First, please be sure to review our assembly video and guide, along with our compatibility section, to ensure the electron wheel will work with your bike.
If you are still having issues with your wheel, please send us an email specifying the issue. We will get back to you quickly and try to identify the problem. We may request a couple pictures to help our engineering team determine the cause.
If there is a hardware issue with the unit, you will need to ship the wheel back to our warehouse in California where we will run a full diagnostic and work to resolve the problem.
