This hub motor core is a high-performance replacement part, designed to restore or upgrade your Wallke eBike's propulsion system. Please note it includes only the motor core and does not include the rim, spokes, freewheel, tube, tire, or outer motor casing. All Wallke eBikes come equipped with a motor, so purchase this item only if you need a replacement or an upgrade to your existing motor. For dual-motor eBike models, be aware that there are front motor cores and rear motor cores. Make sure to select the correct motor type to ensure proper fit and compatibility with your eBike’s drivetrain. This motor core is capable of delivering consistent and reliable power. Installation should be done carefully, and we recommend following our detailed product installation video to ensure correct setup and safe operation. To guarantee compatibility, we recommend providing your motor serial number when placing the order. Click "Add to Cart" and enter your motor number in the "Order Note". Each Wallke eBike has a serial number stamped on the motor core for easy identification. Additional Notes & Purchase Guidelines: Double-check your eBike model and motor core position (front or rear) before ordering to avoid fitment issues. If you are unsure about compatibility, contact our customer service before placing your order — we can guide you to select the correct motor core. Proper installation and regular maintenance are essential to maximize motor performance, lifespan, and safe operation. Only order a replacement motor core if your current core is malfunctioning, worn out, or if you need a backup for extended trips. Following these guidelines ensures that your Wallke eBike remains reliable, efficient, and safe for every ride.
