尼日利亚采购需求：机动三轮车、电动三轮车、电动滑板车、新能源汽车、零配件

I came across your advertisement for the electric Tuk-Tuk tricycles, specifically the wagon type, and I'm very interested in purchasing several units for commercial use in Nigeria. I'm looking to buy enough to fill a 20ft container, and would like to know the dimensions of the carton for this tricycle. Additionally, I would appreciate details on the price per unit, as well as how many units can fit into a 20ft container. It's important that the tricycles have a lithium battery and meet specified performance criteria. Also, please provide shipping costs and any available images or videos of different models along with their specifications. I've researched a few other options, but I'm keen on working with your company due to the quality I've seen. Looking forward to your prompt and competitive pricing!
