In order to facilitate packing, the front wheel, motorcycle handle, pedals, front fender and other parts are not installed, and need to be installed by yourself after receiving the goods. We will ship the installation tool with the packing.(You can refer to this video to install https://youtu.be/fOAnvx-hpuo) Since the goods contain engines and are anti-dumping products, the freight generated by door-to-door transportation is about 1.8 times the value of the product. The cost depends on the order quantity and delivery address. The goods will be delivered by UPS after customs clearance at the US port, because the US UPS has the problem of violent delivery. We recommend that you choose a package upgrade. We are not responsible for any damage caused by your failure to choose a package upgrade. The default is to use pearl cotton to pack, if the goods are damaged after receipt, please provide photos. We will resend the accessories, and the shipping costs incurred will be split equally between the buyer and the seller. The US warehouse is located near the port of Long Beach, California. To avoid damage caused by UPS delivery, if you are close to the port, please go to the warehouse to pick up the goods. (delivery fee 10 USD/piece)
