After-Sales Policy for Friction Drive Motors and Matching Products

I. Scope of Application

This policy applies to friction drive motors and matching products purchased through our official channels. The aforesaid products are all electromechanical accessories, not finished devices. They must be assembled onto corresponding equipment by users before use and cannot operate independently.

II. Warranty Terms

1. Warranty Period

Starting from the day after the user signs for the product, a 1-year free warranty service is provided. After the 1-year warranty period expires, paid technical support and spare parts supply services will be available.

2. Warranty Coverage

• Covered Failures: Refer to non-human-induced malfunctions caused by inherent design flaws, raw material quality issues, or production process defects of the product (e.g., motor damage, abnormal controller logic, significant battery capacity attenuation due to non-natural causes, etc.).
• Warranty Service Content: For defective products that meet the warranty conditions within the warranty period, free repair and replacement services for faulty components are offered. The warranty period of the replaced components shall be consistent with the remaining warranty period of the original product.
• Special Note on Batteries: Batteries are consumables, and natural capacity attenuation under normal use is not classified as a product failure. Within the warranty period, battery capacity attenuation will only be covered by the warranty if it exceeds 30% of the rated capacity (and is not caused by human factors such as long-term idleness or over-discharge).
• Warranty Definition for Wear Parts: The friction stickers applied on the motor surface are consumables and not covered by the warranty. Cables and start switches are external accessories with a 3-month warranty period.
• All consumable accessories are available for purchase on our official website.

3. Warranty Process

1. Application: Users are required to submit a warranty application to the official after-sales email address Qiroll@qiroll.com, providing the order number, product SN code, and clear fault videos/pictures.
2. Verification: The customer service team will respond to the application within 48 hours and provide remote troubleshooting guidance to the user.
3. Resolution:
   1. Accessory Replacement: If the failure is determined to be caused by faulty wear parts, we will deliver the replacement parts free of charge and provide professional installation guidance.
   2. Return-to-Factory Repair: For products confirmed to require factory repair and covered under the warranty, the return shipping fee (via regular logistics channels) will be borne by our company. The user shall prepay the shipping fee for sending the product back to the factory in principle; if the failure is ultimately determined to be a quality issue, the freight compensation can be negotiated.

III. Return Terms

1. Compatibility and Return Rules

This product is an electromechanical accessory, and independent debugging and optimization may be required during installation. Given the special nature of the product, the pricing has comprehensively covered cross-border transportation costs, tariff fees, and is positioned for high cost-effectiveness. Therefore, before the user places an order, we will confirm with the user whether their bicycle is compatible with this product.

If users have any questions about product compatibility, please verify and confirm with us via email. In case of installation failure after both parties confirm compatibility and the product is shipped, our company shall bear the relevant liabilities for return. If an order is placed without confirming compatibility with us, it will be deemed that the user has confirmed the product’s compatibility and installation feasibility, and we will not accept unconditional return requests by default.

2. Assistance Solutions for Non-Return Scenarios

If the product fails to function properly due to the user’s own reasons, our company can provide assistance services, including connecting users with product resale channels, recommending potential buyers with matching needs (e.g., the user’s relatives, friends, local prospective purchasers, etc.), and assisting users in debugging and optimizing the product to make it suitable for circulation and transfer.

IV. Disclaimer

1. Our company shall not be liable for product damage caused by improper installation, modification, disassembly, dropping, collision, contact with corrosive liquids (e.g., WD-40) or other human operational errors. However, we can provide paid repair services or supply matching accessories.
2. Our company shall not be liable for failures caused by failure to maintain and use the product in accordance with the product instruction manual or use in incompatible scenarios. However, we can provide paid repair services or supply matching accessories.
3. For product damage caused by force majeure (e.g., natural disasters, customs inspection and seizure) during cross-border transportation, if the user does not actually receive the goods, our company shall bear the liability; if the goods have been signed for and no objection is raised to us within 14 days, our company shall not assume relevant liabilities.
4. If the product serial number is blurred, altered, or missing, making it impossible to verify the product source and warranty period, we will not provide warranty services (the product serial number is marked on the top of the equipment via laser engraving technology).
5. Our motor products are accessories that need to be assembled onto the user’s corresponding equipment to operate normally. Since we cannot directly confirm the user’s ultimate usage purpose and environment, users must strictly comply with the relevant laws, regulations, and provisions of the location where the product is used, carefully evaluate and avoid various risks during use, and ensure the legal compliance, safety, and stability of equipment operation.
6. All products manufactured by our company strictly comply with the relevant certification standards and specifications of the countries and regions where they are sold. For technical indicators not covered by the certification scope, the design and verification are also carried out with safety and reliability as the core principle. We adhere to the safety bottom line and will never produce extreme products with excessive performance risks or exceeding safety thresholds.

Special Reminder: If users intend to modify the product by themselves, they must avoid extreme modification operations and are strictly prohibited from making any changes that exceed the bottom line of the product’s designed rated parameters.

V. Other Notes

Our company reserves the final interpretation right of this policy. Matters not covered herein can be resolved through negotiation with the after-sales customer service team.

The “sign-for date” referred to in this policy shall be based on the delivery completion date displayed on the cross-border logistics platform.

Due to the long cross-border logistics cycle, it is recommended that users unpack and inspect the product promptly upon receipt. If any issues are found, please contact the customer service team immediately for handling.
