Recently, customers often ask us that the speed of the bicycle suddenly changes from 50 KM/H to 25 KM/H. In fact, it is caused by a wrong operation. The following is a quick way to release or set the speed limit.

Follow the steps below to set speed limit/unlock speed limit: Step 1. Hold the brake lever tightly (you only need to hold one, the left or right brake is fine), then turn on the screen, press and hold the brake lever for about 20 seconds and then release it Step 2. Set it to PAS5, twist the accelerator, and check whether the speed limit setting/unlocking is successful. Once you're done, let us know if you fixed the issue.
