Dear valued customer,
Thank you for purchasing the wheel hub accessory from our official YOULONSPORT website.
Since the wheel hub is a large and heavy item, the shipping cost is considerably high. To make sure you receive the 100% correct and compatible wheel hub for your e-bike, could you please take a clear photo of the serial code located on your current wheel hub and send it to us?
Email: youlonrideservice@163.com
Once we receive the code, we will double-check and arrange the correct replacement item for you as soon as possible.
Thank you so much for your understanding and cooperation. Please feel free to contact us if you have any questions.
Best regards,
YOULONSPORT Customer Service Team
