QuoteError detectionFor all 5 lights flashing, it says "Error type: Communication fault"
Your RadExpand is equipped with an error detection system integrated into the display and controller (see "Electrical controls and operation" on page 27 for more information). In the rare event of an electrical issue with the bike, you may see a specific combination of lights flash on the Pedal Assistance Level lights on the display. If this happens, we recommend that you cease operation, take a short video of the light(s) flashing if possible, and then go to the
Rad Power Bikes online Help Center (radpowerbikes.ca/help) for more information.
