Our warranty covers all new e-bike manufacturing defects for 2-year from the date of purchase. If it meets the maintenance standards, we will repair your electric 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 bike needs to be returned for repair, we will work with you to minimize the cost and workload.
