Motor does not work, but the LCD display is on and is showing no errors

If your motor stops working but the LCD stays on and there are no error codes. The first thing to check is the two motor inhibitors located on the brake lever. 

The motor inhibitor switch (or motor cut sensor) is designed to turn the motor off when you use the brakes. This is a safety feature to prevent the simultaneous operation of the throttle and the brake. 

In some instances, the motor inhibitors can be activated even when you are NOT using the brakes. The result is that the e-bike will not provide assistance with either the throttle or the pedal assist.

Perform the following steps to check if the motor inhibitors switch is not functioning normally.
