Warranty Policy
Warranty Policy
Our warranty covers all new scooter/bike manufacturing defects for 1-year from the date of purchase. If it meets the maintenance standards, we will repair your electric scooter/bike and bear all related parts, costs, and labor costs. If you need repairs or the parts are not covered by our warranty, please let us know and we will try our best to help-usually we can diagnose the problem and send you paid replacement parts. If your scooter/bike needs to be returned for repair, we will work with you to minimize the cost and workload.
We will replace any parts deemed to have been damaged during shipping. Shipping damage must be reported to DUOTTS within 14 days of shipment arrival. This applies to all products including bikes and accessories.
DUOTTS will request additional documentation (such as video) to assist with accurately diagnosing the problem and processing the warranty claim. Most warranty parts are fulfilled 1-10 business days after the request is put into our system by a customer service representative. Replacement parts will not be sent until evidence has been provided to DUOTTS.
Warranty parts are sent using UPS First Class, FedEx Express, or DHL depending on the size of the part. Warranty parts will not be expedited.
Items including the chain, tires, wheels, tubes, battery handle, brake pads, cables and housing, grips, and spokes are considered wear items. These items wear down with normal use and are not covered under warranty. You are responsible for replacing and maintaining these worn items.
