We’re truly sorry to hear about your experience, and we understand how frustrating this situation must be—especially when it involves your son’s safety and enjoyment.
After your initial contact in April, we responded as quickly as possible and provided a replacement front fork free of charge once the issue was identified. As noted, the front wheel assembly requires manual installation, and in many cases, issues like wheel detachment are related to improper axle installation or insufficient tightening before riding. Even so, we did not hesitate to support you with replacement parts at that time.
Following your most recent message, we carefully reviewed the video you provided. Based on our assessment, the repeated issue appears to be caused by the front wheel axle not being properly secured before use. This can unfortunately lead to the wheel loosening during riding and, in turn, damage to the fork.
We understand you mentioned having the bike checked by a local shop, and we respect that effort. However, after several months of use, if there had been an inherent product defect, it would likely have been evident from the very beginning rather than occurring intermittently.
As a gesture of continued support, we offered to send a replacement axle to help resolve the root cause. Regarding the fork, it falls outside the warranty coverage under these circumstances, which is why we’re unable to provide a free replacement. We sincerely apologize if this feels disappointing, but we aim to apply our warranty policy fairly and consistently.
In addition, our support team has already worked to secure an alternative solution for you—please kindly check your inbox for further details.
We truly value your feedback and will continue working to improve both our products and service. If you’re open to it, we’re still here to help you get the bike safely back in working condition.
Thank you for your understanding.
