美国采购需求：机动三轮车、电动三轮车、电动滑板车、新能源汽车、零配件

I'm reaching out to inquire about the pricing of your three-wheel electric bikes. We are interested in potentially placing a bulk order, so could you please provide detailed information on your available models? Additionally, it would be great to know about any specifications regarding battery life, weight capacity, and any unique features that set your bikes apart in the market. Also, if you have any promotional deals or discounts for larger orders, please include that information as well. Timely responses would be appreciated, as we're looking to finalize our purchasing decisions soon. Looking forward to your detailed quotation!
