provide feedback to us.

Note: Speed limit removal is available, but please note that this will reduce the battery's overall service life.

W2A/W2B - 2. Power & Starting Issues

Q: What should I do if the vehicle won't start or the charger shows a green light? Steps:

1. Check the throttle cable connections.
2. Check the brake lever return (ensure it is not stuck).
3. Inspect the motor wiring for any loose connections.
4. The Pedal Test: Turn the pedal 2 full revolutions.If the chain drives the motor without electric assist, the throttle is faulty.If there is no assist at all, the controller is faulty.

W2A/W2B - 3. Throttle Issues

Q: What should I do if the throttle is damaged or unresponsive? Solution: Check if the throttle connector is properly and securely connected. If the connection is fine but the throttle still fails to respond, the throttle component needs to be replaced.

W3 - 1. Power & Starting Issues

Q: What should I do if the vehicle won't start or the charger shows a green light but won't charge?
Steps:

1. Inspect the throttle for any physical damage.
2. Check if the motor's waterproof cable connection is loose.
3. Open the battery compartment to inspect if any internal wires are crushed or disconnected.

W3 - 2. Battery & Performance

Q: Why is the battery life short or draining rapidly?
Solution: Battery range is affected by several factors, including load weight, road conditions, and low ambient temperatures. Please fully charge the battery and record your actual riding range to provide feedback to us.
Note: While speed limit removal is available, please be aware that using this feature will reduce the battery's overall service life.

W3 - 3. Throttle Issues

Q: What should I do if the throttle is damaged or not working?
Solution: Check if the throttle connector is properly and securely connected. If the connection is fine but the throttle still fails to respond, a replacement throttle is required.

W3 - 4. Sudden Shutdown

Q: What causes the vehicle to shut down suddenly during a ride?
Solution: This issue is typically caused by a faulty controller. A replacement controller is required to resolve this.

W3 - 5. Braking System

Q: How do I fix brake rubbing or disc brake squealing?
Solution: These noises are often caused by frequent braking, which moves the disc out of alignment. The brake disc needs professional adjustment. We do not recommend self-adjustment; please consult a local bicycle repair technician for service.

W3 - 6. Tire Maintenance

Q: What if the tire is leaking or damaged?
Solution: Check the outer tire for punctures first. If no punctures are visible, the inner tube is likely losing air—try reinflating it. If it continues to leak, the inner tube must be replaced.

F2 - 1. Tire Maintenance

Q: What should I do if the tire is deformed or leaking? Solution: Check the outer tire for punctures first. If no punctures are found, the inner tube is likely losing air—try reinflating it. If it continues to leak, replace the inner tube.

F2 - 2. Gear Shifter & Derailleur Issues

Q: What should I do if the gear shifter is not working or there are gear engagement issues? Solution:

1. Tool Needed: Use the M5 wrench included in your tool kit.
2. Adjustment: Locate the adjustment hole on the top of the derailleur. Insert the M5 wrench and gently pry it outward.Note: Do not apply excessive force to avoid over-deformation.
3. Check Chain: Rotate the pedals to observe whether the chain engages with the gears properly. If it still fails to engage, proceed to the next step.
4. Fine-tuning: Adjust the cable tension at the rear end of the derailleur. Gradually tighten it until the chain engages smoothly and rotates freely.
