美国采购需求：有氧运动

I'm reaching out as a purchasing manager for a local gym chain in the US. We are currently looking to expand our fitness equipment offerings and are interested in sourcing curved treadmills. We believe these would greatly enhance our members' workout experiences due to their unique design and benefits. I'd love to hear more about your product range, including specifications, pricing, and any available customization options. Additionally, please share your lead times and policies regarding bulk orders. We're eager to find a reliable partner for this equipment, and I'm looking forward to your detailed response!
