Hi, thank you for sharing your experience with the iENYRID M4 Pro Max. Regarding the reduction in range after approximately 1500 km of use, battery performance can gradually decrease over time due to normal battery aging, riding habits, charging frequency, rider weight, terrain, and especially low-temperature environments, which can significantly affect overall range performance. As for the brake issue, the braking system can usually be adjusted and maintained to improve performance. We recommend contacting our after-sales support team for brake adjustment guidance videos. You can also find related maintenance and adjustment tutorials on our official YouTube channel. We appreciate your feedback on the display lock and lighting features, and your comments are valuable for helping us continue improving our products and customer experience.

Dear Valued Customer, We sincerely apologize for the negative experience you encountered and truly appreciate your honest feedback. In response, we immediately liaised with all relevant colleagues to identify where our service process fell short. Our investigation revealed several critical areas requiring improvement: Guaranteed Response Time: Despite time zone differences, we must enforce strict oversight to ensure customer service responds to all inquiries within 24 business hours, particularly when calls cannot be answered. Inventory Management: While spare parts are typically shipped within 72 hours, we discovered multiple cases (including yours) where orders could not be fulfilled due to stock shortages. We are restructuring our parts inventory protocol. Proactive Communication: When parts are out of stock, our team must promptly contact customers to explain the situation, apologize, and offer clear options: refund or continued waiting with regular updates. Choosing iENYRID among numerous brands is a privilege we deeply value. We are profoundly honored by your trust yet deeply remorseful for failing your expectations. iENYRID exists to spread the joy of riding worldwide—yet our errors brought you inconvenience rather than delight. This fundamentally contradicts our brand ethos. To rectify this, we have initiated rigorous internal reviews and strategy meetings to prevent recurrence. Regarding your order, our records confirm the spare parts were shipped on the 16th of this month, and the tracking number was shared by our team. We sincerely apologize again for your dissatisfaction. Your candid feedback is invaluable—it drives us to become better. iENYRID Team
