After-sale service in urban areas is not good. If you change tires and inner tubes, you have to look for a long time, otherwise it is very far. It is a bit difficult to achieve environmental protection and penetration. It is necessary to do a good after-sales service, otherwise the tires are broken. Few bike shops will repair (especially the rear wheels). It should be to increase the after-sale repair points and service bases, or the head office will send a special vehicle for repairs (must be reasonably priced), otherwise they will be sold in Nanzi District or fixed Order maintenance, this will cause some confusion in consumer spending. And because of the products displayed at Carrefour, it is really necessary to pay attention to the after-sales service to spread it. Otherwise, you can only do business once, and you will not buy back or recommend friends and relatives to buy next time. Thank you, I hope there is room for improvement.
