菲律宾采购需求：电动三轮车、载客三轮车

I'm looking for a vehicle that incorporates a low center of gravity design to enhance chassis stability. Stability is crucial for safety, especially when navigating diverse terrains. Additionally, the vehicle should offer ample foot and headroom, with a low footboard that facilitates easy boarding and alighting for passengers. It's vital that the design allows for an extra row of seats within the same dimensions to maximize passenger capacity. The focus on ergonomics and space will be key in providing a comfortable experience for all riders. Please provide information on available options that meet these criteria.
