For all fault problems, the buyer (e - commerce party) shall provide problem pictures / problem videos, and the seller shall be responsible for providing solutions and after - sales parts. If the seller has provided the buyer (e - commerce party) with free replacement parts and discount compensation, it shall be deemed that the buyer (e - commerce party) has accepted the risk of repair, and in such cases, the return service will no longer be available. Please use the compensation clause with caution. (Serial numbers / codes are required for battery, motor and charger failures)

All products requiring after - sales service shall provide the shipping logistics number, which shall be subject to the receipt date displayed on the logistics website.

Minor scratches on the vehicle body are not considered product quality problems, and returns will not be accepted. If the buyer (e - commerce party) minds, please place the order carefully. Generally, there will be no scratches. In such cases, appropriate compensation can be given to the buyer (e - commerce party), with the maximum compensation amount of 30 US dollars (the compensation fee will be determined according to the actual damage assessment).

If the buyer (e - commerce party) insists on returning the bicycle without using it, it shall be handled as an "unconditional return". The logistics cost arising from the return shall be borne by the buyer (e - commerce party): the logistics fee is 1300 RMB (if the buyer sends it by themselves, they shall bear the shipping fee of 650 RMB); In addition, the refund amount will be arranged according to the return status of the product. If it affects secondary sales, a full refund cannot be arranged.

If the bicycle cannot be used normally due to damage caused during transportation, feedback shall be given within 7 days with supporting evidence, and an unconditional return is acceptable.

Unconditional return of goods: Within 7 days from the date of receipt, unconditional return is supported if there are no signs of use and it does not affect secondary sales (for unconditional return, pictures of the whole vehicle are required to apply for return). The buyer (e - commerce party) shall bear the round - trip logistics fee (subject to the actual bill); Unconditional return applications will not be accepted after 7 days. If the returned bicycle has been used and affects secondary sales, a full refund cannot be arranged, and a discounted refund will be given according to the actual usage.

Within 30 days from the date of receipt of the product, if there is a quality problem that makes it unable to be used functionally (i.e., the problem cannot be solved by replacing parts), an unconditional return is acceptable. After the goods are returned to the warehouse, technicians will be arranged to inspect the bicycle. If the actual situation is inconsistent with the facts fed back by the buyer (e - commerce party), the buyer (e - commerce party) shall bear the logistics fee (subject to the actual bill) and the depreciation fee (based on the vehicle condition).

For returned goods caused by abnormal logistics return due to wrong logistics address provided by the buyer, or returned goods due to the buyer's refusal to accept the goods, the logistics cost of the returned goods shall be borne by the buyer (e - commerce party): the return fee is subject to the actual bill.
