英国采购需求：电动三轮车，休闲三轮车

I'm looking for a reliable supplier for mobility electric motorcycles. Ideally, I need models that offer a good balance of performance and battery life, suitable for urban commuting. Please share your available options and any specifications that can help me understand their capabilities better. Additionally, I'd like to know about the available color options, warranty details, and any bulk purchase discounts you might offer. If you have any certifications or compliance information, that would be great as well. Looking forward to your prompt response with a catalog or data sheet!
