I believe the issue may be with a sticking sensor in the brake lever assembly. The sensor shuts down power assist and throttle when either brake is applied. Try unplugging the left brake lever assembly first.

Go to the left brake lever, find the power wire coming off the lever, follow the wire down in front of the steering stem. Unplug the wire to see if the issue clears up. If not, repeat on right side.

If that fixes the issue, call Rad and have them send you a new brake assembly under warranty.
