赞比亚采购需求：沙滩车、全地形车、多用途全地形车、110cc全地形车、柴油多用途全地形车、四轮摩托车

I'm interested in purchasing off-road quad bikes suitable for both kids and adults. I'm looking to buy a total of 60 units, but this is dependent on the pricing you can offer. It's crucial that the bikes are robust and designed for a fun yet safe riding experience for various age groups. Could you please provide me with a detailed quote, including the unit price, available models, and any additional features or options? Also, let me know about your lead time for delivery and minimum order quantities if applicable. Looking forward to your response!
