巴基斯坦采购需求：三轮车电动机，成人机动三轮车，三轮三轮车，电动三轮车，乘用三轮车

I'm interested in getting a detailed quote for a specific type of electric tricycle designed for adult passengers. The tricycle should meet EEC and DOT certification standards and be equipped with a powerful motor, ideally around 1000W. Additionally, I'm looking for seating options that can accommodate up to three adults comfortably, with a total weight capacity of around 400 kg. Please provide pricing in Pakistani rupees, including options for different power configurations (800W, 72V, 48V, 60V) and whether there's an open body design available. I also appreciate any information on bulk purchase discounts or lead times for delivery. Looking forward to your prompt response!
