We’re very sorry to hear about your experience and understand your frustration.
After carefully checking our records, we need to clarify that your bike was not purchased from our website:
https://www.gunai-ebikes.com/
Please note that we can only provide after-sales service, spare parts support, and warranty coverage for customers who purchased directly from our official website. Unfortunately, we do not have access to orders, parts compatibility, or warranty responsibilities for bikes purchased from third-party sellers or unauthorized websites.
If your bike was purchased from another platform or seller, we strongly recommend contacting the original seller directly, as they are responsible for product quality, spare parts supply, and after-sales service.
We sincerely regret that we’re unable to assist further in this case, and we appreciate your understanding. For future purchases, to ensure full support and warranty protection, please make sure to buy directly from our website.
