Incident: Summary: Severe manufacturing defect involving reversed electrical polarity at the factory-installed battery port, resulting in a catastrophic short circuit, complete electrical system failure, and unrecoverable battery damage. The Defect: During factory assembly, the positive (+) and negative (-) wiring leads behind the main dual-battery connection port were crossed and connected in reverse polarity. The Incident & Progression: The vehicle initially exhibited irregular motor noise and progressive electrical resistance under normal operation. Upon attempting to isolate the issue with an authorized manufacturer-supplied component, the reversed polarity circuit caused a catastrophic backflow of current. This triggered a critical over-voltage loop, permanently destroying the electronic controller and locking out the main lithium-ion batteries. Certified Diagnostic Proof: A professional inspection conducted by certified technicians at an independent bicycle service
