For an existing Jimsen order, send the model and order reference with the fault description, photos or video. Our team reviews the information and provides replacement-parts or remote technical support under the agreed warranty and order terms.
Jimsen provides a two-year warranty under the applicable order terms. The agreed policy determines covered parts, the warranty start date and exclusions for the supplied configuration.
Coverage does not automatically include every repair cost. Confirm responsibility for labour, freight and any return shipment in the order terms.
Send the model and order reference, the affected component and a short account of the fault: when it started, what happens and whether it is intermittent. Include any error message exactly as shown.
Jimsen reviews the evidence to identify the next diagnostic step or an agreed remedy. Do not open a battery pack or make unsafe electrical modifications to demonstrate a fault.
Use the supplied component reference when requesting a part. A model name or a similar-looking connector alone does not establish compatibility with a different production version.
Replacement parts and remote technical guidance can form part of the agreed remedy. Parts availability, charges and dispatch arrangements are confirmed for the request; no universal stock or response-time promise applies.
Before a bulk order, agree how local staff will identify the supplied build, operate it and report faults. Keep the accepted sample reference with the manual, component list and any agreed service instructions.
For branding or design changes, use our OEM/ODM service. For production photos and factory information, see our factory. Send service requests with the model and order reference to info@jimsenebike.com.
