Hi Emily, thank you for sharing your experience with us! Sorry to hear that the Rear Suspension product doesn’t seem to be compatible with your eDegree FS1. I understand how frustrating it can be when products don’t work together as expected. Unfortunately, according to the description, this product is specifically designed not to be compatible with the eDegree FS1. It’s possible that the design and functionality of the two products are not meant to work together seamlessly. Would you like me to help you find alternative solutions or products that might work better for your eScooter?
